Chapter 27: Assessment of the Respiratory System Ignatavicius: Medical-Surgical Nursing, 8th Edition MULTIPLE CHOICE 1. A nurse obtains the health history of a client who is recently diagnosed with lung cancer and identifies that the client has a 60pack-year smoking history. Which action is most important for the nurse to take when interviewing this client? a. T ell the client that he needs to quit smoking to stop further cancer development. b. Encourage the client to be completely honest about both tobacco and marijuana use. c. Maintain a nonjudgmental attitude to avoid causing the client to feel guilty. d. Avoid giving the client false hope regarding cancer treatment and prognosis. 2. A nurse assesses a client after an open lung biopsy. Which assessment finding is matched with the correct intervention? a. Client states he is dizzy. Nurse applies oxygen and pulse oximetry. b. Clients heart rate is 55 beats/min. Nurse withholds pain medication. c. Client has reduced breath sounds. Nurse calls physician immediately. d. Clients respiratory rate is 18 breaths/min. Nurse decreases oxygen flow rate. ANS: C A potentially serious complication after biopsy is pneumothorax, which is indicated by decreased or absent breath sounds. The physician needs to be notified immediately. Dizziness after the procedure is not an expected finding. If the clients heart rate is 55 beats/min, no reason is known to withhold pain medication. A respiratory rate of 18 breaths/min is a normal finding and would not warrant changing the oxygen flow rate.TEST BANK ASSESMENT OF THE RESPIRATORY SYSTEM CHAPTER 273. A nurse assesses a clients respiratory status. Which information is of highest priority for the nurse to obtain? a. Average daily fluid intake b. Neck circumference c. Height and weight d. Occupation and hobbies ANS: D Many respiratory problems occur as a result of chronic exposure to inhalation irritants used in a clients occupation and hobbies. Although it will be important for the nurse to assess the clients fluid intake, height, and weight, these will not be as important as determining his occupation and hobbies. Determining the clients neck circumference will not be an important part of a respiratory assessment. 4. A nurse is caring for an older adult client who has a pulmonary infection. Which action should the nurse take first? a. Encourage the client to increase fluid intake. b. Assess the clients level of consciousness. c. Raise the head of the bed to at least 45 degrees. d. Provide the client with humidified oxygen. Assessing the clients level of consciousness will be most important because it will show how the client is responding to the presence of the infection. Although it will be important for the nurse to encourage the client to turn, cough, and frequently breathe deeply; raise the head of the bed; increase oral fluid intake; and humidify the oxygen administered, none of these actions will be as important as assessing the level of consciousness. Also, the client who has a pulmonary infection may not be able to cough effectively if an area of abscess is present. 5. A nurse is providing care after auscultating clients breath sounds. Which assessment finding is correctly matched to the nurses primary intervention? a. Hollow sounds are heard over the trachea. The nurse increases the oxygen flow rate. b. Crackles are heard in bases. The nurse encourages the client to cough forcefully. c. Wheezes are heard in central areas. The nurse administers an inhaled bronchodilator. d. Vesicular sounds are heard over the periphery. The nurse has the client breathe deeply. Wheezes are indicative of narrowed airways, and bronchodilators help to open the air passages. Hollow sounds are typically heard over the trachea, and no intervention is necessary. If crackles are heard, the client may need a diuretic. Crackles represent a deep interstitial process, and coughing forcefully will not help the client expectorate secretions. Vesicular sounds heard in the periphery are normal and require no intervention. 6. A nurse observes that a clients anteroposterior (AP) chest diameter is the same as the lateral chest diameter. Which question should the nurse ask the client in response to this finding? a. Are you taking any medications or herbal supplements? b. Do you have any chronic breathing problems? c. How often do you perform aerobic exercise? d. What is your occupation and what are your hobbies? 7. A nurse is assessing a client who is recovering from a lung biopsy. Which assessment finding requires immediate action? a. Increased temperature b. Absent breath sounds c. Productive cough d. Incisional discomfortANS: B Absent breath sounds may indicate that the client has a pneumothorax, a serious complication after a needle biopsy or open lung biopsy. The other manifestations are not life threatening. 