Final answer:
The priority nursing diagnosis for an older female client with atrophic vaginitis and perineal cutaneous candidiasis is Impaired comfort.
Step-by-step explanation:
The priority nursing diagnosis for an older female client admitted with atrophic vaginitis and perineal cutaneous candidiasis would be Impaired comfort. Vaginitis, characterized by vaginal inflammation, itching, and pain, can cause significant discomfort for the client. The presence of perineal cutaneous candidiasis, a fungal infection, can further contribute to the discomfort experienced.
It is important for the nurse to prioritize interventions that promote comfort and alleviate symptoms. This may include providing topical treatments, such as antifungal creams, to address the candidiasis. Additionally, educating the client on proper hygiene practices and ways to manage symptoms can also help improve comfort.
