A nurse is teaching a class about physical manifestations associated with the fight-or-flight response to stress. Which of the following manifestations should the nurse include?

The correct answer is C: Dilated pupils. During the fight-or-flight response, the sympathetic nervous system is activated, causing the pupils to dilate to allow more light in for improved vision to better assess the threat. This physiological response helps individuals to be more alert and responsive in stressful situations. Bronchial airway constriction (A) is associated with asthma, not the fight-or-flight response. Hypoglycemia (B) is a drop in blood sugar levels, not a typical manifestation of the fight-or-flight response. Decreased blood pressure (D) is not a characteristic of the fight-or-flight response, as blood pressure typically increases to supply more oxygen and nutrients to the muscles.
