1. Which laboratory test would be most important for the nurse to assess when caring for a toddler suspected of having cystic fibrosis?

• A. Liver enzymes
• B. Serum calcium
• C. Sweat chloride test
• D. Urine creatinine

Correct answer: C

Rationale: The sweat chloride test is the primary diagnostic test for cystic fibrosis. Cystic fibrosis is characterized by abnormal transport of chloride and sodium across epithelial cell membranes, leading to increased chloride in sweat. This test is crucial for diagnosing cystic fibrosis in suspected cases. Liver enzymes (Choice A), serum calcium (Choice B), and urine creatinine (Choice D) are not specific tests for cystic fibrosis and would not provide the necessary information for diagnosis in this case.

2. The nurse is planning to counsel family members as a group to assess the family's group dynamics. Which theoretical family model is the nurse using as a framework?

• A. Feminist theory
• B. Family stress theory
• C. Family systems theory
• D. Developmental theory

Correct answer: C

Rationale: Family systems theory views the family as an interconnected system where changes in one member affect the entire family, making it ideal for assessing group dynamics.

3. What laboratory finding should the nurse expect in a child with an excess of water?

• A. Decreased hematocrit
• B. High serum osmolality
• C. High urine specific gravity
• D. Increased blood urea nitrogen (BUN)

Correct answer: A

Rationale: Water excess typically leads to hemodilution, resulting in a decreased hematocrit. High serum osmolality and specific gravity would indicate dehydration, while elevated BUN could suggest renal impairment or dehydration, not fluid overload.

4. The nurse is preparing to admit a child to the hospital with a diagnosis of minimal change nephrotic syndrome. The nurse understands that the peak age at onset for this disease is what?

• A. 2 to 3 years
• B. 4 to 5 years
• C. 6 to 7 years
• D. 8 to 9 years

Correct answer: B

Rationale: The peak age for the onset of minimal change nephrotic syndrome (MCNS) is typically between 4 and 5 years old. MCNS is the most common cause of nephrotic syndrome in children, particularly within this age range.

5. When assessing a child with chronic renal failure, which clinical manifestations would the nurse expect to find?

• A. Uremic frost
• B. Hypotension
• C. Massive hematuria
• D. Severe metabolic acidosis

Correct answer: A

Rationale: When assessing a child with chronic renal failure, the nurse would expect to find uremic frost as a clinical manifestation. Uremic frost, a white powdery deposit of urea on the skin, occurs in severe cases of chronic renal failure due to the accumulation of urea and other waste products in the blood. Hypotension and massive hematuria are less common in chronic renal failure, while severe metabolic acidosis is typically mild to moderate and not a prominent clinical manifestation.