8. A nurse is caring for a client who is scheduled to undergo a thoracentesis. Which intervention should the nurse complete prior to the procedure? a. Measure oxygen saturation before and after a 12-minute walk. b. Verify that the client understands all possible complications. c. Explain the procedure in detail to the client and the family. d. Validate that informed consent has been given by the client. ANS: D A thoracentesis is an invasive procedure with many potentially serious complications. Verifying that the client understands complications and explaining the procedure to be performed will be done by the physician or nurse practitioner, not the nurse. Measurement of oxygen saturation before and after a 12-minute walk is not a procedure unique to a thoracentesis. 9. A nurse assesses a client after a thoracentesis. Which assessment finding warrants immediate action? a. The client rates pain as a 5/10 at the site of the procedure. b. A small amount of drainage from the site is noted. c. Pulse oximetry is 93% on 2 liters of oxygen. d. The trachea is deviated toward the opposite side of the neck. ANS: D A deviated trachea is a manifestation of a tension pneumothorax, which is a medical emergency. The other findings are normal or near normal. 10. A nurse cares for a client who had a bronchoscopy 2 hours ago. The client asks for a drink of water. Which action should the nurse take next? a. Call the physician and request a prescription for food and water. b. Provide the client with ice chips instead of a drink of water. c. Assess the clients gag reflex before giving any food or water.d. Let the client have a small sip to see whether he or she can swallow. ANS: C The topical anesthetic used during the procedure will have affected the clients gag reflex. Before allowing the client anything to eat or drink, the nurse must check for the return of this reflex. 11. A nurse plans care for a client who is experiencing dyspnea and must stop multiple times when climbing a flight of stairs. Which intervention should the nurse include in this clients plan of care? a. Assistance with activities of daily living b. Physical therapy activities every day c. Oxygen therapy at 2 liters per nasal cannula d. Complete bedrest with frequent repositioning ANS: A A client with dyspnea and difficulty completing activities such as climbing a flight of stairs has class III dyspnea. The nurse should provide assistance with activities of daily living. These clients should be encouraged to participate in activities as tolerated. They should not be on complete bedrest, may not be able to tolerate daily physical therapy, and only need oxygen if hypoxia is present. DIF: Applying/Application REF: 503 KEY: Respiratory distress/failure MSC: Integrated Process: Nursing Process: Implementation NOT: Client Needs Category: Physiological Integrity: Basic Care and Comfort 12. A nurse teaches a client who is prescribed nicotine replacement therapy. Which statement should the nurse include in this clients teaching? a. Make a list of reasons why smoking is a bad habit. b. Rise slowly when getting out of bed in the morning. c. Smoking while taking this medication will increase your risk of a stroke. d. Stopping this medication suddenly increases your risk for a heart attack.ANS: C Clients who smoke while using drugs for nicotine replacement therapy increase the risk of stroke and heart attack. Nurses should teach clients not to smoke while taking this drug. The other responses are inappropriate. DIF: Applying/Application REF: 495 KEY: Smoking cessation| medication MSC: Integrated Process: T eaching/Learning NOT: Client Needs Category: Physiological Integrity: Pharmacological and Parenteral Therapies 13. A nurse is caring for a client who received benzocaine spray prior to a recent bronchoscopy. The client presents with continuous cyanosis even with oxygen therapy. Which action should the nurse take next? a. Administer an albuterol treatment. b. Notify the Rapid Response T eam. c. Assess the clients peripheral pulses. d. Obtain blood and sputum cultures. ANS: B Cyanosis unresponsive to oxygen therapy is a manifestation of methemoglobinemia, which is an adverse effect of benzocaine spray. Death can occur if the level of methemoglobin rises and cyanosis occurs. The nurse should notify the Rapid Response T eam to provide advanced nursing care. An albuterol treatment would not address the clients oxygenation problem. Assessment of pulses and cultures will not provide data necessary to treat this client. DIF: Applying/Application REF: 510 KEY: Assessment/diagnostic examination| medication MSC: Integrated Process: Nursing Process: Implementation NOT: Client Needs Category: Physiological Integrity: Pharmacological and Parenteral Therapies14. A nurse auscultates a harsh hollow sound over a clients trachea and larynx. Which