Question 1
A healthy 15-year-old adolescent presents for a sports physical. The patient has never received the human papillomavirus vaccine. How should the APRN counsel the family regarding this specific vaccine series?
▸ Why C is the answer
The human papillomavirus vaccine series requires three distinct doses when initiated at age 15 or older, typically administered at 0, 1 to 2, and 6 months. A two-dose series spaced six months apart is only indicated if the series is initiated before the patient's 15th birthday. Since this patient is already 15, the two-dose options are insufficient for optimal immunogenicity. The three-dose schedule must be spread over six months, making a two-month completion timeline incorrect and ineffective for primary prevention.
🔑 Key takeaway
Initiating the HPV vaccine at age 15 or older requires a three-dose series over six months.
