Pharmacology HESI 55 Questions 2023
1. A client with a history of chronic kidney disease is prescribed epoetin alfa. The nurse should monitor for which potential adverse effect?
- A. Hypertension
- B. Hypotension
- C. Hyperglycemia
- D. Tachycardia
Correct answer: A
Rationale: The correct answer is A: Hypertension. Epoetin alfa can lead to hypertension as an adverse effect because it stimulates increased red blood cell production. This can result in elevated blood pressure levels, requiring careful monitoring by the nurse to prevent complications. Choice B, hypotension, is incorrect because epoetin alfa is more likely to cause hypertension rather than hypotension. Choice C, hyperglycemia, and Choice D, tachycardia, are also incorrect as they are not commonly associated with the use of epoetin alfa.
2. When administering medications to a group of clients, which client should the nurse closely monitor for the development of acute kidney injury (AKI)?
- A. Lorazepam
- B. Sucralfate
- C. Digoxin
- D. Vancomycin
Correct answer: D
Rationale: Vancomycin is known to be nephrotoxic, which means it can cause damage to the kidneys. Therefore, clients receiving Vancomycin should be closely monitored for signs and symptoms of acute kidney injury (AKI) to ensure early detection and intervention if necessary. Lorazepam, Sucralfate, and Digoxin do not typically cause acute kidney injury, so they are not the priority for monitoring in this scenario.
3. A client with anxiety is prescribed alprazolam. What instruction should the nurse include in the client's teaching plan?
- A. Take this medication with food.
- B. Avoid activities that require alertness.
- C. Do not stop taking this medication abruptly.
- D. This medication may cause drowsiness.
Correct answer: C
Rationale: The correct answer is C: 'Do not stop taking this medication abruptly.' Alprazolam should not be stopped suddenly as it can lead to withdrawal symptoms. It is important for clients to taper off the medication gradually under medical supervision to prevent adverse effects. Choices A, B, and D are incorrect. Choice A is irrelevant to alprazolam administration instructions. Choice B, 'Avoid activities that require alertness,' is not the priority teaching point for alprazolam. Choice D, 'This medication may cause drowsiness,' is a common side effect of alprazolam but not the most critical instruction to include in the teaching plan.
4. A client has a prescription for heparin 1,000 units IV STAT. Several pre-filled syringes of low molecular weight heparin are available in the client's medication drawer. Which action should the nurse implement?
- A. Dilute the available heparin in 250ml of normal saline solution prior to IV administration
- B. Advise the pharmacy on the need to deliver a vial of heparin to the nursing unit immediately
- C. Calculate and administer the equivalent dose of the available low molecular weight heparin
- D. Request a prescription to change the route of administration and use the available heparin
Correct answer: B
Rationale: In this scenario, the nurse should contact the pharmacy to obtain the correct heparin formulation as the prescription calls for heparin 1,000 units IV STAT. Low molecular weight heparin is not the same as unfractionated heparin, and therefore, the nurse should not administer the available low molecular weight heparin without first obtaining the correct medication. Diluting the available heparin, calculating an equivalent dose, or changing the route of administration would not address the discrepancy between the prescribed heparin and the available low molecular weight heparin.
5. A client with a history of atrial fibrillation is prescribed amiodarone. The nurse should monitor for which potential side effect?
- A. Pulmonary toxicity
- B. Liver toxicity
- C. Thyroid dysfunction
- D. Bradycardia
Correct answer: A
Rationale: Corrected Rationale: Amiodarone is known to cause pulmonary toxicity, which can manifest as respiratory symptoms. Monitoring for signs such as cough, dyspnea, or chest pain is essential to detect this serious side effect early and prevent further complications. Choices B, C, and D are incorrect because while amiodarone can also cause liver toxicity, thyroid dysfunction, and bradycardia, pulmonary toxicity is the most serious side effect that requires immediate attention due to its potential life-threatening consequences.