action should the nurse take first? a. Document the findings. b. Administer oxygen therapy. c. Position the client in high-Fowlers position. d. Administer prescribed albuterol. ANS: A Bronchial breath sounds, including harsh, hollow, tubular, and blowing sounds, are a normal finding over the trachea and larynx. The nurse should document this finding. There is no need to implement oxygen therapy, administer albuterol, or change the clients position because the finding is normal. DIF: Remembering/Knowledge REF: 506 KEY: Assessment/diagnostic examination MSC: Integrated Process: Communication and Documentation NOT: Client Needs Category: Physiological Integrity: Physiological Adaptation MULTIPLE RESPONSE 1. A nurse assesses a client who is prescribed varenicline (Chantix) for smoking cessation. Which manifestations should the nurse identify as adverse effects of this medication? (Select all that apply.) a. Visual hallucinations b. Tachycardia c. Decreased cravings d. Impaired judgment e. Increased thirst ANS: A, D Varenicline (Chantix) has a black box warning stating that the drug can cause manic behavior and hallucinations. The nurse should assess for changes in behavior and thought processes, including impaired judgment and visual hallucinations. T achycardia and increased thirst are not adverseeffects of this medication. Decreased cravings is a therapeutic response to this medication. 2. A nurse plans care for a client who is at high risk for a pulmonary infection. Which interventions should the nurse include in this clients plan of care? (Select all that apply.) a. Encourage deep breathing and coughing. b. Implement an air mattress overlay. c. Ambulate the client three times each day. d. Provide a diet high in protein and vitamins. e. Administer acetaminophen (Tylenol) twice daily. ANS: A, C, D Regular pulmonary hygiene and activities to maintain health and fitness help to maximize functioning of the respiratory system and prevent infection. A client at high risk for a pulmonary infection may need a specialty bed to help with postural drainage or percussion; this would not include an air mattress overlay, which is used to prevent pressure ulcers. Tylenol would not decrease the risk of a pulmonary infection. 3. While obtaining a clients health history, the client states, I am allergic to avocados. Which responses by the nurse are best? (Select all that apply.) a. What response do you have when you eat avocados? b. I will remove any avocados that are on your lunch tray. c. When was the last time you ate foods containing avocados? d. I will document this in your record so all of your providers will know. e. Have you ever been treated for this allergic reaction? ANS: A, D, E Nurses should assess clients who have allergies for the specific cause, treatment, and response to treatment. The nurse should also document the allergies in a prominent place in the clients medical record. The nurse should collaborate with food services to ensure no avocados are placed on the clients meal trays. Asking about the last time the client ate avocados does not provide any pertinent information for the clients plan of care.4. A nurse collaborates with a respiratory therapist to complete pulmonary function tests (PFT s) for a client. Which statements should the nurse include in communications with the respiratory therapist prior to the tests? (Select all that apply.) a. I held the clients morning bronchodilator medication. b. The client is ready to go down to radiology for this examination. c. Physical therapy states the client can run on a treadmill. d. I advised the client not to smoke for 6 hours prior to the test. e. The client is alert and can follow your commands. T o ensure the PFT s are accurate, the therapist needs to know that no bronchodilators have been administered in the past 4 to 6 hours, the client did not smoke within 6 to 8 hours prior to the test, and the client can follow basic commands, including different breathing maneuvers. The respiratory therapist can perform PFT s at the bedside. A treadmill is not used for this test. 5. A nurse teaches a client who is interested in smoking cessation. Which statements should the nurse include in this clients teaching? (Select all that apply.) a. Find an activity that you enjoy and will keep your hands busy. b. Keep snacks like potato chips on hand to nibble on. c. Identify a punishment for yourself in case you backslide. d. Drink at least eight glasses of water each day. e. Make a list of reasons you want to stop smoking. ANS: A, D, E The nurse should teach a client who is interested in smoking cessation to find an activity that keeps the hands busy, to keep healthy snacks on hand to nibble on, to drink at least 8 glasses of water each day, and to make a list of reasons for quitting smoking. The nurse should also encourage the client not to be upset if he or she backslides and has a cigarette.Chapter 28: Care of Patients Requiring Oxygen Therapy or Tracheostomy Ignatavicius: Medical-Surgical Nursing, 8th Edition MULTIPLE CHOICE 1. A nursing student caring for a client removes the clients oxygen as prescribed. The client is now breathing what percentage of oxygen in the room air? a. 14% b. 21% c. 28% d. 31% ANS: B Room air is 21% oxygen. 