Nursing Elites

1. Which condition is most commonly associated with a 'sunset sign' in infants?

• A. Hydrocephalus
• B. Meningitis
• C. Cerebral palsy
• D. Encephalitis

Correct answer: A

Rationale: The 'sunset sign,' characterized by downward-driven eyes, is most commonly associated with hydrocephalus. This condition causes increased intracranial pressure, leading to the eyes appearing to be forced downward. Meningitis (choice B) typically presents with symptoms such as fever, headache, and a stiff neck, but not the 'sunset sign.' Cerebral palsy (choice C) is a group of disorders affecting movement and muscle coordination, not directly related to the 'sunset sign.' Encephalitis (choice D) is inflammation of the brain, which can cause symptoms like fever, headache, and confusion, but not the specific downward eye gaze seen in the 'sunset sign.'

2. What is the primary consideration of susceptibility to infections in neonates?

• A. Increased humoral immunity
• B. Overwhelming anti-inflammatory response
• C. Diminished nonspecific and specific immunity
• D. Excessive levels of immunoglobulin A and immunoglobulin M

Correct answer: C

Rationale: The primary consideration of susceptibility to infections in neonates is their diminished nonspecific and specific immunity. Neonates lack the ability to mount a robust immune response, making them vulnerable to infections. Choice A is incorrect because neonates do not have increased humoral immunity; rather, their humoral immunity is diminished. Choice B is incorrect as neonates do not have an overwhelming anti-inflammatory response; instead, their immune responses are generally weakened. Choice D is incorrect because neonates have diminished or absent levels of immunoglobulin A and immunoglobulin M, contributing to their susceptibility to infections.

3. 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.

4. The nurse is assessing a 3-year-old African American child whose height and weight are at the 20th percentile on the growth chart. What should the nurse recognize?

• A. The data suggest the child requires nutritional intervention
• B. The NCHS charts are accurate for U.S. African American children
• C. A correction factor is used for nonwhite ethnic groups
• D. No assessment can be made until several measurements are plotted over time

Correct answer: B

Rationale: The NCHS growth charts serve as reference guides for all racial or ethnic groups, including African American children. The 20th percentile for height and weight does not indicate nutritional failure but provides a reference point for ongoing assessment. Choice A is incorrect because being at the 20th percentile does not automatically imply the need for nutritional intervention. Choice C is incorrect as there is no correction factor specifically used for nonwhite ethnic groups in this context. Choice D is incorrect as a single measurement at the 20th percentile can provide valuable information for assessment.

5. What condition is often associated with severe diarrhea?

• A. Metabolic acidosis
• B. Metabolic alkalosis
• C. Respiratory acidosis
• D. Respiratory alkalosis

Correct answer: A

Rationale: Severe diarrhea can lead to a loss of bicarbonate, resulting in metabolic acidosis. This is a common complication of prolonged or severe diarrhea, especially in children.
