LPN Pharmacology Assessment A

1. A client with atrial fibrillation is receiving warfarin (Coumadin). The nurse should monitor which laboratory test to determine the effectiveness of the therapy?

Correct answer: A

Rationale: To monitor the effectiveness of warfarin therapy in a client with atrial fibrillation, the nurse should assess the Prothrombin time (PT) and international normalized ratio (INR) levels. These tests help determine the clotting ability of the blood and ensure that the client's anticoagulation levels are within the therapeutic range, reducing the risk of bleeding or clotting complications. Activated partial thromboplastin time (aPTT) (Choice B) is more commonly used to monitor heparin therapy. Complete blood count (CBC) (Choice C) provides information about the cellular components of blood but does not directly assess the effectiveness of warfarin therapy. Fibrinogen level (Choice D) is not typically used to monitor warfarin therapy; it reflects the level of fibrinogen in the blood, which is involved in the clotting process.

2. A client is admitted to the hospital with a diagnosis of myocardial infarction (MI). Which diagnostic test is most likely to be ordered to confirm this diagnosis?

Correct answer: B

Rationale: An Electrocardiogram (ECG) is the primary diagnostic tool used to confirm a myocardial infarction. An ECG provides immediate information on cardiac function and can show characteristic changes indicative of a myocardial infarction, such as ST-segment elevation or depression. An echocardiogram (Choice A) is useful for assessing heart structure and function but is not typically used as the primary test for confirming an acute myocardial infarction. Chest X-ray (Choice C) may show certain changes in heart size or pulmonary congestion but is not the primary diagnostic test for MI. A Complete Blood Count (CBC) (Choice D) provides information about the cellular components of blood and is not specific to confirming a myocardial infarction.

3. A client reports chest pain that is unrelieved by three doses of nitroglycerin taken 5 minutes apart. What is the nurse's next best action?

Correct answer: B

Rationale: In the scenario described, the client's chest pain persists despite three doses of nitroglycerin, indicating a potentially severe cardiac issue like a myocardial infarction. The priority for the nurse in this situation is to involve the healthcare provider promptly. Calling the healthcare provider immediately is essential to ensure timely evaluation and appropriate intervention for the client. Administering more nitroglycerin without further assessment or instructions may not be safe and could delay necessary treatments. Providing oxygen or changing the client's position may offer some comfort but does not address the underlying potentially life-threatening condition, making these options less appropriate as the immediate next best action.

4. The client is receiving anticoagulant therapy for atrial fibrillation. Which laboratory test should be monitored to determine the effectiveness of the therapy?

Correct answer: A

Rationale: Prothrombin time (PT) and international normalized ratio (INR) are essential laboratory tests to monitor the effectiveness of anticoagulant therapy in clients with atrial fibrillation. These tests help ensure that the client is within the therapeutic range and are commonly used to assess the clotting ability of the blood. Monitoring PT and INR levels allows healthcare providers to adjust anticoagulant dosages as needed to prevent complications such as bleeding or thrombosis. Activated partial thromboplastin time (aPTT) is more commonly used to monitor heparin therapy, not anticoagulant therapy for atrial fibrillation. Platelet count assesses the number of platelets in the blood and is not a direct indicator of anticoagulant therapy effectiveness. Erythrocyte sedimentation rate (ESR) is a nonspecific marker of inflammation and is not used to monitor anticoagulant therapy.

5. A client with heart failure is prescribed an angiotensin-converting enzyme (ACE) inhibitor. What instruction should the nurse reinforce to the client?

Correct answer: B

Rationale: The correct answer is B. A persistent dry cough is a common side effect of ACE inhibitors and should be reported to the healthcare provider. This symptom can indicate a potential issue with the medication that may require adjustment or discontinuation. Choices A, C, and D are incorrect. Taking the medication at bedtime or with meals is not a specific instruction for ACE inhibitors. Increasing potassium-rich foods in the diet is not directly related to ACE inhibitor therapy and may not be suitable for all patients.