2. A client is scheduled to have a tracheostomy placed in an hour. What action by the nurse is the priority? a. Administer prescribed anxiolytic medication. b. Ensure informed consent is on the chart. c. Reinforce any teaching done previously. d. Start the preoperative antibiotic infusion. ANS: B Since this is an operative procedure, the client must sign an informed consent, which must be on the chart. Giving anxiolytics and antibiotics and reinforcing teaching may also be required but do not take priority. 3. A client has a tracheostomy that is 3 days old. Upon assessment, the nurse notes the clients face is puffy and the eyelids are swollen. What action by the nurse takes priority? a. Assess the clients oxygen saturation. b. Notify the Rapid Response T eam. c. Oxygenate the client with a bag-valve-mask. d. Palpate the skin of the upper chest. ANS: AThis client may have subcutaneous emphysema, which is air that leaks into the tissues surrounding the tracheostomy. The nurse should first assess the clients oxygen saturation and other indicators of oxygenation. If the client is stable, the nurse can palpate the skin of the upper chest to feel for the air. If the client is unstable, the nurse calls the Rapid Response T eam. Using a bag-valve-mask device may or may not be appropriate for the unstable client. 4. A client has a tracheostomy tube in place. When the nurse suctions the client, food particles are noted. What action by the nurse is best? a. Elevate the head of the clients bed. b. Measure and compare cuff pressures. c. Place the client on NPO status. d. Request that the client have a swallow study. ANS: B Constant pressure from the tracheostomy tube cuff can cause tracheomalacia, leading to dilation of the tracheal passage. This can be manifested by food particles seen in secretions or by noting that larger and larger amounts of pressure are needed to keep the tracheostomy cuff inflated. The nurse should measure the pressures and compare them to previous ones to detect a trend. Elevating the head of the bed, placing the client on NPO status, and requesting a swallow study will not correct this situation. 5. An unlicensed assistive personnel (UAP) was feeding a client with a tracheostomy. Later that evening, the UAP reports that the client had a coughing spell during the meal. What action by the nurse takes priority? a. Assess the clients lung sounds. b. Assign a different UAP to the client. c. Report the UAP to the manager. d. Request thicker liquids for meals. ANS: A The priority is to check the clients oxygenation because he or she may have aspirated. Once the client has been assessed, the nurse can consult with the registered dietitian about appropriately thickened liquids. The UAP should have reported the incident immediately, but addressing that issue is not the immediate priority. 6. A student nurse is providing tracheostomy care. What action by the student requires intervention by the instructor? a. Holding the device securely when changing ties b. Suctioning the client first if secretions are present c. Tying a square knot at the back of the neck d. Using half-strength peroxide for cleansing ANS: C T o prevent pressure ulcers and for client safety, when ties are used that must be knotted, the knot should be placed at the side of the clients neck, not in back. The other actions are appropriate. 7. A student is practicing suctioning a tracheostomy in the skills laboratory. What action by the student demonstrates that more teaching is needed? a. Applying suction while inserting the catheter b. Preoxygenating the client prior to suctioning c. Suctioning for a total of three times if needed d. Suctioning for only 10 to 15 seconds each time ANS: A Suction should only be applied while withdrawing the catheter. The other actions are appropriate. 8. A nurse is caring for a client using oxygen while in the hospital. What assessment finding indicates that goals for a priority diagnosis are being met? a. 100% of meals being eaten by the client b. Intact skin behind the ears c. The client understanding the need for oxygen d. Unchanged weight for the past 3 days ANS: B Oxygen tubing can cause pressure ulcers, so clients using oxygen have the nursing diagnosis of Risk for Impaired Skin Integrity. Intact skin behind the ears indicates that goals for this diagnosis are being met. Nutrition and weight are not related to using oxygen. Understanding the need for oxygen is important but would not take priority over a physical problem. 