Question 6

A patient with a history of myocardial infarction is prescribed aspirin. What is the primary mechanism by which aspirin reduces the risk of another heart attack?

Question 7

Which of the following blood pressure readings would be classified as 'Stage 2 Hypertension' according to the provided chart?

Accepted Answer

Question 11

A 70-year-old patient is being treated for hypertension with a thiazide diuretic. Which laboratory value should be closely monitored due to the risk of depletion?

Accepted Answer

Serum potassium

Question 12

Which of the following is a modifiable risk factor for atherosclerosis?

Accepted Answer

Question 13

A patient is prescribed nitroglycerin for angina. Which of the following instructions is most important to prevent a dangerous drug interaction?

Accepted Answer

Question 14

Which of the following best explains why hypertension increases the risk of atherosclerosis?

Accepted Answer

Question 15

A patient with a history of heart failure is prescribed spironolactone. What is the primary action of this medication?

Accepted Answer

It is a potassium-sparing diuretic that acts in the distal tubule.

Question 16

A 60-year-old patient is prescribed omega-3 fatty acids for hypertriglyceridemia. What is the primary effect of omega-3 fatty acids on lipid metabolism?
