LPN Pharmacology Questions

Correct Answer: C

Rationale: Hypokalemia is a known side effect of furosemide, a loop diuretic. Furosemide causes increased excretion of potassium in the urine, leading to low potassium levels in the body which can result in serious complications such as cardiac dysrhythmias. Therefore, any signs or symptoms of hypokalemia should be promptly reported to the healthcare provider for appropriate management. Choices A, B, and D are incorrect because weight gain, dry cough, and increased appetite are not typically associated with furosemide use and are not concerning side effects that require immediate reporting to the provider.

Correct Answer: C

Rationale: The correct instruction for a client starting metformin is to increase fluid intake. This is crucial to prevent gastrointestinal discomfort, a common side effect of metformin. Adequate hydration helps reduce the risk of gastrointestinal upset and ensures the medication is well-tolerated. Option A is generally true for metformin but is not as essential as maintaining proper hydration. Option B is important but not directly related to starting metformin. Option D is incorrect as a metallic taste in the mouth is not typically associated with metformin.

Correct Answer: A

Rationale: The correct answer is A: Monitor for a dry cough. When a client is prescribed enalapril, it is important to monitor for a dry cough because it can be a side effect that indicates a potential issue like angioedema. This side effect needs close attention as it may require discontinuation of the medication to prevent further complications. Choices B, C, and D are incorrect because enalapril does not need to be taken at bedtime, does not interact with grapefruit juice, and can be taken without regard to meals.

Correct Answer: B

Rationale: The correct answer is B: Dry cough. A dry cough is a common side effect of enalapril that can indicate the development of angioedema or potentially life-threatening angioedema. An onset of dry cough should be reported to the provider promptly as it may require discontinuation of the medication to prevent further complications. Frequent urination, tremors, and dizziness are not typically associated with enalapril use and are less likely to be of immediate concern compared to a dry cough in this context.

Correct Answer: D

Rationale: The correct answer is D: Tardive dyskinesia. Tardive dyskinesia is a serious side effect associated with the long-term use of haloperidol. It is characterized by involuntary movements of the face, tongue, and extremities. Early detection is crucial as tardive dyskinesia may be irreversible and should be reported promptly to the healthcare provider for further evaluation and management. Choices A, B, and C are incorrect because weight gain, dry mouth, and tremors are common side effects of haloperidol but are not as concerning as tardive dyskinesia. While they should still be monitored and managed, tardive dyskinesia requires immediate attention due to its potentially irreversible nature.
