Question

A. 10- to 30-degree angle
B. 45-degree angle
C. 90-degree angle
D. 5- to 10-degree angle

Answer 1

An IV catheter should be inserted at a 10- to 30-degree angle to puncture the skin and vein during insertion in a middle-aged adult. This angle helps to properly insert the catheter and minimize trauma.

Step-by-step explanation:

When inserting an IV catheter in a middle-aged adult, the recommended angle for puncturing the skin and vein is at a 10- to 30-degree angle. This technique helps in ensuring that the catheter enters the vein properly without causing excessive trauma to the vein or surrounding tissue. The precise angle may vary based on the patient's anatomy and the clinician's experience, but it generally falls within this range for successful catheter insertion.
