A 61-year-old man presents with thickened toenails. Keratin and debris have accumulated distally and underneath, and the nail has separated from the nail bed. Which of the following is most consistent with this clinical scenario?
Pseudomonas
Onychomycosis
Herpetic whitlow
Parasitic infection
The Correct Answer is B
Choice A reason: Pseudomonas infections can cause green discoloration of nails, but do not typically cause thickening with distal subungual keratin accumulation as described.
Choice B reason: Onychomycosis is a fungal nail infection characterized by thickening, debris accumulation under the nail, and onycholysis (nail separation from the bed), matching the patient’s clinical presentation.
Choice C reason: Herpetic whitlow is a viral infection of the finger or toe causing painful vesicles, not thickened nails with subungual debris.
Choice D reason: Parasitic infections rarely affect nails in this manner and do not produce the chronic thickening and keratin buildup observed in onychomycosis.

Correct Answer is B
Explanation
Choice A reason: Social learning involves modeling behavior and reinforcement, not eliciting self-reflection on behavior.
Choice B reason: This is correct. Motivational interviewing uses open-ended questions, reflective listening, and strategic prompts to help clients recognize discrepancies between their current behavior and long-term goals, promoting intrinsic motivation to change.
Choice C reason: Person-centered therapy emphasizes empathy, unconditional positive regard, and client self-exploration, not direct elicitation of ambivalence.
Choice D reason: Transactional analysis focuses on interpersonal communication and ego states, not targeted behavioral change through motivational questioning.
Correct Answer is B
Explanation
Choice A reason: Pneumonia presents with infection-related symptoms and radiographic changes, not reversible airway obstruction or hyperreactivity.
Choice B reason: Correct. Asthma is characterized by reversible airway obstruction, bronchial hyperreactivity, inflammation, and structural changes like smooth muscle hypertrophy, which matches this clinical picture.
Choice C reason: Bronchitis involves inflammation of the bronchi, often due to infection, and does not typically produce reversible airway obstruction or chronic airway changes.
Choice D reason: Sinusitis affects the sinuses, not the lower airways, and would not account for wheezing or bronchial hyperreactivity.
