Correct & Verified
What is the primary mechanism of action of beta-blockers in treating hypertension?
✔✔Beta-blockers reduce blood pressure by blocking adrenergic receptors, decreasing heart rate
and cardiac output.
Why are ACE inhibitors preferred in patients with both hypertension and diabetes?
✔✔ACE inhibitors protect kidney function and reduce proteinuria, making them beneficial for
diabetic patients with hypertension.
How do calcium channel blockers help in managing angina?
✔✔Calcium channel blockers relax coronary arteries and reduce myocardial oxygen demand by
decreasing heart rate and contractility.
What is a critical nursing consideration when administering nitroglycerin sublingually?
✔✔Ensure the patient is sitting or lying down to prevent hypotension and check for expiration
dates, as nitroglycerin loses potency quickly.
1
, Why must potassium levels be monitored in patients taking loop diuretics?
✔✔Loop diuretics cause significant potassium loss, increasing the risk of hypokalemia and
arrhythmias.
What is the key difference between heparin and warfarin in terms of monitoring?
✔✔Heparin requires aPTT monitoring, while warfarin requires INR monitoring due to their
different mechanisms of action.
How do statins contribute to cardiovascular health beyond lowering cholesterol?
✔✔Statins stabilize atherosclerotic plaques and reduce inflammation in blood vessels,
decreasing the risk of rupture.
What is the most serious adverse effect of thrombolytic therapy?
✔✔The most serious risk is severe bleeding, including intracranial hemorrhage, due to systemic
clot breakdown.
Why should NSAIDs be avoided in patients taking anticoagulants?
