Nursing Elites

1. The school nurse is caring for a boy with hemophilia who fell on his arm during recess. What supportive measures should the nurse use until factor replacement therapy can be instituted?

• A. Apply warm, moist compresses
• B. Apply pressure for at least 1 minute
• C. Elevate the area above the level of the heart
• D. Begin passive range-of-motion unless the pain is severe

Correct answer: C

Rationale: The correct supportive measure for the school nurse to use for a boy with hemophilia who fell on his arm during recess is to elevate the area above the level of the heart. Elevating the affected area helps reduce bleeding and swelling in a child with hemophilia until factor replacement therapy can be provided. Applying warm, moist compresses (Choice A) may worsen bleeding by dilating blood vessels. Applying pressure for at least 1 minute (Choice B) is not recommended for hemophilia as it can lead to increased bleeding. Beginning passive range-of-motion (Choice D) should be avoided as it can exacerbate bleeding and further injury in a child with hemophilia.

2. 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.

3. When teaching a class about trisomy 21, the instructor would identify the cause of this disorder as:

• A. nondisjunction.
• B. X-linked recessive inheritance.
• C. genomic imprinting.
• D. autosomal dominant inheritance.

Correct answer: A

Rationale: Trisomy 21, also known as Down syndrome, is caused by nondisjunction, which is an error in cell division that leads to the presence of an extra chromosome 21. This additional chromosome alters the normal genetic makeup, resulting in the characteristics associated with Down syndrome. Therefore, the correct answer is nondisjunction (Choice A). Choices B, C, and D are incorrect because Trisomy 21 is not caused by X-linked recessive inheritance, genomic imprinting, or autosomal dominant inheritance. Understanding the specific genetic mechanism involved in Trisomy 21 is crucial for grasping the basis of this chromosomal disorder.

4. A parent and 4-year-old child who recently emigrated from Colombia arrive at the pediatric clinic. The child has a temperature of 102°F, is irritable, and has a runny nose. Inspection reveals a rash and several small, red, irregularly shaped spots with blue-white centers in the mouth. What illness does the nurse suspect the child has?

• A. Measles
• B. Chickenpox
• C. Fifth disease
• D. Scarlet fever

Correct answer: A

Rationale: The nurse should suspect measles in this child. The presence of a high fever, irritability, runny nose, rash, and Koplik spots (small, red spots with blue-white centers in the mouth) are classic signs of measles. Measles is a highly contagious viral illness that can lead to serious complications if not managed promptly. Chickenpox (choice B) presents with a different rash pattern and does not typically involve Koplik spots. Fifth disease (choice C) and scarlet fever (choice D) also have distinct clinical presentations and are not characterized by the specific symptoms described in this case.

5. A 5-year-old child is admitted to the hospital with a diagnosis of bacterial meningitis. What is the priority nursing intervention?

• A. Administering antibiotics
• B. Isolating the child
• C. Monitoring vital signs
• D. Administering fluids

Correct answer: B

Rationale: The priority nursing intervention for a child admitted with bacterial meningitis is isolating the child. Isolation is crucial to prevent the spread of the highly contagious infection to other patients and healthcare workers. Administering antibiotics (Choice A) is important but isolating the child takes precedence to contain the spread of the infection. Monitoring vital signs (Choice C) and administering fluids (Choice D) are essential aspects of care but do not address the immediate need to prevent transmission of the infection.
