Question

the nurse is caring for a client with newly diagnosed pulmonary arterial hypertension (pah) who has a positive vasoreactivity test and no signs of right - sided heart failure. which medication should the nurse expect the provider to prescribe? sildenafl epoprostenol bosentan amlodipine

Explanation:

For a client with newly diagnosed PAH, positive vasoreactivity test, and no right - sided heart failure, calcium channel blockers like Amlodipine are considered first - line therapy. Sildenafil is a PDE5 inhibitor, epoprostenol is a prostacyclin analog, and bosentan is an endothelin receptor antagonist. These are used in different scenarios (e.g., when calcium channel blockers are not effective or in specific PAH subtypes), while Amlodipine is appropriate for this case with positive vasoreactivity.

Answer:

D. Amlodipine
