The Correct Answer is D
Choice A rationale
A 2-hour blood glucose level of 132 mg/dL is below the threshold for diabetes diagnosis, which is 200 mg/dL or higher.
Choice B rationale
An HbA1c level of 5.2% is within the normal range. Diabetes is diagnosed with an HbA1c of 6.5% or higher.
Choice C rationale
A casual blood glucose level of 178 mg/dL is elevated but not diagnostic of diabetes. Diabetes is diagnosed with a casual blood glucose level of 200 mg/dL or higher.

Correct Answer is A
Explanation
Choice A rationale
Regular insulin should be clear. If it appears cloudy, it may be contaminated or expired, and should be discarded. This is a correct instruction for self-administering regular insulin and NPH insulin from the same syringe.
Choice B rationale
When mixing insulins, regular insulin should be drawn up first, followed by NPH insulin. Drawing up NPH insulin first can lead to contamination of the regular insulin with the cloudy NPH insulin.
Choice C rationale
NPH insulin should be gently rolled or inverted to mix, not shaken. Shaking can cause bubbles, which can lead to inaccurate dosing.
Choice D rationale
Air should be injected into the NPH insulin vial first, not the regular insulin vial. This helps prevent contamination and ensures accurate dosing.
