Nursing Elites

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?

• A. Neuroblastoma
• B. Nephroblastoma
• C. Leukemia
• D. Osteosarcoma

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. The nurse is discussing development and play activities with the parent of a 2-month-old boy. Which statement by the parent would indicate a correct understanding of the teaching?

• A. I can give my baby a ball of yarn to pull apart or different textured fabrics to feel
• B. I can use a music box and soft mobiles as appropriate play activities for my baby
• C. I should introduce a cup and spoon or push-pull toys for my baby at this age
• D. I do not have to worry about appropriate play activities at this age

Correct answer: B

Rationale: At 2 months, infants are most stimulated by visual and auditory activities, such as a music box or soft mobiles. These activities help in sensory development and are appropriate for this age.

3. Why are neonates predisposed to problems with thermoregulation?

• A. Renal function is not fully developed
• B. Flexed posture favors heat loss
• C. A large body surface area favors heat loss to the environment
• D. A thick layer of subcutaneous fat provides excellent insulation

Correct answer: C

Rationale: Newborns have a large surface area relative to their body weight, making them more susceptible to heat loss and requiring careful thermoregulation. Choice A is incorrect because renal function is not directly related to thermoregulation. Choice B is incorrect because a flexed posture actually helps reduce heat loss by minimizing the surface area exposed to the environment. Choice D is incorrect because neonates have limited subcutaneous fat, which contributes to their susceptibility to heat loss.

4. A child has been diagnosed with a Wilms tumor. What should preoperative nursing care include?

• A. Careful bathing and handling
• B. Monitoring of behavioral status
• C. Maintenance of strict isolation
• D. Administration of packed red blood cells

Correct answer: A

Rationale: The correct answer is A: Careful bathing and handling. Preoperative care for a child with a Wilms tumor should focus on preventing any trauma to the abdomen, which could lead to tumor rupture. Monitoring behavioral status and maintaining strict isolation are not as critical in this situation. Behavioral status is important but not a priority in preoperative care for a Wilms tumor. Strict isolation is not necessary unless there are specific infectious concerns, which is not typically the case for a Wilms tumor. Administration of packed red blood cells is not a standard preoperative intervention for Wilms tumor.

5. What diet is most appropriate for the child with chronic renal failure (CRF)?

• A. Low in protein
• B. Low in vitamin D
• C. Low in phosphorus
• D. Supplemented with vitamins A, E, and K

Correct answer: C

Rationale: A low-phosphorus diet is important in managing chronic renal failure to prevent hyperphosphatemia and its associated complications, such as bone disease. Protein intake should be controlled but not necessarily low, and vitamin D supplementation is often required, not reduced.
