When caring for four clients, which does the nurse identify as at the highest risk for frostbite?
19-year old who takes antihistamines
28-year old who is a vegetarian
41-year old who is being treated for hypothyroidism
57-year old who drinks 4-5 beers per day
The Correct Answer is C
A. Antihistamines can cause mild drowsiness or decreased sweating, but they do not significantly impair thermoregulation. This client may have a slightly higher susceptibility to cold if drowsiness limits activity, but it is not a major risk factor for frostbite compared to other physiologic conditions.
B. A vegetarian diet may influence overall nutrition, potentially reducing certain micronutrients like vitamin B12 or iron, which can affect general health. However, in healthy adults, a well-planned vegetarian diet does not significantly increase susceptibility to cold injuries or frostbite.
C. Hypothyroidism reduces basal metabolic rate, which decreases heat production, and it impairs peripheral vasoconstriction, the body’s natural defense against cold exposure. Even if the patient is on thyroid hormone replacement, thermoregulatory responses may still be slower or insufficient in extreme cold, putting them at high risk for frostbite. Early recognition and protective measures are essential.
D. Chronic alcohol consumption can cause peripheral vasodilation and a false sense of warmth, increasing the risk of hypothermia and frostbite. However, compared with hypothyroidism, alcohol’s effect is more behavioral (impaired judgment and awareness of cold) rather than a primary physiologic impairment of heat production, so this client is at moderate risk, not the highest.

Correct Answer is C
Explanation
A. While looking for tattooing or 'branding' markscan provide evidence of abuse, it is not the first action. This is part of a physical assessment, which should follow establishing safety and rapport with the client.
B. Completing a full psychosocial assessmentis important, but first the nurse must ensure the client is in a safe environmentto disclose sensitive information. A comprehensive assessment can be conducted after addressing immediate safety concerns.
C. The priority is to assess for safety and potential abuse. Asking a direct, nonjudgmental question like, "Does anyone you know make you feel unsafe?"allows the client an opportunity to disclose abuse in a safe and private setting. Safety is always the first priority when domestic or intimate partner violence is suspected.
D. Following agency policy for reportingis important, but it is not the first action. Nurses must first assess the situation and confirm immediate safety needsbefore initiating reports. Immediate reporting without client disclosure or context may not address urgent safety concerns.
Correct Answer is D
Explanation
A. This response minimizes the staff member’s emotional experienceby suggesting that the distress is temporary and will resolve on its own. While it is true that time may lessen the intensity of memories, telling someone this does not provide validation, emotional support, or guidance. Minimizing the reaction can increase feelings of isolation or guilt and may delay proper coping or treatmentfor acute stress.
B. Although taking time off might reduce physical fatigue and allow some mental recovery, it does not address the underlying psychological trauma. A staff member experiencing intrusive memories may require structured emotional support, counseling, or intervention, not just rest. Simply suggesting leave could imply that the responsibility is on the individual to “feel better” alone.
C. Peer support is valuable, but it is not sufficient for staff experiencing intrusive, distressing memories, especially after a disaster. This statement is well-intentioned but minimizes the seriousness of the psychological responseand may delay access to professional mental health support.
D. This response validates the staff member’s feelingsby acknowledging that seeing the faces of deceased victims is distressing and that professional support is appropriate. It provides immediate support, safety, and access to mental health resources, such as counseling, debriefing, or employee assistance programs. Offering to accompany the staff member also demonstrates empathy, trust, and advocacy, which are critical in disaster response scenarios.
