OCC OCC Pediatric & Special Population Casting 1 — Questions and Answers
Question 1: Why is extra padding used when casting pediatric patients compared to adults?
- Children have more prominent bony areas and less subcutaneous tissue (Correct answer)
- Children require thicker casts for activity restriction
- Pediatric skin is thicker and requires more compression
- Children move less, so padding prevents cast loosening
Correct answer: Children have more prominent bony areas and less subcutaneous tissue
Bony prominences in children have less protective fat and are at greater risk for pressure injury, requiring additional padding.
Question 2: The 'three-point mold' technique is especially important in pediatric casting because:
- Children have softer bones that may angulate if the cast is not properly molded (Correct answer)
- Children require casts to be removed more frequently
- Pediatric casts use faster-setting plaster
- Children cannot tolerate fiberglass materials
Correct answer: Children have softer bones that may angulate if the cast is not properly molded
Proper three-point molding maintains fracture alignment in children whose immature bone remodeling relies heavily on correct cast geometry.
Question 3: In toddlers and infants, which type of cast is commonly used to treat developmental dysplasia of the hip (DDH)?
- Spica cast (Correct answer)
- Short arm cast
- Long leg cast
- Slipper cast
Correct answer: Spica cast
A hip spica cast holds the hips in the abducted, flexed position required to seat the femoral head in the acetabulum during DDH treatment.
Question 4: Which color-coded system is used to guide padding at vulnerable areas in pediatric casts?
- There is no color system; anatomy landmarks guide extra padding placement (Correct answer)
- Red padding for high-risk areas, green for low-risk
- Blue marks for bony prominences, yellow for skin folds
- Standard hospital color bands matching allergy status
Correct answer: There is no color system; anatomy landmarks guide extra padding placement
Padding placement in pediatric casts is guided by anatomical landmarks rather than a color-coded system; extra padding is placed over identified bony prominences.
Question 5: When casting a child with an upper extremity fracture, the wrist is typically positioned in:
- Slight extension (10-15 degrees) for most forearm fractures (Correct answer)
- Full flexion to relax the flexor tendons
- Neutral (0 degrees) for all pediatric wrist injuries
- Full extension to maximize immobilization
Correct answer: Slight extension (10-15 degrees) for most forearm fractures
Slight wrist extension is the standard functional position for most pediatric forearm and wrist fractures unless otherwise specified by the clinician.
Question 6: A parent asks if their child can bathe with a fiberglass cast. The correct response is:
- The cast must be kept dry; use a waterproof cast cover for bathing (Correct answer)
- Fiberglass casts are fully waterproof and bathing is allowed
- Sponge bath only is needed and the cast can get minimally wet
- Bathing must be avoided entirely until cast removal
Correct answer: The cast must be kept dry; use a waterproof cast cover for bathing
Standard fiberglass casts are not fully waterproof because the inner padding absorbs water; a waterproof liner system is required for water exposure.
