Final answer:
A nurse should document 'a) 1 cup of tea' as 120 mL of fluid for a client's intake, as half a cup of liquid equals approximately 120 mL.
Step-by-step explanation:
The question pertains to documenting a client's fluid intake in a healthcare setting, which is an aspect of patient care in the field of nursing. Specifically, the nurse needs to identify which item from a list corresponds to 120 mL of fluid for accurate intake documentation. The correct answer is a) 1 cup of tea, as 1 cup (8 ounces) of liquid is approximately 237 mL, and therefore, half a cup (0.5 cup) would be around 120 mL. This is in line with dietary sheets that often measure servings of liquids in multiples of 120 mL.
