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. What clinical manifestation should be the most suggestive of acute appendicitis?

• A. Rebound tenderness
• B. Bright red or dark red rectal bleeding
• C. Abdominal pain that is relieved by eating
• D. Colicky, cramping abdominal pain around the umbilicus

Correct answer: D

Rationale: The correct answer is D: Colicky, cramping abdominal pain around the umbilicus. This type of pain is a common early sign of acute appendicitis. Rebound tenderness, choice A, is a later sign seen in the physical examination of a patient with appendicitis. Rectal bleeding, as described in choice B, is not typically associated with appendicitis. Abdominal pain that is relieved by eating, as mentioned in choice C, is more indicative of peptic ulcer disease rather than appendicitis.

3. What interventions would the nurse implement to maintain the skin integrity of a preterm infant born at 30 weeks?

• A. Avoid using alkaline-based soap.
• B. Bathe the infant with sterile water.
• C. Cleanse skin with a gentle alkaline-based soap and water.
• D. Thoroughly rinse skin with plain water after bathing in a mild hexachlorophene solution.

Correct answer: B

Rationale: To maintain the skin integrity of a preterm infant born at 30 weeks, the nurse should bathe the infant with sterile water no more than two or three times per week. The eyes, oral and diaper areas, and pressure points should be cleansed daily. It is essential to avoid using alkaline-based soaps as they might destroy the 'acid mantle' of the skin. Additionally, cleansing with mild solutions and rinsing thoroughly with plain water is recommended to prevent skin irritation and maintain skin integrity. Therefore, options A, C, and D are incorrect as they do not align with the best practices for preterm infant skin care.

4. What amount of fluid loss occurs with moderate dehydration?

• A. <50 ml/kg
• B. 50 to 90 ml/kg
• C. <5% total body weight
• D. >15% total body weight

Correct answer: B

Rationale: Moderate dehydration is typically defined as a loss of 50 to 90 mL/kg of body weight. This amount reflects significant fluid loss that requires medical attention but is not yet severe.

5. The nurse is assessing a child's capillary refill time. This can be accomplished by doing what?

• A. Inspect the chest
• B. Auscultate the heart
• C. Palpate the apical pulse
• D. Palpate the nail bed with pressure to produce a slight blanching

Correct answer: D

Rationale: Capillary refill time is assessed by applying pressure to the nail bed and observing how quickly the color returns, indicating peripheral circulation status.
