A nurse is assisting with the care of a client who is at 30 weeks of gestation and has tuberculosis. Which of the following actions should the nurse take?

• Decreased respiratory effort, bilateral crackles: Reduced respiratory effort following opioid administration suggests opioid-induced respiratory depression. Crackles may indicate early airway compromise due to poor ventilation or fluid accumulation, requiring immediate intervention to support breathing.
• Somnolent: Somnolence beyond expected postoperative drowsiness, especially in combination with other signs of opioid overdose, indicates central nervous system depression. The client is difficult to arouse, raising concern for airway and breathing compromise.
• Pinpoint pupils: Pinpoint pupils are a hallmark sign of opioid toxicity. In the setting of recent morphine administration and accompanying respiratory depression, this finding confirms that opioid overdose is likely occurring and must be treated promptly.
• Respiratory rate 10/min: A respiratory rate under 12 breaths per minute following opioid administration is a major red flag for opioid-induced respiratory depression. Immediate action is needed to prevent further decline in respiratory status, including potential use of naloxone.
• Blood pressure 98/58 mm Hg: The client’s blood pressure has dropped significantly compared to the earlier reading, suggesting opioid-related hypotension. While not yet critically low, the trend combined with other overdose signs indicates instability needing close monitoring and intervention.
• Heart rate 58/min: Although the client is bradycardic, this alone is not the most urgent issue compared to respiratory depression and neurological decline. It should still be monitored closely, but it is less immediately life-threatening than the airway and breathing concerns.
• Temperature 37.4° C (99.4° F): This temperature is within normal range and does not require follow-up. There are no indications of infection or thermoregulatory issues based on the current temperature.

A. Hypertension: Clients experiencing diabetic ketoacidosis (DKA) are more likely to present with hypotension rather than hypertension due to dehydration caused by osmotic diuresis. Volume depletion significantly lowers blood pressure rather than raising it in the setting of DKA.

B. Fruity breath odor: A fruity or acetone-like breath odor is a hallmark sign of DKA. It results from the accumulation of ketones, particularly acetone, in the blood, which the body attempts to eliminate through the lungs, giving the breath its characteristic sweet or fruity smell.

C. Protruding eyeballs: Protruding eyeballs, or exophthalmos, are associated with hyperthyroidism, particularly Graves' disease, not with diabetic ketoacidosis. DKA affects metabolic and acid-base balance but does not cause changes to eye appearance or positioning.

D. Decreased urinary output: In the early stages of DKA, clients usually experience increased urinary output (polyuria) due to osmotic diuresis from hyperglycemia. Decreased output may occur only in the later stages when severe dehydration and kidney compromise develop, but it is not an early expected finding.
