Question
A patient with PTSD startles easily and reacts
irritably to small annoyances. The nurse
interprets this as which of the following?
A. Hyperarousal
B. Intrusion
C. Avoidance
D. Numbing
Copyright © 2015 Wolters Kluwer • All Rights Reserved
Answer
A. Hyperarousal
• Hyperarousal is manifested by being
hypervigilant for signs of danger, becoming
easily startled, reacting irritably to small
annoyances and sleeping poorly. Intrusion
refers to the individual continually
experiencing the event through flashbacks
and nightmares. Avoidance and numbing
reflect complete powerlessness by the
individual.
