A technically valid DXA report for a 68-year-old postmenopausal woman lists a femoral-neck T-score of -2.8 and a lumbar-spine T-score of -1.6. She has no known fragility fracture. How should these findings be classified?
Correct answer: A - Osteoporosis, based on the femoral-neck T-score
The pre-splint note for a child with a supracondylar humerus fracture reads, "Fingers move; fingertip sensation intact." That description does not establish anterior interosseous nerve function. Which additional maneuver tests that branch most directly?
Correct answer: A - Form a tip-to-tip circle by bending the thumb and index-finger tip joints
While turning out of a deep squat, a worker feels a catch in the medial knee. The knee now stops short of full extension. The clinician documents medial joint-line tenderness and a firm mechanical block rather than pain-limited movement; cruciate testing is symmetric with the uninjured knee. What lesion most likely produces this block?
Correct answer: B - Displaced medial meniscal tear
When distinguishing rheumatoid arthritis from osteoarthritis, which finding most strongly favors rheumatoid arthritis?
Correct answer: D - Symmetric swelling of the metacarpophalangeal joints with prolonged morning stiffness
A 14-year-old has limped for three weeks because of poorly localized knee pain. There is no knee effusion or focal knee tenderness. During the clinician's hip examination, internal rotation is restricted and the thigh turns outward as the hip is flexed. Which diagnosis best accounts for the apparent knee complaint?
Correct answer: D - Slipped capital femoral epiphysis
The parents of a 6-year-old request corrective devices for flat feet. Both arches reappear on tiptoe, ankle motion is unrestricted, and the child runs and jumps without pain. The clinician confirms painless flexible flatfoot. Which advice should be reinforced?
Correct answer: C - Continue comfortable activity; no corrective device is needed
Two hours after a tibial fracture is placed in a circumferential cast, pain is increasing despite prescribed analgesia. Passive toe extension causes marked pain, and the patient reports new tingling. The toes remain warm with palpable distal pulses. What takes priority?
Correct answer: D - Activate emergency orthopedic review and release the cast and constricting padding under the emergency protocol
Following reduction of a distal radius fracture, the clinician requests temporary immobilization that limits pronation and supination while accommodating expected swelling. Which device meets both requirements?
Correct answer: C - A sugar-tong splint
An assistant preparing a plaster lower-leg splint plans to rest the freshly applied splint on a foam pillow and cover it with a folded blanket while it hardens. The prescribed limb position and plaster thickness are appropriate. Which change addresses the thermal hazard in this setup?
Correct answer: B - Leave the supported splint uncovered with air circulating around it
An 84-kg adult has an order limiting the injured leg to 25% of body weight. During supervised static loading practice with correctly fitted crutches, a calibrated scale beneath the injured foot reads 28 kg. The other foot is supported at the same height; balance is steady and there are no new symptoms. Which instruction applies the order correctly?
Correct answer: A - Shift weight to the crutches, reducing the injured-foot reading to 21 kg or less
