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 assessing a child's capillary refill time. This can be accomplished by doing what?

• A. Inspect the chest
• B. Auscultate the heart
• C. Palpate the apical pulse
• D. Palpate the nail bed with pressure to produce a slight blanching

Correct answer: D

Rationale: Capillary refill time is assessed by applying pressure to the nail bed and observing how quickly the color returns, indicating peripheral circulation status.

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. Why is knowledge of developmental theories useful for the nurse?

• A. Allows the nurse to know exactly what to do when caring for pediatric patients
• B. Is predictable and aids in controlling the child’s development
• C. Is a set of facts that each child follows in a prescribed method
• D. Provides a framework to guide the nurse in caring for the patient

Correct answer: D

Rationale: The correct answer is D. Understanding developmental theories helps nurses anticipate and plan appropriate care based on the child’s developmental stage. Choice A is incorrect because developmental theories provide a framework but do not dictate exact actions. Choice B is incorrect as developmental processes are not entirely predictable and are not meant to control a child’s development. Choice C is incorrect as developmental theories are not a strict set of facts that all children follow in a prescribed manner, but rather guidelines for understanding and supporting a child's growth and development.

5. Which pediatric condition is characterized by a "string sign" on an upper GI series?

• A. Intussusception
• B. Hypertrophic pyloric stenosis
• C. Hirschsprung disease
• D. Meckel diverticulum

Correct answer: B

Rationale: The correct answer is B: Hypertrophic pyloric stenosis. The "string sign" is associated with hypertrophic pyloric stenosis, a condition where the pyloric canal is narrowed, leading to gastric outlet obstruction. Intussusception (choice A) typically presents with colicky abdominal pain and currant jelly stools. Hirschsprung disease (choice C) is characterized by the absence of ganglion cells in the distal colon. Meckel diverticulum (choice D) is a congenital outpouching of the small intestine that can present with painless rectal bleeding.
