LVN F looked at the order summary and did not find an order for an IV access, no order for IV flush, and no order for dressing change. She said that if the IV site was not cleaned and dressing changed that the resident could be at risk for infection to IV site. LVN F said that if the IV access was not flushed it could put the resident at risk for infiltration and patency. She explained the process of receiving physician orders for IV antibiotic and placement. She said she would input the order, check for allergies, inform the resident and family of new orders and clarify IV management with physician such as flush, dressing change and IV catheter size. Interview on 8/28/2025 at 4:48 p.m. RN/ADON B said that standing orders for peripheral IVs and PICC (peripherally inserted central catheter) lines (thin flexible tube inserted in the upper arm that is threaded into a large central vein) populate automatically in the system when an IV antibiotic is ordered. He said the system is finicky at times and the order for the flush and maintenance needs to be manually input. RN/DON B said that training on physician orders and computer systems was done upon hire and as needed. He said new orders and medical records are managed by him and he follows up with the nurses. Interview on 8/28/2025 at 5:13 p.m. DON said physician orders are given for antibiotic regimen and that nurses need an order for IV flush and dressing.

PIV to left forearm, flushing well, good patency. No redness, or infiltration noted to site. Dressing clean, dry and intact. 2.) Observation on 08/26/25 at 8:53 a.m. revealed Resident #10 was in her room lying in bed. She had a peripheral intravenous lock (a device that is flushed and locked with saline solution when not in use) covered with a transparent dressing on her left hand. There were no signs or symptoms of infection or infiltration (when fluid leaks out of the vein into surrounding soft tissue) noted at the IV site. Record review of Resident #10's admission record dated 06/04/25 revealed an [AGE] year-old female with diagnosis of Colle's' fracture of right radius (type of wrist fracture that occurs when the distal radius ((the lower end of the radius bone in the forearm)) breaks and bends backward), other fractures of lower end of right radius, unspecified protein-calorie malnutrition, major depressive disorder, and dysphagia (difficulty swallowing food or liquids). Record review of Resident #10's quarterly MDS assessment revealed resident #10's BIMS score was a 2 which indicates severe cognitively impaired. Section O - Special Treatments, Procedures, and Programs revealed Resident #10 was receiving IV medications. Record review of Resident #10's Order Summary Report dated August 2025 revealed Resident #10 had an order for Dextrose Intravenous Solution 5 % (Dextrose) Use 80 ml/hr. intravenously every shift for IV hydration for 2 Days with 2 Liters in total, start date 08/20/25 and end date 08/22/25. Record review of Resident #10's Order Summary Report dated August 2025 lacked evidence of orders for IV insertion, IV dressing changes, and IV flushes. In an interview on 08/26/25 at 9:35 a.m. LVN N stated he was the nurse for Resident #10. LVN N stated that when a nurse received doctor's orders for a resident, it was the responsibility of the nurse to also obtain IV site care or maintenance orders. Such orders included how often to replace or flush the IV catheter. LVN N stated that a negative outcome for not receiving and following through with such orders could cause the IV catheter to become clogged and cause infiltration. He also stated if the IV line was to become clogged, it could cause infection to the IV site. LVN N stated he could not recall when the last IV training was. In an interview on 08/27/25 at 9:25 a.m., the DON stated she did not know why there were no orders in place for IV site care. The DON stated that the nurse that had received the order for IV hydration should have also followed through with orders for IV site care and maintenance. The DON searched through orders on the facility's computer system to verify who had received the IV hydration order. Once the DON verified which nurse received the order, she continued to look for the IV site care orders. The DON admitted there were no other orders pertaining to the IV care and stated, I'm not going to lie and say there is an order. If the order is not in the system, then the order is not there. The DON stated that the negative outcome of not having orders for IV flushes or for changing out the IV catheter could have resulted in infection to the IV site or the IV site having had a blockage. She stated that IV administration class was done annually and as needed.

Observation on 08/26/25 at 8:53 a.m. revealed Resident #10 was in her room lying in bed. She had a peripheral intravenous lock covered with a transparent dressing with no date and no initials on her left hand. There were no signs or symptoms of infection or infiltration noted at the IV site. In an interview on 08/26/25 at 9:35 a.m. LVN N stated he was the nurse for Resident #10. He stated that the nurse who initiated the IV was responsible for labeling the dressing with the date of placement and initials. LVN N stated that it was important to label the IV site to know when the IV was placed or the last time it was changed. He stated that if the IV was not changed within the ordered time, then it could cause an infection. He stated that the last time he had checked the resident's IV site was this morning, at the beginning of his shift. LVN N stated that the IV site should be checked at every shift. The site was to be checked for any signs of infection, the date and signature on the dressing, and check that the saline lock cap was in place. He stated he could not recall when the last training was he had received on IV administration. LVN N confirmed the resident had a peripheral IV lock on her left hand covered with a transparent dressing that was not labeled or dated. In an interview on 08/27/25 at 9:25 a.m., the DON stated she did not know why the dressing label had not been dated and initialed. The DON stated that the nurse that had inserted the IV should have dated and initialed the dressing that was over the IV site. The DON searched through orders on their computer system to verify who had placed the IV, however, she was not able to find the progress note indicating placement. The DON stated that labeling the insertion site dressing was taught in nursing school and every nurse should have known to label it. She stated that the negative outcome of not labeling the dressing was that it could go over the recommended standard time of every 72 hours and could cause infection. She stated that IV administration class was done annually and as needed.
