Correct Answer: C

Rationale: A spiral fracture is a type of fracture often associated with twisting injuries and can raise suspicion of child abuse. This type of fracture is caused by a twisting force applied to a bone. Plastic deformity is not typically associated with fractures but refers to the ability of a material to change shape and retain that shape. A buckle fracture, also known as a torus fracture, is an incomplete break in a bone commonly seen in children. A greenstick fracture is an incomplete fracture where the bone is bent and partially broken, more commonly seen in children due to their bone flexibility.

Correct Answer: A

Rationale: Placing the infant on their back to sleep is the correct recommendation to reduce the risk of sudden infant death syndrome (SIDS). This sleep position has been shown to significantly decrease the incidence of SIDS. Using a pacifier during sleep (Choice B) can also help reduce the risk, but it is secondary to the back sleeping position. Having the infant sleep on their side (Choice C) is not recommended, as it increases the risk of SIDS. Keeping the infant's room cool (Choice D) may provide a comfortable sleeping environment but does not directly reduce the risk of SIDS.

Correct Answer: B

Rationale: Limiting screen time is a crucial recommendation to prevent childhood obesity. Excessive screen time is associated with sedentary behavior and increased consumption of unhealthy snacks, leading to weight gain. Encouraging high-calorie snacks (Choice A) contradicts the goal of preventing obesity. While fast food as a treat (Choice C) can be consumed occasionally, it should not be encouraged as a regular practice. Allowing the child to eat freely (Choice D) without restrictions can lead to overeating and unhealthy dietary habits, contributing to obesity risk.

Correct Answer: A

Rationale: Epicanthal folds are a distinctive physical feature commonly observed in individuals with Down syndrome. These are horizontal skin folds that cover the inner corners of the eyes. Webbed neck (choice B) is not typically associated with Down syndrome but can be seen in conditions like Turner syndrome. Enlarged head (choice C) is not a characteristic feature of Down syndrome; however, individuals with hydrocephalus may present with this finding. Polydactyly (choice D) is the presence of extra fingers or toes, which is not a typical feature of Down syndrome.
