1. A nurse is preparing to administer insulin lispro to a patient with Type 1 Diabetes. When is
the most appropriate time to administer this medication?
A. 30 to 60 minutes before a meal
B. Immediately after the patient finished eating
C. At bedtime
D. 15 minutes before a meal
Correct Answer: D
Insulin lispro is a rapid-acting insulin with an onset of 15 minutes. It should be given
within 15 minutes of a meal to prevent hypoglycemia.
2. A patient is prescribed metformin for Type 2 Diabetes. Which laboratory value should the
nurse monitor most closely to prevent lactic acidosis?
A. Serum Potassium
B. Hemoglobin A1C
C. Alanine Aminotransferase (ALT)
,D. Glomerular Filtration Rate (GFR)
Correct Answer: D
Metformin is excreted by the kidneys. Renal impairment, indicated by a low GFR,
increases the risk of metformin accumulation and subsequent lactic acidosis.
3. When teaching a patient about mixing insulin NPH and insulin Regular in one syringe,
which step is correct?
A. Draw up NPH first, then Regular
B. Wait 10 minutes after mixing before injecting
C. Shake the NPH vial vigorously before drawing
D. Draw up Regular first, then NPH
Correct Answer: D
To prevent contaminating the clear (Regular) insulin with the cloudy (NPH) insulin, the
‘clear before cloudy’ rule is followed.
4. A patient taking glipizide, a sulfonylurea, reports feeling dizzy and shaky. What is the
nurse’s priority action?
A. Administer the next scheduled dose
B. Provide a high-protein snack
C. Call the healthcare provider immediately
D. Check the patient’s blood glucose level

Dizziness and shakiness are clinical signs of hypoglycemia, a common adverse effect of
sulfonylureas. Checking blood glucose is the priority assessment.
5. Which statement regarding insulin glargine is correct?
A. It has a peak effect at 6 to 8 hours
B. It can be safely mixed with other insulins
C. It provides a steady basal rate for 24 hours
D. It is administered intravenously during DKA
Correct Answer: C
Insulin glargine is long-acting and peakless, providing basal glycemic control for
approximately 24 hours. It should never be mixed with other insulins.
6. A patient is prescribed pioglitazone. The nurse should notify the provider if the patient
