A nurse is contributing to the plan of care for a client who had prolonged exposure to cold weather and has a core body temperature of 32.5" C (90.5). Which of the following data is the priority for the nurse to monitor?

Choice A Reason: Pain sensation is incorrect. While assessing pain is important, it's generally secondary to addressing the life-threatening cardiac issues in hypothermia. Pain assessment can be done once the client's core temperature is stabilized. Choice B Reason: Urinary output is incorrect. Monitoring urinary output is essential for assessing kidney function and fluid balance, but it is not as immediately critical as assessing and addressing cardiac concerns. In a client with hypothermia, the priority for the nurse to monitor is: Choice C Reason: Heart rhythm is correct. Hypothermia can affect the electrical conductivity of the heart, potentially leading to life-threatening arrhythmias. Monitoring the client's heart rhythm is essential to detect any abnormalities and intervene promptly if necessary. While all the listed parameters are important, the cardiac status takes precedence due to the immediate threat it poses to the client's life. Choice D Reason: - Muscle strength is incorrect. Monitoring muscle strength is important to assess the client's overall neurological status, but it's not the top priority when there is a risk of life-threatening arrhythmias due to hypothermia.
