NURS 3100 Exam 1 Practice

A nurse administers a vaccine to a client. What is the nurse's best understanding as it relates to the manufacture of a vaccine?

1. The vaccine is most commonly synthesized in a laboratory

2. The vaccine is naturally produced in animal cells or microorganisms

3. The vaccine is produced by natural plant extracts in the laboratory

4. The vaccine is produced by a combination of animal and plant products

The correct answer is: The vaccine is naturally produced in animal cells or microorganisms

The correct answer is B because vaccines are most commonly produced using either animal cells or microorganisms. Vaccines can be made from weakened or killed forms of the germs, their toxins, or proteins. This process helps the body's immune system recognize and fight those germs if the person is exposed to them in the future. Options A, C, and D are not accurate because vaccines are not commonly synthesized in a laboratory using plant extracts or a combination of animal and plant products.
