Therapy MULTIPLE CHOICE 1. The 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 the correc t format for a nursing diagnosis? a. Anxiety b. Anxiety related to new drug therapy c. Anxiety related to anxious feelings about drug therapy, as evidenced by statements such as “I’m upset about having to test my blood sugars.” d. Anxiety related to new drug therapy, 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 the “related to” and “as evidenced by” portions of defining characteristics. “Anxiety related to new drug therapy” is missing the “as evidenced by” portion of defining characteristics. The statement beginning “Anxiety related to anxious feelings” is incorrect because the “related to” section is simply a restatemen t of the problem “anxiety,” not a separate factor related to the response.

The patient is to receive oral guaifenesin (Mucinex) twice a day. Today, the nurse was busy and gave the medication 2 hours after the scheduled dose was due. What type of problem does this represent? a. “Right time” b. “Right dose” c. “Right route” d. “Rig ht medication” ANS: A “Right time” is correct because the medication was given more than 30 minutes after the scheduled dose was due. “Dose” is incorrect because the dose is not related to the time the medication administration is scheduled. “Route” is incorrect because the route is not affected. “Medication” is incorrect because the medication ordered will not change. DIF: COGNITIVE LEVEL: Applying (Application) REF: p. 11 TOP: NURSING PROCESS: Implementation MSC: NCLEX: Safe and Effective Care Envir onment: Safety and Infection Control 3. The nurse has been monitoring the patient’s progress on a new drug regimen since the first dose and documenting the patient’s therapeutic response to the medication. Which phase of the nursing process do these acti ons illustrate? a. Nursing diagnosis 5 Chapter 01: The Nursing Process and Drug Therapy b. Planning c. Implementation d. Evaluation ANS: D Monitoring the patient’s progress, including the patient’s response to the medication, is part of the evaluation phase. Planning, implementation, and nursing diag nosis are not illustrated by this example. DIF: COGNITIVE LEVEL: Understanding (Comprehension) REF: pp. 13 -14 TOP: NURSING PROCESS: Evaluation MSC: NCLEX: Safe and Effective Care Environment: Management of Care 4. The 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. The patient will follow instructions. b. The patient will not experience complications. c. The patient will adhere to the new in sulin treatment regimen. d. The 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 experienc ing complications” are not specific criteria. “Adhering to new regimen” would be difficult to measure. DIF: COGNITIVE LEVEL: Applying (Application) REF: p. 8 TOP: NURSING PROCESS: Planning MSC: NCLEX: Safe and Effective Care Environment: Management of Ca re 5. Which activity best reflects the implementation phase of the nursing process for the patient who is newly diagnosed with hypertension? a. Providing education on keeping a journal of blood pressure readings b. Setting goals and outcome criteria wit h the patient’s input c. Recording a drug history regarding over -the-counter medications used at home d. Formulating nursing diagnoses regarding deficient knowledge related to the new treatment regimen ANS: A Education is an intervention that occurs d uring the implementation phase. Setting goals and outcomes reflects the planning phase. Recording a drug history reflects the assessment phase. Formulating nursing diagnoses reflects analysis of data as part of planning. DIF: COGNITIVE LEVEL: Applying (Ap plication) REF: pp. 8 -9 TOP: NURSING PROCESS: Implementation MSC: NCLEX: Safe and Effective Care Environment: Management of Care 6. The medication order reads, “Give ondansetron (Zofran) 4 mg, 30 minutes before beginning chemotherapy to prevent nausea. ” The nurse notes that the route is missing from the order. What is the nurse’s best action? 6 Chapter 01: The Nursing Process and Drug Therapy a. Give the medication intravenously because the patient might vomit. b. Give the medication orally because the tablets are available in 4 -mg doses. c. Contact t he prescriber to clarify the route of the medication ordered. d. Hold the medication until the prescriber returns to make rounds. ANS: C A complete medication order includes the route of administration. If a medication order does not include the route, the nurse must ask the prescriber to clarify it. The intravenous and oral routes are not interchangeable. Holding the medication until the prescriber returns would mean that the patient would not receive a needed medication.

