A nurse is preparing to apply lidocaine and prilocaine cream to a child prior to the insertion of an IV catheter. Which of the following actions should the nurse plan to take?

- A: Tighten the screws on the halo device one-quarter turn every 48 hr.
- Rationale: This action is incorrect because the screws on a halo device should not be adjusted by the nurse. The screws are typically set and secured by a healthcare provider, and any adjustments can compromise the integrity of the device and the stability of the cervical spine.

- B: Assess the pin sites for infection once every other day.
- Rationale: While it is important to monitor the pin sites for signs of infection, doing so once every other day may not be sufficient. Pin sites should be assessed at least once per shift to ensure early detection and management of any potential infection.

- C: Encourage flexion and extension of the neck.
- Rationale: This action is contraindicated for a client with a halo vest. The purpose of the halo vest is to immobilize the cervical spine to promote healing. Encouraging neck movement could cause further injury or delay healing.

- D: Reposition the client using a turning sheet.
- Rationale: This is the correct action. Using a turning sheet helps to reposition the client safely and effectively without exerting unnecessary pressure on the cervical spine. It also aids in preventing pressure ulcers and promotes comfort for the client.

A. "Your child's feet should be 3 to 6 inches off the ground when seated on the bicycle." This instruction is not related to safety. Proper seat height is important for comfort and efficiency but does not directly impact safety.

B. This is the correct instruction. Maintaining a distance of at least 3 feet from the curb while riding in the street allows space for maneuvering and helps prevent collisions with obstacles or parked cars.

C. "Your child should walk the bicycle through intersections." This is a good safety practice. Walking the bicycle through intersections reduces the risk of accidents with other vehicles.

D. "Your child should ride the bicycle against the flow of traffic." This is incorrect.
Children should ride their bicycles in the same direction as traffic. Riding against traffic increases the risk of accidents.
