Which type of insulin is most appropriate to administer to a patient 15 minutes before a meal to manage postprandial glucose levels?
Insulin glargine
NPH insulin
Insulin lispro
Regular insulin
The Correct Answer is C
A. Insulin glargine: Insulin glargine is a long-acting basal insulin with no pronounced peak, used to maintain baseline glucose control. It is not intended for rapid correction of postprandial glucose elevations or administration immediately before meals.
B. NPH insulin: NPH insulin is an intermediate-acting insulin with an onset of 1 to 2 hours and a pronounced peak several hours later. Its timing does not align with immediate postprandial glucose rises.
C. Insulin lispro: Insulin lispro is a rapid-acting insulin with an onset of approximately 10 to 15 minutes, making it ideal for administration shortly before meals. It effectively controls postprandial glucose spikes by matching insulin action with carbohydrate absorption.
D. Regular insulin: Regular insulin has an onset of 30 to 60 minutes and is typically administered 30 minutes before meals. It does not act quickly enough to optimally manage glucose levels when given 15 minutes prior to eating.

Correct Answer is B
Explanation
A. To identify the therapeutic class of the medication: Knowing the therapeutic class can provide context for its use, but it does not prevent administration errors or ensure the correct drug is given.
B. To ensure the correct medication is given to the right patient: Verifying the medication name multiple times is critical to prevent medication errors, particularly with drugs that have similar names. This step ensures the intended drug is administered safely to the correct patient.
C. To confirm the manufacturing date of the drug: While checking expiration or manufacturing dates is important for safety, it does not replace verification of the medication’s identity for accurate administration.
D. To determine the storage conditions required: Storage information helps maintain drug stability, but it is not the reason for multiple checks of the medication name before administration.
Correct Answer is A
Explanation
A. Medication reconciliation: Medication reconciliation involves reviewing and verifying a patient’s complete medication list during transitions of care, such as admission, transfer, or discharge. This process ensures accuracy, prevents omissions or duplications, and reduces the risk of adverse drug events.
B. Therapeutic drug monitoring: Therapeutic drug monitoring focuses on measuring specific drug levels in the patient’s blood to maintain a therapeutic range, not on reviewing the medication list during transfers.
C. Pharmacokinetics: Pharmacokinetics is the study of how the body absorbs, distributes, metabolizes, and excretes medications. While important for dosing, it does not involve reviewing a patient’s medication list.
D. Incident reporting: Incident reporting involves documenting errors, near misses, or adverse events in clinical practice. Reviewing medications during transfer is a preventive action, not an incident report.
