Galen Pharmacology Exam 3 Questions With All Correct Answers Verified Answers 2025 Marking Scheme New Update Furosemide (Lasix) - Answer- Potassium Wasting Loop Diuretic used for Edema. Inhibition of sodium and water reabsorption from the Loop of Henle and distal renal tubes. K, Mg, Ca may also be excreted. Adverse Reactions: orthostatic hypotension, hyperglycemia, K+,Na+, Mag+ deficit Spironolactone (Aldactone) - Answer- Potassium Sparing Diuretic used for Edema Acts on distal renal tubes to promote sodium and water excretion and potassium retention. Adverse Reactions: severe hyperkalemia, thrombocytopenia Hydrochlorothiazide (Microzide) - Answer- Potassium Wasting Thiazide Diuretic used for increasing urine output and edema Action is on the renal distule tubes, promoting Na, K, and water excretion and decreasing preload and cardiac output; also decreases edema; acts on arterioles and causes vasodilation, thus decreasing blood pressure Adverse Reactions: orthostatic hypotension, hyponatremia, hypokalemia, hypercalcemia Mannitol (Osmitrol) - Answer- Potassium Wasting Osmotic Diuretic used for IOP ICP and edema Increases osmolality (concentration) and sodium reabsoprtion in the proximal tubue and Loop of Henle. Adverse Reactions: pulmonary edema, tachycardia from rapid shift of fluids Mannitol can crystallize so it must be warmed to dissolve crystals before administration Prazosin (Minipress) - Answer- Potassium Wasting Alpha Adrenergic Blocker used to control hypertension Dilates peripheral blood vessels by blocking alpha adrenergic receptors. Adverse Effects: orthostatic hypotension, palpitation, tachycardia Nifedipine (Procardia) - Answer- Calcium Channel Blocker used for hypertension and angina Blocks calcium channel in the VSM (vascular smooth muscle), promoting vasodilation. Adverse Reactions: bradycardia and AV block Metoprolol (Lopressor) - Answer- Cardiac Selective Beta Blocker used for hypertension Promotes blood pressure reduction via a beta1-blocking effect. Slows heart rate down which decreases blood pressure. Adverse Reactions: Bradycardia, thrombocytopenia, Life Threatening: Bronchospasm Propranolol (Hemangeol) - Answer- Antagonist Adrenergic Blocker/Non-Selective Beta Blocker used for hypertension, AMI, angina Heartrate slows and bronchoconstriction occurs. Adverse Reactions: Bradycardia, hyperkalemia, seizures, bronchospasm Lisinopril (Zestril) - Answer- Angiotensin Converting Enzyme (ACE) Inhibitor used for hypertension Vasodilation which lowers resistance which makes it easier for heart to pump. Adverse Reactions: hyperkalemia, angioedema, laryngeal edema Valsartan (Diovan) - Answer- Angiotensin II Receptor Blockers (ARBs) used for hypertension and heart failure Potent vasodilator that inhibits binding of angiotensin II. Adverse Reactions: Orthostatic hypotension, hyperkalemia Life Threatening: Renal Dysfunction Isoniazid (Hydra) - Answer- Antitubercular used to treat TB and as a prophylactic for TB Bactericidal or bacteriostatic inhibits bacterial cell-wall synthesis. Adverse Reactions: peripheral neuropathy, vitamin B6 deficiency, hyperglycemia, hepatoxicity, seizure Rifampin - Answer- Antitubercular used in combination to treat TB Bactericidal or bacteriostatic. Adverse Reactions: Hepatic toxicity

Hydrochlorothiazide (Microzide) - Answer- Potassium Wasting Thiazide Diuretic used
for increasing urine output and edema

Action is on the renal distule tubes, promoting Na, K, and water excretion and
decreasing preload and cardiac output; also decreases edema; acts on arterioles and
causes vasodilation, thus decreasing blood pressure

Adverse Reactions: orthostatic hypotension, hyponatremia, hypokalemia,
hypercalcemia
