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. The client is scheduled to undergo a treadmill stress test. Which instruction should the client be reinforced with?

Correct answer: B

Rationale: The correct answer is B: 'Wear comfortable shoes and clothing.' Wearing comfortable shoes and clothing is crucial for the client undergoing a treadmill stress test to ensure they can complete the test without discomfort. The right attire will help the client move freely and reduce the risk of any hindrance during the test, which requires physical activity. Choices A, C, and D are incorrect. A light meal before the test may be recommended, but it's not as crucial as wearing suitable attire. Avoiding physical activity the morning of the test is not necessary as the test requires physical activity. Taking prescribed medications right before the test instructions should be followed as per the healthcare provider's advice and not as a general rule for all clients undergoing the test.

3. An 81-year-old male client has emphysema. He lives at home with his cat and manages self-care with no difficulty. When making a home visit, the nurse notices that this client's tongue is somewhat cracked, and his eyeballs appear sunken into his head. Which nursing intervention is indicated?

Correct answer: A

Rationale: The client's cracked tongue and sunken eyes indicate dehydration. Therefore, the priority nursing intervention is to help the client determine ways to increase his fluid intake. Dehydration can exacerbate the client's emphysema symptoms and lead to further complications. Monitoring and addressing the client's fluid intake is crucial for maintaining his health and well-being. Options B, C, and D are not the immediate priorities in this situation. While an eye examination, oxygen use, and sensitivity tests are relevant aspects of care, addressing dehydration through increased fluid intake takes precedence in this scenario.

4. An ambulatory clinic nurse is interviewing a client who is complaining of flu-like symptoms. The client suddenly develops chest pain. Which question best assists the nurse in discriminating pain caused by a non-cardiac problem?

Correct answer: C

Rationale: The correct answer is C. Pain that worsens with breathing in can indicate pleuritic chest pain, which is non-cardiac in nature. This specific question helps in differentiating non-cardiac causes from cardiac causes of chest pain, as cardiac pain typically does not worsen with breathing. Choices A, B, and D are less specific in discriminating between cardiac and non-cardiac chest pain.

5. A client has a new prescription for transdermal nitroglycerin patches. Which of the following instructions should be included for proper use?

Correct answer: B

Rationale: Placing the nitroglycerin patch on an area of skin away from skin folds and joints is crucial to ensure optimal absorption and effectiveness of the medication. Placing the patch on skin folds or joints can interfere with absorption, potentially reducing the patch's efficacy. Therefore, it is essential to follow this instruction to maximize the therapeutic benefits of the nitroglycerin patches. The other options are incorrect because applying the patch to the same site each day can lead to skin irritation, keeping the patch on 24 hours per day may not be necessary depending on the specific patch instructions, and replacing the patch every 72 hours is not the standard frequency for nitroglycerin patches.