When the nurse considers the timing of a drug dose, which factor is appropriate to consider when deciding when to giv e a drug? a. The patient’s ability to swallow b. The patient’s height c. The patient’s last meal d. The patient’s allergies ANS: C The nurse must consider specific pharmacokinetic/pharmacodynamic drug properties that may be affected by the timing of the last meal. The patient’s ability to swallow, height, and allergies are not factors to consider regarding the timing of the drug’s administration. DIF: COGNITIVE LEVEL: Understanding (Comprehension) REF: p. 12 TOP: NURSING PROCESS: Assessment MSC: NCLEX: Safe and Effective Care Environment: Management of Care 8. The nurse is performing an assessment of a newly admitted patient. Which is an example of subjective data? a. Blood pressure 158/96 mm Hg b. Weight 255 pounds c. The patient reports that he uses the herbal product ginkgo. d. The patient’s laboratory work includes a complete blood count and urinalysis. ANS: C Subjective data include information shared through the spoken word by any reliable source, such as the patient. Objective data ma y be defined as any information gathered through the senses or that which is seen, heard, felt, or smelled. A patient’s blood pressure, weight, and laboratory tests are all examples of objective data.

When giving medications, the nurse will follow the rights of medication administration. The rights include the right doc umentation, the right reason, the right response, and the patient’s right to refuse. Which of these are additional rights? ( Select all that apply .) a. Right drug b. Right route c. Right dose d. Right diagnosis e. Right time f. Right patient ANS: A, B, C, E, F Additional rights of medication administration must always include the right drug, right dose, right time, right route, and right patient. The right diagnosis is incorrect.

The patient is receiving two different drugs. At current dosa ges and dosage forms, both drugs are absorbed into the circulation in identical amounts. Which term is used to identify this principle? a. Bioequivalent b. Synergistic c. Prodrugs d. Steady state ANS: A Two drugs absorbed into the circulation in the same amount (in specific dosage forms) have the same bioavailability; thus, they are bioequivalent. A drug’s steady state is the physiologic state in which the amount of drug removed via elimination is equal to the amount of drug absorbed from each dose. T he term synergistic refers to two drugs, given together, with a resulting effect that is greater than the sum of the effects of each drug given alone. A prodrug is an inactive drug dosage form that is converted to an active metabolite by various biochemica l reactions once it is inside the body. DIF: COGNITIVE LEVEL: Understanding (Comprehension) REF: p. 21 TOP: NURSING PROCESS: Implementation MSC: NCLEX: Physiological Integrity: Pharmacological and Parenteral Therapies 2. When given an intravenous medi cation, the patient says to the nurse, “I usually take pills. Why does this medication have to be given in the arm?” What is the nurse’s best answer? a. “The medication will cause fewer adverse effects when given intravenously.” b. “The intravenous medica tion will have delayed absorption into the body’s tissues.” c. “The action of the medication will begin sooner when given intravenously.” d. “There is a lower chance of allergic reactions when drugs are given intravenously.” ANS: C An intravenous (IV) injection provides the fastest route of absorption. The IV route does not affect the number of adverse effects, nor does it cause delayed tissue absorption (it results in faster absorption). The IV route does not affect the number of allergic reactions. DIF: COGNITIVE LEVEL: Understanding (Comprehension) REF: p. 22 TOP: NURSING PROCESS: Implementation MSC: NCLEX: Physiological Integrity: Pharmacological and Parenteral Therapies 3. The nurse is administering parenteral drugs. Which statement is true re garding parenteral drugs? a. Parenteral drugs bypass the first -pass effect. b. Absorption of parenteral drugs is affected by reduced blood flow to the stomach. c. Absorption of parenteral drugs is faster when the stomach is empty. d. Parenteral drugs ex ert their effects while circulating in the bloodstream. ANS: A 9 Chapter 02: Pharmacologic Principles Drugs given by the parenteral route bypass the first -pass effect. Reduced blood flow to the stomach and the presence of food in the stomach apply to enteral drugs (taken orally), not to parenteral drugs. Parenteral drugs must be absorbed into cells and tissues from the circulation before they can exert their effects; they do not exert their effects while circulating in the bloodstream. DIF: COGNITIVE LEVEL: Understanding (Comprehension) REF: p. 22 TOP: NURSING PROCESS: General MSC: NCLEX: Physiological Integrity: Pharmacological and Parenteral Therapies 4. When monitoring the patient receiving an intravenous infusion to reduce blood pressure, the nurse notes that the patient’s blood pressu re is extremely low, and the 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 pharmacolo gic reaction is an extension of a drug’s normal effects in the body. In this case, the antihypertensive drug lowered the patient’s blood pressure levels too much. The other options do not describe a pharmacologic reaction. An adverse effect is a predictabl e, well -known adverse drug reaction that results in minor or no changes in patient management. An allergic reaction (also known as a hypersensitivity reaction ) involves the patient’s immune system. An idiosyncratic reaction is unexpected and is defined as a genetically determined abnormal response to normal dosages of a drug.

