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. Why does the nurse have a 2-year-old boy sit in a “tailor” position while palpating for the presence of the testes?

• A. It prevents the cremasteric reflex
• B. Undescended testes can be palpated
• C. The child has an inguinal hernia
• D. The child does not yet have a need for privacy

Correct answer: A

Rationale: The tailor position stretches the muscle responsible for the cremasteric reflex, preventing it from contracting and pulling the testes into the pelvic cavity. This position helps accurately palpate the testes. Choice B is incorrect because the position does not facilitate the palpation of undescended testes specifically. Choice C is incorrect as it does not relate to the rationale behind the tailor position. Choice D is incorrect as the reason for using the tailor position is not related to the child's need for privacy.

3. For minimal change nephrotic syndrome (MCNS), prednisone is effective when what occurs?

• A. Appetite increases and blood pressure is normal
• B. Urinary tract infection is gone and edema subsides
• C. Generalized edema subsides and blood pressure is normal
• D. Diuresis occurs as urinary protein excretion diminishes

Correct answer: D

Rationale: The effectiveness of prednisone in treating MCNS is indicated by diuresis and a decrease in urinary protein excretion. Subsidence of generalized edema is also a positive sign, but the key indicator is the reduction in proteinuria, which is achieved through diuresis.

4. What laboratory finding should the nurse expect in a child with an excess of water?

• A. Decreased hematocrit
• B. High serum osmolality
• C. High urine specific gravity
• D. Increased blood urea nitrogen (BUN)

Correct answer: A

Rationale: Water excess typically leads to hemodilution, resulting in a decreased hematocrit. High serum osmolality and specific gravity would indicate dehydration, while elevated BUN could suggest renal impairment or dehydration, not fluid overload.

5. An anxious 12-year-old child receives an injection from the nurse and sighs with relief when it is done. After a moment of reflection, the girl asks the nurse, 'Is it hard to give someone an injection?' This child’s question is evidence that the child has developed which cognitive skill?

• A. Conservation
• B. Accommodation
• C. Decentering
• D. Class inclusion

Correct answer: C

Rationale: The correct answer is C: Decentering. Decentering is the ability to consider multiple aspects of a situation, which the child's question demonstrates. In this scenario, the child's question shows that she is thinking beyond her own experience and considering the difficulty or complexity of giving an injection from the nurse's perspective. Choices A, B, and D are incorrect. Conservation refers to understanding that certain properties of an object remain the same despite changes in its appearance. Accommodation is the process of adjusting existing knowledge or creating new mental categories to incorporate new information. Class inclusion involves understanding the relationship between a whole set and its subsets, which is not demonstrated in the child's question.
