Nursing Elites

1. An infant is diagnosed with a tracheoesophageal fistula. Which assessment finding should the nurse expect?

• A. Jaundice
• B. Hyperactive bowel sounds
• C. Absence of sucking, vomiting
• D. Coughing, with excessive secretion

Correct answer: D

Rationale: Coughing with excessive secretion is a common sign of tracheoesophageal fistula. In this condition, the connection between the trachea and esophagus allows saliva and food to enter the airways, leading to coughing and excessive secretions. Choice A, jaundice, is not typically associated with tracheoesophageal fistula. Hyperactive bowel sounds (Choice B) are more likely seen in conditions like gastroenteritis. Absence of sucking and vomiting (Choice C) is not a typical finding related to tracheoesophageal fistula.

2. Physiologically, the child compensates for fluid volume losses by which mechanism?

• A. Inhibition of aldosterone secretion
• B. Hemoconcentration to reduce cardiac workload
• C. Fluid shift from interstitial space to intravascular space
• D. Vasodilation of peripheral arterioles to increase perfusion

Correct answer: C

Rationale: In response to dehydration, the body compensates by shifting fluids from the interstitial spaces to the intravascular space to maintain blood pressure and perfusion to vital organs. Hemoconcentration and vasoconstriction are other compensatory mechanisms but are less immediate.

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. What type of dehydration occurs when the electrolyte deficit exceeds the water deficit?

• A. Isotonic dehydration
• B. Hypotonic dehydration
• C. Hypertonic dehydration
• D. Hyperosmotic dehydration

Correct answer: B

Rationale: Hypotonic dehydration occurs when the loss of electrolytes exceeds the loss of water, leading to a decrease in plasma osmolarity. This often occurs when sodium loss is greater than water loss, as in diarrhea or vomiting.

5. An effective means of establishing rapport with the hospitalized pre-schooler is through:

• A. Lengthy discussion
• B. Explanation with drawings and models
• C. Play
• D. Silence

Correct answer: C

Rationale: Play is an effective way to communicate and build rapport with young children, especially pre-schoolers. It helps them feel comfortable, express themselves, and establish a connection with the caregiver. Lengthy discussions may not be suitable for their age and attention span, while explanation with drawings and models can enhance communication but may not engage them as effectively as play. Silence, on the other hand, may create a sense of unease or lack of interaction for pre-schoolers.
