LPN Pharmacology Assessment A

Correct Answer: B

Rationale: Before administering enalapril, an antihypertensive medication, the nurse should prioritize checking the client's blood pressure. Monitoring blood pressure helps ensure it is at an acceptable level before giving the medication, as enalapril can further lower blood pressure. This assessment is crucial in preventing potential hypotensive episodes and adverse effects associated with excessive blood pressure reduction.

Correct Answer: C

Rationale: When a client is receiving furosemide, which is a loop diuretic, it can lead to potassium loss. Therefore, monitoring the serum potassium levels is crucial to prevent life-threatening complications such as cardiac arrhythmias.

Correct Answer: C

Rationale: When a client with heart failure is prescribed furosemide, the nurse should monitor for hypokalemia. Furosemide is a loop diuretic that can lead to potassium loss, which increases the risk of hypokalemia. Hypokalemia can have serious implications such as cardiac dysrhythmias. Therefore, it is essential to closely monitor the client's serum potassium levels while on furosemide to prevent complications.

Correct Answer: C

Rationale: Nausea is an early sign of theophylline toxicity. The nurse should closely monitor the client for this symptom as it can progress to more severe toxicity. Nausea can be a warning sign to prevent further complications and adjust the dosage as necessary.

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.
