Pediatric Musculoskeletal Disorders Questions
Question 1 of 5
Guillain Barré syndrome is an autoimmune disorder often considered a postinfectious polyneuropathy involving mainly motor but also sensory and sometimes autonomic nerves. All the following are required in diagnosis EXCEPT
Correct Answer: B
Rationale: Muscle biopsy is not required for GBS diagnosis; CSF (elevated protein), EMG, and nerve studies are more relevant.
Question 2 of 5
Enhancers of nonheme iron absorption are
Correct Answer: A
Rationale: Ascorbic acid (vitamin C) is explicitly listed as an enhancer of nonheme iron absorption in the text, making A the primary correct choice.
Question 3 of 5
Volume depletion without renal insufficiency may cause a disproportionate increase in the BUN, with little or no change in the creatinine concentration. This increase in the BUN may be absent or blunted in a child with
Correct Answer: C
Rationale: Poor protein intake reduces urea production, blunting BUN elevation, as BUN reflects protein metabolism.
Question 4 of 5
A specific sign of severe dehydration is
Correct Answer: C
Rationale: Reduced and mottled cutaneous perfusion is a specific sign of severe dehydration, indicating poor circulation.
Question 5 of 5
SJS is defined as epidermal detachment of less than 10 % of the body surface area, whereas SJS/TEN overlap has 10 % to 30 % and TEN has greater than 30 % body surface area involvement. Patients with Kawasaki disease have conjunctival injection and hyperemia of the mucous membranes but necrosis of the lesions does not occur; blistering, erosions, and severe crusting are not observed. The mucosal changes of staphylococcal scalded skin syndrome are minor, and frank erosions are not present. The blistering of the skin is more superficial and favors intertriginous regions.
Correct Answer: C
Rationale: Stevens-Johnson syndrome (SJS) is defined by <10% epidermal detachment, SJS/TEN overlap by 10-30%, and toxic epidermal necrolysis (TEN) by >30%, distinguishing it from other conditions like Kawasaki disease or staphylococcal scalded skin syndrome.
