Final Answer:
Posttraumatic stress disorder (PTSD) signs and symptoms encompass hyperalertness, sleep disturbances, memory loss related to the trauma, somatic distress, hostility, and violent behavior. Thus, the correct answers are 1. hyperalertness and sleep disturbances, 2. memory loss of traumatic event and somatic distress and 3. feelings of hostility and violent behavior.
Step-by-step explanation:
Individuals experiencing PTSD, especially veterans exposed to traumatic events like combat, often exhibit hyperalertness, being constantly on edge, and experiencing difficulty in relaxing or sleeping due to recurring nightmares or insomnia. Memory loss concerning the traumatic event is common, along with somatic distress manifesting as physical symptoms related to the trauma, such as headaches or gastrointestinal issues.
Feelings of hostility and increased irritability are prevalent, leading to outbursts of anger or aggressive behavior. It's essential to note that while some individuals with PTSD might display these symptoms, others may not, as responses to trauma vary among individuals.
Moreover, sudden behavioral changes, such as avoidance of situations reminiscent of the trauma or emotional numbing, can also occur. However, anorexia or a significant loss of appetite is not typically considered a primary symptom of PTSD. Instead, changes in appetite might lean towards either overeating or loss of interest in food as part of altered behavior patterns associated with PTSD.
Understanding these signs and symptoms is crucial for healthcare professionals in providing appropriate care and support for individuals coping with PTSD, particularly for veterans who might have encountered traumatic experiences during their service.
Thus, the correct answers are 1. hyperalertness and sleep disturbances, 2. memory loss of traumatic event and somatic distress and 3. feelings of hostility and violent behavior.
