Correct Answers and Expert Explanation for Each

1. Which of the following is the most common reason for discontinuing Metformin
therapy in patients with type 2 diabetes?
A. Peripheral edema
B. Weight gain
C. Hyperglycemia
D. Gastrointestinal distress
Correct Answer: D
Expert Explanation: Metformin is known to cause significant gastrointestinal side
effects such as diarrhea, nausea, and abdominal cramping. These symptoms usually
occur at the start of therapy or when the dose is increased. Starting with a low dose
and taking the medication with food can help mitigate these effects.
2. A patient is prescribed Levothyroxine for hypothyroidism. What is the most
important instruction regarding administration?
A. Take it on an empty stomach 30 to 60 minutes before breakfast
B. Take it at bedtime with a glass of milk
,C. Take it with a large meal to increase absorption
D. Take it only when symptoms of fatigue are present
Correct Answer: A
Expert Explanation: Levothyroxine absorption is significantly reduced when taken
with food, certain minerals, or other medications. Patients should be instructed to
take it in the morning on an empty stomach with a full glass of water. Maintaining a
consistent routine is essential for stabilizing thyroid-stimulating hormone levels.
3. Fluoroquinolones, such as Ciprofloxacin, carry a Black Box Warning for which of the
following risks?
A. Acute liver failure
B. Severe hypoglycemia
C. Tendon rupture and tendinitis
D. Stevens-Johnson syndrome
Correct Answer: C
Expert Explanation: Fluoroquinolones are associated with an increased risk of
tendinitis and tendon rupture, particularly the Achilles tendon. This risk is higher in
elderly patients, those taking corticosteroids, and transplant recipients. Patients
,should be advised to stop the medication and contact their provider if they
experience any tendon pain or inflammation.
4. What is the primary mechanism of action for ACE inhibitors in the treatment of
hypertension?
A. Directly inhibiting renin release
B. Blocking the conversion of Angiotensin I to Angiotensin II
C. Blocking Angiotensin II receptors
D. Increasing the excretion of potassium
Correct Answer: B
Expert Explanation: ACE inhibitors work by inhibiting the angiotensin-converting
enzyme, which prevents the conversion of Angiotensin I into the potent
vasoconstrictor Angiotensin II. This leads to vasodilation and reduced peripheral
resistance. Additionally, it decreases aldosterone secretion, which helps lower blood
pressure through reduced sodium retention.
5. For a patient with non-valvular atrial fibrillation, what is the standard therapeutic
INR range when taking Warfarin?
A. 2.0 to 3.0
B. 1.0 to 2.0
, C. 3.5 to 4.5
D. 1.5 to 2.5
Correct Answer: A
Expert Explanation: The standard therapeutic range for INR in patients with atrial
fibrillation is 2.0 to 3.0 to prevent stroke while minimizing bleeding risk. If the INR
falls below 2.0, the risk of thromboembolism increases significantly. Conversely, an
INR above 3.0 increases the risk of major bleeding events.
6. Which laboratory test should be monitored regularly in a patient taking a high-
intensity statin?
A. Serum creatinine and BUN
B. Complete blood count
C. Liver function tests (ALT/AST)
D. Serum amylase
Correct Answer: C
Expert Explanation: Statins can occasionally cause hepatotoxicity, although routine
monitoring is no longer as frequent as it once was according to current guidelines.
However, baseline liver function tests should always be obtained before starting
