Answer to Question 1

Ans: B
Off-label use of prazosin, an alpha1 inhibitor, has recently been shown to be effective in treating nightmares and improving sleep in clients with PTSD. Selective serotonin reuptake inhibitors (SSRIs), benzodiazepines, and b-blockers also have been shown to be effective in reducing the symptoms of PTSD.

Answer to Question 2

Ans: A
Behavioral sensitization may be one mechanism underlying the hyperarousal seen in posttraumatic stress disorder (PTSD). This phenomenon, sometimes referred to as kindling, occurs after exposure to severe, uncontrollable stressors. A sensitized person reacts with a magnified stress response to later, milder stressors. Research shows that a single or repeated exposure to a severe stressor potentiates the capacity of a subsequent stressor to increase synaptic levels of norepinephrine and dopamine in the forebrain. This finding would account for the fact that some individuals with PTSD experience intense fear, anxiety, and panic in response to minor stimuli. One example of behavioral sensitization is that PTSD after combat exposure is more likely to develop in veterans who are survivors of childhood abuse than in those who have not experienced prior trauma.

Bisphosphonates were first developed in the nineteenth century. They were first investigated for use in disorders of bone metabolism in the 1960s.

As many as 28% of hospitalized patients requiring mechanical ventilators to help them breathe (for more than 48 hours) will develop ventilator-associated pneumonia. Current therapy involves intravenous antibiotics, but new antibiotics that can be inhaled (and more directly treat the infection) are being developed.
