Professionalism in email communication is paramount in nursing. Emails should be clear, concise, and respectful. Nurses should start with a proper salutation and use a polite tone throughout. It is essential to proofread emails for grammar and spelling errors before sending them. Including a clear subject line helps the recipient understand the purpose of the email immediately. Confidential information should be handled with care, and adherence to HIPAA regulations is necessary to protect patient privacy.
