A nurse is caring for an adolescent following the application of a plaster cast for a fractured right tibia.
Which of the following actions should the nurse take?
Discourage the client from ambulating.
Keep the client's leg in a dependent position.
Use a hair dryer on a hot setting to dry the cast.
Perform a neurovascular check of the lower extremities.
The Correct Answer is D
Choice A rationale
Discouraging the client from ambulating is not necessary. In fact, early ambulation is often encouraged to promote circulation and prevent complications, depending on the fracture
type and treatment plan.
Choice B rationale
Keeping the client's leg in a dependent position is not recommended as it can increase swelling and pain. Elevating the leg is typically advised to reduce swelling.
Choice C rationale
Using a hair dryer on a hot setting to dry the cast is unsafe as it can cause burns and damage the cast. It's better to allow the cast to dry naturally and follow the healthcare provider's
instructions.
Choice D rationale
Performing a neurovascular check of the lower extremities is crucial to assess circulation, sensation, and movement. This helps in identifying any complications such as impaired
blood flow or nerve damage.

Correct Answer is B
Explanation
Choice A rationale
The lap belt fitting snugly over the child's abdomen increases the risk of abdominal injury during a crash.
Choice B rationale
The lap belt fitting low across the child's hips distributes force over stronger bony structures, reducing injury risk.
Choice C rationale
Placing a child in the front seat with a shoulder-only automatic belt does not provide proper restraint and increases injury risk.
Choice D rationale
The shoulder strap crossing just below the child's chin indicates improper fit, posing a risk to the neck in a crash.
Correct Answer is D
Explanation
Choice A rationale
A 6-month-old infant typically grasps objects voluntarily, which is a normal developmental milestone.
Choice B rationale
The posterior fontanel usually closes between 2 to 3 months of age, so it being closed at 6 months is normal.
Choice C rationale
It's expected for an infant's birth weight to double by about 5 to 6 months of age, indicating healthy growth.
Choice D rationale
Head lag in a 6-month-old indicates a delay in motor development and should be reported as it can signal neurological issues.
