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.

A new mom is ready to introduce solid foods to her infant. Which food would you recommend starting with?
- A. Meat
- B. Rice cereal
- C. Fruits
- D. Vegetables
Correct Answer: B
Rationale: The correct answer is B: Rice cereal. Rice cereal is typically the first solid food introduced to infants because it is easy to digest and unlikely to cause an allergic reaction. Starting with rice cereal helps assess the baby's readiness for solid foods and reduces the risk of allergic responses. Choice A (Meat) is not recommended as the initial solid food due to its higher allergenic potential. Choices C (Fruits) and D (Vegetables) are also not usually recommended as the first solid food, as they may be more challenging for infants to digest compared to rice cereal.
