Correct Answer: B

Rationale: In the management of acute sickle cell pain crisis in children, morphine is the preferred medication due to its effectiveness in providing pain relief. Meperidine (Demerol) is less commonly used in this scenario because of its potential for neurotoxicity with repeated doses. Acetaminophen (Tylenol) and Ibuprofen (Motrin) are not typically sufficient for managing the severe pain associated with sickle cell crises and are not the first-line treatment options.

Correct Answer: A

Rationale: Small objects are a choking hazard for infants, so it is crucial to keep them out of reach to prevent injury.

Correct Answer: D

Rationale: Cutting hot dogs into small, irregular pieces reduces the risk of aspiration, which is a significant choking hazard for young children.

Correct Answer: B

Rationale: In this case, the infant's symptoms are consistent with narcotic withdrawal. Infants exposed to drugs in utero may display withdrawal symptoms starting around 12 to 24 hours post-birth. The presentation often includes hyperactive reflexes, tremors, sneezing, high-pitched shrill cry, poor feeding, and sucking avidly on hands. Signs such as loose stools, tachycardia, fever, projectile vomiting, sneezing, and generalized sweating are common. These symptoms are not indicative of a seizure disorder. Placental insufficiency typically leads to a small-for-gestational-age child, which is not mentioned in the scenario. Meconium aspiration syndrome primarily presents with respiratory distress, not the symptoms described in this case.

Correct Answer: D

Rationale: At 6 months, infants typically begin to combine syllables like "dada" or "mama," but they do not yet understand the meaning of these words.
