Correct Answers and Expert Explanation for Each
Question | Chamberlain
1. A patient is started on levothyroxine for primary hypothyroidism. What is the most
appropriate timing for the patient to take this medication?
A. With a large meal to prevent GI upset
B. At bedtime with a glass of milk
C. 30 to 60 minutes before breakfast on an empty stomach
D. Right after exercising in the morning
Correct Answer: C
Expert Explanation: Levothyroxine absorption is significantly decreased when
taken with food or certain minerals like calcium. To ensure consistent absorption
and therapeutic efficacy, it must be taken on an empty stomach, preferably 30 to 60
minutes before breakfast. Patients should also wait several hours before taking
other medications like antacids or iron supplements.
2. When prescribing Metformin for a patient with Type 2 Diabetes, which laboratory
value is most critical to monitor to prevent lactic acidosis?
A. Serum Potassium
,B. Alanine Aminotransferase (ALT)
C. Glomerular Filtration Rate (eGFR)
D. Hemoglobin A1c
Correct Answer: C
Expert Explanation: Metformin is primarily excreted by the kidneys, and its
accumulation can lead to life-threatening lactic acidosis. Current guidelines suggest
that Metformin is contraindicated in patients with an eGFR below 30
mL/min/1.73m2. Healthcare providers must monitor renal function regularly and
adjust or discontinue the dose if kidney function declines.
3. A patient taking Lisinopril develops a persistent, dry, non-productive cough. What is
the mechanism behind this side effect?
A. Increased levels of bradykinin in the lungs
B. Direct irritation of the bronchial mucosa
C. Inhibition of surfactant production
D. Fluid overload causing pulmonary edema
Correct Answer: A
Expert Explanation: ACE inhibitors prevent the breakdown of bradykinin and
substance P, which can accumulate in the respiratory tract. This accumulation
,triggers the cough reflex in approximately 10-20% of patients. Switching the patient
to an Angiotensin II Receptor Blocker (ARB) usually resolves the issue because
ARBs do not affect bradykinin levels.
4. A 65-year-old patient is prescribed Warfarin for atrial fibrillation. Which dietary
education is essential for this patient?
A. Avoid all green leafy vegetables entirely
B. Increase intake of grapefruit juice to boost efficacy
C. Maintain a consistent intake of Vitamin K-rich foods
D. Take a high-dose Vitamin E supplement daily
Correct Answer: C
Expert Explanation: Vitamin K is the direct antagonist to Warfarin’s mechanism of
action. Sudden increases or decreases in Vitamin K intake can cause fluctuations in
the International Normalized Ratio (INR), leading to risks of bleeding or clotting.
Patients should be taught to keep their intake of green leafy vegetables consistent
rather than eliminating them.
5. Which of the following beta-blockers is considered cardio-selective and safer for a
patient with a history of mild asthma?
A. Metoprolol
B. Nadolol
, C. Propranolol
D. Sotalol
Correct Answer: A
Expert Explanation: Metoprolol is a cardioselective beta-1 blocker, meaning it
primarily affects the heart and has less impact on beta-2 receptors in the lungs. Non-
selective beta-blockers like Propranolol can cause bronchoconstriction by blocking
beta-2 receptors, which is dangerous for asthma patients. However, even selective
beta-blockers should be used with caution and at low doses in patients with reactive
airway disease.
6. An adolescent patient is started on an SSRI for depression. What is the most
important ‘Black Box Warning’ the provider must discuss with the family?
A. Risk of permanent weight gain
B. High likelihood of developing Type 2 Diabetes
C. Potential for sudden cardiac arrest
D. Increased risk of suicidal ideation and behavior
Correct Answer: D
Expert Explanation: The FDA has issued a Black Box Warning for all
antidepressants regarding the increased risk of suicidal thoughts and behaviors in
