Correct Answers and Expert Explanation for Each
Question | Chamberlain
1. A 62-year-old male with a history of heart failure is prescribed Lisinopril. Which of
the following lab values is most important to monitor after initiating this therapy?
A. Serum Sodium
B. Serum Magnesium
C. Serum Potassium
D. Serum Calcium
Correct Answer: C
Expert Explanation: ACE inhibitors like Lisinopril interfere with the renin-
angiotensin-aldosterone system, leading to decreased aldosterone secretion. This
reduction in aldosterone can cause the kidneys to retain potassium, potentially
leading to hyperkalemia. Regular monitoring of serum potassium is essential to
prevent cardiac arrhythmias associated with high levels.
2. A patient taking Simvastatin for hyperlipidemia reports new-onset muscle pain and
weakness. What is the most appropriate next step for the provider?
A. Increase the dose to provide better therapeutic effect
,B. Order a Creatine Kinase (CK) level and evaluate for myopathy
C. Switch the patient to a different statin immediately
D. Tell the patient to take the medication with a glass of grapefruit juice
Correct Answer: B
Expert Explanation: Statins are known to cause muscle-related side effects ranging
from mild myalgias to life-threatening rhabdomyolysis. Obtaining a Creatine Kinase
level helps the clinician assess the degree of muscle damage. Grapefruit juice
actually increases the risk of toxicity by inhibiting the CYP3A4 enzyme responsible
for statin metabolism.
3. Which of the following is a Black Box Warning associated with the use of
Fluoroquinolones like Ciprofloxacin?
A. Severe Hepatotoxicity
B. Risk of Tendon Rupture
C. Stevens-Johnson Syndrome
D. Acute Renal Failure
Correct Answer: B
Expert Explanation: Fluoroquinolones carry a significant Black Box Warning
regarding the increased risk of tendinitis and tendon rupture in all ages. This risk is
,further increased in patients over 60, those taking corticosteroids, and
kidney/heart/lung transplant recipients. Patients should be advised to stop the drug
and contact their provider if they experience tendon pain or inflammation.
4. A patient with Type 2 Diabetes is being started on Metformin. Which underlying
condition is a contraindication for this medication?
A. Hypertension
B. Severe Renal Impairment (eGFR < 30)
C. Glaucoma
D. Hypothyroidism
Correct Answer: B
Expert Explanation: Metformin is primarily excreted by the kidneys and can
accumulate in the setting of renal failure. Accumulation of Metformin increases the
risk of lactic acidosis, which is a rare but potentially fatal metabolic complication.
According to current guidelines, Metformin is contraindicated in patients with an
eGFR below 30 mL/min/1.73 m2.
5. When counseling a patient on the use of Warfarin, which of the following dietary
instructions is most accurate?
A. Avoid all green leafy vegetables entirely
B. Only eat Vitamin K foods once a week
, C. Increase Vitamin K intake to improve the drug’s effectiveness
D. Maintain a consistent intake of Vitamin K-rich foods
Correct Answer: D
Expert Explanation: Warfarin works by inhibiting Vitamin K-dependent clotting
factors, so sudden changes in Vitamin K intake can drastically affect the INR.
Patients do not need to avoid green leafy vegetables but must keep their
consumption consistent so the dose can be adjusted accordingly. Fluctuations in
Vitamin K intake can lead to either subtherapeutic levels (increasing clot risk) or
supratherapeutic levels (increasing bleeding risk).
6. A patient is diagnosed with community-acquired pneumonia and has no comorbid
conditions. Which antibiotic is typically recommended as first-line therapy?
A. Vancomycin
B. Ciprofloxacin
C. Amoxicillin or Doxycycline
D. Gentamicin
Correct Answer: C
Expert Explanation: For healthy outpatients with community-acquired pneumonia
and no risk factors for MRSA or Pseudomonas, Amoxicillin or Doxycycline are often
