The healthcare provider prescribes an IV bolus of diltiazem 0.25 mg/kg for a client with atrial fibrillation. The client weighs 178 pounds. How many mg should the nurse administer? (Enter numeric value only. If rounding is required, round to the nearest whole number.)
The Correct Answer is ["20"]
The correct answer is 20 mg. To find the answer, we can use the following steps:
- Convert the client's weight from pounds to kilograms by dividing by 2.2
- Multiply the weight in kilograms by the dosage in mg/kg
- Round the result to the nearest whole number
Using these steps, we get:
- (weight in kg) = (178) / (2.2) = 80.909 kg
- (dose in mg) = (0.25) x (80.909) = 20.227 mg
- (rounded dose in mg) = 20 mg
Therefore, the nurse should administer 20 mg of IV diltiazem to the client.

Correct Answer is ["2"]
Explanation
To find the answer, we can use the following steps:
- Calculate the volume of loratadine suspension in mL by dividing the dose in mg by the concentration in mg/mL
- Convert the volume in mL to teaspoons by multiplying by 0.2
- Round the result to the nearest whole number
Using these steps, we get:
- (volume in mL) = (10) / (5 / 5) = 10 mL
- (volume in teaspoons) = (10) x (0.2) = 2 teaspoons
- (rounded volume in teaspoons) = 2 teaspoons
Therefore, the nurse should instruct the client to take 2 teaspoons of loratadine suspension.
Correct Answer is ["250"]
Explanation
To find the answer, we can use the following formula:
(mL/hour) = (mL/minute) x 60
Substituting the given values, we get:
(mL/hour) = (500 / 120) x 60
Simplifying, we get:
(mL/hour) = 4.167 x 60
(mL/hour) = 250
Therefore, the nurse should program the infusion pump to deliver 250 mL/hour of azithromycin in NS to the patient.
