Paper For Above instruction

Hypertension remains a prevalent chronic condition among nursing home residents, requiring careful management to prevent cardiovascular complications (Zhou et al., 2021). As advanced practice nurses update care plans, understanding the pharmacologic actions of antihypertensive medications and patient education is crucial for optimal outcomes. This paper provides a comprehensive overview of the therapeutic actions of key antihypertensive drug classes—diuretics, angiotensin-converting enzyme (ACE) inhibitors, angiotensin receptor blockers (ARBs), calcium channel blockers (CCBs), and sympathetic nervous system drugs—and highlights essential teaching points for patients receiving these medications.

Therapeutic Actions of Antihypertensive Drugs

Diuretics are among the oldest and most commonly used antihypertensive agents. They primarily reduce blood pressure by decreasing plasma volume through promoting sodium and water excretion in the kidneys (Jensen et al., 2020). Thiazide diuretics, such as hydrochlorothiazide, inhibit sodium reabsorption in the distal tubules, leading to decreased blood volume and peripheral vascular resistance. Loop diuretics, like furosemide, act on the loop of Henle, producing a potent diuretic effect suitable for volume overload states. Potassium-sparing diuretics, such as spironolactone, antagonize aldosterone, helping to prevent hypokalemia and providing additional antihypertensive effects.

ACE inhibitors, such as enalapril and lisinopril, block the conversion of angiotensin I to angiotensin II, a potent vasoconstrictor. This results in vasodilation, decreased aldosterone secretion (reducing sodium and water retention), and ultimately lowering blood pressure (Sharma et al., 2022). ARBs, including losartan and valsartan, inhibit angiotensin II from binding to its receptors, producing similar vasodilatory effects without affecting bradykinin levels, thereby reducing cough and angioedema associated with ACE inhibitors.

Calcium channel blockers exert their antihypertensive effect by inhibiting the influx of calcium ions into vascular smooth muscle and cardiac cells, leading to vasodilation and decreased myocardial contractility (Ahmed et al., 2021). Dihydropyridines, like amlodipine, primarily affect vascular smooth muscle, while non-dihydropyridines, such as diltiazem and verapamil, also influence cardiac conduction and contractility. They are especially useful in controlling systolic hypertension and exert anti-anginal effects.

Sympathetic nervous system drugs, including beta-blockers like metoprolol and atenolol, reduce blood pressure by decreasing cardiac output and suppressing renin release from the kidneys (Patel & Shah, 2019). Central adrenergic inhibitors, such as clonidine, act on the central nervous system to reduce sympathetic outflow, leading to vasodilation and decreased heart rate. Peripheral adrenergic antagonists affect alpha receptors to cause vasodilation and reduce vascular resistance.

Key Teaching Points for Patients on Antihypertensive Drugs

Effective patient education is essential to promote medication adherence, prevent adverse effects, and recognize warning signs of complications. Patients should understand that antihypertensive medications often require long-term use, and effects may not be immediately apparent (Miller et al., 2020). The importance of consistent medication intake, even when asymptomatic, must be emphasized.

Patients should be instructed on potential side effects, such as orthostatic hypotension, dizziness, fatigue, or cough. For example, ACE inhibitors may cause a dry cough and angioedema; patients should seek prompt medical attention if these occur. Diuretics can lead to electrolyte imbalances, dehydration, and increased urination. Regular monitoring of blood pressure and laboratory tests for renal function and electrolytes are imperative during therapy.

Additionally, lifestyle modifications—including low-sodium diet, weight management, regular physical activity, and moderation of alcohol intake—should complement pharmacologic treatment (Williams et al., 2021). Patients should be advised to monitor their blood pressure at home and report any significant changes or adverse symptoms to their healthcare provider. Educating patients about the importance of adherence, understanding their specific medication regimen, and recognizing adverse effects can greatly enhance treatment success and reduce risks of hypertensive complications.
