Nursing Elites

1. Which laboratory test would be most important for the nurse to assess when caring for a toddler suspected of having cystic fibrosis?

• A. Liver enzymes
• B. Serum calcium
• C. Sweat chloride test
• D. Urine creatinine

Correct answer: C

Rationale: The sweat chloride test is the primary diagnostic test for cystic fibrosis. Cystic fibrosis is characterized by abnormal transport of chloride and sodium across epithelial cell membranes, leading to increased chloride in sweat. This test is crucial for diagnosing cystic fibrosis in suspected cases. Liver enzymes (Choice A), serum calcium (Choice B), and urine creatinine (Choice D) are not specific tests for cystic fibrosis and would not provide the necessary information for diagnosis in this case.

2. Following treatment for iron deficiency anemia, the physician orders lab tests. Which lab value would indicate an improvement in the child’s condition?

• A. Low hemoglobin
• B. Normal platelet count
• C. High reticulocyte count
• D. Low hematocrit

Correct answer: C

Rationale: A high reticulocyte count indicates that the bone marrow is producing more red blood cells, which is a sign of recovery from anemia as the body replenishes its iron stores and increases hemoglobin levels. Low hemoglobin (Choice A) would indicate ongoing anemia rather than improvement. A normal platelet count (Choice B) and low hematocrit (Choice D) are not specific indicators of improvement in iron deficiency anemia.

3. When should the nurse instruct parents to administer a daily proton pump inhibitor to their child with gastroesophageal reflux?

• A. At bedtime
• B. With a meal
• C. Midmorning
• D. 30 minutes before breakfast

Correct answer: D

Rationale: Proton pump inhibitors (PPIs) like omeprazole or lansoprazole are most effective when given 30 minutes before breakfast. This timing allows the medication to inhibit the proton pumps in the stomach that produce acid, providing better symptom control throughout the day. Administering the PPI at bedtime (choice A) may not be as effective as giving it before breakfast due to the timing of peak acid production during the day. Giving it with a meal (choice B) might affect the absorption and effectiveness of the medication. Midmorning administration (choice C) is not the recommended time for optimal PPI efficacy.

4. What diet is most appropriate for the child with chronic renal failure (CRF)?

• A. Low in protein
• B. Low in vitamin D
• C. Low in phosphorus
• D. Supplemented with vitamins A, E, and K

Correct answer: C

Rationale: A low-phosphorus diet is important in managing chronic renal failure to prevent hyperphosphatemia and its associated complications, such as bone disease. Protein intake should be controlled but not necessarily low, and vitamin D supplementation is often required, not reduced.

5. Which immunization should the nurse include in a teaching session for parents of toddler-age clients to decrease the risk for epiglottitis?

• A. Hepatitis B
• B. Polio
• C. Measles, mumps, and rubella (MMR)
• D. Hemophilus influenzae type B (Hib)

Correct answer: D

Rationale: The correct answer is D, Hemophilus influenzae type B (Hib) vaccine. Hib vaccine is crucial in preventing epiglottitis, a serious respiratory condition caused by Haemophilus influenzae type b bacteria. This vaccine is recommended for toddlers to protect them from developing epiglottitis. Choices A, B, and C are incorrect because while they are important vaccines for children, they do not specifically target the prevention of epiglottitis, unlike the Hib vaccine.
