3P Comprehensive Practice Examination (70 Questions with Explanatory Rationales)
Question 1
During a physical examination of the thorax, the advanced practice registered nurse (APRN) performs
chest percussion and identifies a hyperresonant note over the left chest field. Which of the following
conditions is most consistent with this finding?
A) Lobar pneumonia
B) Pleural effusion
C) Pneumothorax
B) Pulmonary fibrosis
Correct Answer: C) Pneumothorax
Rationale: Hyperresonance on percussion indicates excessive air within the pleural space or lung parenchyma.
Common causes include pneumothorax, severe asthma, or emphysema. Conversely, lobar pneumonia, pleural
effusion, and pulmonary fibrosis produce dullness on percussion due to fluid, consolidation, or tissue density.
Question 2
A 45-year-old female presents with fatigue, cold intolerance, weight gain, and dry skin. On physical
exam, the APRN notes delayed relaxation phase of deep tendon reflexes (brisk phase, delayed return).
Which test is the most sensitive initial diagnostic evaluation?
A) Serum Free T4
B) Thyroid-Stimulating Hormone (TSH)
C) Anti-thyroid peroxidase antibodies
D) Serum Total T3
Correct Answer: B) Thyroid-Stimulating Hormone (TSH)
Rationale: Serum TSH is the most sensitive screening test for primary hypothyroidism. Delayed relaxation
phase of deep tendon reflexes (hung-up reflexes) is a classic sign of hypothyroidism. Free T4 is measured
secondarily or concurrently to confirm primary vs. secondary etiology.
, Question 3
When evaluating a patient for potential meniscal injury of the knee, which clinical physical
assessment maneuver is considered most specific?
A) Anterior drawer test
B) Lachman test
C) McMurray test
D) Valgus stress test
Correct Answer: C) McMurray test
Rationale: The McMurray test (medial/lateral rotation with knee extension) evaluates for meniscal tears. A
positive test produces a palpable or audible click/pop with joint line pain. The anterior drawer and Lachman
tests assess the anterior cruciate ligament (ACL), while the valgus stress test evaluates the medial collateral
ligament (MCL).
Question 4
An 8-year-old child presents with a high fever, severe sore throat, drooling, and a muffled 'hot potato'
voice. The child is sitting upright and leaning forward with hands on knees. What is the immediate
priority of management?
A) Perform a vigorous direct throat examination with a tongue depressor
B) Obtain a rapid strep swab and throat culture immediately
C) Airway stabilization and emergent ENT/anesthesia consultation
D) Administer high-dose oral amoxicillin in the office
Correct Answer: C) Airway stabilization and emergent ENT/anesthesia consultation
Rationale: This presentation is classic for acute epiglottitis (tripod positioning, drooling, muffled voice, fever).
Direct visualization of the pharynx with a tongue depressor or invasive procedures should be strictly avoided
in an un-intubated child because it can precipitate complete upper airway laryngospasm and total obstruction.
Emergent airway management in a controlled environment is mandatory.
Question 5
During a funduscopic examination, the APRN visualizes microaneurysms, hard exudates, cotton wool
spots, and flame-shaped hemorrhages. These findings are most characteristic of which condition?
A) Hypertensive retinopathy
B) Diabetic retinopathy
C) Open-angle glaucoma
D) Age-related macular degeneration
Correct Answer: B) Diabetic retinopathy
Rationale: Microaneurysms are the earliest sign of diabetic retinopathy, followed by hard exudates (lipid
