A client with atrial fibrillation is receiving digoxin (Lanoxin). Which of these assessments is most important for the nurse to perform?
Correct answer
B
Rationale
Measure apical pulse prior to administration. Digitoxin decreases conduction velocity through the AV node and prolongs the refractory period. If the apical heart rate is less than 60 beats/minute, withhold the drug. The apical pulse should be taken with a stethoscope so that there will be no mistake about what the heart rate actually is.
