HESI Practice Test Pharmacology
1. A client with a history of stroke is prescribed clopidogrel. The nurse should monitor for which potential side effect?
- A. Bleeding
- B. Weight gain
- C. Nausea
- D. Headache
Correct answer: A
Rationale: When a client with a history of stroke is prescribed clopidogrel, the nurse should monitor for potential side effects, especially bleeding. Clopidogrel is an antiplatelet medication that works by preventing blood clots. One of the major risks associated with clopidogrel is an increased tendency to bleed. Therefore, monitoring for signs of bleeding, such as easy bruising, blood in stool or urine, or prolonged bleeding from minor cuts, is crucial to ensure patient safety and early intervention if needed.
2. A client is prescribed ondansetron for nausea and vomiting. The nurse should monitor the client for which potential adverse effect?
- A. Headache
- B. Diarrhea
- C. Constipation
- D. Increased appetite
Correct answer: C
Rationale: The correct answer is C: Constipation. Ondansetron is known to cause constipation as a potential adverse effect. It is important for the nurse to monitor the client for constipation while on this medication to address any issues promptly. Choices A, B, and D are incorrect because headache, diarrhea, and increased appetite are not common adverse effects associated with ondansetron.
3. A client who is recovering from an appendectomy is receiving narcotics. Earlier, the nurse witnessed the client's family pushing the pain pump. What should the nurse implement?
- A. Check the client's level of consciousness
- B. Instruct the family not to push the button
- C. Stop the client's basal infusion
- D. Administer a narcotic reversal medication
Correct answer: B
Rationale: Instructing the family not to push the button is necessary to prevent the client from receiving an excessive amount of narcotics, ensuring the safe and appropriate use of the pain pump. Checking the client's level of consciousness may not address the issue of family members pushing the button. Stopping the client's basal infusion is not indicated unless there are specific medical reasons for doing so. Administering a narcotic reversal medication is not necessary at this point as the issue lies with inappropriate use rather than an overdose.
4. A client with chronic heart failure is prescribed spironolactone. The nurse should monitor for which potential side effect?
- A. Hyperkalemia
- B. Hypokalemia
- C. Hypernatremia
- D. Hyponatremia
Correct answer: A
Rationale: The correct answer is A: Hyperkalemia. Spironolactone is a potassium-sparing diuretic that can lead to an excess of potassium in the body, resulting in hyperkalemia. This side effect is important to monitor in clients taking spironolactone, especially those with chronic heart failure, as hyperkalemia can lead to serious cardiac complications.
5. A client with a diagnosis of generalized anxiety disorder is prescribed lorazepam. The client should be informed that this medication may have which potential side effect?
- A. Drowsiness
- B. Dry mouth
- C. Nausea
- D. Headache
Correct answer: A
Rationale: The correct answer is A: Drowsiness. Lorazepam, a medication commonly used to treat anxiety disorders, can lead to drowsiness as a common side effect. It is important for clients to be aware of this potential effect, and they should be advised to avoid activities like driving until they understand how the medication affects them. Dry mouth, nausea, and headache are possible side effects of other medications but are less commonly associated with lorazepam.
