What professional behaviour is most critical to promote safety in insulin administration?
Delegating the preparation of insulin to an unlicensed assistive personnel (UAP).
Drawing up insulin directly from a mixed vial without clarification.
Double-checking the insulin dose with another licensed nurse before administration.
Administering insulin without verifying the type of insulin ordered.
The Correct Answer is C
A. Delegating the preparation of insulin to an unlicensed assistive personnel (UAP): Delegating insulin preparation to a UAP is unsafe because insulin is a high-alert medication requiring licensed personnel to calculate and administer doses accurately. Delegation in this context increases the risk of dosing errors.
B. Drawing up insulin directly from a mixed vial without clarification: Drawing up insulin from a mixed vial without confirming the order or type can lead to administering the wrong insulin, incorrect dosing, or mixing incompatible insulins, all of which compromise patient safety.
C. Double-checking the insulin dose with another licensed nurse before administration: Verifying the insulin type and dose with a second licensed nurse ensures accuracy and minimizes the risk of medication errors. This practice is a critical safety measure for high-alert medications like insulin.
D. Administering insulin without verifying the type of insulin ordered: Administering insulin without checking the order can result in giving the wrong type, which can lead to hypoglycemia, hyperglycemia, or inadequate glycemic control.

Correct Answer is C
Explanation
A. Enhanced pharmacodynamic responses: Older adults may have altered pharmacodynamic responses, such as increased sensitivity to certain medications, but this alone is not the primary reason for the increased risk of adverse events.
B. Increased volume of distribution: In aging, the volume of distribution for some drugs may change, but these changes are variable and less influential than organ function decline in causing adverse events.
C. Decline in liver and kidney function: Aging commonly leads to decreased hepatic metabolism and renal excretion, which can cause drugs to accumulate in the body. This significantly increases the risk of toxicity and adverse medication events in older adults.
D. Increased absorption in the GI tract: Absorption in the gastrointestinal tract is generally not significantly increased in older adults. Therefore, this factor contributes little to the heightened risk of adverse medication effects.
Correct Answer is A
Explanation
A. 15 mL: One tablespoon is equivalent to 15 milliliters in the metric system, which is the standard conversion used in clinical practice for accurate measurement of liquid medications.
B. 5 mL: This volume corresponds to one teaspoon, not a tablespoon, and using it would underdose the patient if a tablespoon is required.
C. 10 mL: Ten milliliters does not equal a tablespoon. Administering this amount would result in an insufficient dose.
D. 30 mL: Thirty milliliters corresponds to approximately 2 tablespoons or 1 fluid ounce, which would double the intended dose if used incorrectly.
