RASMUSSEN PHARMACOLOGY EXAM 3 – HARD QUESTIONS WITH RATIONALES
SECTION 1: ADVANCED CARDIOVASCULAR PHARMACOLOGY – ANTIARRHYTHMICS
& THROMBOLYTICS (Questions 1-30)
1. A patient with atrial fibrillation is prescribed amiodarone after failing treatment
with a Class I antiarrhythmic agent. The nurse understands that amiodarone is
unique among antiarrhythmics because it possesses all four Vaughn-Williams
class properties. The nurse should prioritize monitoring for which potentially fatal
adverse effect that is specifically associated with amiodarone's unique
pharmacokinetic profile and tissue accumulation characteristics?
A) Hepatotoxicity requiring monthly liver function monitoring
B) Pulmonary fibrosis requiring baseline and annual pulmonary function tests
C) Nephrotoxicity requiring daily serum creatinine assessment
D) Cardiotoxicity requiring continuous telemetry monitoring
Correct Answer: B
Rationale: Amiodarone has a long half-life (up to 100 days) and accumulates in tissues,
including lung tissue. Pulmonary fibrosis is a potentially fatal adverse effect that
requires baseline and annual pulmonary function tests and chest X-rays.
2. The nurse is caring for a patient receiving an intravenous infusion of sodium
nitroprusside for hypertensive crisis. The nurse notes that the infusion bag is
covered with an opaque cover. The patient asks why the infusion is covered. Which
response by the nurse is most accurate regarding the protection of this medication
from degradation?
, Page 2 of 88
A) "The cover protects the medication from light, which can degrade sodium
nitroprusside and produce cyanide"
B) "The cover maintains the medication at the correct temperature for optimal stability"
C) "The cover prevents air from entering the infusion and causing bacterial
contamination"
D) "The cover protects the medication from being accidentally administered too rapidly"
Correct Answer: A
Rationale: Sodium nitroprusside is photosensitive and degrades when exposed to light,
producing cyanide. The opaque cover protects the infusion from light degradation and
prevents cyanide toxicity.
3. A patient is receiving alteplase (tPA) for an acute ischemic stroke. The nurse
should recognize that alteplase is a thrombolytic agent that works by converting
plasminogen to plasmin. Which assessment finding would be the most concerning
and should be reported to the provider immediately as it may indicate a life-
threatening complication of thrombolytic therapy?
A) Mild headache and nausea
B) Blood pressure of 150/90 mmHg
C) Sudden severe headache, nausea, and neurological decline
D) Heart rate of 88 beats per minute with occasional premature ventricular contractions
Correct Answer: C
Rationale: Sudden severe headache, nausea, and neurological decline in a patient
receiving tPA may indicate intracranial hemorrhage, the most serious complication of
thrombolytic therapy. This requires immediate notification of the provider and
emergency interventions.
4. The nurse is administering adenosine to a patient with supraventricular
tachycardia. The nurse understands that adenosine works by slowing conduction
through the AV node. Which statement about the administration of adenosine is
most accurate regarding the required technique to ensure therapeutic
effectiveness?
A) Administer as a slow IV push over 5 minutes to prevent adverse effects
B) Administer as a rapid IV push followed by a normal saline flush to ensure complete
delivery to the central circulation
C) Administer as an intramuscular injection for rapid absorption
D) Administer as a subcutaneous injection to achieve steady-state levels
, Page 3 of 88
Correct Answer: B
Rationale: Adenosine has a very short half-life (less than 10 seconds). It must be
administered as a rapid IV push followed by a normal saline flush to ensure it reaches
the central circulation and the AV node before being metabolized.
5. The nurse is caring for a patient who has been prescribed digoxin and is now
receiving amiodarone. The nurse understands that amiodarone significantly
increases digoxin levels by which mechanism, and the nurse should anticipate
which specific monitoring adjustment to prevent digoxin toxicity?
A) Amiodarone increases renal excretion of digoxin, requiring a higher digoxin dose
B) Amiodarone displaces digoxin from protein-binding sites and decreases digoxin
clearance, requiring the digoxin dose to be reduced by approximately 50%
C) Amiodarone increases digoxin absorption from the gastrointestinal tract, requiring
the digoxin to be taken with food
D) Amiodarone decreases digoxin distribution to tissues, requiring more frequent
monitoring
Correct Answer: B
Rationale: Amiodarone increases digoxin levels by displacing it from protein-binding
sites and decreasing renal clearance. The digoxin dose should be reduced by
approximately 50% when starting amiodarone, and levels should be monitored closely.
6. A patient is receiving lidocaine for the management of ventricular arrhythmias.
The nurse should monitor the patient for which early sign of lidocaine toxicity that
would require immediate intervention and discontinuation of the medication?
A) Tachycardia and hypertension
B) Confusion, drowsiness, and paresthesias
C) Constipation and urinary retention
D) Hyperglycemia and weight gain
Correct Answer: B
Rationale: Early signs of lidocaine toxicity are neurological and include confusion,
drowsiness, paresthesias (numbness and tingling), and tinnitus. These symptoms
require immediate intervention and dose reduction or discontinuation.
7. The nurse is caring for a patient who has been prescribed dronedarone for the
management of atrial fibrillation. The nurse understands that dronedarone is a
noniodinated amiodarone derivative developed to reduce the adverse effect

profile. Which specific monitoring parameter is most critical for this patient to
prevent a life-threatening complication associated with this medication?
A) Serum potassium and magnesium levels to prevent QT prolongation
B) Serum creatinine and BUN to assess for nephrotoxicity
C) Liver function tests to assess for hepatotoxicity
D) Complete blood count to assess for agranulocytosis
Correct Answer: A
Rationale: Dronedarone can prolong the QT interval, increasing the risk of torsades de
pointes. Serum potassium and magnesium levels should be monitored and maintained
within normal range to prevent this life-threatening arrhythmia.
8. A patient with acute myocardial infarction is prescribed morphine, oxygen,
nitroglycerin, and aspirin (MONA). The nurse understands that morphine is
included in this protocol for which primary purpose beyond pain relief?
A) To reduce anxiety and improve patient compliance
B) To decrease preload and afterload, reducing myocardial oxygen demand
C) To prevent the development of pulmonary edema
D) To increase the heart rate and improve cardiac output
Correct Answer: B
Rationale: Morphine reduces pain, anxiety, and dyspnea. It also decreases preload and
afterload through venodilation, which reduces myocardial oxygen demand and is
beneficial in acute myocardial infarction.
9. The nurse is preparing to administer alteplase (tPA) to a patient with an acute
ischemic stroke. The nurse should recognize that this medication is
contraindicated in which patient condition that would significantly increase the
risk of fatal hemorrhage?
A) Blood pressure of 150/90 mmHg
B) History of hypertension
C) Recent (within 3 months) intracranial or intraspinal surgery
D) Age greater than 75 years
Correct Answer: C
Rationale: Recent intracranial or intraspinal surgery is an absolute contraindication to
tPA administration due to the high risk of hemorrhage. Other contraindications include
active bleeding, severe hypertension, and recent stroke.
