A primary healthcare provider prescribes 14 units of insulin to a client.
What should a nurse do while administering this medication to the client?
Administer 14 units of medication SubQ in a U-100 syringe
Administer 14 units of medication SubQ in two divided doses in a U-100 syringe
Administer 14 units of medication SubQ in one dose in a tuberculin syringe
Administer 14 units of medication SubQ in the morning after breakfast in a tuberculin syringe
The Correct Answer is A
Insulin is a hormone that helps regulate blood sugar levels. It is usually injected into the fat layer just under the skin (subcutaneous or SubQ) using a syringe and needle or a pen-like device². Insulin syringes are marked in units of insulin, not milliliters or cubic centimeters. The most common insulin syringe holds 1 mL of fluid and has markings for 100 units of insulin². A U-100 syringe means that for every 1 mL of fluid, there are 100 units of insulin³.
To administer 14 units of insulin, you would need to draw up 0.14 mL of fluid in a U-100 syringe. You would inject the insulin into your abdomen, upper arm, butocks, hip, or the front or side of the thigh¹. You would use a different area within the site each time you inject insulin to prevent lumps, swelling, or thickened skin¹.
The other options are incorrect because:
b) There is no need to divide the dose into two injections. This would increase the risk of infection and pain.
c) A tuberculin syringe is not designed for insulin administration. It is marked in milliliters or cubic centimeters, not units of insulin. Using a tuberculin syringe could result in an incorrect dose of insulin.
d) The timing of insulin administration depends on the type and duration of insulin. Some insulins are taken before meals, some are taken after meals, and some are taken once or twice a day. The primary healthcare provider should specify when to take the insulin.

Correct Answer is A
Explanation
The nurse should administer 0.35 mcg of medication to the infant.
This answer is correct because it is based on a simple multiplication calculation. The nurse should multiply the prescribed dose per kilogram by the infant's weight in kilograms to get the total dose in micrograms, as follows:
0.05 mcg/kg x 7 kg = 0.35 mcg
Therefore, the nurse should administer 0.35 mcg of medication to the infant.
Correct Answer is C
Explanation
To find the hours to finish the infusion, you need to calculate the following:
- The volume of saline solution in milliliters
- The time in hours using the formula: Time (h) = Total volume (mL) / Infusion rate (mL/h)
First, convert the volume of saline solution from liters to milliliters by multiplying by 1000:
1.5 L x 1000 = 1500 mL
Next, use the formula for time to find how many hours it will take to infuse the saline solution at the current rate:
Time (h) = Total volume (mL) / Infusion rate (mL/h)
Since the total volume is 1500 mL and the infusion rate is 75 mL/h, plug in these values into the formula:
Time (h) = 1500 mL / 75 mL/h
Simplify and solve for the time:
Time (h) = 20 h
Therefore, it will take **20 hours** to finish the infusion at the current rate.
