Correct Answer is D

Explanation

- 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. Perform developmental testing for delays. B. Initiate a low-iron diet for lead absorption. C. Obtain a stool specimen for lead levels. D. Inspect the skin for discoloration.

Correct Answer is A

Explanation

A. Toddlers with a history of lead poisoning are at risk for developmental delays.
Developmental testing can help identify any delays that may require intervention or support.

B. Lead absorption is not related to iron intake. However, a diet rich in iron can help reduce the absorption of lead.

C. Blood testing, not stool testing, is the primary method for assessing lead levels. Blood lead levels provide the most accurate information about lead exposure.

D. While lead poisoning can cause changes in skin color in severe cases, it is not the primary assessment for lead exposure. Blood lead levels and developmental testing are more indicative of lead poisoning.
