Nursing Elites

1. What organism is a parasite that causes acute diarrhea?

• A. Shigella organisms
• B. Salmonella organisms
• C. Giardia lamblia
• D. Escherichia coli

Correct answer: C

Rationale: Giardia lamblia is a protozoan parasite known to cause acute diarrhea, often through contaminated water or food. Shigella, Salmonella, and E. coli are bacterial pathogens that also cause diarrhea but are not parasites.

2. The parents of an 8-month-old infant voice concern to the nurse that their infant is not developing motor skills as the infant should. What question would be appropriate for the nurse to ask in determining if their fears are warranted?

• A. Does the infant move a toy back and forth from one hand to the other?
• B. Is the infant able to drink from a cup by oneself?
• C. Is the infant able to hold a pencil and scribble on paper?
• D. Does the infant place toys into a box or container and take them out?

Correct answer: A

Rationale: The correct answer is A. By 8 months, an infant should be able to transfer objects between hands, which is an important motor skill milestone. This action shows coordination and developing fine motor skills. Choices B, C, and D involve more advanced motor skills that are typically not expected at 8 months of age. Drinking from a cup, holding a pencil to scribble, and engaging in purposeful play with toys are skills that develop later in infancy.

3. What disease should be suspected in a 3-day-old infant presenting with abdominal distention, vomiting, and failure to pass meconium?

• A. Pyloric stenosis
• B. Intussusception
• C. Hirschsprung disease
• D. Celiac disease

Correct answer: C

Rationale: Hirschsprung disease should be suspected in a newborn with abdominal distention, vomiting, and failure to pass meconium. This condition arises from a congenital absence of nerve cells in a portion of the colon, leading to severe constipation and intestinal obstruction. Pyloric stenosis typically presents with non-bilious projectile vomiting in the first few weeks of life. Intussusception classically manifests with sudden onset of colicky abdominal pain and currant jelly stools. Celiac disease may present with chronic diarrhea, failure to thrive, and abdominal distention but is less likely in this scenario.

4. 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.

5. The nurse is teaching a client to prevent future urinary tract infections (UTIs). What factor is most important to emphasize as the potential cause?

• A. Poor hygiene
• B. Constipation
• C. Urinary stasis
• D. Congenital anomalies

Correct answer: C

Rationale: Urinary stasis is the most important factor in the development of UTIs because it provides an environment for bacterial growth. While poor hygiene and congenital anomalies are contributing factors, preventing urinary stasis is key in UTI prevention.
