Answer and Explanation

The Correct Answer is ["538"]

1. Convert pounds to kilograms: 1 pound = 0.453592
158 lbs x 0.453592 kg/lb ≈ 71.71 kg

2. Calculate the total daily dosage:
15 mg/kg/day x 71.71 kg ≈ 1075.65 mg/day

3. Calculate the dosage per dose (divided equally every 12 hours):
1075.65 mg/day / 2 doses ≈ 537.83 mg/dose

4. Round to the nearest whole number:
537.83 mg ≈ 538 mg

Correct Answer is ["0.4"]

Explanation

To determine the correct volume to administer, follow these steps:

1. Convert the available concentration to mg/mL:
6 grams = 6000 mg (since 1 gram = 1000 mg)
Therefore, 6000 mg / 10 mL = 600 mg/mL.

2. Calculate the volume to administer:
The ordered dose is 250 mg.
Volume to administer = 250 mg / 600 mg/mL = 0.4167 mL.

3. Round to the nearest tenth:
0.4167 mL rounded to the nearest tenth is 0.4 mL.

Correct Answer is ["18"]

Explanation

To determine the correct IV pump rate for the heparin infusion, follow these steps:

1. Convert the patient’s weight from pounds to kilograms:
1 pound = 0.453592 kilograms
220 pounds x 0.453592 = 99.79 kilograms (rounded to two decimal places)

2. Calculate the dosage in units per hour:
18 units/kg/hr x 99.79 kg = 1796.22 units/hr

3. Determine the volume of heparin solution needed per hour:
The medication is supplied as 25000 units in 250 mL.
Therefore, the concentration is 100 units/mL.
1796.22 units/hr / 100 units/mL = 17.96 mL/hr

4. So, the nurse should set the IV pump to 18 mL/hour (rounded to the nearest whole number).
