Nursing Elites

1. 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 sweat chloride test is the gold standard diagnostic test for cystic fibrosis as it measures the concentration of chloride in sweat. In cystic fibrosis, there is an abnormal transport of chloride across epithelial membranes, leading to elevated sweat chloride levels. A chest X-ray may show characteristic changes in the lungs associated with cystic fibrosis, but it is not a definitive diagnostic test. Pulmonary function tests assess lung function but do not specifically diagnose cystic fibrosis. Sputum culture may identify respiratory infections but does not confirm the diagnosis of cystic fibrosis.

2. A mother confides to the nurse that she is thinking of divorce. Which suggestion by the nurse would help minimize the effects on the child?

• A. Tell the child together using appropriate terms.
• B. Reassure the child that no one loves him more than his parents.
• C. Engage in special activities with the child to compensate for the divorce.
• D. Keep your feelings to yourself and maintain a positive facade with the child.

Correct answer: A

Rationale: In situations of divorce, it is crucial for both parents to inform the child together using age-appropriate language. This approach helps maintain consistency and clarity for the child, reducing confusion and anxiety. Choice B is incorrect because reassurance should not be solely focused on love but on explaining the situation appropriately. Choice C may inadvertently send the message that the divorce is the child's fault or requires compensation. Choice D is incorrect as children benefit from understanding and processing emotions in a healthy manner, rather than having them kept hidden.

3. An infant with hypertrophic pyloric stenosis (HPS) is admitted to the pediatric unit. What does the nurse expect 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 due to the hypertrophied pylorus muscle. Choices A, B, and D are incorrect. A distended colon is not typically associated with HPS. Marked tenderness around the umbilicus is not a specific finding of HPS. Rhythmic peristaltic waves in the lower abdomen are not expected in HPS, as the condition primarily affects the pylorus region of the stomach.

4. The healthcare provider is assessing an infant and notes that the infant's urine has a mousy or musty odor. What would the healthcare provider suspect?

• A. Maple syrup urine disease
• B. Tyrosinemia
• C. Phenylketonuria
• D. Trimethylaminuria

Correct answer: C

Rationale: Phenylketonuria (PKU) is suggested by a mousy or musty odor of the urine, caused by the inability to metabolize phenylalanine. Maple syrup urine disease (Choice A) is characterized by a sweet-smelling urine. Tyrosinemia (Choice B) presents with cabbage-like odor in the urine. Trimethylaminuria (Choice D) results in a fishy odor in the urine, breath, and sweat.

5. An instructor is developing a plan for a class of nursing students on various skin disorders. When describing urticaria, what would the 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, not type IV. When triggered, histamine release leads to vasodilation, causing characteristic wheals. Wheals are typically followed by erythema. The rash in urticaria is pruritic and does blanch with pressure, unlike the nonpruritic rash described in choice D. Therefore, the most appropriate description of urticaria includes histamine release and vasodilation, as stated in choice B.
