Question

A patient requires 3 units of insulin every 12 hours. If the concentration of insulin is 100 units/ml, how many milliliters should be given at each administration?

1. 0.36 ml
2. 0.75 ml
3. 1.5 ml
4. 0.03 ml

Answer 1

To determine the volume of insulin to be given, the concentration of insulin and the desired units must be considered. In this case, the correct volume is 0.03 mL.

Step-by-step explanation:

To calculate the volume of insulin that should be given at each administration, we need to find the number of milliliters required to deliver 3 units of insulin. We can use the concentration of insulin (100 units/mL) to determine the volume needed.

First, we set up a proportion using the given concentration:

100 units/mL = 3 units/x mL

Cross-multiply and solve for x:

100x = 3 * 1

x = 3/100

x = 0.03 mL

Therefore, the correct answer is 0.03 mL, which is option 4.
