The nurse assesses that the patient is having a sympathetic response when noting what manifestations?
A) Decrease in sweating, decrease in respirations, and pupil constriction
B) Decrease in heart rate and perfusion, and an increase in inflammatory reactions
C) Increase in blood pressure, bronchodilation, and decreased bowel sounds
D) Increased motility and secretions in the GI tract, and constriction of bronchi and pupils
C
Feedback:
When stimulated, the sympathetic nervous system prepares the body to flee or to turn and fight (Figure 29.3). Cardiovascular activity increases, as do blood pressure, heart rate, and blood flow to the skeletal muscles. Respiratory efficiency also increases; bronchi dilate to allow more air to enter with each breath, and the respiratory rate increases. Pupils dilate to permit more light to enter the eye, to improve vision in darkened areas (which helps a person to see to fight or flee). Sweating increases to dissipate heat generated by the increased metabolic activity.
