A nurse is collecting data from a client who uses a continuous positive airway pressure (CPAP) machine at night for sleep apnea. The nurse should identify which of the following findings as an indication of proper CPAP use?

A. "Provide informational updates to members of the media" is incorrect. This task typically falls under the responsibility of the hospital’s public relations or communications team. Nurses do not usually handle media updates in the context of mass casualty events.

B. "Assist in discharging stable clients to home" is correct. During a mass casualty event, it is important to make room for incoming patients. Discharging stable patients helps free up beds and resources for those who need immediate care.

C. "Delegate tasks to emergency health care specialists" is incorrect. While nurses may delegate some tasks, the nurse’s primary responsibility in this scenario would be managing care within the medical-surgical unit, not directing emergency health care specialists.

D. "Determine the acuity and number of casualties arriving at the facility" is incorrect. This task is generally managed by triage teams or emergency management staff who assess incoming patients at the point of injury or arrival at the facility.

A. Initiates speech rarely: This is a negative symptom of schizophrenia, where the individual may exhibit a lack of motivation or interest in social interaction, leading to reduced speech or verbal communication. Negative symptoms refer to the absence or decrease of normal functioning or behaviors, such as lack of speech, emotional expression, or motivation.

B. Has a preoccupation with religious thoughts: This is more of a positive symptom, potentially indicating delusions or hallucinations. Positive symptoms involve the presence of abnormal thoughts or behaviors.

C. Mimics the nurse's movements: This behavior, called echopraxia, is a positive symptom of schizophrenia, which involves involuntary imitation of another person's movements.

D. Smells odors that don't exist: This is a hallucination, which is a positive symptom of schizophrenia. Hallucinations are sensory perceptions without external stimuli, such as hearing voices or smelling things that aren’t there.
