Correct Answer: A

Rationale: The correct answer is A: Respiratory syncytial virus (RSV). RSV is the most common cause of bronchiolitis, especially in infants. Bronchiolitis is characterized by inflammation of the small airways in the lungs. Choice B, Haemophilus influenzae, is a bacterium that can cause respiratory infections but is not the primary cause of bronchiolitis. Choice C, Parainfluenza, is a common viral infection that can cause croup and other respiratory illnesses but is not the main cause of bronchiolitis. Choice D, Rotavirus, is a virus that primarily affects the gastrointestinal system, causing diarrhea and vomiting, and is not associated with bronchiolitis.

Correct Answer: A

Rationale: Preschoolers may engage in magical thinking and believe inanimate objects are alive, so the nurse should explain the equipment in a way that reduces fear.

Correct Answer: B

Rationale: To maintain the skin integrity of a preterm infant born at 30 weeks, the nurse should bathe the infant with sterile water no more than two or three times per week. The eyes, oral and diaper areas, and pressure points should be cleansed daily. It is essential to avoid using alkaline-based soaps as they might destroy the 'acid mantle' of the skin. Additionally, cleansing with mild solutions and rinsing thoroughly with plain water is recommended to prevent skin irritation and maintain skin integrity. Therefore, options A, C, and D are incorrect as they do not align with the best practices for preterm infant skin care.

Correct Answer: C

Rationale: The correct answer is C: 'The condition is incompatible with life.' Anencephaly is the most serious neural tube defect where both hemispheres of the brain are absent. It is incompatible with life, as there are no medical or surgical treatment options available. While some infants with mature brain stem function can maintain vital functions for a short period, anencephaly is ultimately not survivable. Choice A is incorrect as there are no treatment options for anencephaly. Choice B is incorrect as immediate surgery is not necessary for this condition. Choice D is incorrect as an infant with anencephaly will not have permanent disabilities since the condition is not compatible with life.

Correct Answer: B

Rationale: Adolescents may withdraw from social interactions, worry about the impact of the divorce, and express strong emotions such as anger or sadness.
