RASMUSSEN PHARMACOLOGY EXAM 300 ACTUAL
QUESTIONS AND CORRECT ANSWERS WITH
RATIONALE LATEST UPDATE ALREADY GRADED A+
The Rasmussen Pharmacology Exam 2 is a comprehensive nursing examination
designed to assess students' mastery of pharmacological principles, including drug
classifications, mechanisms of action, therapeutic effects, adverse reactions, and
nursing considerations for safe medication administration. The exam covers major
drug categories such as diuretics, anticoagulants, cardiac medications,
antimicrobials, endocrine agents, central nervous system drugs, and
psychopharmacological agents. Key areas of focus include fluid and electrolyte
balance, bleeding risk monitoring, antibiotic stewardship, and patient education
regarding drug interactions and side effects. Students must demonstrate critical
thinking in applying pharmacological knowledge to clinical scenarios, prioritizing
patient safety, and recognizing life-threatening complications like digoxin toxicity,
heparin-induced thrombocytopenia, and anaphylactic reactions to antibiotics.
Section 1: Diuretics and Cardiovascular Medications (Questions 1-60)
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) Furosemide (Lasix)
c) Mannitol (Osmitrol)
d) Spironolactone (Aldactone)
Answer: b
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 has a
slower onset and is not appropriate for acute pulmonary edema. Mannitol is used
,for increased intracranial pressure, not pulmonary edema, and can worsen
pulmonary congestion. Spironolactone has weak diuretic effects and a slow onset,
not suitable for acute management.
Question 2
A patient who is taking digoxin is admitted for congestive heart failure. The
prescriber orders furosemide. Which laboratory value causes the nurse the most
concern?
a) Blood glucose level of 120 mg/dL
b) Oxygen saturation of 90%
c) Potassium level of 3.5 mEq/L
d) Sodium level of 140 mEq/L
Answer: c
Rationale: Hypokalemia (3.5 mEq/L) increases the risk of digoxin toxicity and
fatal dysrhythmias. Furosemide causes potassium loss through the distal nephron.
While oxygen saturation of 90% is concerning, it may improve with diuresis and is
not the most critical lab value. The sodium level is within normal limits. Blood
glucose of 120 mg/dL is slightly elevated but not immediately life-threatening.
Question 3
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) Blood pressure of 128/78 mm Hg
d) Weight loss of 2 pounds
Answer: c
Rationale: The desired therapeutic effect of hydrochlorothiazide for hypertension is
blood pressure reduction to target range. While increased urine output, decreased
edema, and weight loss indicate diuresis, they are not the primary therapeutic goal
for hypertension management.
Question 4
The nurse understands that thiazide diuretics act primarily at which nephron site?
a) Distal convoluted tubule
b) Ascending loop of Henle
c) Proximal tubule
d) Collecting duct
,Answer: a
Rationale: Thiazide diuretics block sodium-chloride reabsorption in the distal
convoluted tubule. Loop diuretics act on the ascending loop of Henle. Osmotic and
carbonic anhydrase agents affect the proximal tubule. Potassium-sparing agents
work on the collecting duct.
Question 5
A patient takes digoxin plus furosemide daily. The priority assessment is:
a) Serum potassium
b) Deep tendon reflexes
c) Bowel sounds
d) Pupillary response
Answer: a
Rationale: Hypokalemia from furosemide potentiates digoxin toxicity, increasing
the risk of fatal dysrhythmias. Serum potassium must be monitored closely. Deep
tendon reflexes relate to magnesium and neurologic issues, not this drug
combination. Bowel sounds and pupillary response are not the priority interaction
concerns.
Question 6
Which agent is a potassium-sparing diuretic?
a) Spironolactone (Aldactone)
b) Bumetanide (Bumex)
c) Ethacrynic acid (Edecrin)
d) Chlorothiazide (Diuril)
Answer: a
Rationale: Spironolactone is an aldosterone antagonist that retains potassium while
promoting sodium and water excretion. Bumetanide and ethacrynic acid are loop
diuretics that cause potassium loss. Chlorothiazide is a thiazide diuretic that also
causes potassium loss.
Question 7
A patient is prescribed furosemide for heart failure. The nurse should instruct the
patient to report which symptom immediately?
a) Headache
b) Muscle cramps
c) Tinnitus
, d) Dry mouth
Answer: c
Rationale: Tinnitus (ringing in the ears) signals ototoxicity, a serious adverse effect
of furosemide. The dose must be held and the provider notified. While muscle
cramps may indicate electrolyte imbalances, tinnitus is a more urgent concern.
Question 8
A patient with heart failure is prescribed spironolactone. Which laboratory value
requires the most immediate nursing intervention?
a) Sodium of 138 mEq/L
b) Chloride of 100 mEq/L
c) Potassium of 5.8 mEq/L
d) BUN of 18 mg/dL
Answer: c
Rationale: Spironolactone is a potassium-sparing diuretic that can cause
hyperkalemia. A potassium of 5.8 mEq/L is dangerously elevated and requires
immediate intervention. Sodium, chloride, and BUN values are within normal
limits.
Question 9
A patient is prescribed furosemide and digoxin. Which electrolyte imbalance
would increase the risk of digoxin toxicity?
a) Hyponatremia
b) Hypokalemia
c) Hypercalcemia
d) Hypermagnesemia
Answer: b
Rationale: Hypokalemia potentiates digoxin's effects on cardiac tissue, increasing
the risk of dysrhythmias and digoxin toxicity. Furosemide causes potassium
wasting. Hyponatremia, hypercalcemia, and hypermagnesemia do not directly
increase digoxin toxicity risk to the same degree.
Question 10
A patient with pulmonary edema is prescribed furosemide IV push. The nurse
should administer the medication over how many minutes to prevent adverse
effects?
a) 1-2 minutes
