MCQ Flashcards

A child is unable to isolate finger movements and displays primitive grasp reflexes at age 18 months. This suggests impairment in which developmental progression?

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.

Which special test is MOST specific for a supraspinatus tendon tear?

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.

A PT documents passive ROM as 'WFL.' This abbreviation means:

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.

During stair descent, the knee experiences maximum stress at approximately what degree of flexion?

Answer: 30–45°

Patellofemoral and tibiofemoral joint stress peaks around 30–45° of knee flexion during the loading response of stair descent.

Which stage of pressure injury involves full-thickness skin and tissue loss with visible or palpable fascia, muscle, tendon, ligament, or bone?

Answer: Stage 4

Stage 4 pressure injuries involve full-thickness tissue loss exposing deep structures such as fascia, muscle, tendon, or bone.

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?

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.

The H-reflex is the electrophysiological equivalent of which clinical reflex?

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.
