Correct Answer: B

Rationale: The correct answer is B: Suppressor T cells. Suppressor T cells regulate the immune response by inhibiting the activity of other immune cells to prevent overreaction and maintain immune balance. They play a crucial role in preventing autoimmune diseases and excessive inflammation. Plasma cells (A) produce antibodies, Helper T cells (C) assist in activating other immune cells, and B lymphocytes (D) are involved in antibody production. Suppressor T cells specifically have the function of shutting down immune responses, making them the immune system’s shutoff mechanism.

Correct Answer: A

Rationale: The correct answer is A: Avoiding using soap on the irradiated areas. This is because soap can irritate the skin, leading to skin breakdown in a client at risk for impaired skin integrity due to radiation therapy. Avoiding soap helps to prevent further damage to the skin. Choice B is incorrect as talcum powder can further irritate the skin and should be avoided. Choice C is not relevant to preventing skin integrity issues. Choice D is incorrect because thoracic skin markings should not be removed as they are essential for accurate radiation delivery.

Correct Answer: D

Rationale: The correct answer is D: Presence of laryngospasm. Laryngospasm is a serious complication of trauma to the upper airway that can lead to airway obstruction. Assessing for laryngospasm is crucial to ensure the client's airway remains patent. Pain when talking (A) is more related to vocal cord injury, increased nasal swelling (B) is a symptom of nasal trauma, and burning in the throat (C) may indicate pharyngeal injury, but laryngospasm (D) directly affects airway patency in upper airway trauma cases.

Correct Answer: C

Rationale: Rationale for Correct Answer (C): Asking the NAP to record the patient's vital signs before administering medications is the correct clinical decision. Vital signs are crucial indicators of a patient's health status and should be documented before any interventions. By having the NAP record the vital signs, the nurse ensures that the patient's condition is properly assessed and monitored. This action aligns with the standard of care and promotes patient safety. Summary of Incorrect Choices: A: Administering medications without knowing the patient's vital signs could be dangerous, especially if there are abnormalities that need attention. B: Reviewing vital signs upon return delays necessary assessment and intervention, potentially compromising patient safety. D: Omitting vital signs without assessment puts the patient at risk, as changes in vital signs can indicate underlying issues that need immediate attention.

Correct Answer: C

Rationale: The correct answer is C. The nurse should ask the NAP to record the patient's vital signs before administering medications. This is important for ensuring patient safety and monitoring any potential changes in the patient's condition. By having the NAP record the vital signs, the nurse can assess the patient's current status and make informed decisions regarding medication administration. Option A is incorrect because administering medications without knowing the patient's vital signs, especially if they are abnormal, can be risky. Option B is not the best choice as it delays addressing the missing vital signs. Option D is incorrect as omitting vital signs assessment is not in line with best practices for patient care.
