FPGEE Trivia FPGEE Exam 5 — Questions and Answers
Question 1: What is the first-line treatment for community-acquired pneumonia in a healthy outpatient adult with no comorbidities?
- Levofloxacin
- Azithromycin or doxycycline (Correct answer)
- Amoxicillin-clavulanate
- IV ceftriaxone
Correct answer: Azithromycin or doxycycline
IDSA/ATS guidelines recommend azithromycin or doxycycline as first-line for healthy outpatients with CAP.
Question 2: Which drug class is associated with causing Stevens-Johnson syndrome as a serious adverse effect?
- ACE inhibitors
- Beta-blockers
- Sulfonamide antibiotics (Correct answer)
- Loop diuretics
Correct answer: Sulfonamide antibiotics
Sulfonamide antibiotics (e.g., trimethoprim-sulfamethoxazole) are classically associated with Stevens-Johnson syndrome.
Question 3: What is the clinical significance of a drug with a narrow therapeutic index?
- The drug has very few side effects
- Small dosage changes can lead to toxicity or subtherapeutic levels (Correct answer)
- The drug is only available in one dosage form
- The drug has no known drug interactions
Correct answer: Small dosage changes can lead to toxicity or subtherapeutic levels
Narrow therapeutic index drugs require close monitoring because the toxic dose is close to the therapeutic dose.
Question 4: Which type of drug interaction occurs when one drug alters the renal tubular secretion of another?
- Pharmacodynamic interaction
- Pharmacokinetic-distribution interaction
- Pharmacokinetic-excretion interaction (Correct answer)
- Receptor-mediated interaction
Correct answer: Pharmacokinetic-excretion interaction
Alterations in renal tubular secretion represent a pharmacokinetic interaction at the excretion stage.
Question 5: What is the primary difference between bacteriostatic and bactericidal antibiotics?
- Bacteriostatic drugs kill bacteria; bactericidal drugs slow their growth
- Bacteriostatic drugs inhibit growth; bactericidal drugs kill bacteria (Correct answer)
- Bacteriostatic drugs have fewer side effects than bactericidal drugs
- Bactericidal drugs require longer treatment courses
Correct answer: Bacteriostatic drugs inhibit growth; bactericidal drugs kill bacteria
Bacteriostatic agents inhibit bacterial growth (relying on host immunity) while bactericidal agents directly kill bacteria.
Question 6: A patient with renal impairment requires dose adjustment. Which pharmacokinetic parameter is most relevant to assess?
- Volume of distribution
- Protein binding
- Renal clearance (Correct answer)
- Hepatic first-pass metabolism
Correct answer: Renal clearance
Renal clearance directly determines how much drug is eliminated by the kidneys, requiring adjustment in renal impairment.
Question 7: Which of the following is the correct definition of therapeutic equivalence?
- Two drugs with the same chemical structure
- Two drug products that produce the same clinical effect and safety profile (Correct answer)
- Two drugs with identical bioavailability
- Two drugs approved for the same indication
Correct answer: Two drug products that produce the same clinical effect and safety profile
Therapeutic equivalence means two drug products produce the same clinical effect and safety when administered under the same conditions.
