A. Family members report that pain has subsided. Pain is a subjective experience, and the patient's own report is the most reliable indicator of pain relief, not the observations of family members.
B. Vital signs have returned to baseline. While pain can affect vital signs, such as increasing heart rate or blood pressure, their return to normal does not necessarily indicate adequate pain relief. Some patients may still experience significant pain despite stable vital signs.
C. Body language is incongruent with reports of pain relief. Nonverbal cues can be helpful in assessing pain, but they should not override the patient’s self-reported pain level, which is the most accurate measure.
D. You compare assessed pain with baseline pain. The best way to evaluate the effectiveness of PCA analgesia is to assess the patient’s pain level before and after medication administration, comparing it to baseline pain. This provides an objective measure of pain relief.

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.
