Rationale: The priority action for a child with suspected bacterial meningitis is to implement seizure precautions. Meningitis can lead to increased intracranial pressure, which may trigger seizures. By implementing seizure precautions, such as padding the side rails of the bed and ensuring a clear environment, the nurse aims to prevent injury during a potential seizure episode, prioritizing the child's safety.

Correct Answer: A

Rationale: Morphine, as a strong opioid agonist, has the highest likelihood of causing serious respiratory depression due to its potent effects on the central nervous system. While Pentazocine and Hydrocodone can also cause respiratory depression, they are less likely to do so compared to morphine. Nalmefene, an opioid antagonist, is used to reverse respiratory depression caused by opioids rather than causing it.

Correct Answer: D

Rationale: In hyperkalemia, cardiac arrhythmias are the most critical and life-threatening manifestation that requires immediate intervention. Hyperkalemia can lead to dangerous heart rhythm disturbances, potentially resulting in cardiac arrest. Prompt treatment is essential to stabilize the heart rhythm and prevent life-threatening complications.

Correct Answer: B

Rationale: In the case of Marge, who exhibits selective eating habits and struggles with weight gain, providing high-calorie snacks and meals at the table throughout the day can be an effective intervention. This strategy can help increase her food intake in a structured environment, promoting healthier eating habits and potentially addressing her below-average weight status. By offering calorie-dense foods at designated meal times, Marge may be more likely to consume the necessary nutrients to support her growth and development, ultimately improving her overall health.

Correct Answer: C

Rationale: A quiet alert state in infants indicates positive neurological development. It showcases the infant's ability to regulate sleep-wake cycles and maintain an optimal state for learning and interaction. Therefore, observing an infant who sleeps soundly, awakens on his own, and stays in a quiet alert state is a reassuring sign of neurological gains and healthy development.
