A nurse is caring for a child with newly diagnosed acute lymphoblastic leukemia. What clinical findings does the nurse anticipate when assessing the child? Select all that apply.

A. Rigid abdomen: A rigid abdomen is not a common finding in HPS. However, it is more typical in conditions such as intestinal obstruction.

B. Distended neck veins: Distended neck veins are not a typical manifestation of HPS. They may be associated with other cardiovascular or respiratory issues.

C. Red currant jelly stools: Red currant jelly-like stools are not typically seen in HPS. This description is often used to describe the appearance of stools in intussusception, which is a different gastrointestinal condition.

D. Projectile vomiting.

Hypertrophic pyloric stenosis is a condition in infants where the muscle at the outlet of the stomach (pylorus) becomes thickened and obstructs the passage of food from the stomach into the small intestine. Projectile vomiting is a characteristic symptom of HPS. The vomit is forceful and seems to shoot out of the infant's mouth, typically occurring after feeding.

Option A is incorrect because Tanner staging is not solely based on developmental achievement according to age. It assesses physical development irrespective of age.

Option B is incorrect because it is not based on the color of pigmentation on the scrotum but rather on multiple physical characteristics.

Option C. Based on the development of pubic hair in girls.

The Tanner staging system, also known as sexual maturity rating or sexual maturity scale, is a system used to assess the sexual development of children and adolescents based on physical characteristics, primarily focusing on secondary sexual characteristics. It is used to assess the stage of puberty in both boys and girls. In the case of girls, it includes the development of pubic hair, breast development, and other changes like the growth of the areola.

Option D is incorrect because it doesn't solely focus on staged voice changes in males. The Tanner staging system includes a range of characteristics, including voice changes, genital development, and pubic hair growth, to assess sexual maturity in both males and females.
