Paramedics have brought a patient to the emergency department with a suspected heroin overdose. The nurse should recognize that the patient's most acute threat to health at this time is:

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. Ensure that there is a complete and functional suction system at the bedside. This is an essential precaution for clients with dysphagia because they are at high risk of aspiration. Having suction equipment ready allows for quick intervention if the client begins to choke or aspirate.

B. Position the head of the client's bed at a height of 30° to 45°. This positioning is too low for feeding. To reduce the risk of aspiration, the head of the bed should be elevated to at least 45° to 90° during feeding. Therefore, this option is less safe.

C. Provide two larger meals each day rather than three smaller meals in order to prevent fatigue. Smaller, more frequent meals are generally recommended to prevent fatigue and reduce the risk of aspiration, as larger meals can be overwhelming and increase the risk of choking.

D. Encourage the client to hold her breath while she is attempting to swallow. This is not a standard or safe practice for managing dysphagia. Safe swallowing techniques typically include ensuring the client is alert, properly positioned, and eating slowly with small bites.
