A nurse evaluates medication administration record (MAR) listed below for a client with the following rhythm.
Lisinopril 10 mg PO daily
Digoxin 0.125 mcg PO daily
Warfarin 5 mg PO every other day
Furosemide 20 mg PO Daily
Which medication would the nurse expect to find on this client's medication administration record to prevent a common complication of this condition?
Digoxin
Warfarin
Furosemide
Lisinopril
The Correct Answer is B
A. Digoxin is used to control the heart rate in atrial fibrillation but does not directly prevent the common complication of thromboembolism.
B. Warfarin is an anticoagulant used to prevent thromboembolic complications, such as stroke, which are common in atrial fibrillation due to the formation of clots in the atria.
C. Furosemide is a diuretic used to manage fluid retention, often in heart failure, but it does not prevent thromboembolism.
D. Lisinopril is an ACE inhibitor used to manage hypertension and heart failure, but it does not prevent thromboembolic complications.

Correct Answer is C
Explanation
A. This is an underestimation due to a miscalculation of the dose rate.
B. This is an overestimation due to a miscalculation of the dose rate.
C. 1. Calculate the desired dose of dobutamine:
Desired dose (mcg/min) = Dose per kg (mcg/kg/min) x Weight (kg)
Desired dose (mcg/min) = 12 mcg/kg/min x 75 kg = 900 mcg/min
2. Convert mcg/min to mg/hr:
900 mcg/min x 60 min/hr = 54,000 mcg/hr
54,000 mcg/hr ÷ 1000 mcg/mg = 54 mg/hr
3. Calculate the concentration of dobutamine in the solution:
Concentration (mg/mL) = Total amount of dobutamine (mg) / Total volume (mL)
Concentration (mg/mL) = 1000 mg (1 g) / 250 mL = 4 mg/mL
4. Calculate the infusion rate (mL/hr):
Infusion rate (mL/hr) = Desired dose (mg/hr) / Concentration (mg/mL)
Infusion rate (mL/hr) = 54 mg/hr / 4 mg/mL = 13.5 mL/hr
5. Round to the nearest whole number:
Infusion rate (mL/hr) = 14 mL/hr
Therefore, the IV pump should be programmed for 14 mL/hr.
D. This is an overestimation due to a miscalculation of the dose rate.
Correct Answer is B
Explanation
A. Assessing oral temperature is not a priority immediately after an electrical burn, as the focus should be on monitoring for cardiac issues and other life-threatening conditions.
B. Electrical burns can cause cardiac arrhythmias, including dysrhythmias like ventricular fibrillation, which can be life-threatening. The nurse should place the client on a cardiac monitor immediately to detect any abnormal rhythms and respond accordingly.
C. While checking potassium levels is important for assessing potential complications such as kidney damage or arrhythmias, cardiac monitoring should take precedence.
D. Assessing for pain at contact points is important, but it is secondary to ensuring cardiac stability in an electrical burn victim.
