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 6-month-old infant is admitted with a diagnosis of respiratory syncytial virus (RSV). What should the nurse include in the care plan?

• A. Providing small, frequent feedings
• B. Administering antibiotics
• C. Maintaining strict isolation
• D. Elevating the head of the bed

Correct answer: D

Rationale: Elevating the head of the bed is essential in the care of an infant with RSV as it helps improve breathing by reducing congestion and promoting drainage. This position also aids in maintaining patent airways and can enhance comfort for the infant. Providing small, frequent feedings (Choice A) is generally appropriate for infants but is not a specific intervention for RSV. Administering antibiotics (Choice B) is not indicated for RSV, as it is a viral infection and antibiotics are ineffective against viruses. Maintaining strict isolation (Choice C) is important to prevent the spread of infections, but it is not a direct care intervention for managing RSV symptoms.

3. An infant is admitted to the neonatal intensive care unit (NICU) with exstrophy of the bladder. What covering should the nurse use to protect the exposed area?

• A. Loose diaper
• B. Dry gauze dressing
• C. Moist sterile dressing
• D. Petroleum jelly gauze pad

Correct answer: C

Rationale: In cases of exstrophy of the bladder, a moist sterile dressing is the most appropriate choice to protect the exposed bladder tissue. Moist sterile dressings help maintain a clean environment, prevent infection, and promote healing. A loose diaper (Choice A) may not provide adequate protection and may lead to contamination. Dry gauze dressing (Choice B) could adhere to the wound and cause trauma upon removal. Petroleum jelly gauze pad (Choice D) is not ideal as it may not provide the necessary barrier against infection and could potentially cause irritation.

4. The nurse is caring for a 12-year-old boy with idiopathic thrombocytopenia. The nurse is providing discharge instructions about home care and safety recommendations to the boy and his parents. Which response indicates a need for further teaching?

• A. We should avoid aspirin and drugs like ibuprofen.
• B. He should avoid participating in football for safety.
• C. Swimming would be a great activity.
• D. Our son cannot take any antihistamines.

Correct answer: B

Rationale: The correct answer is B. Participation in contact sports like football should be avoided in children with idiopathic thrombocytopenia due to the increased risk of bleeding. Choices A, C, and D are incorrect because avoiding aspirin and drugs like ibuprofen, engaging in activities like swimming, and avoiding antihistamines are all appropriate recommendations for a child with idiopathic thrombocytopenia to prevent bleeding episodes and ensure safety.

5. A child with a cardiac malformation associated with left-to-right shunting is being cared for by a nurse. What does the nurse consider to be the major characteristic of this type of congenital disorder?

• A. Elevated hematocrit
• B. Severe growth retardation
• C. Clubbing of the fingers and toes
• D. Increased blood flow to the lungs

Correct answer: D

Rationale: The major characteristic of a cardiac malformation associated with left-to-right shunting is increased blood flow to the lungs. This increased flow can lead to pulmonary hypertension and heart failure if left untreated. Elevated hematocrit (Choice A) is not a typical characteristic of this condition. Severe growth retardation (Choice B) is not directly associated with left-to-right shunting. Clubbing of the fingers and toes (Choice C) is more commonly seen in conditions involving chronic hypoxia.
