1. A nurse is providing education to a patient newly prescribed Levothyroxine for
hypothyroidism. Which instruction is most critical for the patient to follow regarding
administration?
A. Take the medication with a full meal to enhance absorption.
B. Take the medication on an empty stomach, 30 to 60 minutes before breakfast.
C. Take the medication at bedtime with a glass of milk.
D. Double the dose if a single dose is accidentally missed.
Correct Answer: B
Explanation: Levothyroxine absorption is significantly decreased when taken with food or
certain minerals like calcium. Patients should be instructed to take it in the morning on an
empty stomach to ensure consistent blood levels. They should wait at least 30 to 60
minutes before eating or drinking anything other than water.
2. A patient with Type 1 Diabetes is prescribed Insulin Lispro (Humalog). The nurse should
teach the patient to administer this insulin at what time?
A. 60 minutes before a meal.
B. 15 minutes before or immediately with a meal.
,C. Only when blood glucose is above 200 mg/dL.
D. Once daily at bedtime.
Correct Answer: B
Explanation: Insulin Lispro is a rapid-acting insulin with an onset of action between 15 to
30 minutes. Administering it too early without food present can lead to severe
hypoglycemia. The nurse must emphasize that the patient should have their meal ready to
consume immediately after injection.
3. A nurse is caring for a patient receiving long-term Prednisone therapy for an autoimmune
condition. Which laboratory value should the nurse monitor most closely?
A. Serum Magnesium
B. Serum Glucose
C. Serum Hemoglobin
D. Serum Bicarbonate
Correct Answer: B
Explanation: Corticosteroids like Prednisone commonly cause hyperglycemia by
increasing gluconeogenesis and decreasing glucose uptake in the tissues. This is especially
important for patients with underlying diabetes, as they may require adjusted insulin
doses. Long-term use also necessitates monitoring for electrolyte imbalances and
osteoporosis.
, 4. Which statement by a patient prescribed Omeprazole (Prilosec) indicates a need for further
teaching?
A. “I will stop taking this medication as soon as my heartburn goes away.”
B. “I should take this medication before I eat breakfast.”
C. “I need to swallow the capsule whole and not crush it.”
D. “I should report any severe diarrhea to my healthcare provider.”
Correct Answer: A
Explanation: Proton Pump Inhibitors (PPIs) like Omeprazole should be taken for the full
duration prescribed to allow for proper tissue healing. Stopping the medication abruptly
can lead to a return of symptoms or incomplete healing of an ulcer. Additionally, long-term
use is associated with risks like C. difficile infections and bone fractures.
5. A patient is scheduled for a CT scan with intravenous contrast and is currently taking
Metformin (Glucophage). What action should the nurse take?
A. Administer the Metformin as scheduled before the procedure.
B. Hold the Metformin for 48 hours before and after the procedure.
C. Instruct the patient to double the dose after the procedure.
D. Give the Metformin with a large glass of grapefruit juice.
Correct Answer: B
