NPTE-PT MCQ 4 — Questions and Answers
Question 1: A child is unable to isolate finger movements and displays primitive grasp reflexes at age 18 months. This suggests impairment in which developmental progression?
- Gross motor milestones
- Cortical differentiation and fine motor control (Correct answer)
- Visual tracking
- Postural righting reactions
Correct answer: Cortical differentiation and fine motor control
Isolated finger movements and release of primitive reflexes depend on cortical maturation; persistence at 18 months indicates delayed fine motor cortical differentiation.
Question 2: Which special test is MOST specific for a supraspinatus tendon tear?
- Speed's test
- Neer impingement sign
- Drop arm test (Correct answer)
- Yergason's test
Correct answer: Drop arm test
The drop arm test has high specificity for a full-thickness supraspinatus tear, as the patient cannot slowly lower the arm from 90° abduction.
Question 3: A PT documents passive ROM as 'WFL.' This abbreviation means:
- Within functional limits (Correct answer)
- Within full length
- Without functional loss
- Without force loading
Correct answer: Within functional limits
WFL stands for 'within functional limits,' indicating ROM is sufficient for the patient's functional needs even if not full normal ROM.
Question 4: During stair descent, the knee experiences maximum stress at approximately what degree of flexion?
- 0–10°
- 30–45° (Correct answer)
- 60–75°
- 90–100°
Correct answer: 30–45°
Patellofemoral and tibiofemoral joint stress peaks around 30–45° of knee flexion during the loading response of stair descent.
Question 5: Which stage of pressure injury involves full-thickness skin and tissue loss with visible or palpable fascia, muscle, tendon, ligament, or bone?
- Stage 2
- Stage 3
- Stage 4 (Correct answer)
- Unstageable
Correct answer: Stage 4
Stage 4 pressure injuries involve full-thickness tissue loss exposing deep structures such as fascia, muscle, tendon, or bone.
Question 6: A patient is referred for cardiac rehabilitation after CABG surgery. At what METs level is most ADL activity (e.g., self-care, slow walking) performed?
- 1–2 METs
- 2–3 METs (Correct answer)
- 4–5 METs
- 6–7 METs
Correct answer: 2–3 METs
Basic ADLs and slow ambulation require approximately 2–3 METs, which is the target activity level for early Phase I cardiac rehabilitation.
Question 7: The H-reflex is the electrophysiological equivalent of which clinical reflex?
- Patellar reflex (L3–L4)
- Achilles reflex (S1–S2) (Correct answer)
- Biceps reflex (C5–C6)
- Babinski reflex
Correct answer: Achilles reflex (S1–S2)
The H-reflex tests the S1 monosynaptic arc via stimulation of Ia afferents in the tibial nerve, equivalent to the Achilles deep tendon reflex.
