Final answer:
Nurse managers prefer email communication with multiple recipients for its ease of distribution, the ability to maintain a written record, and the added privacy and confidentiality it offers.
Step-by-step explanation:
There are several reasons why a nurse manager might prefer email when communicating with multiple recipients. Firstly, emails allow for easy distribution to multiple recipients at once, saving time and effort.
Additionally, email provides a written record that can be copied and pasted, ensuring consistent communication and reducing the chance of misunderstandings.
Lastly, email offers a level of privacy and confidentiality that physical letters may not provide, as emails can be sent securely and accessed only by intended recipients.
