WGU D027 pathopharm Questions
and Answers (100% Pass)
Mechanism of Action for loop diuretics


✓ block water reasborption in the loop of Henle of nephron. Increases

urine output




Suffix for loop


✓ -emide

ex: furosemide




cautions in using loop diuretics


✓ decreased potassium, decreased BP, ototoxicity, nephrotoxicity

USE WITH CAUTION in those who have auditory/renal impairments




Suffix for Thiazide Diuretics


✓ -thiazide




MOA for thiazide diuretics




Master01 | October, 2024/2025 | Latest update

, 1 | P a g e | © copyright 2024/2025 | Grade A+

✓ blood water reabsorption in distal tube of nephron-- increases urine

output




adverse drug reactions for thiazide diuretics


✓ decreases potassium, increases uric acid, increases calcium

AVOID use in hx with gout, use cautiously with kidney disease




Contraindicator for thiazide diuretics


✓ those with sulfa allergies, contains sulfa group in molecular structure.

Also avoid in hx of gout due to increase of uric acid




Aldosterone antagonists MOA


✓ inhibits aldosterone which results in sodium loss in the nephron, water

follows and is excreted, potassium is retained (potassium sparing

diuretic)




example of an aldosterone antagonist


✓ Spironolactone




adverse drug reactions for aldosterone antagonists




Master01 | October, 2024/2025 | Latest update

, 1 | P a g e | © copyright 2024/2025 | Grade A+

✓ high potassium, androgen blocking (blocks testosterone and causes

estrogen effects)




beta blocker examples


✓ Propranolol (Inderal)

Metroprolol (Lopressor/Toprol XL)


Atenolol (Tenormin)


Carvedilol (Coreg)




MOA of beta blockers


✓ block adrenergic effects of Beta 1 and Beta 2 receptors (cause

cholinergic effects)

result in low HR and Low BP




Contraindicators for beta blockers


✓ chronic respiratory conditions (particularly for beta 2 blockers)

HR <60 bpm


disguises hypoglycemia symptoms




What does angiotensin 2 do?


Master01 | October, 2024/2025 | Latest update

, 1 | P a g e | © copyright 2024/2025 | Grade A+

✓ angiotensin II causes vasonconstriction and secretion of aldosterone,

which results in reabsorption of sodium/water in the nephrons




angiotensin 2 converting enzyme inhibitor (ACE inhibitor) suffix and MOA


✓ suffix: -pril example: lisinopril

MOA: inhibits ACE from converting angiotensin 1 to angiotensin 2, therefor

prevents water reabsorption


decreases cardiac workload


decreases BP




Adverse drug reactions for ACE inhibitors


✓ high potassium, angioedema, dry cough




Angiotensin Receptor Blocker (ARBs) suffix and MOA


✓ suffix: sartan example: losartan

MOA: prevent Angiotensin2 from binding to receptor sites, which then

prevents reabsorption of water and vasoconstriction


leads to lower BP




Adverse drug reactions of ARBS
