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 sign is indicative of developmental dysplasia of the hip in infants?

• A. Ortolani sign
• B. Romberg sign
• C. Trendelenburg sign
• D. Gower's sign

Correct answer: A

Rationale: The Ortolani sign is a specific maneuver used during physical examination to detect hip instability or dislocation in infants. A positive Ortolani sign, where the hip is felt to slip back into the socket, is indicative of developmental dysplasia of the hip, a condition that can lead to long-term disability if not treated early. Romberg sign is used to assess sensory ataxia, Trendelenburg sign indicates weakness of the hip abductor muscles, and Gower's sign is seen in children with proximal muscle weakness climbing up their own body from a supine position due to conditions like muscular dystrophy.

3. A two-month-old infant who has gastroesophageal reflux is thriving without other complications. Which instruction should the nurse include in the teaching plan?

• A. Place the infant in the Trendelenburg position after feeding
• B. Thicken formula with rice cereal
• C. Give continuous nasogastric feedings
• D. Give larger, less frequent feeds

Correct answer: B

Rationale: The correct instruction for a two-month-old infant with gastroesophageal reflux who is thriving without complications is to thicken the formula with rice cereal. This can help reduce reflux by increasing the weight of the formula, making it less likely to be regurgitated. Placing the infant in the Trendelenburg position after feeding (Choice A) is not recommended as it can increase the risk of aspiration. Continuous nasogastric feedings (Choice C) are not typically indicated for uncomplicated reflux in infants. Giving larger, less frequent feeds (Choice D) can worsen reflux symptoms by overloading the stomach.

4. What is the earliest age at which a satisfactory radial pulse can be taken in children?

• A. 1 year
• B. 2 years
• C. 3 years
• D. 6 years

Correct answer: C

Rationale: A satisfactory radial pulse can typically be taken starting at around 3 years of age, as younger children often have pulses that are too fast and irregular for accurate measurement.

5. The nurse needs to take the blood pressure of a small child. Of the cuffs available, one is too large and one is too small. The best nursing action is which?

• A. Use the small cuff
• B. Use the large cuff
• C. Use either cuff using the palpation method
• D. Wait to take the blood pressure until a proper cuff can be located

Correct answer: D

Rationale: It is essential to use the correct cuff size for accurate blood pressure readings; if the proper size is not available, it's best to wait until it can be obtained.
