LPN Pharmacology Practice Questions

1. The client with atrial fibrillation is receiving warfarin (Coumadin). Which laboratory test should be monitored to determine the effectiveness of the therapy?

Correct answer: A

Rationale: Monitoring Prothrombin time (PT) and international normalized ratio (INR) is crucial when a client is on warfarin therapy. These tests assess the clotting ability of the blood and help determine the appropriate dosage of warfarin to prevent complications such as bleeding or clotting events. PT and INR values within the therapeutic range indicate the effectiveness of warfarin in managing atrial fibrillation. Choice B, activated partial thromboplastin time (aPTT), is not typically used to monitor warfarin therapy; it is more commonly used to assess the effectiveness of heparin therapy. Choice C, complete blood count (CBC), does not directly assess the anticoagulant effect of warfarin. Choice D, fibrinogen level, is not a primary test for monitoring warfarin therapy; it is more relevant in assessing conditions like disseminated intravascular coagulation.

2. A client who had a myocardial infarction (MI) two days ago reports chest pain radiating to the left arm. What should the nurse do immediately?

Correct answer: B

Rationale: Obtaining an ECG is crucial in this situation because it helps in assessing for potential complications, such as a recurrent MI or ongoing ischemia. This diagnostic test provides valuable information to guide further interventions and treatment. Administering morphine, oxygen, or nitroglycerin may be necessary but obtaining an ECG takes precedence to evaluate the cardiac status and determine the appropriate course of action. Administering morphine without assessing the current cardiac status through an ECG can mask important diagnostic clues. Applying oxygen and administering nitroglycerin are supportive measures that can follow the ECG to address potential hypoxia and ischemic pain relief, respectively.

3. The client is being ambulated due to activity intolerance caused by bacterial endocarditis. How can the nurse determine that the client is best tolerating ambulation?

Correct answer: D

Rationale: A slight increase in blood pressure without significant symptoms indicates that the client is tolerating the activity. In this scenario, a mild increase in blood pressure without other symptoms is a positive sign of tolerance to ambulation despite the underlying condition of bacterial endocarditis. Choices A, B, and C are not the best indicators of tolerance to ambulation in this case. Mild dyspnea after walking a short distance, minimal chest pain, and an increase in pulse rate are common signs that the activity might not be well-tolerated by the client with a history of bacterial endocarditis.

4. The healthcare provider is monitoring a client with left-sided heart failure. Which assessment finding indicates that the client's condition is worsening?

Correct answer: C

Rationale: Bibasilar crackles are abnormal lung sounds that indicate fluid accumulation in the lungs, a sign that left-sided heart failure is worsening. This finding suggests that the client's condition is deteriorating and requires prompt intervention to prevent further complications. Clear lung sounds (Choice A) are normal and would not indicate worsening heart failure. Increased peripheral pulses (Choice B) may be seen in conditions like anxiety or exercise, but not specifically in worsening left-sided heart failure. Improved activity tolerance (Choice D) would be a positive sign, not an indicator of worsening heart failure.

5. A client receives discharge teaching for a new prescription of lithium. Which instruction should be included?

Correct answer: B

Rationale: The correct instruction to include when a client receives discharge teaching for a new prescription of lithium is to increase their intake of sodium. Lithium can lead to decreased sodium levels, putting the individual at risk of developing hyponatremia. By increasing sodium intake, the client can counteract this risk, maintain a proper sodium balance, and prevent complications. Choices A, C, and D are incorrect because taking lithium with food, monitoring for signs of hypercalcemia, and avoiding dairy products are not directly related to managing the side effects or risks associated with lithium therapy.
