emergency department (ED) physician is concerned that the client may have intentionally
crashed her car and requests a stat PMHNP consult. In speaking with the PMHNP, the client
describes persistent feelings of sadness and hopelessness. She states that she often wonders if
her husband would be happier if she wasn't around anymore since she's never happy and
sometimes thinks about what it would be like to just take a handful of sleeping pills and go to
sleep forever. The client reports a previous suicide attempt when she was 16 but denies that
she is considering killing herself right now.
Based on the client's ASQ score, what is the most appropriate response?
No action is necessary as the client is not currently considering suicide.

Alert the client's primary care physician.
Provide a ST - Provide a brief suicide safety assessment.

full mental health evaluation in necessary. It is also important to notify the client's physician or
the clinician responsible for the client's care.
