Correct Answers and Expert Explanation for Each
Question | Chamberlain
1. A patient with chronic liver disease has a low serum albumin level. How does this
affect the pharmacokinetics of highly protein-bound drugs?
A. Increased protein binding
B. Decreased volume of distribution
C. Increased free drug concentration
D. Decreased rate of absorption
Correct Answer: C
Expert Explanation: Low albumin levels result in fewer binding sites for
medications that normally attach to plasma proteins. This leads to a higher
percentage of the drug being in its free or active state within the systemic
circulation. Clinicians must monitor these patients closely to prevent toxicity even
when total drug levels appear normal.
2. Which mechanism explains why ACE inhibitors often cause a persistent, dry cough?
A. Increased levels of aldosterone
B. Accumulation of bradykinin
,C. Direct irritation of the bronchial mucosa
D. Inhibition of surfactant production
Correct Answer: B
Expert Explanation: ACE inhibitors block the enzyme that converts angiotensin I to
angiotensin II, but this same enzyme also breaks down bradykinin. When the
enzyme is inhibited, bradykinin levels rise in the lungs, which can trigger a dry,
hacking cough. This is a common class-specific side effect that often necessitates a
switch to an Angiotensin Receptor Blocker (ARB).
3. What is the most significant contraindication for the use of Metformin in patients
with Type 2 Diabetes?
A. History of mild hypertension
B. Body mass index over 30
C. Severe renal impairment (eGFR < 30)
D. Age over 65 years
Correct Answer: C
Expert Explanation: Metformin is primarily excreted by the kidneys and can
accumulate in the setting of renal failure. Elevated metformin levels increase the
risk of lactic acidosis, a rare but potentially life-threatening metabolic complication.
,Current guidelines state that Metformin is contraindicated in patients with an eGFR
below 30 mL/min/1.73m2.
4. A patient is prescribed Levothyroxine for hypothyroidism. What is the most
important administration instruction to provide?
A. Take with a large meal to improve absorption
B. Take at bedtime with a glass of milk
C. Take on an empty stomach 30-60 minutes before breakfast
D. Take only when feeling symptomatic (fatigue or cold)
Correct Answer: C
Expert Explanation: Levothyroxine absorption is highly sensitive to the presence
of food and other medications in the stomach. For optimal and consistent
absorption, it should be taken first thing in the morning on an empty stomach with a
full glass of water. Patients should wait at least 30 to 60 minutes before consuming
food or other medications.
5. A patient on Warfarin therapy is counseled about their diet. Which statement by
the patient indicates a correct understanding?
A. I will keep my intake of green leafy vegetables consistent
B. I will avoid all green leafy vegetables entirely
, C. I will eat extra spinach if I notice bruising
D. I will only eat Vitamin K-rich foods once a week
Correct Answer: A
Expert Explanation: Warfarin works by antagonizing Vitamin K, so significant
changes in Vitamin K intake can alter the drug’s effectiveness. Rather than avoiding
green leafy vegetables, patients should maintain a consistent intake to allow for
stable dosing and INR levels. Sudden increases in Vitamin K can decrease the INR,
while sudden decreases can increase the risk of bleeding.
6. Which of the following is considered first-line treatment for an otherwise healthy
child with acute otitis media?
A. Azithromycin
B. Amoxicillin
C. Ciprofloxacin
D. Cephalexin
Correct Answer: B
Expert Explanation: Amoxicillin remains the first-line choice for pediatric acute
otitis media due to its effectiveness against common pathogens like Streptococcus
pneumoniae. It is preferred because of its narrow spectrum, safety profile, and low
