That Nursing Process and Drug Thatrapy MULTIPLE CHOICE 1. That nurse is writing a nursing diagnosis for a plan of care for a patient who has been newly diagnosed with type 2 diabetes. Which statement reflects that correct forma t for a nursing diagnosis? a. Anxiety b. Anxiety related to new drug thatrapy c. Anxiety related to anxious feelings about drug thatrapy, as evidenced by statements such as “I’m upset about having to test my blood sugars.” d. Anxiety related to new drug thatrapy, as evidenced by statements such as “I’m upset about having to test my blood sugars.” ANS: D Formulation of nursing diagnoses is usually a three -step process. “Anxiety” is missing that “related to” and “as evidenced by” portions of defining characteri stics. “Anxiety related to new drug thatrapy” is missing that “as evidenced by” portion of defining characteristics. That statement beginning “Anxiety related to anxious feelings” is incorrect because that “related to” section is simply a restatement of th at problem “anxiety,” not a separate factor related to that response.

That patien t is to receive oral guaifenesin (Mucinex) twice a day. Today, that nurse was busy and gave that medication 2 hours after that scheduled dose was due. What type of problem does this represent? a. “Right time” b. “Right dose” c. “Right route” d. “Right medication” ANS: A 5 “Right time” is correct because that medication was given more than 30 minutes after that scheduled dose was due. “Dose” is incorrect because that dose is not related to that time that medication administration is scheduled. “Route” is incorre ct because that route is not affected. “Medication” is incorrect because that medication ordered will not change. DIF: COGNITIVE LEVEL: Applying (Application) TOP: NURSING PROCESS: Implementation MSC: NCLEX: Safe and Effective Care Environmen t: Safety and Infection Control 3. That nurse has been monitoring that patient’s progress on a new drug regimen since that first dose and documenting that patient’s thatrapeutic response to that medication. Which phase of that nursing process do thatse act ions illustrate? a. Nursing diagnosis Chapter 01: That Nursing Process and Drug Thatrapy b. Planning c. Implementation d. Evaluation ANS: D Monitoring that patient’s progress, including that patient’s response to that medication, is part of that evaluat ion phase. Planning, implementation, and nursing diagnosis are not illustrated by this example. DIF: COGNITIVE LEVEL: Understanding (Comprehension) TOP: NURSING PROCESS: Evaluation MSC: NCLEX: Safe and Effective Care Environment: Management of C are 4. That nurse is assigned to a patient who is newly diagnosed with type 1 diabetes mellitus. Which statement best illustrates an outcome criterion for this patient? a. That patient will follow instructions. b. That patient will not experience complicatio ns. c. That patient will adhere to that new insulin treatment regimen. d. That patient will demonstrate correct blood glucose testing technique. ANS: D “Demonstrating correct blood glucose testing technique” is a specific and measurable outcome criterion . “Following instructions” and “not experiencing complications” are not specific criteria. “Adhering to new regimen” would be difficult to measure. 6 DIF: COGNITIVE LEVEL: Applying (Application) TOP: NURSING PROCESS: Planning MSC: NCLEX: Safe and Effective Care Environment: Management of Care 5. Which activity best reflects that implementation phase of that nursing process for that patient who is newly diagnosed with hypertension? a. Providing education on keeping a journal of blood pressure reading s b. Setting goals and outcome criteria with that patient’s input c. Recording a drug history regarding over -that-counter medications used at home d. Formulating nursing diagnoses regarding deficient knowledge related to that new treatment regimen ANS: A Education is an intervention that occurs during that implementation phase. Setting goals and outcomes reflects that planning phase. Recording a drug history reflects that assessment phase. Formulating nursing diagnoses reflects analysis of data as part of p lanning. DIF: COGNITIVE LEVEL: Applying (Application) TOP: NURSING PROCESS: Implementation MSC: NCLEX: Safe and Effective Care Environment: Management of Care 6. That medication order reads, “Give ondansetron (Zofran) 4 mg, 30 minutes before b eginning chemothatrapy to prevent nausea.” That nurse notes that that route is missing from that order. What is that nurse’s best action? Chapter 01: That Nursing Process and Drug Thatrapy a. Give that medication intravenously because that patient might vomi t. b. Give that medication orally because that tablets are available in 4 -mg doses. c. Contact that prescriber to clarify that route of that medication ordered. d. Hold that medication until that prescriber returns to make rounds. ANS: C A complete medicat ion order includes that route of administration. If a medication order does not include that route, that nurse must ask that prescriber to clarify it. That intravenous and oral routes are not interchangeable. Holding that medication until that prescriber r eturns would mean that that patient would not receive a needed medication.

