ATI Nursing Care of Children

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. Iron supplements can cause stools to turn black, which is a normal and harmless side effect. Iron is best absorbed on an empty stomach, although it can be given with food if gastrointestinal upset occurs. Vitamin C, not D, enhances iron absorption. Choice B is incorrect because Vitamin C enhances iron absorption, not Vitamin D. Choice C is incorrect as there is no need to mix liquid iron with saliva before swallowing. Choice D is incorrect because iron is best absorbed on an empty stomach.

Correct Answer: D

Rationale: Accidents, such as motor vehicle accidents, drowning, and falls, are the primary cause of death in children over 1 year of age. While congenital anomalies can be a significant cause of mortality in infants, they are less common in older children. Homicide and suicide are serious issues but are not as prevalent as accidents in causing death among children over 1 year of age.

Correct Answer: D

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

Correct Answer: B

Rationale: The correct answer is B: Lack of surfactant. Respiratory distress syndrome (RDS) in preterm infants is primarily due to a lack of surfactant, which is crucial for keeping the lungs inflated. Without adequate surfactant, the alveoli collapse, leading to breathing difficulties. Choice A, Excessive surfactant, is incorrect as RDS is caused by an insufficient amount of surfactant. Choice C, Immature immune system, and Choice D, Lack of body fat, are not directly related to the development of respiratory distress syndrome in preterm infants.
