LPN Pharmacology Assessment A

1. 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.

2. When preparing to administer medication to a client, what action should the nurse take first?

Correct answer: A

Rationale: Verifying the client's identity is the initial and most critical step in medication administration. It is crucial to confirm that the right medication is being given to the correct patient. Checking the client's identity helps prevent medication errors and ensures patient safety. Checking the medication expiration date (choice B) is important but should come after verifying the client's identity. Reviewing the client's medical history (choice C) is valuable but not the first step in medication administration. Obtaining the client's vital signs (choice D) is essential in some situations but is usually not the first action needed before administering medication.

3. The client with chronic stable angina is prescribed a beta blocker. The nurse is reinforcing instructions. What instruction should the nurse include?

Correct answer: B

Rationale: The correct instruction for the nurse to include is to advise the client to report a pulse rate below 60 beats per minute. Beta blockers are known to lower heart rate, and a pulse rate below 60 beats per minute may indicate bradycardia, a condition that requires medical attention. Option A, 'Take the medication with a meal,' is incorrect because beta blockers don't necessarily need to be taken with food. Option C, 'Discontinue the medication if dizziness occurs,' is incorrect because abrupt cessation of beta blockers can lead to rebound hypertension and other adverse effects. Option D, 'Avoid drinking grapefruit juice,' is unrelated to beta blockers' mechanism of action or side effects.

4. A client has a history of left-sided heart failure. The nurse should look for the presence of which finding to determine whether the problem is currently active?

Correct answer: B

Rationale: When assessing a client with a history of left-sided heart failure, the presence of bilateral lung crackles is a key finding to determine if the condition is currently active. Crackles in the lungs indicate fluid accumulation, a common sign of left-sided heart failure due to pulmonary congestion. Choices A, C, and D are incorrect because ascites, jugular vein distention, and pedal edema are more commonly associated with right-sided heart failure.

5. The patient with a history of myocardial infarction (MI) is prescribed aspirin. What instruction should the nurse include in the discharge teaching?

Correct answer: A

Rationale: Taking aspirin with food is recommended to prevent gastrointestinal irritation and upset, which are common side effects of aspirin. It helps protect the stomach lining and reduce the risk of developing ulcers. This instruction is crucial in promoting medication adherence and minimizing discomfort for the patient. Choices B, C, and D are incorrect because discontinuing aspirin without consulting a healthcare provider, taking it at bedtime, or avoiding it if taking other NSAIDs can have negative consequences on the patient's health and treatment plan.