The nu rse is reviewing pharmacology terms for a group of newly graduated nurses. Which sentence defines a drug’s half -life? a. The time it takes for the drug to cause half of its therapeutic response b. The time it takes for one half of the original amount of a drug to reach the target cells c. The time it takes for one half of the original amount of a drug to be removed from the body d. The time it takes for one half of the original amount of a drug to be absorbed into the circulation ANS: C A drug’s half -life is the time it takes for one half of the original amount of a drug to be removed from the body. It is a measure of the rate at which drugs are removed from the body. The other options are incorrect definitions of half -life. DIF: COGNITIVE LEVEL: Unde rstanding (Comprehension) REF: p. 27 TOP: NURSING PROCESS: General MSC: NCLEX: Physiological Integrity: Pharmacological and Parenteral Therapies 10 Chapter 02: Pharmac ologic Principles 6. When administering drugs, the nurse remembers that the duration of action of a drug is defined as which o f these? a. The time it takes for a drug to elicit a therapeutic response b. The amount of time needed to remove a drug from circulation c. The time it takes for a drug to achieve its maximum therapeutic response d. The time period at which a drug’s con centration is sufficient to cause a therapeutic response ANS: D Duration of action is the time during which drug concentration is sufficient to elicit a therapeutic response. The other options do not define duration of action. A drug’s onset of action i s the time it takes for the drug to elicit a therapeutic response. A drug’s peak effect is the time it takes for the drug to reach its maximum therapeutic response. Elimination is the length of time it takes to remove a drug from circulation. DIF: COGNITI VE LEVEL: Understanding (Comprehension) REF: p. 28 TOP: NURSING PROCESS: General MSC: NCLEX: Physiological Integrity: Pharmacological and Parenteral Therapies 7. When reviewing the mechanism of action of a specific drug, the nurse reads that the drug wo rks by selective enzyme interaction. Which of these processes describes selective enzyme interaction? a. The drug alters cell membrane permeability. b. The drug’s effectiveness within the cell walls of the target tissue is enhanced. c. The drug is attrac ted to a receptor on the cell wall, preventing an enzyme from binding to that receptor. d. The drug binds to an enzyme molecule and inhibits or enhances the enzyme’s action with the normal target cell. ANS: D With selective enzyme interaction, the drug attracts the enzymes to bind with the drug instead of allowing the enzymes to bind with their normal target cells. As a result, the target cells are protected from the action of the enzymes. This results in a drug effect. The actions described in the othe r options do not occur with selective enzyme interactions. DIF: COGNITIVE LEVEL: Understanding (Comprehension) REF: p. 29 TOP: NURSING PROCESS: General MSC: NCLEX: Physiological Integrity: Pharmacological and Parenteral Therapies 8. When administering a new medication to a patient, the nurse reads that it is highly protein bound. Assuming that the patient’s albumin levels are normal, the nurse would expect which result, as compared to a medication that is not highly protein bound? a. Renal excretion wil l be faster. b. The drug will be metabolized quickly. c. The duration of action of the medication will be shorter. d. The duration of action of the medication will be longer. ANS: D 11 Chapter 02: Pharmacologic Principles Drugs that are bound to plasma proteins are characterized by longer duration of action. Protein binding does not make renal excretion faster, does not speed up drug metabolism, and does not cause the duration of action to be shorter.

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

The nurse is administering medications to the patient who is in renal failure resulting from end - stage renal disease. The 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 The kidneys are the organs that are most responsible for drug excretion. Renal function does not affect the absorption and distribution of a drug. Renal function may affect metabolism o f drugs to a small extent.

