The DON stated the nurses should have signed the controlled log so that the medication were accounted, and the nurses knew the medications were complete when they come to work. 2. Review of the facility's P&P titled IIB5: Eye Drop Administration revised 10/2019 showed to administer ophthalmic solution/suspension into the eye in a safe, accurate, and effective manner. While the eye is closed, use one finger to compress the tear duct in the inner corner of the eye for one to two minutes. This reduces systemic absorption of the medication. Alternatively, the resident may keep his/her eyes closed for approximately three minutes. On 3/19/25 at 0908 hours, a medication administration observation was conducted with LVN 9. LVN 9 administered the brimonidine tartrate ophthalmic solution (an eye drop medication for glaucoma), one drop in both eyes of Resident 71. After instilling the eye drop solution to Resident 71's eyes, LVN 9 instructed the resident to close his eyes for one minute. However, Resident 9 opened his eyes immediately and started talking to LVN 9 informing LVN 9 that he wanted some sugar. LVN 9 left Resident 71's room to get the requested sugar. Resident 71 was observed opening and closing his eyes intermittently and wiped his eyes. Medical record review of Resident 71 was initiated on 3/19/25.

F 0880 Level of Harm - Minimal harm or potential for actual harm Residents Affected - Few 3. According to the CDC, EBP are an infection control intervention designed to reduce transmission of MDROs in nursing homes. EBP involves gown and glove use during high-contact resident care activities for residents known to be colonized or infected with a MDRO as well as those at increased risk of MDRO acquisition. Review of the facility's signage for EBP showed everyone must clean their hands, including before entering and when leaving the room. It also showed for the providers and staff must wear gloves and gown for the following high-contact resident care activities: dressing, bathing/ showering, transferring, changing linens, providing hygiene, changing briefs, or assisting with toileting, device care or use: central line, urinary catheter, feeding tube, tracheostomy, and wound care: any skin opening requiring a dressing. Review of the facility's P&P titled IPCP Standard and Transmission-Based Precautions revised date 3/2024 showed EBP: used in conjunction with standard precautions and expand the use of PPE through the use of gown and gloves during high-contact resident care activities that provide opportunities for indirect transfer of MDROs to staff hands and clothing then indirectly transferred to residents or from resident-to-resident. (e.g., residents with wounds and indwelling medical devices are at especially high risk of both acquisition of and colonization with MDROs). Medical record review for Resident 24 was initiated on 3/17/25. Resident 24 was admitted to the facility on [DATE], and readmitted on [DATE]. Review of Resident 24's H&P examination dated 7/24/23, showed Resident 24 had no capacity to understand and make decisions.
