Sexual abuse should be considered in children who have behavioral problems, although no behavior is pathognomonic. Which of the following behavior should raise the suspicion of sexual abuse?

Correct Answer: D

Rationale: Hypersexuality in children is highly unusual and strongly indicative of possible sexual abuse, as it reflects exposure to inappropriate sexual content or experiences.

Correct Answer: D

Rationale: Vitamin D is essential for the absorption of calcium in the body. Without sufficient vitamin D, the absorption of calcium from the diet is impaired, leading to potential issues with calcium deficiency. Vitamin A, B, and C do not have a direct role in the absorption of calcium. Vitamin D helps regulate the amount of calcium and phosphate in the body, which are necessary for bone health, muscle function, and other important processes. Therefore, a lack of Vitamin D can contribute to weakened bones and potential health problems related to calcium deficiency.

Correct Answer: A

Rationale: Play serves as a method to assist disturbed children by providing them with a therapeutic outlet to express themselves and work through their emotions in a safe and constructive manner.

Correct Answer: D

Rationale: A neonate born to a mother with blood type AB and a father with blood type O is at risk for ABO blood incompatibility, particularly if the neonate is blood type A or B. The major sign of ABO blood incompatibility in the neonate is the development of jaundice within the first 24 hours of life. This occurs due to the mismatch in blood types between the mother and the neonate, leading to the destruction of the neonate's red blood cells. This destruction releases bilirubin, causing jaundice. It is important to note that unlike Rh incompatibility, ABO incompatibility usually does not lead to severe complications requiring treatment. A positive Coombs test result is not typically seen in ABO blood incompatibility.

Correct Answer: B

Rationale: Autism screening is recommended between 18 and 24 months.