A patient who has advanced cancer is receiving opioi d medications around the clock to keep him comfortable as he nears the end of his life. Which term best describes this type of therapy? a. Palliative therapy b. Maintenance therapy c. Empiric therapy d. Supplemental therapy ANS: A 12 Chapter 02: Pharmacologic Principles The goal of palliat ive therapy is to make the patient as comfortable as possible. It is typically used in the end stages of illnesses when all attempts at curative therapy have failed. Maintenance therapy is used for the treatment of chronic illnesses such as hypertension. E mpiric therapy is based on clinical probabilities and involves drug administration when a certain pathologic condition has an uncertain but high likelihood of occurrence based on the patient’s initial presenting symptoms. Supplemental (or replacement thera py) supplies the body with a substance needed to maintain normal function.

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

The nurse will be injecting a drug into the fatty tissue of the patient’s abdomen. Which ro ute does this describe? a. Intradermal b. Subcutaneous c. Intramuscular d. Transdermal ANS: B Injections into the fatty subcutaneous tissue under the dermal layer of skin are referred to as subcutaneous injections. Injections under the more superfici al skin layers immediately underneath the epidermal layer of skin and into the dermal layer are known as intradermal injections. Injections into the muscle beneath the subcutaneous fatty tissue are referred to as intramuscular injections. Transdermal drugs are applied to the skin via an adhesive patch.

Levothyroxine (Synthroid) tablets e. Transdermal nicotine patches f. Esomeprazole (Nexium) capsules g. Penicillin given by IV piggyback infusion ANS: C, D, F Orally administered drugs (elixirs, tablets, capsules) undergo the first -pass effect because they are metabolized in the liver after being absorbed into the p ortal circulation from the small intestine. IV medications (IV push and IV piggyback) enter the bloodstream directly and do not go directly to the liver. Sublingual tablets and transdermal patches also enter the bloodstream without going directly to the li ver, thus avoiding the first -pass effect.

A drug dose that delivers 250 m g has a half -life of 5 hours. Identify how much drug will remain in the body after one half -life. _______ ANS: 125 mg A drug’s half -life is the time required for one half of an administered dose of a drug to be eliminated by the body, or the time it tak es for the blood level of a drug to be reduced by 50%. Therefore, one half of 250 mg equals 125 mg.

Drug transfer to the fetus is more likely during the last trimester of pregnancy for which reason? a. Decreased fetal surface area b. Increased placental surface area c. Enhanced blood flow to the fetus d. Increased amount of protein -bound drug in maternal circulation ANS: C Drug transfer to the fetus is more likely during the last trimester as a result of enhanced blood flow to the fetus. The other options are incorrect. Incr eased fetal surface area, not decreased, is a factor that affects drug transfer to the fetus. The placenta’s surface area does not increase during this time. Drug transfer is increased because of an increased amount of free drug, not protein - bound drug, in the mother’s circulation.

The nurse is monitoring a patient who is in the 26th week of pregnancy and has develo ped gestational diabetes and pneumonia. She is given medications that pose a possible fetal risk, but the potential benefits may warrant the use of the medications in her situation. The nurse recognizes that these medications are in which U.S. Food and Dru g Administration pregnancy safety category? a. Category X b. Category B c. Category C d. Category D ANS: D Pregnancy category D fits the description given. Category B indicates no risk to animal fetus; information for humans is not available. Categor y C indicates adverse effects reported in animal fetus; information for humans is not available. Category X consists of drugs that should not be used in pregnant women because of reports of fetal abnormalities and positive evidence of fetal risk in humans.

The nurse is assessing a newly admitted 83 -year-old patient and determines that the patient is experiencing polypharmacy. Which statement most a ccurately illustrates polypharmacy? a. The patient is experiencing multiple illnesses. b. The patient uses one medication for an illness several times per day. c. The patient uses over -the-counter drugs for an illness. d. The patient uses multiple medic ations simultaneously. ANS: D Polypharmacy usually occurs when a patient has several illnesses and takes medications for each of them, possibly prescribed by different specialists who may be unaware of other treatments the patient is undergoing. The oth er options are incorrect. Polypharmacy addresses the medications taken, not just the illnesses. Polypharmacy means the patient is taking several different medications, not just one, and can include prescription drugs, over -the-counter medications, and herbal products.
