Correct Answer: D

Rationale: In a 3-year-old child presenting with sudden respiratory distress without fever or recent illness, the most likely cause is a foreign body airway obstruction. Foreign body airway obstruction can lead to a sudden onset of respiratory distress as it blocks the air passage. Croup typically presents with a barking cough and stridor, often preceded by a viral illness. Epiglottitis is characterized by high fever, drooling, and a muffled voice. Lower respiratory infections usually present with symptoms such as cough, fever, and chest congestion. Therefore, in this case, the absence of recent illness or fever makes foreign body airway obstruction the most likely cause of the respiratory distress.

Rationale: The correct answer is D: Pubic bone malformation. Exstrophy of the bladder is commonly associated with pubic bone malformation as the condition involves a defect in the pelvic region. Imperforate anus, absence of one kidney, and congenital heart disease are not typically associated with exstrophy of the bladder, making them incorrect choices. Therefore, the nurse should primarily assess the infant for pubic bone malformation in this case.

Correct Answer: B

Rationale: Lifting the baby from under the armpits can cause fractures in infants with osteogenesis imperfecta. The correct approach is to support the baby's body and head carefully, avoiding pressure on vulnerable areas prone to fractures. Choices A, C, and D demonstrate proper awareness of caring for an infant with osteogenesis imperfecta by emphasizing caution to prevent fractures.

Correct Answer: A

Rationale: When observing a toddler in a playroom with other children, a caregiver would expect to witness parallel play. Parallel play is common among toddlers, where they play alongside but not directly with other children. This type of play is characterized by children engaging in similar activities near each other without interactive or cooperative play. Solitary play (Choice B) involves a child playing alone, while cooperative play (Choice C) involves children playing together towards a common goal. Competitive play (Choice D) involves activities where children compete against each other.
