1. A nurse is preparing to administer insulin glargine to a patient with type 1 diabetes. Which
statement by the nurse is correct regarding the administration of this medication?
A. This insulin should be mixed with regular insulin in the same syringe.
B. This insulin has a peak action time of 2 to 4 hours.
C. This insulin is typically administered once daily at the same time.
D. This insulin is only given intravenously during emergencies.
Correct Answer: C
Expert Explanation: Insulin glargine is a long-acting insulin that provides a steady level of
insulin over 24 hours. It lacks a peak action time, which helps reduce the risk of
hypoglycemia. It must never be mixed in the same syringe with any other types of insulin.
2. A patient is prescribed metformin for type 2 diabetes. Which laboratory result would be
the most significant concern for the nurse?
A. Increased serum potassium
B. Slightly elevated blood glucose
C. Decreased hemoglobin A1c
D. Elevated serum creatinine
,Correct Answer: D
Expert Explanation: Metformin is primarily excreted by the kidneys, and impaired renal
function increases the risk of lactic acidosis. An elevated serum creatinine indicates
potential renal impairment. The nurse must monitor kidney function closely while the
patient is on this therapy.
3. The nurse is teaching a patient about using an albuterol inhaler. What side effect should
the nurse emphasize?
A. Drowsiness
B. Bradycardia
C. Tachycardia
D. Increased appetite
Correct Answer: C
Expert Explanation: Albuterol is a short-acting beta-2 agonist that can stimulate the heart,
leading to tachycardia and tremors. Patients should be taught to monitor their pulse and
report significant increases to their provider. It is used as a rescue medication for acute
bronchospasm.
4. A patient is prescribed beclomethasone dipropionate by inhalation. What instruction is
essential for the nurse to provide?
A. Use this medication only when you feel short of breath.
B. Rinse your mouth with water after each use.
, C. Take a double dose if you miss a scheduled time.
D. Limit fluid intake to 1 liter per day.
Correct Answer: B
Expert Explanation: Inhaled corticosteroids like beclomethasone can cause oral
candidiasis, also known as thrush. Rinsing the mouth after administration helps prevent
fungal overgrowth in the oral cavity. This medication is for maintenance and is not used for
acute asthma attacks.
5. A patient is receiving levothyroxine for hypothyroidism. When should the nurse instruct
the patient to take this medication?
A. Right before bedtime with a snack
B. In the morning, 30 to 60 minutes before breakfast
C. Immediately following the evening meal
D. With a glass of milk at lunchtime
Correct Answer: B
Expert Explanation: Levothyroxine should be taken on an empty stomach to ensure
optimal absorption. Taking it in the morning also helps prevent insomnia, which can occur
if taken later in the day. It is important to wait at least 30 to 60 minutes before consuming
food or other medications.
