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. An infant, age 6 months, has six teeth. The nurse should recognize that this is what?

• A. Normal tooth eruption
• B. Delayed tooth eruption
• C. Unusual and dangerous
• D. Earlier than expected tooth eruption

Correct answer: D

Rationale: Having six teeth at 6 months is earlier than the typical tooth eruption schedule, but it is not unusual or dangerous. It is within the range of normal variations in infant development.

3. A child with pyloric stenosis is having excessive vomiting. The nurse should assess for what potential complication?

• A. Hyperkalemia
• B. Hyperchloremia
• C. Metabolic acidosis
• D. Metabolic alkalosis

Correct answer: D

Rationale: Excessive vomiting in pyloric stenosis leads to the loss of stomach acid (hydrochloric acid), resulting in metabolic alkalosis, not hyperkalemia, hyperchloremia, or metabolic acidosis. Metabolic alkalosis is characterized by a higher pH level in the blood due to the loss of acid and a relative increase in bicarbonate. Hyperkalemia is an elevated level of potassium in the blood and is not directly related to excessive vomiting in pyloric stenosis. Hyperchloremia is an excess of chloride in the blood, which is not typically associated with this condition. Metabolic acidosis is a condition characterized by a lower pH level in the blood, caused by an excess of acid or a loss of bicarbonate, which is not the typical complication seen in pyloric stenosis with excessive vomiting.

4. Which parameter correlates best with measurements of total muscle mass?

• A. Height
• B. Weight
• C. Skinfold thickness
• D. Upper arm circumference

Correct answer: D

Rationale: Upper arm circumference correlates best with total muscle mass because it includes both muscle and fat components, making it a reliable indicator of muscle mass.

5. Which type of play is most appropriate for a hospitalized toddler?

• A. Cooperative play
• B. Parallel play
• C. Competitive play
• D. Solitary play

Correct answer: B

Rationale: The most appropriate type of play for a hospitalized toddler is parallel play. This type of play allows toddlers to engage alongside each other but not directly with each other, which can be comforting and less overwhelming in a hospital setting. Cooperative play (choice A) involves working together towards a common goal, which may be challenging for a hospitalized toddler. Competitive play (choice C) involves a level of rivalry that may not be suitable during a hospital stay. Solitary play (choice D) involves playing alone, which may not provide the social interaction and distraction that parallel play can offer in a hospital environment.
