- A. Having an ethical framework in place prior to an emergency
- B. Allowing staff to provide care anonymously during an emergency
- C. Assuring staff that they are not legally accountable for care provided during an emergency

- A. Cover their eyes.
- B. Put on a personal protective equipment mask.

- A. Practice outside of her normal area of clinical expertise.
- B. Perform interventions that are not based on assessment data.
- C. Prioritize psychosocial needs over physiologic needs.

- A. Erythema
- B. Ecchymosis

Correct Answer: D
Rationale: High radiation doses (>5,000 rads) cause skin necrosis within days to months. Lower doses cause erythema or desquamation, and ecchymosis is unrelated.
