Martha: Vascular Access CNS

Martha is a vascular access clinical nurse specialist you can ask at the bedside. Built by Vascular Access & Consulting — a mobile team that places PICCs, midlines and ultrasound-guided IVs in skilled nursing, long-term care and home settings every day — Martha answers the questions nurses actually face, grounded in the published standards and cited.

ASK HER ANYTHING VASCULAR
• Device selection: midline vs PICC vs peripheral IV, and why
• Medication compatibility: pH, osmolarity, vesicant status
• Occlusions, resistance, no blood return — what to do and what never to do
• CLABSI prevention, hub scrub, dressing changes, ANTT
• PICC in CKD: eGFR, vein preservation, KDOQI and Fistula First
• MAGIC criteria and where the evidence has moved since 2015
• Scope-of-practice questions (RN vs LPN/LVN) — and when to check your state act

GROUNDED, NOT GENERIC
Martha's answers draw on the INS Infusion Therapy Standards of Practice (9th ed., 2024), MAGIC, CDC CLABSI-prevention guidance, NKF KDOQI, and the contemporary midline literature — with the citation, so you can look it up and bring it to your team.

BUILT FOR A NURSE WORKING ALONE
Lead with the answer, then the "why." Practical steps you can act on now, clear flags when something is unsafe, and a plain "stop and call the provider" when that is the right move.
