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. Which physiological acid-base balance complication would be most important for the nurse to assess in a patient with diarrhea?

• A. High serum pH
• B. Normal serum pH
• C. Metabolic alkalosis
• D. Metabolic acidosis

Correct answer: D

Rationale: The correct answer is metabolic acidosis. Diarrhea can lead to the loss of bicarbonate, causing an imbalance in the acid-base status of the body, specifically resulting in metabolic acidosis. High serum pH (choice A) is incorrect as diarrhea-induced bicarbonate loss would lower pH, not increase it. Normal serum pH (choice B) is not the best answer as diarrhea can disrupt the acid-base balance. Metabolic alkalosis (choice C) is an alkaline state, which is less likely to be caused by diarrhea.

3. The nurse is performing an oral examination on a preschool child. Which strategies should the nurse use to encourage the child to open the mouth for the examination? (Select all that apply.)

• A. Lightly brush the palate with a cotton swab
• B. Perform the examination in front of a mirror
• C. Let the child examine someone else's mouth first
• D. All of the above

Correct answer: D

Rationale: Using a cotton swab, allowing the child to observe, and demonstrating on someone else are effective ways to encourage a preschooler to open their mouth for examination.

4. What is the most appropriate nursing action when intermittently gavage feeding a preterm infant?

• A. Allow formula to flow by gravity
• B. Avoid allowing the infant to suck on the tube
• C. Insert the tube through the nares instead of the mouth
• D. Apply gentle pressure to the syringe to deliver the formula

Correct answer: A

Rationale: The correct action when intermittently gavage feeding a preterm infant is to allow the formula to flow by gravity. This method helps prevent overfeeding and aspiration, which can occur if the formula is delivered too quickly under pressure. Choice B is incorrect as sucking on the tube can cause complications. Choice C is incorrect as the tube is typically inserted through the mouth. Choice D is incorrect as steady pressure can lead to rapid delivery of the formula, increasing the risk of complications.

5. The nurse is assessing a 3-year-old child. Which assessment finding would the nurse identify as abnormal?

• A. Pedals tricycle without assistance
• B. Unscrews a bolt on a toy
• C. Falls when bending over to touch toes
• D. Builds a tower of 10 cubes

Correct answer: C

Rationale: The correct answer is C. Falling when bending over to touch toes could indicate a developmental delay or a balance issue that may need further assessment. Choices A, B, and D are typical developmental milestones for a 3-year-old child. Pedaling a tricycle without assistance, unscrewing a bolt on a toy, and building a tower of 10 cubes are all age-appropriate activities for a child of this age.
