Which of the following is a contraindication for PICC line placement?

The correct choice indicates that a degraded skin condition at the insertion site is a contraindication for PICC line placement. This is important because the skin serves as a primary barrier against infection. If the skin at the insertion site is compromised, it significantly increases the risk of introducing bacteria into the bloodstream during the placement of the catheter. Conditions that can affect the integrity of the skin, such as open wounds, rashes, infections, or other dermatological issues, make the procedure more hazardous. Therefore, evaluating the skin condition before catheter placement is essential for ensuring patient safety and reducing the risk of complications associated with PICC line placement.

In contrast, while diabetes mellitus and obesity can present challenges during procedures or may influence healing and infection risks, they do not inherently preclude PICC line placement. Patients with stable coronary artery disease are generally considered safe for the procedure, as long as they are stable and there are no other significant medical concerns that would pose a greater risk for the procedure.
