A client is admitted to an inpatient psychiatric unit for treatment of obsessive-compulsive symptoms. Obsessive- compulsive disorder (OCD) is associated with:

A. Hypokalemia or hyponatremia: While electrolyte imbalances are important, they are not the most immediate threat in the context of a heroin overdose.

B. Acute gastrointestinal bleed: An acute gastrointestinal bleed is not a primary concern with heroin overdose. It is not the most acute threat in this scenario.

C. Increased intracranial pressure: Increased intracranial pressure is not directly related to heroin overdose. The most pressing issue is related to the effects of the overdose.

D. Respiratory depression: Heroin overdose commonly leads to respiratory depression, which is the most immediate and life-threatening condition. Addressing respiratory depression is crucial for patient survival.

A. Comprehend spoken words: This is part of global aphasia, but it does not fully encompass the deficits associated with this condition. Global aphasia involves more extensive language impairment.

B. Form words that are understandable: This is part of global aphasia, but it alone does not fully capture the severity of the language deficit, as it also includes comprehension issues.

C. Form words that are understandable or comprehend spoken words: Global aphasia is the most severe form of aphasia, characterized by profound impairment in both the ability to produce understandable speech and comprehend spoken language. This choice accurately reflects the full scope of the language deficits in global aphasia.

D. Speak at all: Clients with global aphasia may still attempt to speak, but their speech is typically not understandable and is often meaningless. Therefore, saying they cannot "speak at all" is not entirely accurate.
