Chapter 29: The Child with Musculoskeletal or Articular Dysfunction - Nurselytic

Correct Answer: B

Rationale: Immobilization reduces metabolic rate, slowing systems and food intake. It causes hypercalcemia, negative nitrogen balance from muscle atrophy, and decreased stress hormone production due to reduced coping capacity.

Correct Answer: B

Rationale: Fractures in children heal faster in younger individuals due to robust periosteum and bone pliability. Growth plates are prone to fractures, children?s bones are more porous and pliable, and their periosteum is thicker with greater osteogenic potential than adults?.

Correct Answer: C

Rationale: A Salter type III fracture through the epiphyseal plate requires specific management, often surgical, to prevent growth complications like angular deformities. Hand dominance is irrelevant, healing is rapid at the growth plate, and complete immobilization isn?t always needed.

Correct Answer: C

Rationale: Gaining the child?s trust by calmly assessing pain location and finger movement is the priority to evaluate neurovascular status without increasing distress. Radiography requires initial assessment, morphine is premature, and restraining the child escalates anxiety.

Correct Answer: B

Rationale: Elevating the casted arm during rest and in a sling when upright promotes venous return and reduces swelling. Strenuous activity is limited initially, shoulder movement is encouraged, and finger swelling requires immediate reporting to prevent neurovascular damage.