9. A nurse is assessing a client who has a tracheostomy. The nurse notes that the tracheostomy tube is pulsing with the heartbeat as the clients pulse is being taken. No other abnormal findings are noted. What action by the nurse is most appropriate? a. Call the operating room to inform them of a pending emergency case. b. No action is needed at this time; this is a normal finding in some clients. c. Remove the tracheostomy tube; ventilate the client with a bag-valve- mask. d. Stay with the client and have someone else call the provider immediately. ANS: D This client may have a tracheainnominate artery fistula, which can be a life-threatening emergency if the artery is breached and the client begins to hemorrhage. Since no bleeding is yet present, the nurse stays with the client and asks someone else to notify the provider. If the client begins hemorrhaging, the nurse removes the tracheostomy and applies pressure at the bleeding site. The client will need to be prepared for surgery. 10. A client with a new tracheostomy is being seen in the oncology clinic. What finding by the nurse best indicates that goals for the nursing diagnosis Impaired Self-Esteem are being met? a. The client demonstrates good understanding of stoma care. b. The client has joined a book club that meets at the library. c. Family members take turns assisting with stoma care. d. Skin around the stoma is intact without signs of infection. ANS: B The client joining a book club that meets outside the home and requires him or her to go out in public is the best sign that goals for Impaired Self-Esteem are being met. The other findings are all positive signs but do not relate to this nursing diagnosis. 11. A client is receiving oxygen at 4 liters per nasal cannula. What comfort measure may the nurse delegate to unlicensed assistive personnel (UAP)? a. Apply water-soluble ointment to nares and lips. b. Periodically turn the oxygen down or off. c. Remove the tubing from the clients nose. d. Turn the client every 2 hours or as needed. ANS: A Oxygen can be drying, so the UAP can apply water-soluble lubricant to the clients lips and nares. The UAP should not adjust the oxygen flow rate or remove the tubing. Turning the client is not related to comfort measures for oxygen. 12. A client is wearing a Venturi mask to deliver oxygen and the dinner tray has arrived. What action by the nurse is best? a. Assess the clients oxygen saturation and, if normal, turn off the oxygen. b. Determine if the client can switch to a nasal cannula during the meal. c. Have the client lift the mask off the face when taking bites of food. d. Turn the oxygen off while the client eats the meal and then restart it. ANS: B Oxygen is a drug that needs to be delivered constantly. The nurse should determine if the provider has approved switching to a nasal cannula during meals. If not, the nurse should consult with the provider about this issue. The oxygen should not be turned off. Lifting the mask to eat will alter the FiO2 delivered. 13. The nurse assesses the client using the device pictured below to deliver 50% O2: The nurse finds the mask fits snugly, the skin under the mask and straps is intact, and the flow rate of the oxygen is 3 L/min. What action by the nurse is best? a. Assess the clients oxygen saturation.b. Document these findings in the chart. c. Immediately increase the flow rate. d. Turn the flow rate down to 2 L/min. ANS: C For the Venturi mask to deliver high flow of oxygen, the flow rate must be set correctly, usually between 4 and 10 L/min. The clients flow rate is too low and the nurse should increase it. After increasing the flow rate, the nurse assesses the oxygen saturation and documents the findings. MULTIPLE RESPONSE 1. A home health nurse is visiting a new client who uses oxygen in the home. For which factors does the nurse assess when determining if the client is using the oxygen safely? (Select all that apply.) a. The client does not allow smoking in the house . b. Electrical cords are in good working order. c. Flammable liquids are stored in the garage. d. Household light bulbs are the fluorescent type. e. The client does not have pets inside the home. ANS: A, B, C Oxygen is an accelerant, which means it enhances combustion, so precautions are needed whenever using it. The nurse should assess if the client allows smoking near the oxygen, whether electrical cords are in good shape or are frayed, and if flammable liquids are stored (and used) in the garage away from the oxygen. Light bulbs and pets are not related to oxygen safety. 