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. The nurse is caring for a child with the following order: Methylprednisolone (Solu-Medrol) 20 mg IV, every 6 hours. The nurse has Methylprednisolone 100 mg in 2 mL available. How many mL should the nurse administer with each dose?

• A. 0.4 mL
• B. 0.2 mL
• C. 0.5 mL
• D. 0.6 mL

Correct answer: A

Rationale: The correct dosage to administer 20 mg is 0.4 mL, calculated by dividing the dose (20 mg) by the concentration (100 mg in 2 mL). This calculation ensures the accurate administration of the prescribed medication. Choices B, C, and D are incorrect as they do not reflect the correct calculation based on the provided concentration of the medication.

3. The nurse is evaluating research studies according to the GRADE criteria and has determined the quality of evidence on the subject is moderate. Which type of evidence does this determination indicate?

• A. Strong evidence from unbiased observational studies
• B. Evidence from randomized clinical trials showed inconsistent results
• C. Consistent evidence from well-performed randomized clinical trials
• D. Evidence for at least one critical outcome from randomized clinical trials had serious flaws

Correct answer: B

Rationale: Moderate evidence typically indicates that results from randomized clinical trials were inconsistent, highlighting the need for further research to confirm findings.

4. A teen with asthma asks the nurse why it is hard to breathe during an asthma attack. The nurse explains that exposure to a “trigger” results in which of these manifestations?

• A. Bronchodilation, muscle relaxation, and decreased mucus production
• B. Air trapping and hypo-inflation of the alveoli
• C. Air trapping and decreased blood flow to the upper airway
• D. Bronchoconstriction, airway inflammation, and excess mucus production

Correct answer: D

Rationale: The correct answer is D. Asthma triggers cause bronchoconstriction, airway inflammation, and increased mucus production, leading to difficulty breathing. This combination of manifestations results in narrowing of the airways, making it hard for the individual to breathe effectively. Choices A, B, and C are incorrect because during an asthma attack, bronchodilation, muscle relaxation, and decreased mucus production do not occur. Instead, the airways constrict, become inflamed, and produce excess mucus, contributing to the breathing difficulties experienced by individuals with asthma.

5. The nurse suspects that a child has ingested some type of poison. What clinical manifestation would be most suggestive that the poison was a corrosive product?

• A. Tinnitus
• B. Disorientation
• C. Stupor, lethargy, and coma
• D. Edema of the lips, tongue, and pharynx

Correct answer: D

Rationale: Edema of the lips, tongue, and pharynx is a characteristic sign of corrosive poisoning, indicating damage to mucous membranes from ingestion of a caustic substance. Other symptoms may vary depending on the poison but are not as specific to corrosive ingestion.
