LPN Pharmacology Assessment A

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: B

Rationale: Nitroglycerin is a rapid-acting medication used to relieve angina pain by dilating blood vessels. The correct administration is to take one tablet every 5 minutes as needed, up to three doses. If chest pain persists after three doses, the client should seek emergency medical attention as it can indicate a more serious cardiac issue.

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: 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.

Correct Answer: B

Rationale: Thrombolytic therapy is associated with an increased risk of bleeding due to its mechanism of action in dissolving blood clots. Therefore, the nurse should closely monitor the client for any signs of hemorrhage, such as unexplained bruising, bleeding gums, or blood in the urine or stools.
