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 are neonates predisposed to problems with thermoregulation?

• A. Renal function is not fully developed
• B. Flexed posture favors heat loss
• C. A large body surface area favors heat loss to the environment
• D. A thick layer of subcutaneous fat provides excellent insulation

Correct answer: C

Rationale: Newborns have a large surface area relative to their body weight, making them more susceptible to heat loss and requiring careful thermoregulation. Choice A is incorrect because renal function is not directly related to thermoregulation. Choice B is incorrect because a flexed posture actually helps reduce heat loss by minimizing the surface area exposed to the environment. Choice D is incorrect because neonates have limited subcutaneous fat, which contributes to their susceptibility to heat loss.

3. What is the first step in treating a child with suspected anaphylaxis?

• A. Administer oxygen
• B. Start an IV line
• C. Give epinephrine
• D. Monitor vital signs

Correct answer: C

Rationale: The correct answer is C: Give epinephrine. Administering epinephrine is the first and most critical step in treating anaphylaxis. Epinephrine rapidly reverses the symptoms of anaphylaxis, including airway swelling, hypotension, and shock. Delaying administration can lead to severe complications or death, making it essential in emergency treatment. Choice A, administering oxygen, might be necessary but should not delay the administration of epinephrine. Starting an IV line (Choice B) is important for further treatment but not the initial step. Monitoring vital signs (Choice D) is essential but comes after administering epinephrine to stabilize the child.

4. The nurse is having difficulty communicating with a hospitalized 6-year-old child. Which technique should be most helpful?

• A. Recommend that the child keep a diary.
• B. Provide supplies for the child to draw a picture
• C. Suggest that the parent read fairy tales to the child
• D. Ask the parent if the child is always uncommunicative

Correct answer: B

Rationale: Drawing allows the child to express feelings and thoughts non-verbally, which can be particularly effective for children who have difficulty articulating their emotions.

5. A 5-year-old is hospitalized with a fractured femur. Which pain assessment tool is appropriate for this child?

• A. CRIES Scale
• B. Faces Pain Rating Scale
• C. SUN Scale
• D. NIPS Scale

Correct answer: B

Rationale: The Faces Pain Rating Scale is appropriate for assessing pain in children who can express their feelings visually. For a 5-year-old child who can communicate effectively, using a tool like the Faces Pain Rating Scale, which uses facial expressions to indicate pain levels, is more suitable than the CRIES Scale (used for neonates), the SUN Scale (used for infants), or the NIPS Scale (used for preterm and term newborns).
