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 nurse is caring for an infant with phenylketonuria (PKU). What diet should the nurse anticipate will be ordered by the health care provider?

• A. Fat-free
• B. Protein-enriched
• C. Phenylalanine-free
• D. Low-phenylalanine

Correct answer: D

Rationale: A low-phenylalanine diet is required for infants with PKU to prevent the buildup of phenylalanine, which can lead to brain damage.

3. A nurse is caring for a child with a diagnosis of acute lymphoblastic leukemia (ALL). What is the priority nursing intervention?

• A. Administering chemotherapy
• B. Preventing infection
• C. Monitoring for signs of bleeding
• D. Providing nutritional support

Correct answer: A

Rationale: The correct answer is A: Administering chemotherapy. In the care of a child with acute lymphoblastic leukemia (ALL), the priority nursing intervention is administering chemotherapy. Chemotherapy is the primary treatment for ALL and plays a crucial role in managing the disease. While preventing infection, monitoring for signs of bleeding, and providing nutritional support are important aspects of caring for a child with ALL, administering chemotherapy takes precedence as it directly targets the cancer cells and aims to induce remission.

4. The nurse is obtaining a health history from parents of a 4-month-old boy with congenital hypothyroidism. What would the nurse most likely assess?

• A. The child's growth is above normal for his age.
• B. The child is active and playful.
• C. The skin appears pink and healthy.
• D. It is difficult to keep the child awake.

Correct answer: D

Rationale: The correct answer is D. Congenital hypothyroidism in infants often leads to lethargy and difficulty staying awake due to low thyroid hormone levels. Assessing the child's ability to stay awake is crucial in identifying signs of hypothyroidism. Choices A, B, and C are incorrect because above-normal growth, being active and playful, and having healthy-looking skin are not typical manifestations of congenital hypothyroidism. Instead, infants with hypothyroidism may exhibit poor weight gain, decreased activity, and dry, pale skin.

5. A 6-month-old infant is brought to the emergency department in severe respiratory distress. A diagnosis of respiratory syncytial virus (RSV) is made and the infant is admitted to the pediatric unit. What should be included in the nursing plan of care?

• A. Place the infant in a warm, dry environment.
• B. Allow parents and siblings to visit.
• C. Maintain standard and contact precautions.
• D. Administer prescribed antibiotics immediately.

Correct answer: C

Rationale: The correct answer is to maintain standard and contact precautions. RSV is highly contagious, primarily spreading through respiratory secretions. Therefore, it is crucial to implement infection control measures to prevent the spread of the virus within the healthcare setting. Option A is incorrect as warmth and dryness are not the primary concern in RSV management. While family support is important, allowing visits may increase the risk of spreading the infection, making option B less appropriate. Option D is incorrect because RSV is a viral infection, and antibiotics are not effective against viruses.