2. A nurse is caring for a client who has a tracheostomy tube. What actions may the nurse delegate to unlicensed assistive personnel (UAP)? (Select all that apply.) a. Applying water-soluble lip balm to the clients lips b. Ensuring the humidification provided is adequate c. Performing oral care with alcohol-based mouthwash d. Reminding the client to cough and deep breathe often e. Suctioning excess secretions through the tracheostomyANS: A, D The UAP can perform hygiene measures such as applying lip balm and reinforce teaching such as reminding the client to perform coughing and deep-breathing exercises. Oral care can be accomplished with normal saline, not products that dry the mouth. Ensuring the humidity is adequate and suctioning through the tracheostomy are nursing functions. 3. A client is being discharged home after having a tracheostomy placed. What suggestions does the nurse offer to help the client maintain self- esteem? (Select all that apply.) a. Create a communication system. b. Dont go out in public alone. c. Find hobbies to enjoy at home. d. Try loose-fitting shirts with collars. e. Wear fashionable scarves. ANS: A, D, E The client with a tracheostomy may be shy and hesitant to go out in public. The client should have a sound communication method to ease frustration. The nurse can also suggest ways of enhancing appearance so the client is willing to leave the house. These can include wearing scarves and loose-fitting shirts to hide the stoma. Keeping the client homebound is not good advice. 4. A nurse is planning discharge teaching on tracheostomy care for an older client. What factors does the nurse need to assess before teaching this particular client? (Select all that apply.) a. Cognition b. Dexterity c. Hydration d. Range of motion e. Vision ANS: A, B, D, E The older adult is at risk for having impairments in cognition, dexterity, range of motion, and vision that could limit the ability to perform tracheostomy care and should be assessed. Hydration is not directly related to the ability to perform self-care. 5. A nurse is teaching a client about possible complications and hazards of home oxygen therapy. About which complications does the nurse plan to teach the client? (Select all that apply.) a. Absorptive atelectasis b. Combustion c. Dried mucous membranes d. Oxygen-induced hyperventilation e. T oxicity ANS: A, B, C, E Complications of oxygen therapy include absorptive atelectasis, combustion, dried mucous membranes, and oxygen toxicity. Oxygen- induced hypoventilation is also a complication.Chapter 32: Care of Critically Ill Patients with Respiratory Problems Ignatavicius: Medical-Surgical Nursing, 8th Edition MULTIPLE CHOICE 1.A nurse answers a call light and finds a client anxious, short of breath, reporting chest pain, and having a blood pressure of 88/52 mm Hg on the cardiac monitor. What action by the nurse takes priority? a. Assess the clients lung sounds. b. Notify the Rapid Response T eam. c. Provide reassurance to the client. d. T ake a full set of vital signs. ANS: B This client has manifestations of a pulmonary embolism, and the most critical action is to notify the Rapid Response T eam for speedy diagnosis and treatment. The other actions are appropriate also but are not the priority. DIF:Remembering/KnowledgeREF:605 KEY: Critical rescue| Rapid Response T eam| thromboembolic event| pulmonary embolism MSC:Integrated Process: Communication and Documentation NOT: Client Needs Category: Physiological Integrity: Physiological Adaptation2.A client is admitted with a pulmonary embolism (PE). The client is young, healthy, and active and has no known risk factors for PE. What action by the nurse is most appropriate? a.Encourage the client to walk 5 minutes each hour. b.Refer the client to smoking cessation classes. c.T each the client about factor V Leiden testing. d.T ell the client that sometimes no cause for disease is found. ANS: C Factor V Leiden is an inherited thrombophilia that can lead to abnormal clotting events, including PE. A client with no known risk factors for this disorder should be referred for testing. Encouraging the client to walk is healthy, but is not related to the development of a PE in this case, nor is smoking. Although there are cases of disease where no cause is ever found, this assumption is premature. DIF:Applying/ApplicationREF:605 KEY: Pulmonary embolism| thrombotic events| patient education| genetic testing MSC:Integrated Process: T eaching/Learning NOT: Client Needs Category: Physiological Integrity: Reduction of Risk Potential 3.A client has a pulmonary embolism and is started on oxygen. The student nurse asks why the clients oxygen saturation has not significantly improved. What response by the nurse is best? a.Breathing so rapidly interferes with oxygenation. b.Maybe the client has respiratory distress syndrome. c.The blood clot interferes with perfusion in the lungs. d.The client needs immediate intubation and mechanical ventilation. ANS: CA large blood clot in the lungs will significantly impair gas exchange