Nursing Elites

1. Which heart sound is produced by vibrations within the heart chambers or in the major arteries from the back-and-forth flow of blood?

• A. S1 and S2
• B. S3 and S4
• C. Murmur
• D. Physiologic splitting

Correct answer: C

Rationale: A murmur is produced by turbulent blood flow within the heart or major arteries, resulting in audible vibrations.

2. 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.

3. One of the most critical needs of the infant is control of body temperature. The nurse caring for a newborn warms all equipment that comes in direct contact with the newborn to help prevent which type of heat loss?

• A. Convection
• B. Evaporation
• C. Conduction
• D. Radiation

Correct answer: C

Rationale: The correct answer is Conduction (choice C). Conduction heat loss occurs when the newborn’s skin comes into direct contact with a cooler surface, so warming equipment helps prevent this. Choice A, Convection, is the transfer of heat through air or water currents, not direct contact. Choice B, Evaporation, is the loss of heat through moisture on the skin evaporating, not direct contact. Choice D, Radiation, is the transfer of heat in the form of waves or particles, not direct contact.

4. The school nurse is explaining to older school children that obesity increases the risk for which disorders? (Select all that apply.)

• A. Asthma
• B. Hypertension
• C. Dyslipidemia
• D. All of the above

Correct answer: D

Rationale: Obesity increases the risk for conditions like asthma, hypertension, dyslipidemia, and altered glucose metabolism, but not typically irritable bowel disease.

5. When a pre-school child says the sun shines to keep her warm, this is an example of:

• A. Animism
• B. Artificialism
• C. Egocentrism
• D. Centering

Correct answer: B

Rationale: The correct answer is B: Artificialism. Artificialism is the belief that natural phenomena are created by human beings for human purposes. In this scenario, the child attributes human-like intentions to the sun, assuming it shines specifically to keep her warm. Choice A, Animism, is the belief that natural objects and phenomena are alive and have feelings. Choice C, Egocentrism, refers to a child's difficulty in seeing things from another person's perspective. Choice D, Centering, involves focusing on only one aspect of a situation while ignoring other relevant aspects.
