LPN Pharmacology Practice Test

Correct Answer: A

Rationale: The correct answer is A: 'You should have your white blood cell count checked regularly.' Clozapine can lead to agranulocytosis, a serious condition characterized by a low white blood cell count. Regular monitoring of the white blood cell count is crucial to detect this adverse effect early and prevent serious complications. Choices B, C, and D are incorrect because taking clozapine on an empty stomach, avoiding foods high in tyramine, or avoiding taking the medication with milk are not specific instructions related to the potential adverse effect of agranulocytosis associated with clozapine.

Correct Answer: D

Rationale: Instructing the client to take nitroglycerin at the first sign of chest pain is crucial for immediate relief of angina symptoms. Nitroglycerin is a fast-acting medication that helps dilate blood vessels, improving blood flow to the heart muscle. Therefore, prompt administration at the onset of chest pain is essential to alleviate anginal episodes effectively. Choices A, B, and C are incorrect because storing the medication properly, taking it as directed, or before meals are not specific instructions for managing acute anginal episodes, which require immediate action for symptom relief.

Correct Answer: B

Rationale: The priority finding for the nurse to report to the provider is B: Fever. Fever can be an indication of agranulocytosis, a potentially life-threatening condition associated with clozapine. Agranulocytosis is characterized by a significant decrease in white blood cells, making the client susceptible to severe infections. Prompt reporting of fever is crucial to prevent serious complications. Elevated blood pressure (Choice A), weight gain (Choice C), and dry mouth (Choice D) are important to monitor but are not as immediately concerning as fever, which could indicate a severe adverse reaction requiring urgent medical attention.

Correct Answer: D

Rationale: The correct answer is D: Persistent cough. Enalapril, an ACE inhibitor, is known to commonly cause a persistent cough as an adverse effect due to its effect on bradykinin levels. Clients should be instructed to monitor for a persistent cough and report it promptly to their healthcare provider for further evaluation and possible medication adjustment. Choices A, B, and C are incorrect as they are not commonly associated with enalapril use and are not typical adverse effects of ACE inhibitors.

Correct Answer: C

Rationale: When administering controlled substances, it is crucial to have a second nurse witness the disposal of the medication. This measure ensures proper handling, reduces the risk of diversion, and promotes compliance with regulations regarding controlled substances. Having a second nurse witness the disposal is a safeguard to maintain accountability and prevent any potential misuse or errors during the disposal process. Checking the client's identification bracelet and allergy status are important steps in medication administration but are not specifically required for controlled substances. Documenting the administration in the client's medical record is essential but does not specifically relate to the disposal of controlled substances.
