Final answer:
This question is about health and the use of a 16 - 18 gauge needle and 2 IV lines.
Step-by-step explanation:
The statement suggests using a larger-sized needle (16 - 18 gauge) and two IV lines due to the concern that one might fail. Therefore, the most appropriate action according to the statement is:
D) Use 2 IV lines, as stated
Using two IV lines with larger-gauge needles as a precautionary measure is indicated in this scenario to ensure successful intravenous access, particularly if there are concerns about the reliability or potential failure of a single IV line. This approach aims to secure adequate access for delivering fluids or medications, especially in situations where immediate or continuous access is critical.
