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. Which is the leading cause of death in infants younger than 1 year in the United States?

• A. Congenital anomalies
• B. Sudden infant death syndrome
• C. Disorders related to short gestation and low birth weight
• D. Maternal complications specific to the perinatal period

Correct answer: A

Rationale: Congenital anomalies are the leading cause of death in infants younger than 1 year in the United States.

3. Which laboratory value at the time of diagnosis should the nurse anticipate would determine the worst prognosis for a child with leukemia?

• A. Slow response to chemotherapy
• B. Platelets of 150,000/mcL
• C. Leukocytes less than 10,000/mcL
• D. Leukocytes of 275,000/mcL

Correct answer: D

Rationale: A high white blood cell count (leukocytes of 275,000/mcL) at diagnosis is associated with a worse prognosis in leukemia because it indicates a more aggressive disease with a higher tumor burden. Slow response to chemotherapy (choice A) is a consequence of the aggressive disease and not a determining factor at diagnosis. Platelets of 150,000/mcL (choice B) and leukocytes less than 10,000/mcL (choice C) are within normal ranges and not indicative of a worse prognosis in leukemia.

4. What is the most common cause of abdominal pain in school-aged children?

• A. Gastroenteritis
• B. Constipation
• C. Appendicitis
• D. Irritable bowel syndrome

Correct answer: B

Rationale: Constipation is the most common cause of abdominal pain in school-aged children. It is often due to dietary factors such as low fiber intake or insufficient fluid consumption. Chronic constipation can lead to complications like fecal impaction and soiling, highlighting the importance of early recognition and treatment. Gastroenteritis, although common, typically presents with diarrhea and vomiting. Appendicitis is more common in adolescents and typically presents with right lower quadrant pain. Irritable bowel syndrome is less common in children and is characterized by recurrent abdominal pain associated with defecation.

5. Physiological anorexia in toddlerhood occurs because of:

• A. Decreased appetite and decreased nutritional need
• B. Decreased appetite and increased nutritional need
• C. Increased appetite and lack of food preferences
• D. Increased appetite and strong food preferences

Correct answer: A

Rationale: Physiological anorexia in toddlers occurs due to a decreased appetite as growth rates slow down. Choice A is correct because it aligns with the concept that toddlers experience a natural decrease in appetite as their growth rate decreases. Choices B, C, and D are incorrect because they suggest increased appetite or other factors not associated with physiological anorexia in toddlerhood.
