1. In which type of cancer are the urinary excretion of the breakdown products of catecholamines, especially vanillylmandelic acid (VMA) and homovanillic acid (HVA), detected?

Correct answer: A

Rationale: The correct answer is A: Neuroblastoma. Neuroblastoma, a cancer that arises from nerve tissue, is associated with increased levels of catecholamine metabolites, including VMA and HVA, in the urine. Nephroblastoma (Wilms tumor) is a type of kidney cancer and is not typically associated with elevated levels of catecholamine breakdown products. Leukemia is a cancer of the blood and bone marrow and does not lead to increased VMA and HVA excretion in urine. Osteosarcoma is a bone cancer and is not linked to elevated levels of catecholamine metabolites in the urine.

2. A 3-year-old child was adopted immediately after birth. The parents have just asked the nurse how they should tell the child that she is adopted. Which guideline concerning adoption should the nurse use in planning a response?

Correct answer: D

Rationale: It is important to tell children about their adoption early, in an age-appropriate manner, as part of building trust and openness in the family relationship.

3. Which reflex, present at birth, is elicited by stroking the sole of the infant's foot, resulting in the fanning of the toes?

Correct answer: A

Rationale: The Babinski reflex is the correct answer. This reflex is characterized by the fanning out of the toes when the sole of the foot is stroked. It is a normal reflex in infants and is typically present at birth, disappearing by around 12 months of age. The Moro reflex, which involves the infant's response to a sudden loss of support or a loud noise, is not related to the fanning of toes. Sucking and rooting reflexes are related to feeding behaviors and are not elicited by stroking the sole of the foot.

4. During examination of a toddler's extremities, the nurse notes that the child is bowlegged. The nurse should recognize that this finding is which?

Correct answer: D

Rationale: Bowleggedness is normal in toddlers due to the development of lower back and leg muscles. It usually resolves as the child grows.

5. Which reflex is expected to disappear by 4 months of age?

Correct answer: B

Rationale: The Moro reflex, also known as the startle reflex, typically disappears by 4 months as the infant's nervous system matures. This reflex is important for assessing the development of the nervous system in newborns. The Rooting reflex (Choice A) is related to turning the head in response to cheek stimulation; the Babinski reflex (Choice C) involves the fanning of toes in response to foot stimulation; and the Palmar grasp (Choice D) is the curling of the fingers around an object placed in the infant's hand. These reflexes have different timelines for disappearance and are not typically expected to be gone by 4 months of age.
