1.Explain how reduced blood flow in an area can interfere with healing and increase the risk of infection.

2.L.D. is a 13-year-old healthy teenager who is very anxious about getting her wisdom teeth removed by the dentist. She is afraid that the dentist will use a needle to “freeze” her mouth. In the past, she has felt light-headed and dizzy when receiving routine immunizations in the doctor’s office. Her mother thinks that L.D.’s anxious behavior is silly and tries to reassure L.D. on the drive to the dental office that everything will be fine. The dental office is quite busy and the receptionist states that the dentist has had an emergency patient and there will be a delay before L.D. will be seen. L.D. waits 30 minutes for her appointment.

(1)What stressors are present for L.D.?

(2) How will the delay affect L.D.’s stress response? What could reduce L.D.’s stress during the wait?

(3)When L.D. is finally called by the receptionist, she gets up and immediately feels like she is going to faint. Which change in the nervous system is responsible for her hypotension? Is this part of the usual response to stressors?

(4)She is sweating and her pupils are dilated. What specific changes have occurred to cause these manifestations? 5. L.D.’s mother tells her to “calm down” and “be brave.” How would this likely affect the stress L.D. is experiencing?
