NURS 3335 EXAM 3 UPDATED
QUESTIONS AND CORRECT ANSWERS.
What is the suffix for loop diuretics like Furosemide? - ANS -ide
Why should Furosemide be given in the morning? - ANS To prevent nocturia (frequent
urination at night)
What can happen if Furosemide is infused too fast? - ANS Tinnitus and hypotension
What is the suffix for thiazide diuretics? - ANS -thiazide
Why is Hydrochlorothiazide not effective for immediate diuresis? - ANS It works more slowly
and is only effective if potassium is within normal range
What is the expected ICP range Mannitol helps manage? - ANS 5-15 mmHg
What is the expected IOP range Mannitol helps manage? - ANS 10-21 mmHg
What should the nurse monitor for with Mannitol use? - ANS Neuro and renal function, urine
output, and electrolyte imbalances

, What foods should be avoided with Spironolactone? - ANS Potassium-rich foods and salt
substitutes
What ECG changes can occur with hyperkalemia from Spironolactone? - ANS Peaked T-
waves, ST elevation
What is the normal serum potassium range? - ANS 3.5-5.0 mEq/L
How should oral potassium be taken? - ANS With food to reduce GI upset
What are signs of hyperkalemia? - ANS Muscle cramps, weakness, irregular heartbeat
What is the normal magnesium range? - ANS 1.5-2.5 mEq/L
What is the antidote for magnesium toxicity? - ANS Calcium gluconate
What conditions contraindicate magnesium use? - ANS Hypermagnesemia, heart block,
severe renal failure
What class of drug is Furosemide? - ANS Loop diuretic (Potassium-wasting)
What is the MOA of Furosemide? - ANS Inhibits Na, Cl, and H2O reabsorption in the
ascending loop of Henle, causing rapid diuresis and potassium loss
What are key side effects of Furosemide? - ANS Hypokalemia, hypotension, ototoxicity,
hyperglycemia, metabolic alkalosis
What are key nursing considerations for Furosemide? - ANS Give in the morning, monitor
electrolytes, infuse slowly (20 mg/min), encourage potassium-rich foods
