ATI Nursing Care of Children

Correct Answer: A

Rationale: The correct dosage to administer 20 mg is 0.4 mL, calculated by dividing the dose (20 mg) by the concentration (100 mg in 2 mL). This calculation ensures the accurate administration of the prescribed medication. Choices B, C, and D are incorrect as they do not reflect the correct calculation based on the provided concentration of the medication.

Correct Answer: B

Rationale: The correct answer is B: "Age-specific tasks that most children can do at a certain time." Developmental milestones are specific tasks or abilities that most children can achieve at a certain age range. Choices A, C, and D are incorrect because developmental milestones are not just about increase in body size, the direction of growth, or the age group of children. They are more focused on the expected tasks and skills children can accomplish at particular ages.

Correct Answer: A

Rationale: The correct answer is A: Transition from fetal to neonatal breathing. The most critical physiological change required of newborns at birth is the initiation of breathing. This transition is crucial for the newborn to start exchanging oxygen and carbon dioxide outside the womb, marking the beginning of their independent respiratory function. Choices B, C, and D are important aspects of newborn care but are not as immediately critical as the establishment of breathing for oxygenation and removal of carbon dioxide, which is essential for the newborn's survival and adaptation to extrauterine life.

Correct Answer: A

Rationale: The correct answer is A, 'Having imaginary playmates.' Preschool-age children often engage in imaginative play, which includes creating imaginary friends or playmates. This type of play helps them develop creativity, social skills, and emotional expression. Choice B, 'Selective collection of objects,' may be more common in older children and is not a typical play activity for preschoolers. Choice C, 'Complex board games,' are usually beyond the developmental level of preschoolers as they require more advanced cognitive skills. Choice D, 'Associative play,' is a term used to describe a type of play where children play alongside each other but not necessarily together, which is different from the imaginative play involving imaginary playmates that preschoolers often engage in.

Correct Answer: D

Rationale: Setting clear goals, praising good behavior, and modeling appropriate behavior are effective strategies for minimizing misbehavior in children.
