An anxious client enters the emergency department seeking treatment for a laceration of the finger. The client's vital signs are pulse 106 beats per minute, blood pressure (BP) 158/88 mm Hg, and respirations 28 breaths per minute. After cleansing the injury and reassuring the client, the nurse rechecks the vital signs and notes a pulse of 82 beats per minute, BP 130/80 mm Hg, and respirations 20 breaths per minute. Which factor likely accounts for the change in vital signs?

  • A. Cooling effects of the cleansing agent
  • B. Client's adaptation to the air conditioning
  • C. Early clinical indicators of cardiogenic shock
  • D. Decline in sympathetic nervous system discharge
Correct Answer: D

Rationale: Physical or emotional stress triggers sympathetic nervous system stimulation. Increased epinephrine and norepinephrine cause tachycardia, high blood pressure, and tachypnea. Stress reduction then returns these parameters to baseline as the sympathetic discharge falls.
