someone with a nosocomial infection should be placed in isolation.
true
false
question 4 (1 point)
listen
flagella are whip - like appendages that help certain bacteria move.
true
false

Explanation:

For Question 3: Nosocomial infections (hospital - acquired infections) do not always require isolation. Isolation is based on the specific pathogen, its mode of transmission, and the patient's immune status. For example, a simple urinary tract infection (a common nosocomial infection) may not need isolation if it is caused by a non - transmissible pathogen.
For Question 4: Flagella are indeed whip - like appendages. They use a motor - like mechanism (rotating at the base) to propel bacteria through liquid environments. This is a well - known and fundamental characteristic of bacterial flagella.

Answer:

Question 3: B. False
Question 4: A. True