and oxygenation. Unless the clot is dissolved, this process will continue unabated. Hyperventilation can interfere with oxygenation by shallow breathing, but there is no evidence that the client is hyperventilating, and this is also not the most precise physiologic answer. Respiratory distress syndrome can occur, but this is not as likely. The client may need to be mechanically ventilated, but without concrete data on FiO 2 and SaO2, the nurse cannot make that judgment. DIF:Applying/ApplicationREF:603 KEY: Pulmonary embolism| thromboembolic event| respiratory system| oxygen saturation MSC:Integrated Process: T eaching/Learning NOT: Client Needs Category: Physiological Integrity: Physiological Adaptation 4.A client is on intravenous heparin to treat a pulmonary embolism. The clients most recent partial thromboplastin time (PTT) was 25 seconds. What order should the nurse anticipate? a. Decrease the heparin rate. b. Increase the heparin rate. c. No change to the heparin rate. d. Stop heparin; start warfarin (Coumadin). ANS: B For clients on heparin, a PTT of 1.5 to 2.5 times the normal value is needed to demonstrate the heparin is working. A normal PTT is 25 to 35 seconds, so this clients PTT value is too low. The heparin rate needs to be increased. Warfarin is not indicated in this situation. DIF:Applying/ApplicationREF:606 KEY: Pulmonary embolism| thromboembolic events| anticoagulants| laboratory valuesMSC:Integrated Process: Nursing Process: Analysis NOT: Client Needs Category: Physiological Integrity: Reduction of Risk Potential 5.A client is hospitalized with a second episode of pulmonary embolism (PE). Recent genetic testing reveals the client has an alteration in the gene CYP2C19. What action by the nurse is best? a.Instruct the client to eliminate all vitamin K from the diet. b.Prepare preoperative teaching for an inferior vena cava (IVC) filter. c.Refer the client to a chronic illness support group. d.T each the client to use a soft-bristled toothbrush. ANS: B Often clients are discharged from the hospital on warfarin (Coumadin) after a PE. However, clients with a variation in the CYP2C19 gene do not metabolize warfarin well and have higher blood levels and more side effects. This client is a poor candidate for warfarin therapy, and the prescriber will most likely order an IVC filter device to be implanted. The nurse should prepare to do preoperative teaching on this procedure. It would be impossible to eliminate all vitamin K from the diet. A chronic illness support group may be needed, but this is not the best intervention as it is not as specific to the client as the IVC filter. A soft-bristled toothbrush is a safety measure for clients on anticoagulation therapy.

Which laboratory value possibly indicates that a serious side effect has occurred?a. Hemoglobin: 14.2 g/dL b. Platelet count: 82,000/L c. Red blood cell count: 4.8/mm 3 d. White blood cell count: 8.7/mm 3 ANS: B This platelet count is low and could indicate heparin-induced thrombocytopenia. The other values are normal for either gender.

What action by the nurse is best? a.Assess for other manifestations of hypoxia. b.Change the sensor on the pulse oximeter. c.Obtain a new oximeter from central supply. d.T ell the client to take slow, deep breaths. ANS: A Pulse oximetry is not always the most accurate assessment tool for hypoxia as many factors can interfere, producing normal or near-normal readings in the setting of hypoxia. The nurse should conduct a more thorough assessment. The other actions are not appropriate for a hypoxic client.

The provider has been attempting to intubate for 40 seconds. What action by the nurse takes priority? a. Ensure the client has adequate sedation. b. Find another provider to intubate. c. Interrupt the procedure to give oxygen. d. Monitor the clients oxygen saturation. ANS: C Each intubation attempt should not exceed 30 seconds (15 is preferable) as it causes hypoxia. The nurse should interrupt the intubation attempt and give the client oxygen. The nurse should also have adequate sedation during the procedure and monitor the clients oxygen saturation, but these do not take priority. Finding another provider is not appropriate at this time.

What action by the nurse takes priority? a. Determine if the tube is kinked. b. Ensure all connections are patent. c. Listen to the clients lung sounds. d. Suction the endotracheal tube. ANS: CWhen an intubated client shows signs of hypoxia, check for DOPE: displaced tube (most common cause), obstruction (often by secretions), pneumothorax, and equipment problems. The nurse listens for equal, bilateral breath sounds first to determine if the endotracheal tube is still correctly placed. If this assessment is normal, the nurse would follow the mnemonic and assess the patency of the tube and connections and perform suction.
