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. A 3-year-old child, previously potty-trained, becomes a bed-wetter again during a hospital stay. Which explanation should the nurse provide to the parents?

• A. “Your child is no longer potty-trained and will need to be retrained when she goes home.”
• B. “The child may have developed a bladder infection in the hospital. I will notify the doctor.”
• C. “Preschool children may regress in their behaviors when they are ill in the hospital but should return to normal when they go back home.”
• D. “Don’t worry about it, she is fine.”

Correct answer: C

Rationale: During a hospital stay, preschool children may exhibit regression in behaviors such as bed-wetting due to stress. It is important for parents to understand that this behavior is a common response to the hospital environment and should resolve once the child is back home. Therefore, the correct explanation for the nurse to provide to the parents is choice C. Choice A is incorrect because it inaccurately states that the child is no longer potty-trained. Choice B is incorrect as it assumes a medical issue without evidence. Choice D is incorrect as it dismisses the parents' concerns without addressing the underlying cause of the behavior.

3. The nurse is caring for a child with acute renal failure. What laboratory findings should the nurse expect to find? (Select all that apply.)

• A. Hyponatremia
• B. Hyperkalemia
• C. All are applicable
• D. Elevated blood urea nitrogen level

Correct answer: C

Rationale: In acute renal failure, laboratory findings typically include hyperkalemia, hyponatremia, and elevated blood urea nitrogen (BUN) levels due to the kidneys' inability to excrete waste and balance electrolytes. Metabolic alkalosis is less common, with metabolic acidosis being more typical.

4. What is the most critical physiological change required of newborns at birth?

• A. Transition from fetal to neonatal breathing
• B. Body temperature maintenance
• C. Stabilization of fluid and electrolytes
• D. Closure of fetal shunts in the heart

Correct answer: A

Rationale: The correct answer is A: Transition from fetal to neonatal breathing. The most critical physiological change required of newborns at birth is the initiation of breathing. This transition is crucial for the newborn to start exchanging oxygen and carbon dioxide outside the womb, marking the beginning of their independent respiratory function. Choices B, C, and D are important aspects of newborn care but are not as immediately critical as the establishment of breathing for oxygenation and removal of carbon dioxide, which is essential for the newborn's survival and adaptation to extrauterine life.

5. According to Erikson’s developmental theory, toddlers need to be encouraged to become independent to successfully complete which developmental challenge?

• A. Trust vs. mistrust
• B. Industry vs. inferiority
• C. Autonomy vs. shame and doubt
• D. Initiative vs. guilt

Correct answer: C

Rationale: The correct answer is C: Autonomy vs. shame and doubt. Erikson's developmental stage for toddlers focuses on the conflict between developing a sense of independence (autonomy) and feelings of inadequacy (shame and doubt). Encouraging toddlers to explore their environment and make choices helps them build self-confidence and independence. Choices A, B, and D are incorrect because trust vs. mistrust relates to infancy, industry vs. inferiority is associated with school-age children, and initiative vs. guilt is linked to preschoolers.
