Final answer:
The practical nurse should enforce the hospital rules and ask the entire family to leave the room.
Step-by-step explanation:
The practical nurse should enforce the hospital rules and ask the entire family to leave the room. The hospital rules are put in place to ensure the safety and well-being of patients, and overcrowding the room goes against these rules. The nurse can explain the importance of following the rules and suggest alternative ways for the family to support the patient, such as taking turns visiting or utilizing other forms of communication.
