1. A nurse is preparing to administer Lispro (Humalog) insulin to a patient. Which action is
most appropriate regarding the timing of administration?
A. Administer the dose 30 to 60 minutes before the meal arrives.
B. Ensure the patient has their meal tray in front of them within 15 minutes of
administration.
C. Give the medication only after the patient has finished their entire meal.
D. Administer the insulin immediately before the patient goes to sleep at night.
Correct Answer: B
Expert Explanation: Lispro is a rapid-acting insulin with an onset of action between 15 to
30 minutes. It is critical that the patient eats shortly after administration to prevent severe
hypoglycemia. The nurse should verify that the meal is present or arriving immediately
before giving the injection.
2. A patient is prescribed Metformin for Type 2 Diabetes Mellitus. Which upcoming diagnostic
test would require the nurse to hold this medication?
A. A routine chest X-ray for pneumonia screening.
B. A computed tomography (CT) scan with intravenous contrast dye.
C. An abdominal ultrasound for gallbladder disease.
,D. An electrocardiogram (ECG) to monitor heart rhythm.
Correct Answer: B
Expert Explanation: Metformin must be discontinued 48 hours before and after
procedures involving iodine-based contrast media. The combination of metformin and
contrast can significantly increase the risk of lactic acidosis and acute renal failure. Normal
renal function must be confirmed before resuming the medication after the procedure.
3. The nurse is providing education to a patient newly prescribed Levothyroxine (Synthroid).
What is the most important instruction regarding administration?
A. Take the medication with a full meal to increase absorption.
B. Take the medication at bedtime to prevent daytime drowsiness.
C. Take the medication only when symptoms of fatigue or cold intolerance occur.
D. Take the medication in the morning on an empty stomach, 30-60 minutes before
breakfast.
Correct Answer: D
Expert Explanation: Levothyroxine is best absorbed when taken on an empty stomach in
the early morning. Consistency is key to maintaining stable thyroid hormone levels in the
blood. Taking it with food or other medications can significantly impair its absorption and
efficacy.
, 4. A patient with Addison’s disease is taking Fludrocortisone. What clinical finding should the
nurse prioritize as a potential adverse effect?
A. Hypotension and weight loss.
B. Hypokalemia and peripheral edema.
C. Hyperkalemia and dehydration.
D. Hypoglycemia and increased skin pigmentation.
Correct Answer: B
Expert Explanation: Fludrocortisone is a mineralocorticoid that causes the body to retain
sodium and water while excreting potassium. Excessive levels can lead to fluid volume
overload, edema, and low potassium levels. Nurses must monitor blood pressure and
electrolyte levels closely during therapy.
5. A patient is receiving Propylthiouracil (PTU) for Hyperthyroidism. Which laboratory result
should the nurse monitor most closely for serious toxicity?
A. Serum Calcium levels.
B. Liver function tests (ALT/AST).
C. Blood Urea Nitrogen (BUN).
D. Serum Sodium levels.
Correct Answer: B
