For which involuntary physiologic response would the nurse monitor development in a client experiencing pain?

• A. Perspiring
• B. Palpitations
• C. Nausea
• D. Tremors

Answer: (A)

Pain often triggers the body's automatic, or autonomic, responses through the sympathetic nervous system. Sweating is a classic sign of this autonomic arousal and tends to accompany increasing pain or distress, making perspiring a reliable observable cue for a nurse to monitor as pain develops or worsens. This is particularly useful when a patient cannot clearly communicate pain, since sweating can be seen even when words aren’t available.

Palpitations describe a patient’s subjective sensation of a racing heart, which isn’t as directly observable by the nurse and depends on patient reporting. Nausea can occur for various reasons, not solely due to pain, and tremors can arise from anxiety or other factors, not specifically from pain. Therefore perspiring stands out as the best involuntary physiologic indicator of pain development to monitor.
