HESI Practice Test Pharmacology
1. A client with a history of atrial fibrillation is prescribed verapamil. The nurse should monitor for which potential side effect?
- A. Constipation
- B. Diarrhea
- C. Headache
- D. Hypotension
Correct answer: A
Rationale: Verapamil, a calcium channel blocker, can commonly cause constipation due to its effects on smooth muscle relaxation in the gastrointestinal tract. Therefore, monitoring for constipation is important when a client is prescribed verapamil.
2. In the immediate postoperative period, a client is prescribed morphine via a patient-controlled analgesia (PCA) pump. Which finding should the PN consider the highest priority in this client?
- A. Monitoring the expiration date of the PCA morphine
- B. Assessing the rate and depth of the client's respirations
- C. Reviewing the type of anesthesia used during the surgery
- D. Observing the client's signs of disorientation
Correct answer: B
Rationale: The highest priority for the PN is to assess the rate and depth of the client's respirations when a client is receiving morphine via a PCA pump. Respiratory depression is a life-threatening side effect of intravenous morphine administration. If the client's respiratory rate falls below 10 breaths/min, the PCA pump should be stopped, and the healthcare provider must be notified immediately to prevent further complications. Monitoring the expiration date of the PCA morphine is important but not the highest priority compared to assessing respiratory status. Reviewing the type of anesthesia used during the surgery is not directly related to the immediate management of the client receiving morphine via PCA. Observing signs of disorientation is also important but not as critical as assessing respirations for potential respiratory depression.
3. A client with a history of hypertension is prescribed hydrochlorothiazide. The practical nurse should monitor the client for which potential adverse effect?
- A. Hyperkalemia
- B. Hypokalemia
- C. Hypernatremia
- D. Hyponatremia
Correct answer: B
Rationale: Corrected Rationale: Hydrochlorothiazide is a diuretic that can lead to potassium loss, resulting in hypokalemia. Monitoring for hypokalemia is essential because it can cause various complications such as cardiac dysrhythmias. Therefore, the practical nurse should closely watch for signs and symptoms of low potassium levels in clients taking hydrochlorothiazide. Incorrect Rationale for Other Choices: A. Hyperkalemia is not typically associated with hydrochlorothiazide use; instead, it is more commonly linked to medications like ACE inhibitors or potassium-sparing diuretics. C. Hypernatremia is unlikely with hydrochlorothiazide use as it tends to cause sodium loss. D. Hyponatremia is more commonly associated with conditions where there is excessive water intake or syndrome of inappropriate antidiuretic hormone secretion (SIADH), rather than with hydrochlorothiazide use.
4. The healthcare professional is caring for a patient with a new order for an oral laxative. Which is a contraindication in administering an oral laxative?
- A. Cardiac problems
- B. Abdominal pain of unknown origin
- C. Several hemorrhoids
- D. Chronic constipation
Correct answer: B
Rationale: Administering an oral laxative to a patient with abdominal pain of unknown origin is contraindicated because it could be a sign of a more serious underlying condition that needs immediate medical evaluation. Giving a laxative in such a situation without proper diagnosis could potentially worsen the patient's condition or delay appropriate treatment. Choice A (Cardiac problems) is not a contraindication for an oral laxative unless the patient has a specific cardiac condition that interacts with the laxative. Choice C (Several hemorrhoids) and Choice D (Chronic constipation) are not contraindications for administering an oral laxative.
5. A client with a diagnosis of bipolar disorder is prescribed topiramate. The nurse should monitor for which potential adverse effect?
- A. Cognitive impairment
- B. Weight gain
- C. Liver toxicity
- D. Weight loss
Correct answer: A
Rationale: Correct. Topiramate is associated with cognitive impairment as an adverse effect. It is important for the nurse to monitor the client's cognitive function while on this medication to assess for any signs of cognitive decline or impairment. Choice B, weight gain, is incorrect as topiramate is actually associated with weight loss rather than weight gain. Choice C, liver toxicity, is also incorrect as topiramate is not known to cause liver toxicity. Choice D, weight loss, is not the correct answer as topiramate is not associated with weight gain.