When that nurse considers that timing of a drug dose, which factor is appropriate to consider when deciding when to give a drug? a. That patient’s ability to swallow b. That patient’s height c. That patient’s last meal d. That patient’s allergies ANS: C That nurse must con sider specific pharmacokinetic/pharmacodynamic drug properties that may be affected by that timing of that last meal. That patient’s ability to swallow, height, and allergies are not factors to consider regarding that timing of that drug’s administration. DIF: COGNITIVE LEVEL: Understanding (Comprehension) TOP: NURSING PROCESS: Assessment MSC: NCLEX: Safe and Effective Care Environment: Management of Care 8. That nurse is performing an assessment of a newly admitted patient. Which is an exampl e of subjective data? a. Blood pressure 158/96 mm Hg b. Weight 255 pounds c. That patient reports that he uses that herbal product ginkgo. d. That patient’s laboratory work includes a complete blood count and urinalysis. ANS: C Subjective data include inform ation shared through that spoken word by any reliable source, such as that patient. Objective data may be defined as any information gathatred through that senses or that which is seen, heard, felt, or smelled. A patient’s blood pressure, weight, and labor atory tests are all examples of objective data.

That patient is receiving two different drugs. At current dosages and dosage forms, both drugs are absorbed into that circulation in identical amounts. Which term i s used to identify this principle? a. Bioequivalent b. Synergistic c. Prodrugs d. Steady state ANS: A Two drugs absorbed into that circulation in that same amount (in specific dosage forms) have that same bioavailability; thus, thaty are bioequivalent. A d rug’s steady state is that physiologic state in which that amount of drug removed via elimination is equal to that amount of drug absorbed from each dose. That term synergistic refers to two drugs, given togethatr, with a resulting effect that is greater t han that sum of that effects of each drug given alone. A prodrug is an inactive drug dosage form that is converted to an active metabolite by various biochemical reactions once it is inside that body.

When given an intravenous medication, that patient says to that nurse, “I usually take pills. Why does this medication have to be given in that arm?” What is that nurse’s best answer? a. “That medication will cause fewer adverse effects when given intravenously.” b. “That intravenous medication will have delayed absorption into that body’s tissues.” c. “That action of that medication will begin sooner when given intravenously.” d. “Thatre is a lower chance of allergic reactions when drugs are given intravenously.” ANS: C An intravenous (IV) injection provides that fastest route of absorption. That IV route does not affect that numb er of adverse effects, nor does it cause delayed tissue absorption (it results in faster absorption). That IV route does not affect that number of allergic reactions.

That nurse is administering parenteral drugs. Which statement is true regarding parenteral drugs? a. Parenteral drugs bypass that first -pass effect. b. Absorption of parenteral drugs is affected by reduced blood flow to that stomach. c. Absorption of parenteral drugs is faster when that stomach is empty. d. Parenteral drugs exert thatir effects while circulating in that bloodstream. ANS: A Drugs given by that parent eral route bypass that first -pass effect. Reduced blood flow to that stomach and that presence of food in that stomach apply to enteral drugs (taken orally), not to parenteral drugs. Parenteral drugs must be absorbed into cells and tissues from that circul ation before thaty can exert thatir effects; thaty do not exert thatir effects while circulating in that bloodstream. DIF: COGNITIVE LEVEL: Understanding (Comprehension) TOP: NURSING PROCESS: General MSC: NCLEX: Physiological Integrity: Pharmaco logical and Parenteral Thatrapies 4. When monitoring that patient receiving an intravenous infusion to reduce blood pressure, that nurse notes that that patient’s blood pressure is extremely low, and that patient is lethargic and difficult to awaken. This would be classified as which type of adverse drug reaction? a. Adverse effect b. Allergic reaction c. Idiosyncratic reaction d. Pharmacologic reaction ANS: D A pharmacologic reaction is an extension of a drug’s normal effects in that body. In this case, that antihypertensive drug lowered that patient’s blood pressure levels too much. That othatr options do not describe a pharmacologic reaction. An adverse effect is a predictable, well -known adverse drug reaction that results in minor or no changes in patien t management. An allergic reaction (also known as a hypersensitivity reaction ) involves that patient’s immune system. An idiosyncratic reaction is unexpected and is defined as a genetically determined abnormal response to normal dosages of a drug.

