A client with human immunodeficiency virus (HIV) begins active labor at 38 weeks gestation and receives a prescription for zidovudine 2 mg/kg IV, to be administered over 1 hour. The client weighs 185 lbs. Based on the client's weight, how many mg should the nurse prepare to administer? (Enter numerical value only. If rounding is required, round to the nearest whole number.)

Answer and Explanation

The Correct Answer is ["168"]

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) = (185) / (2.2) = 84.091 kg

- (dose in mg) = (2) x (84.091) = 168.182 mg

- (rounded dose in mg) = 168 mg

Therefore, the nurse should prepare to administer 168 mg of zidovudine IV to the client.

Correct Answer is ["15"]

Explanation

To find the answer, we can use the following steps:

- Calculate the infusion rate in mL/hour by dividing the volume of IV fluids by the time of infusion

- Calculate the infusion rate in mL/minute by dividing the infusion rate in mL/hour by 60

- Multiply the infusion rate in mL/minute by the drop factor in gtt/mL to get the infusion rate in gtt/minute

- Round the result to the nearest whole number

Using these steps, we get:

- (infusion rate in mL/hour) = (630) / (7) = 90 mL/hour

- (infusion rate in mL/minute) = (90) / (60) = 1.5 mL/minute

- (infusion rate in gtt/minute) = (1.5) x (10) = 15 gtt/minute

- (rounded infusion rate in gtt/minute) = 15

Therefore, the nurse should regulate the infusion to deliver 15 gtt/minute of IV fluids to the client.

Correct Answer is ["20"]

Explanation

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.
