What is the appropriate insulin syringe to use for administering 50 units of U-100 insulin?
A tuberculin syringe calibrated in milliliters.
AU-100 insulin syringe calibrated for up to 50 units.
AU-500 insulin syringe calibrated for 500 units.
A 1-mL syringe calibrated in milliliters.
The Correct Answer is B
A. A tuberculin syringe calibrated in milliliters: Tuberculin syringes are calibrated in milliliters, not insulin units. Using them for insulin increases the risk of dose miscalculation and medication errors, especially with high-alert drugs like insulin.
B. A U-100 insulin syringe calibrated for up to 50 units: A U-100 insulin syringe is specifically designed to measure U-100 insulin accurately. A syringe calibrated up to 50 units allows precise dosing without excess space, reducing the risk of dosing errors.
C. A U-500 insulin syringe calibrated for 500 units: U-500 syringes are intended only for highly concentrated insulin. Using this syringe for U-100 insulin would result in a major dosing error and potential severe hypoglycemia.
D. A 1-mL syringe calibrated in milliliters: Although a 1-mL syringe can physically hold the volume, it is not calibrated in insulin units. This makes accurate insulin measurement difficult and unsafe compared with a dedicated insulin syringe.

Correct Answer is A
Explanation
A. 30 mL: One fluid ounce is equivalent to approximately 29.6 mL, which is commonly rounded to 30 mL for safe and practical medication calculations. This standard conversion is widely used in nursing practice.
B. 60 mL: Sixty milliliters equals 2 ounces, not 1 ounce. Using this value would result in administering double the intended volume.
C. 120 mL: One hundred twenty milliliters equals 4 ounces. This conversion is significantly higher than the correct amount and would lead to a major dosing error.
D. 15 mL: Fifteen milliliters equals 0.5 ounce or 1 tablespoon. This value is too small to represent 1 ounce and would result in underdosing.
Correct Answer is D
Explanation
A. It identifies whether the medication is generic or brand name: While the label may indicate the medication name, the dosage strength specifically does not determine whether the drug is generic or brand; it focuses on the amount of active ingredient per unit.
B. It provides storage instructions for the medication: Storage instructions are typically included on the label separately, but the dosage strength itself does not guide storage requirements.
C. It helps calculate the total volume of medication needed: Dosage strength can assist in calculations, especially for liquid medications, but its primary purpose is not volume calculation; calculations depend on both prescribed dose and concentration.
D. It ensures the nurse administers the correct amount of medication: The dosage strength indicates how much active drug is present per tablet, capsule, or milliliter. Knowing this allows the nurse to administer the correct dose safely, preventing underdosing or overdosing and ensuring therapeutic effectiveness.
