LPN Pharmacology Assessment A

Correct Answer: A

Rationale: The correct instruction to prevent bleeding complications in a client on anticoagulant therapy is to use a soft-bristle toothbrush and electric razor. These implements help reduce the risk of bleeding by being gentle on the skin and reducing the chances of cuts or abrasions that could lead to bleeding in individuals on anticoagulants.

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.

Correct Answer: A

Rationale: The correct instruction is to take aspirin with food to prevent gastrointestinal upset. Aspirin can irritate the stomach lining, leading to potential gastrointestinal issues. Taking it with food helps reduce this risk by providing a protective layer in the stomach. This is a common recommendation to minimize the risk of gastrointestinal side effects when taking aspirin.

Correct Answer: B

Rationale: Metoprolol is a beta-blocker commonly used in heart failure to reduce blood pressure. One of the common side effects of metoprolol is hypotension, which can lead to dizziness, lightheadedness, and even fainting. Therefore, monitoring for hypotension is essential to prevent adverse effects and ensure patient safety.

Correct Answer: B

Rationale: Bradycardia is a common sign of digoxin toxicity. Digoxin can cause disturbances in the heart's electrical conduction system, leading to a slower heart rate. Therefore, the nurse should closely monitor the client's heart rate for signs of bradycardia, which could indicate digoxin toxicity.
