The nurse is caring for a patient who came to the emergency department with confusion and muscle cramps after working outside on a hot day. What is the priority action of the nurse?

A. Errors by the nurse assistant in measuring temperature. While improper technique can lead to inaccurate readings, consistent temperature fluctuations in a head injury patient are more likely due to hypothalamic dysfunction.
B. Increased vasodilatation of the superficial vessels contributing to excess heat losses. Vasodilation can play a role in heat loss, but it does not fully explain difficulty maintaining body temperature, which is primarily regulated by the hypothalamus.
C. The client's head injury causing interference with the function of the hypothalamus. The hypothalamus regulates body temperature, and a severe head injury can disrupt this function, leading to temperature instability (neurogenic fever or hypothermia) despite the absence of infection.
D. Choosing the wrong time of day to obtain vital signs. While body temperature naturally fluctuates throughout the day, major instability in temperature regulation is not due to the timing of measurement but rather an issue with the hypothalamus.

A. Bradypnea refers to an abnormally slow respiratory rate, typically below 12 breaths per minute in an adult. A rate of 32 breaths/min is too fast to be considered bradypnea.
B. Apnea is the absence of breathing for a prolonged period. Since the patient has a respiratory rate of 32 breaths/min, apnea does not apply.
C. Tachypnea is defined as a rapid respiratory rate exceeding 20 breaths per minute in an adult. A rate of 32 breaths/min indicates tachypnea, which may be caused by conditions such as fever, anxiety, or respiratory distress.
D. Eupnea refers to normal breathing, with a respiratory rate between 12–20 breaths per minute. A rate of 32 breaths/min is too high to be considered eupnea.
