A client is receiving a continuous infusion of IV insulin at 8mL/hr. Pharmacy makes an infusion of 75 units of regular insulin in 150mL of Normal Saline for this instruction. How many units per hour is the client receiving? Use a preceding zero if it applies. Do not use a trailing zero.
The Correct Answer is ["4"]
To determine the number of units per hour the client is receiving, follow these steps:
1. Calculate the concentration of insulin in units per mL:
The infusion contains 75 units of insulin in 150 mL of Normal Saline.
Therefore, 75 units / 150 mL = 0.5 units/mL.
2. Determine the infusion rate in units per hour:
The infusion rate is 8 mL per hour.
Using the concentration, 8 mL/hr x 0.5 units/mL = 4 units/hr.

Correct Answer is ["7.5"]
Explanation
To determine the correct volume to administer, follow these steps:
1. Calculate the dosage in units:
The dosage is 0.1 unit/kg.
The patient weighs 75 kg.
Total dosage = 0.1 unit/kg x 75 kg = 7.5 units.
2. Determine the volume to administer:
The insulin is supplied as 100 units in 100 mL.
Therefore, the concentration is 1 unit/mL.
Volume to administer = 7.5 units / 1 unit/mL = 7.5 mL.
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.
