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 is the most effective way to prevent the spread of hand, foot, and mouth disease in a daycare setting?

• A. Handwashing
• B. Isolating sick children
• C. Disinfecting toys
• D. Encouraging vaccination

Correct answer: A

Rationale: Handwashing is indeed the most effective way to prevent the spread of hand, foot, and mouth disease in children. Proper hand hygiene helps in removing and killing germs that can cause infections. While isolating sick children and disinfecting toys are important measures to prevent the spread of diseases, they are not as effective as handwashing. Encouraging vaccination, in this case, is not relevant since there is no specific vaccine available for hand, foot, and mouth disease.

3. Physiologically, the child compensates for fluid volume losses by which mechanism?

• A. Inhibition of aldosterone secretion
• B. Hemoconcentration to reduce cardiac workload
• C. Fluid shift from interstitial space to intravascular space
• D. Vasodilation of peripheral arterioles to increase perfusion

Correct answer: C

Rationale: In response to dehydration, the body compensates by shifting fluids from the interstitial spaces to the intravascular space to maintain blood pressure and perfusion to vital organs. Hemoconcentration and vasoconstriction are other compensatory mechanisms but are less immediate.

4. An infant weighed 8 lb at birth and was 18 inches in length. What weight and length should the infant be at 5 months of age?

• A. 12 lb, 20 inches
• B. 14 lb, 21.5 inches
• C. 16 lb, 23 inches
• D. 18 lb, 24.5 inches

Correct answer: C

Rationale: By 5 months, an infant's weight should typically double from birth, and length should increase by approximately 50%.

5. When should the dressing change for a post-op pediatric patient that is expected to be very painful and frightening be performed?

• A. In the patient’s room
• B. In the treatment room
• C. After discharge when the patient is at home
• D. In the playroom

Correct answer: B

Rationale: The correct answer is B: 'In the treatment room.' Performing painful procedures in the treatment room helps the child associate their own room with safety and comfort, not pain. Choice A is incorrect because performing the dressing change in the patient’s room may create a negative association with their safe space. Choice C is incorrect as it is important to ensure proper wound care and pain management before discharge. Choice D is incorrect as the playroom may not be equipped for a sterile dressing change.
