  1. When drawing up a mixed dose of regular insulin and NPH in one syringe, what is the correct sequence?

    Answer: Inject air into NPH, inject air into regular, draw regular, then draw NPH

    Air goes into both vials first, then clear (regular) is drawn before cloudy (NPH) so the regular vial is not contaminated with NPH.

  2. A patient using an insulin pump has a glucose of 310 mg/dL and moderate blood ketones, and a correction bolus 2 hours ago did not work. What is the most appropriate next step?

    Answer: Give correction insulin by pen or syringe and change the infusion set

    Persistent hyperglycemia with ketones on a pump suggests insulin delivery failure, so give insulin by injection and replace the infusion set.

  3. During a comprehensive foot exam, protective sensation is tested with which tool?

    Answer: A 5.07/10-g Semmes-Weinstein monofilament

    The 10-g monofilament test, together with one other test such as vibration with a 128-Hz tuning fork, identifies loss of protective sensation.

  4. For a pregnant patient getting the one-step 75-g OGTT for gestational diabetes, which single value meets a diagnostic threshold?

    Answer: 2-hour 155 mg/dL

    One-step thresholds are fasting ≥92, 1-hour ≥180, or 2-hour ≥153 mg/dL, and any one value is enough for the diagnosis.

  5. According to international consensus targets, what percentage of CGM readings should most adults with type 1 or type 2 diabetes have below 54 mg/dL?

    Answer: Less than 1%

    Time below 54 mg/dL (level 2 hypoglycemia) should be under 1%, and time below 70 mg/dL should be under 4%.

  6. After injecting with an insulin pen, how long should the patient hold the needle in the skin before withdrawing it?

    Answer: About 10 seconds

    Holding the pen needle in place for about 10 seconds helps make sure the full dose is delivered and reduces leakage.

  7. A patient's A1C does not match their CGM data, and they have sickle cell trait with recent blood loss anemia. Which test is the better choice for checking glycemic control?

    Answer: Fructosamine or CGM-derived glucose metrics

    Hemoglobin variants and conditions that change red cell turnover make A1C unreliable, so fructosamine or CGM metrics are used instead.
