PICC PICC Equipment & Device Selection 2

Question 1

Per INS standards, what is the preferred method for PICC external securement?

Accepted Answer

Engineered stabilization device (ESD)

Answer

INS guidelines recommend engineered stabilization devices (ESDs) as first choice because they reduce migration, dislodgement, and infection risk compared to sutures or tape.

Question 2

How often should a transparent semipermeable membrane (TSM) dressing on a PICC site be routinely changed?

Accepted Answer

Every 5–7 days or when soiled, loose, or no longer intact

Answer

TSM dressings should be changed every 5–7 days or immediately if compromised, per CDC and INS guidelines, to maintain site integrity and reduce infection.

Question 3

A chlorhexidine-impregnated dressing is MOST indicated for which PICC patient?

Accepted Answer

A patient at elevated CRBSI risk when standard bundle measures have not sufficiently reduced infection rates

Answer

Chlorhexidine-impregnated dressings are recommended as an additional intervention for high-risk patients when basic CRBSI prevention bundles alone have not achieved adequate infection control.

Question 4

What is the primary mechanical purpose of an external PICC securement device?

Accepted Answer

Prevent catheter migration and accidental dislodgement

Answer

Securement devices anchor the catheter to minimize migration and accidental pull-out, which can cause malposition, extravasation, or dislodgement.

Question 5

Which type of needleless connector was associated with higher CRBSI rates due to complex internal fluid pathways and is no longer recommended?

Accepted Answer

Original negative displacement mechanical valve connector

Answer

Original negative displacement mechanical valve connectors created internal dead space that harbored organisms, leading to higher CRBSI rates and subsequent replacement with improved designs.
