Rationale: The correct administration of Nitroglycerin sublingual tablets involves taking one tablet at the onset of chest pain and repeating every 5 minutes for up to three doses. If the pain persists after three doses, emergency medical services should be contacted for further evaluation and management.

Correct Answer: A

Rationale: Losartan, an angiotensin II receptor blocker (ARB), can cause hyperkalemia by affecting the renin-angiotensin-aldosterone system. Monitoring serum potassium levels is crucial to detect and manage any potential hyperkalemia, which can lead to serious cardiac arrhythmias.

Correct Answer: D

Rationale: An adverse effect of prochlorperazine is acute dystonia, which is evidenced by spasms of the muscles in the face, neck, and tongue. Diphenhydramine is used to suppress extrapyramidal effects of prochlorperazine, making it the most appropriate choice to address the client's spasms.

Correct Answer: D

Rationale: Oxybutynin is an anticholinergic medication that can increase intraocular pressure. It is contraindicated in clients with glaucoma due to the potential to worsen the condition by further elevating intraocular pressure, leading to harm. Therefore, choosing option D, Glaucoma, as the correct answer is essential for the client's safety and to prevent exacerbation of their eye condition.

Correct Answer: C

Rationale: The nurse should monitor the aPTT (activated partial thromboplastin time) when caring for a client receiving Heparin therapy. The aPTT reflects the intrinsic pathway of the clotting cascade and is used to monitor the effectiveness of heparin, which primarily affects this pathway by potentiating antithrombin III. Monitoring the aPTT helps ensure that the client's blood is within the therapeutic range to prevent thrombus formation.
