I am a new grad and I just started my job as RN in LTC. Today was my first day working on my own. I had a pt with almost healed pressure ulcer on his coccyx. The order in MAR was to apply alginate dressing. I asked other nurse if I need to cut the dressing and she said no. The size of the wound 1cm-1cm-0.5 cm. The dressing I found in the treatment card was 4cm-4 cm. i didn't know what to do. So I applied that size of alginate dressing on the coccyx area. I came home and read more about alginate dressing. Next time I would cut it to fit it just for packing. Next dressing change will be tomorrow for this pt. I am worring if alginate dressing will hurt healhy skin around wound. What can happen over night? The wound didn't have any drainage.
