A physician orders a medication of 140 mcg/kg/min for a patient weighing 176 lb. The infusion will last 6 min.
How many milligrams should the nurse administer to the patient?
11.2 mg
147.8 mg
67.2 mg
670.2 mg
670.2 mg
The Correct Answer is C
To calculate the total amount of medication in milligrams that the nurse should administer to the patient, we need to determine the dosage per minute based on the patient's weight and the ordered dose, and then multiply it by the total infusion time.
First, let's convert the patient's weight from pounds to kilograms:
176 lb / 2.2046 = 79.83 kg (rounded to the nearest hundredth)
Now, let's calculate the dosage per minute:
Dosage per minute = dose per kg/min x weight in kg Dosage per minute = 140 mcg/kg/min x 79.83 kg
To convert mcg to mg, divide by 1000:
Dosage per minute = (140 mcg/kg/min x 79.83 kg) / 1000
Next, let's calculate the total amount of medication in milligrams:
Total medication = dosage per minute (mg/min) x total infusion time (min) Total medication = (Dosage per minute x 6 min)
Calculating the total medication: Total medication = 66.3 mg
Therefore, the nurse should administer approximately 66.3 mg of medication to the patient, which corresponds to option c. 67.2 mg.

Correct Answer is A
Explanation
To calculate the rate of infusion required for the continuous intravenous (IV) infusion of 1.5 L of normal saline (NS) over 24 hours, we need to divide the total volume (1500 ml) by the total time (24 hours).
1500 ml / 24 hours = 62.5 ml/hr
Therefore, the rate of infusion that should be set in the infusion pump is a. 62.5 mL/hr.
B. 41.7 mL/hr: This rate is too low and would result in the infusion taking longer than the prescribed 24 hours.
C. 20.8 mL/hr: This rate is even lower and would result in an even longer infusion time, which is not consistent with the prescribed 24 hours.
D. 83.3 mL/hr: This rate is too high and would result in the infusion being delivered faster than the prescribed 24 hours.
Therefore, the correct rate of infusion to be set in the infusion pump for the continuous IV infusion of 1.5 L of normal saline over 24 hours is a. 62.5 mL/hr, as it ensures the prescribed volume is infused within the specified time frame.
Correct Answer is D
Explanation
The dose of ondansetron for this client can be calculated by multiplying the prescribed dose per kg by the
client's weight: 0.34 mg/kg * 70 kg = 23.8 mg.
A. 6.8 mg is incorrect because it is less than the calculated dose.
B. 205.9 mg is incorrect because it is more than the calculated dose.
C. 2.3 mg is incorrect because it is less than the calculated dose.
D. 23.8 mg is the correct answer.
