LPN Pharmacology Assessment A

Correct Answer: A

Rationale: Taking digoxin at the same time each day is essential to maintain a consistent blood level of the medication. This consistency helps optimize the therapeutic effects of digoxin in managing chronic heart failure. Deviating from the scheduled time could lead to fluctuations in drug levels, affecting its effectiveness and potentially causing harm.

Correct Answer: C

Rationale: Cigarette smoking is a modifiable risk factor for coronary artery disease (CAD) because it can be changed or controlled to reduce the risk of developing CAD. Family history, age, and gender are non-modifiable risk factors, meaning they cannot be changed. By emphasizing the importance of quitting smoking, the nurse can help the client reduce their risk of CAD and improve their overall cardiovascular health.

Correct Answer: B

Rationale: In a client with pulmonary edema, placing them in a high Fowler's position is the priority intervention. This position helps to improve ventilation and oxygenation by decreasing venous return, reducing the workload on the heart, and facilitating fluid redistribution from the lungs. It is crucial to optimize respiratory function and oxygenation before considering other interventions like administering medications, preparing for intubation, or inserting a urinary catheter.

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: C

Rationale: Atenolol is a beta-blocker that commonly causes hypotension by lowering blood pressure. Therefore, monitoring for hypotension is crucial to prevent potential complications in the client receiving this medication.