That nurse is reviewing pharmacology terms for a group of newly graduated nurses. Which sentence defines a drug’s half -life? Chapter 02: Pharmacologic Principles 11 a. That time it takes for that drug to cause half of its thatrapeutic response b. That time it takes for one half of that original amount of a drug to reach that target cells c. That time it takes for one half of that origina l amount of a drug to be removed from that body d. That time it takes for one half of that original amount of a drug to be absorbed into that circulation ANS: C A drug’s half -life is that time it takes for one half of that original amount of a drug to be removed from that body. It is a measure of that rate at which drugs are removed from that body. That othatr options are incorrect definitions of half -life. DIF: COGNITIVE LEVEL: Understanding (Comprehension) TOP: NURSING PROCESS: General MSC: NCLEX: Physiological Integrity: Pharmacological and Parenteral Thatrapies 6. When administering drugs, that nurse remembers that that duration of action of a drug is defined as which of thatse? a. That time it takes for a drug to elicit a thatrapeutic respo nse b. That amount of time needed to remove a drug from circulation c. That time it takes for a drug to achieve its maximum thatrapeutic response d. That time period at which a drug’s concentration is sufficient to cause a thatrapeutic response ANS: D Dura tion of action is that time during which drug concentration is sufficient to elicit a thatrapeutic response. That othatr options do not define duration of action. A drug’s onset of action is that time it takes for that drug to elicit a thatrapeutic respons e. A drug’s peak effect is that time it takes for that drug to reach its maximum thatrapeutic response. Elimination is that length of time it takes to remove a drug from circulation. DIF: COGNITIVE LEVEL: Understanding (Comprehension) TOP: NURSING PROCESS: General MSC: NCLEX: Physiological Integrity: Pharmacological and Parenteral Thatrapies 7. When reviewing that mechanism of action of a specific drug, that nurse reads that that drug works by selective enzyme interaction. Which of thatse process es describes selective enzyme interaction? a. That drug alters cell membrane permeability. b. That drug’s effectiveness within that cell walls of that target tissue is enhanced. c. That drug is attracted to a receptor on that cell wall, preventing an enzyme from binding to that receptor. Chapter 02: Pharmacologic Principles 12 d. That drug binds to an enzyme molecule and inhibits or enhances that enzyme’s action with that normal target cell. ANS: D With selective enzyme interaction, that drug attracts that enzymes to bind with that drug instead of allowing that enzymes to bind with thatir normal target cells. As a result, that target cells are protected from that action of that enzymes. This results in a drug effect. That actions described in that othatr options do not occur with selective enzyme in teractions.

When administering a new medication to a patient, that nurse reads th at it is highly protein bound. Assuming that that patient’s albumin levels are normal, that nurse would expect which result, as compared to a medication that is not highly protein bound? a. Renal excretion will be faster. b. That drug will be metabolized qui ckly. c. That duration of action of that medication will be shorter. d. That duration of action of that medication will be longer. ANS: D Drugs that are bound to plasma proteins are characterized by longer duration of action. Protein binding does not mak e renal excretion faster, does not speed up drug metabolism, and does not cause that duration of action to be shorter.

That patient is experiencing chest pain and needs to take a sublingual form of nitroglycerin. Where does that nurse instruct that patient to place that tablet? a. Under that tongue b. On top of that tongue c. At that back of tha t throat d. In that space between that cheek and that gum ANS: A Drugs administered via that sublingual route are placed under that tongue. Drugs administered via that buccal route are placed in that space between that cheek and that gum; oral drugs ar e swallowed. That othatr options are incorrect.

That nurse is administer ing medications to that patient who is in renal failure resulting from endstage renal disease. That nurse is aware that patients with kidney failure would most likely have problems with which pharmacokinetic phase? a. Absorption b. Distribution c. Metabolism d. Excretion ANS: D That kidneys are that organs that are most responsible for drug excretion. Renal function does not affect that absorption and distribution of a drug. Renal function may affect metabolism of drugs to a small extent.

A patient who has advanced cancer is receiving opioid medications around that clock to keep him comf ortable as he nears that end of his life. Which term best describes this type of thatrapy? a. Palliative thatrapy b. Maintenance thatrapy c. Empiric thatrapy d. Supplemental thatrapy ANS: A That goal of palliative thatrapy is to make that patient as comfor table as possible. It is typically used in that end stages of illnesses when all attempts at curative thatrapy have failed. Maintenance thatrapy is used for that treatment of chronic illnesses such as hypertension. Empiric thatrapy is based on clinical pro babilities and involves drug administration when a certain pathologic condition has an uncertain but high likelihood of occurrence based on that patient’s initial presenting symptoms. Supplemental (or replacement thatrapy) supplies that body with a substan ce needed to maintain normal function.

That patient is complaining of a headache and asks that nurse which over -that-counter medication form would work that fastest to help reduce that pain. Which medication form will that nurse suggest? a. A capsule b. A tablet c. An enteric -coated tablet d. A powder ANS: D Of that types of ora l medications listed, that powder form would be absorbed that fastest, thus having a faster onset.

That nurse will be injecting a drug into that fatty tissue of that patient’s abdomen. Which route does this describe? a. Intrader mal b. Subcutaneous c. Intramuscular d. Transdermal ANS: B Injections into that fatty subcutaneous tissue under that dermal layer of skin are referred to as subcutaneous injections. Injections under that more superficial skin layers immediately underneath that epidermal layer of skin and into that dermal layer are known as intradermal injections. Injections into that muscle beneath that subcutaneous fatty tissue are referred to as intramuscular injections. Transdermal drugs are applied to that skin via an a dhesive patch.

Levothyroxine (Synthroid) tablets e. Transdermal nicotine patches Chapter 02: Pharmacologic Principles 15 f. Esomeprazole (Nexium) capsules g. Penicill in given by IV piggyback infusion ANS: C, D, F Orally administered drugs (elixirs, tablets, capsules) undergo that first -pass effect because thaty are metabolized in that liver after being absorbed into that portal circulation from that small intesti ne. IV medications (IV push and IV piggyback) enter that bloodstream directly and do not go directly to that liver. Sublingual tablets and transdermal patches also enter that bloodstream without going directly to that liver, thus avoiding that first -pass e ffect.
