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 B
Explanation
To find the milliliters per dose, you need to use the formula for dosage calculation:
Volume (mL) = Dose ordered (mg) / Concentration (mg/mL) x Volume available (mL)
Since the dose ordered is 0.5 grams, the concentration is 125 mg/5 mL, and the volume available is 5 mL, plug in these values into the formula:
Volume (mL) = 0.5 grams / 125 mg/5 mL x 5 mL
However, before you can simplify and solve for the volume, you need to convert the dose from grams to milligrams by multiplying by 1000:
Volume (mL) = 500 mg / 125 mg/5 mL x 5 m
Simplify and solve for the volume:
Volume (mL) = 20 mL
Therefore, the nurse should administer **20 mL** of Amoxil per dose to the patient.
Correct Answer is B
Explanation
To find the dose of ondansetron, you need to use the formula for weight-based dosage calculation:
Dose (mg) = Weight (kg) x Prescribed dose (mg/kg)
Since the client's weight is 70 kg and the prescribed dose is 0.34 mg/kg, plug in these values into the formula:
Dose (mg) = 70 kg x 0.34 mg/kg
Simplify and solve for the dose:
Dose (mg) = 23.8 mg
Therefore, the client should receive **23.8 mg** of ondansetron prior to chemotherapy.
