Nursing Elites

1. When describing urticaria, what would an instructor include?

• A. It is a type IV hypersensitivity reaction.
• B. Histamine release leads to vasodilation.
• C. Wheals appear first followed by erythema.
• D. The nonpruritic rash blanches with pressure.

Correct answer: B

Rationale: The correct answer is B. Urticaria is a type I hypersensitivity reaction where histamine release leads to vasodilation and the formation of characteristic wheals. Choice A is incorrect as urticaria is associated with type I hypersensitivity, not type IV. Choice C is incorrect because in urticaria, erythema typically appears before the development of wheals. Choice D is incorrect as urticaria is typically pruritic and does not blanch with pressure.

2. An order is written for an isotonic enema for a 2-year-old child. What is the maximum amount of fluid the nurse should administer without a specific order from the health care provider?

• A. 100 to 150 mL
• B. 155 to 250 mL
• C. 255 to 360 mL
• D. 365 to 500 mL

Correct answer: B

Rationale: For a 2-year-old child, the maximum recommended amount of fluid for an isotonic enema is between 155 to 250 mL to prevent overdistension and potential harm. Choice A (100 to 150 mL) is too low and may not be effective in achieving the desired outcome. Choices C (255 to 360 mL) and D (365 to 500 mL) exceed the safe range for a 2-year-old child and can lead to overdistension, electrolyte imbalance, or other complications. Therefore, the correct answer is B.

3. A 3-year-old child with a history of frequent respiratory infections is being evaluated for cystic fibrosis. What diagnostic test should the nurse anticipate will be ordered?

• A. Chest X-ray
• B. Sweat chloride test
• C. Pulmonary function test
• D. Sputum culture

Correct answer: B

Rationale: The correct answer is the sweat chloride test. This test is crucial in diagnosing cystic fibrosis as it measures the amount of chloride in sweat, which is typically elevated in individuals with cystic fibrosis. A chest X-ray (Choice A) may show characteristic findings like hyperinflation or bronchiectasis, but it is not a definitive diagnostic test for cystic fibrosis. Pulmonary function tests (Choice C) may help assess lung function but are not specific for cystic fibrosis. Sputum culture (Choice D) may be used to identify specific pathogens causing respiratory infections but is not a primary diagnostic test for cystic fibrosis.

4. The nurse is assessing a family to determine if they have access to adequate health care. Which statement accurately describes how certain families are affected by common barriers to health care?

• A. After a decade of escalation, the percentage of children living in low-income families has been on the decline since 2000.
• B. White, non-Hispanic children overall are more likely than African American and Hispanic children to be in very good or excellent health.
• C. The proportion of children between the ages of 6 and 18 who are overweight is decreasing, but a large increase is occurring in African American females.
• D. The overall health care plan of working families may improve access to specialty care but limit access to preventive services.

Correct answer: B

Rationale: Choice B is the correct answer because it accurately states that White, non-Hispanic children are more likely to be in very good or excellent health compared to African American and Hispanic children. This reflects a disparity in health outcomes among different racial groups. Choices A, C, and D are incorrect. Choice A is unrelated to the impact of common barriers to health care on families. Choice C talks about overweight children but does not address access to health care. Choice D discusses the impact of the overall health care plan on working families but does not specifically address the disparity in health status among different racial groups.

5. An infant with hypertrophic pyloric stenosis (HPS) is admitted to the pediatric unit. What does the nurse expect to find when palpating the infant’s abdomen?

• A. A distended colon
• B. Marked tenderness around the umbilicus
• C. An olive-sized mass in the right upper quadrant
• D. Rhythmic peristaltic waves in the lower abdomen

Correct answer: C

Rationale: When palpating the abdomen of an infant with hypertrophic pyloric stenosis (HPS), the nurse would expect to feel an olive-sized mass in the right upper quadrant. This finding is characteristic of HPS, where the hypertrophied pyloric muscle forms a palpable mass in the abdomen. Choices A, B, and D are incorrect. A distended colon is not a typical finding in HPS, marked tenderness around the umbilicus is not specific to this condition, and rhythmic peristaltic waves in the lower abdomen are not associated with HPS.
