1. A nurse is preparing to administer insulin lispro to a patient. When should the nurse
provide this medication?
A. 30 to 60 minutes before a meal
B. 15 minutes before a meal
C. Immediately after a meal
D. At bedtime with a snack
Correct Answer: B
Expert Explanation: Insulin lispro is a rapid-acting insulin with a very quick onset of
action. It should be administered within 15 minutes of a meal to prevent hypoglycemia. The
nurse must ensure that the patient’s food tray is present before giving the injection.
2. Which medication is considered the first-line oral treatment for Type 2 Diabetes Mellitus?
A. Glipizide
B. Acarbose
C. Pioglitazone
D. Metformin
Correct Answer: D
,Expert Explanation: Metformin is the initial drug of choice for Type 2 Diabetes because it
decreases glucose production by the liver. It does not cause hypoglycemia when used alone
and is often associated with weight loss. Patients must be monitored for gastrointestinal
side effects and lactic acidosis.
3. A patient is prescribed levothyroxine for hypothyroidism. Which instruction should the
nurse include in the teaching?
A. Take the medication with a full dinner.
B. Take the medication on an empty stomach in the morning.
C. Stop the medication if you feel energetic.
D. Take the medication only when symptoms occur.
Correct Answer: B
Expert Explanation: Levothyroxine should be taken consistently in the morning 30 to 60
minutes before breakfast to ensure optimal absorption. Taking it with food can decrease its
bioavailability and effectiveness. It is a lifelong therapy that should not be stopped abruptly
without medical supervision.
4. What is the primary mechanism of action for the drug Albuterol?
A. Reducing inflammation in the airways
B. Stimulating beta-2 receptors to cause bronchodilation
C. Blocking histamine receptors
, D. Liquefying thick mucus secretions
Correct Answer: B
Expert Explanation: Albuterol is a short-acting beta-2 agonist (SABA) used as a rescue
inhaler for acute asthma symptoms. It works by relaxing the smooth muscles of the
bronchi, leading to rapid bronchodilation. Side effects may include tachycardia, tremors,
and anxiety due to its sympathomimetic effects.
5. A patient is taking Prednisone for a chronic inflammatory condition. Which side effect is a
major concern with long-term use?
A. Osteoporosis
B. Hypoglycemia
C. Weight loss
D. Hypotension
Correct Answer: A
Expert Explanation: Long-term glucocorticoid use like Prednisone can lead to significant
bone density loss and osteoporosis. It also causes hyperglycemia, weight gain, and
increased risk of infection. Patients should be taught to never stop the medication suddenly
to avoid adrenal crisis.
6. Which of the following medications is a Proton Pump Inhibitor (PPI) used for GERD?
A. Famotidine
