Nursing Elites

1. The nurse is caring for a child with acute postinfectious glomerulonephritis. Which of the following best describes the pathophysiology of acute postinfectious glomerulonephritis?

• A. Occurs after a urinary tract infection
• B. Occurs after a streptococcal infection
• C. Associated with renal vascular disorders
• D. Is caused by E. coli

Correct answer: B

Rationale: The correct answer is B: 'Occurs after a streptococcal infection.' Acute postinfectious glomerulonephritis often occurs after an infection with certain strains of streptococcus bacteria, specifically group A streptococcus. The body’s immune response to the infection leads to inflammation and damage in the kidneys. Choices A, C, and D are incorrect because acute postinfectious glomerulonephritis is primarily associated with streptococcal infections, not urinary tract infections, renal vascular disorders, or E. coli.

2. The nurse is preparing to feed a 10-month-old child diagnosed with failure to thrive (FTT). Which actions should the nurse plan to implement?

• A. Be persistent.
• B. Introduce new foods slowly.
• C. All are correct
• D. Maintain a calm, even temperament.

Correct answer: C

Rationale: Persistence in feeding, introducing new foods slowly, and maintaining a calm temperament are key strategies in managing FTT. A stimulating atmosphere may overwhelm the child and should be minimized during feeding times.

3. The nurse is planning a teaching session to adolescents about deaths by unintentional injuries. Which should the nurse include in the session with regard to deaths caused by injuries?

• A. More deaths occur in males
• B. More deaths occur in females
• C. The pattern of deaths does not vary according to age and sex
• D. The pattern of deaths does not vary widely among different ethnic groups

Correct answer: A

Rationale: More deaths due to unintentional injuries occur in males, which may be due to higher risk-taking behaviors.

4. 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.

5. What is the most effective way to prevent sudden infant death syndrome (SIDS)?

• A. Use a firm mattress
• B. Place the baby on their back to sleep
• C. Keep the room warm
• D. Breastfeed exclusively

Correct answer: B

Rationale: The correct answer is to place the baby on their back to sleep. This position is the most effective way to prevent sudden infant death syndrome (SIDS) according to research and recommendations from healthcare providers. Choice A, using a firm mattress, is important for infant safety but not as directly related to preventing SIDS. Keeping the room warm, as mentioned in choice C, is not recommended as it may increase the risk of SIDS. While breastfeeding has many benefits, choice D, breastfeeding exclusively is not the most effective method for preventing SIDS.
