A nurse is reinforcing teaching to the parents of an infant about the correct use of infant car seats. Which of the following statements by the parents indicates an understanding of the teaching?

• 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. "Check the water temperature with your finger": Checking water temperature with a finger is unreliable because fingers may tolerate higher temperatures without discomfort. It is recommended to use the inside of the wrist or a thermometer to ensure the water is warm but not hot, typically around 100°F (37.8°C), to prevent burns.

B. "Hold your baby under running water when washing his hair": Holding a newborn under running water is unsafe because it can cause sudden chilling, difficulty breathing, or even slipping. Instead, caregivers should use a damp, warm washcloth or gently pour water over the baby's head while securely supporting it.

C. "Cleanse the eyes from the inner canthus outward": Cleaning from the inner to the outer canthus is correct technique because it prevents introducing contaminants into the tear duct. This motion also minimizes the spread of bacteria, reducing the risk of eye infections in the delicate eyes of a newborn.

D. "Set the water heater to 125.6 degrees Fahrenheit": A water heater set to 125.6°F presents a high risk of scald burns in infants. Safety guidelines recommend setting the water heater to no higher than 120°F (48.9°C) to reduce the risk of accidental burns during bathing or household water use.
