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 number of tablets needed to provide the prescribed dose of amoxicillin by dividing the dose in mg by the amount of amoxicillin in one tablet
- Calculate the number of tablets needed to provide the prescribed dose of clavulanate by dividing the dose in mg by the amount of clavulanate in one tablet
- Compare the two numbers and choose the larger one as the number of tablets to be administered
Using these steps, we get:
- (number of tablets for amoxicillin) = (2000) / (1000) = 2
- (number of tablets for clavulanate) = (125) / (62.5) = 2
- (number of tablets to be administered) = max(2, 2) = 2
Therefore, the nurse should administer 2 tablets of amoxicillin/clavulanate to the client.
