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.

Correct Answer: A

Rationale: The correct answer is A: Sitting independently. By 11 months, most infants can sit independently. This milestone usually precedes walking, which typically occurs closer to 12 months. Turning a doorknob and building a tower of four cubes involve more complex motor skills that are typically achieved later in development. Therefore, at 11 months, sitting independently is the milestone that the nurse would expect an infant to have achieved.

Correct Answer: C

Rationale: A heart rate of 120 beats per minute is high for a preschool-aged child and may indicate an underlying issue that requires further assessment. A respiratory rate of 20 breaths per minute (choice A) is within the normal range for preschool children. Similarly, a heart rate of 89 beats per minute (choice B) falls within the expected range. A respiratory rate of 24 breaths per minute (choice D) is slightly elevated but may not be as concerning as a heart rate of 120 beats per minute.
