1. 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.

2. A child diagnosed with aplastic anemia is admitted to the hospital. The parents ask the nurse what aplastic anemia is. Which response by the nurse is accurate?

• A. Aplastic anemia causes a proliferation of white blood cells.
• B. Aplastic anemia is characterized by abnormally shaped red blood cells.
• C. Aplastic anemia is caused by the bone marrow producing inadequate cells.
• D. Aplastic anemia is a disorder that occurs after a viral illness.

Correct answer: C

Rationale: Aplastic anemia is a condition where the bone marrow fails to produce sufficient red blood cells, white blood cells, and platelets, leading to pancytopenia. This can result in fatigue, infections, and bleeding tendencies. It is not characterized by abnormal red blood cell shapes, but rather by a reduction in the production of blood cells. Therefore, the accurate response is that aplastic anemia is caused by the bone marrow producing inadequate cells. Choices A and B are incorrect as aplastic anemia does not cause a proliferation of white blood cells or involve abnormally shaped red blood cells. Choice D is incorrect as aplastic anemia is not typically a disorder that occurs after a viral illness.

3. What is the most common complication following surgical correction of esophageal atresia with tracheoesophageal fistula in infants?

• A. Gastroesophageal reflux
• B. Respiratory distress
• C. Stricture formation
• D. Aspiration pneumonia

Correct answer: C

Rationale: The most common complication following surgical correction of esophageal atresia with tracheoesophageal fistula in infants is stricture formation. This complication occurs due to the healing process after surgery, leading to the narrowing of the esophagus. Gastroesophageal reflux (Choice A) can be a concern but is not the most common complication. Respiratory distress (Choice B) may happen but is not the primary complication. Aspiration pneumonia (Choice D) is a risk but is typically not as common as stricture formation in these cases.

4. At a well-visit, a mother voices concern that her 30-month-old has a smaller vocabulary than other children in his daycare. The nurse should:

• A. Admit the child to the hospital
• B. Assess the child for other age-appropriate development
• C. Suggest that the child is hearing impaired
• D. Explain that the child has a significant developmental delay

Correct answer: B

Rationale: When a parent expresses concern about a child's development, it is essential to conduct a comprehensive assessment of all areas of development before jumping to conclusions. Choosing option B allows the nurse to evaluate the child for other age-appropriate developmental milestones to determine if there are any delays or concerns. Admitting the child to the hospital (option A) is not necessary at this point and may cause unnecessary stress. Suggesting hearing impairment (option C) without proper evaluation can lead to misdiagnosis. Explaining a significant developmental delay (option D) should only be done after a thorough assessment and diagnosis.

5. The nurse is testing an infant's visual acuity. By which age should the infant be able to fix on and follow a target?

• A. 1 month
• B. 1 to 2 months
• C. 3 to 4 months
• D. 6 months

Correct answer: C

Rationale: By 3 to 4 months of age, an infant should be able to fix on and follow a target, indicating proper visual development.
