CLASSIFICATIONS
200 Rigorous Clinical Questions with Step-by-Step Dosage Calculations
and Rationales
SECTION 1: Antiarrhythmic Agents (Questions 1 - 30)
Question 1: A patient with heart failure is prescribed Digoxin 0.125 mg
PO daily. Available are 0.25 mg scored tablets. How many tablets
should the nurse administer?
A) 0.25 tablets
B) 0.5 tablets
C) 1 tablet
D) 2 tablets
Correct Answer: B) 0.5 tablets
Rationale: Using (Desired/Have) x Quantity: (0.125 mg / 0.25 mg) x
1 = 0.5 tablets. Assess apical pulse for 1 full minute prior to
administration.

B) Withhold medication, assess patient vitals, and notify the
prescribing provider
C) Double the subsequent dose
D) Administer half the dose sublingually
Correct Answer: B) Withhold medication, assess patient vitals,
and notify the prescribing provider
Rationale: Clinical rationale for question 2: Emphasizes priority
, nursing assessment, safety protocols, and evidence-based
pharmacokinetics in cardiac care.
