Question 1
A patient is brought to the emergency department with shortness of
breath, a respiratory rate of 30 breaths per minute, intercostal
retractions, and frothy, pink sputum. The nurse caring for this
patient will expect to administer which drug?
A. Hydrochlorothiazide (HydroDIURIL)
B. Mannitol (Osmitrol)
C. Spironolactone (Aldactone)
D. Furosemide (Lasix) ← CORRECT ANSWER
Rationale: Furosemide is a potent loop diuretic used when rapid
mobilization of fluids is needed. The patient's symptoms indicate
pulmonary edema from congestive heart failure requiring immediate
diuresis. Hydrochlorothiazide is a thiazide diuretic with less potent
effects and slower onset, not appropriate for acute pulmonary edema.
Mannitol is an osmotic diuretic used for increased intracranial
pressure, not pulmonary edema; it can actually worsen pulmonary
congestion. Spironolactone is a potassium-sparing diuretic with weak
,diuretic effects and slow onset, not suitable for acute pulmonary
edema management.
Question 2
A patient who is taking digoxin is admitted for congestive heart
failure. The prescriber orders furosemide. The nurse notes an
irregular heart rate of 86 bpm, respiratory rate of 22, BP 130/82, and
crackles in both lungs. Which laboratory value causes the nurse the
most concern?
A. Blood glucose level of 120 mg/dL
B. Oxygen saturation of 90%
C. Sodium level of 140 mEq/L
D. Potassium level of 3.5 mEq/L ← CORRECT ANSWER
Rationale: Hypokalemia (3.5 mEq/L) increases the risk of digoxin
toxicity and fatal dysrhythmias. Furosemide causes potassium loss
through the distal nephron. Blood glucose of 120 mg/dL is slightly
elevated but not immediately life-threatening or the primary concern
with digoxin and furosemide therapy. While oxygen saturation of
90% is concerning, it may improve with diuresis and is not the most
critical lab value. Sodium level of 140 mEq/L is within normal limits
and does not pose immediate risk with this medication combination.
Question 3
A patient receives IV furosemide. Which laboratory value requires
immediate follow-up?
,A. Sodium 138 mEq/L
B. Calcium 9.2 mg/dL
C. Magnesium 1.9 mEq/L
D. Potassium 2.8 mEq/L ← CORRECT ANSWER
Rationale: Loop diuretics waste potassium; 2.8 mEq/L indicates
hypokalemia with dysrhythmia risk, especially with digoxin. Sodium
138 mEq/L is normal (135–145). Calcium 9.2 mg/dL is normal (9–
10.5). Magnesium 1.9 mEq/L is normal (1.3–2.1).
Question 4
The nurse understands that thiazide diuretics act primarily at which
nephron site?
A. Ascending loop of Henle
B. Proximal tubule
C. Collecting duct
D. Distal convoluted tubule ← CORRECT ANSWER
Rationale: Thiazides block sodium-chloride reabsorption in the distal
convoluted tubule (DCT). The ascending loop is the site of loop
diuretics. The proximal tubule relates to osmotic/carbonic anhydrase
agents. The collecting duct is where potassium-sparing agents work.
, Question 5
A patient takes digoxin plus furosemide daily. The priority
assessment is:
A. Deep tendon reflexes
B. Bowel sounds
C. Pupillary response
D. Serum potassium ← CORRECT ANSWER
Rationale: Hypokalemia from furosemide potentiates digoxin
toxicity. Reflexes relate to magnesium/neurologic issues, not this
pair. Bowel sounds are not the priority for this medication
combination.
Question 6
A patient with hypertension is prescribed hydrochlorothiazide.
Which assessment finding indicates the medication is having the
desired therapeutic effect?
A. Decreased peripheral edema
B. Increased urine output
C. Weight loss of 2 pounds
D. Blood pressure of 128/78 mm Hg ← CORRECT ANSWER
