Final answer:
The nurse should plan to administer the MMR (Measles, Mumps, Rubella) immunization to the adolescent.
Step-by-step explanation:
The nurse should plan to administer the MMR (Measles, Mumps, Rubella) immunization to the adolescent.
The MMR vaccine provides protection against measles, mumps, and rubella. Even if the adolescent has received all other recommended immunizations through the age of 6 years, it is important to ensure they are also protected against these three diseases.
By administering the MMR vaccine, the nurse can help prevent the adolescent from contracting measles, mumps, and rubella later in life.
