Answer: A
Rationale: The Centor criteria for Strep throat include fever, tonsillar exudates, tender anterior cervical
lymphadenopathy, and the absence of cough. 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. What is the first-line topical treatment for a patient diagnosed with uncomplicated Otitis
Externa?
A. Ciprofloxacin and dexamethasone otic drops
B. Oral Amoxicillin
C. Fluconazole solution
D. Nystatin powder
Answer: A
Rationale: Topical fluoroquinolones, often combined with a corticosteroid like dexamethasone, are the

B. FEV1/FVC ratio < 0.7
C. FVC > 90% predicted
D. FEV1 increase of 5% post-albuterol

limitation, diagnostic of COPD. 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.
5. A patient presents with a ring-shaped, erythematous lesion with central clearing and a scaly
border. What is the most likely diagnosis?
A. Cellulitis
B. Psoriasis
C. Eczema
D. Tinea corporis
Answer: D
Rationale: Tinea corporis, or ringworm, typically presents as an annular (ring-like) lesion with a raised, scaly
border and central clearing. This is an important clinical concept because selecting the correct answer (D)
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.
6. Which clinical feature is characteristic of a Scabies infestation?
A. Painless yellow pustules
B. Large silver-white plaques

linear burrows in skin folds. Applying this knowledge in clinical settings supports safe, evidence-based practice
and improves patient outcomes. This is an important clinical concept because selecting the correct answer (C)
requires understanding both the pathophysiology and the practical nursing implications.
