Rationale: The patient was recently diagnosed with hypertension and diastolic dysfunction. The supine blood pressure was 166/94 mm Hg and standing blood pressure was 140/83 mm Hg. Given these values, the patient is likely taking Hydrochlorothiazide, which is a diuretic commonly used to treat hypertension by reducing fluid volume and lowering blood pressure. This drug would be an appropriate choice for a patient with these blood pressure readings and hypertension diagnosis.

Correct Answer: C

Rationale: The most likely trigger for the patient's present chest pain is the abrupt withdrawal from nitrate therapy. Nitrates are commonly used in the treatment of angina to help relax and widen blood vessels, improving blood flow to the heart. Abruptly stopping nitrate therapy can lead to rebound symptoms, including chest pain, due to the body's dependence on the medication for vasodilation. This withdrawal can cause a sudden decrease in nitric oxide levels, leading to vasoconstriction and potentially triggering angina symptoms.
