Questions & Verified Answers
1. A 45-year-old male presents with a sudden onset of painful, red, and swollen great toe. Which
of the following is the most likely diagnosis?
A. Rheumatoid arthritis
B. Septic arthritis
C. Osteoarthritis
D. Gouty arthritis
Answer: D
Rationale: Gouty arthritis typically presents as an acute, severe onset of pain, redness, and swelling in the first
metatarsophalangeal joint (podagra). Recognizing this principle allows the nurse to prioritize care, anticipate
complications, and provide accurate patient education. Exam questions often test the ability to distinguish this
concept from closely related distractors, making a clear rationale essential for mastery.
2. Using the Centor criteria, which of the following patients is most likely to have Group A
Beta-Hemolytic Streptococcal (GABHS) pharyngitis?
A. A patient with cough, rhinorrhea, and low-grade fever
B. A patient with sandpaper-like rash and abdominal pain
C. A patient with posterior cervical lymphadenopathy and fatigue
D. A patient with tonsillar exudates, tender anterior cervical lymphadenopathy, and absence of cough
Answer: D
Rationale: The Centor criteria include fever, tonsillar exudates, tender anterior cervical lymphadenopathy, and
the absence of cough to estimate the probability of GABHS. Recognizing this principle allows the nurse to
prioritize care, anticipate complications, and provide accurate patient education. Exam questions often test the
ability to distinguish this concept from closely related distractors, making a clear rationale essential for mastery.
3. A patient presents with a ‘honey-colored’ crusted lesion on the perioral area. What is the
most appropriate first-line treatment?
A. Oral Amoxicillin
B. Oral Acyclovir
C. Topical Mupirocin (Bactroban)
D. Topical Hydrocortisone
Answer: C
Rationale: The description fits Impetigo, for which topical Mupirocin is the first-line treatment for localized
lesions. Exam questions often test the ability to distinguish this concept from closely related distractors, making
a clear rationale essential for mastery. Applying this knowledge in clinical settings supports safe,
evidence-based practice and improves patient outcomes.

4. According to the GOLD criteria, which of the following is required to confirm a diagnosis of
COPD?
A. Chest X-ray showing hyperinflation
B. Total lung capacity > 120%
C. Post-bronchodilator FEV1/FVC < 0.70
D. Pulse oximetry < 92% on room air
Answer: C
Rationale: A post-bronchodilator FEV1/FVC ratio of less than 0.70 confirms the presence of persistent airflow
limitation, diagnostic of COPD. Exam questions often test the ability to distinguish this concept from closely
related distractors, making a clear rationale essential for mastery. Applying this knowledge in clinical settings
supports safe, evidence-based practice and improves patient outcomes.
5. Which of the following is a classic physical exam finding for a patient with acute otitis
externa?
A. Pain with tragal pressure or pinna traction
B. Bulging of the tympanic membrane
C. Loss of bony landmarks on the TM
D. Fluid behind the tympanic membrane
Answer: A
Rationale: Pain when pulling on the pinna or pushing on the tragus is a hallmark sign of otitis externa
(swimmer’s ear). Recognizing this principle allows the nurse to prioritize care, anticipate complications, and
provide accurate patient education. Exam questions often test the ability to distinguish this concept from closely
related distractors, making a clear rationale essential for mastery.
6. A 24-year-old female presents with symptoms of a UTI. The urine dipstick is positive for
nitrites. What does this specifically indicate?
A. Inflammation of the bladder wall
B. Presence of Gram-negative bacteria like E. coli
C. Contamination of the sample
D. Renal calculi
Answer: B
Rationale: Nitrites are produced when certain bacteria, most commonly Gram-negative organisms like E. coli,
reduce nitrates to nitrites. This is an important clinical concept because selecting the correct answer (B)
requires understanding both the pathophysiology and the practical nursing implications. Recognizing this
principle allows the nurse to prioritize care, anticipate complications, and provide accurate patient education.
