WILDER, Idaho (AP) - The superintendent of the Wilder School District in southwest Idaho is looking at the district's policies after a woman complained her 15-year-old daughter was given a pelvic exam and a shot of the birth control Depo Provera without the parent's knowledge.

Superintendent Daniel Ariola said that in the last two months the unidentified nurse has taken at least four female students to the Southwest District Health Department where they received contraceptives.

"I want to know what gave her the right," said Lisa Fernandez, whose daughter was one of the students. She said she found out about the treatment for her daughter after obtaining records from the health department.

She said the emergency contact listed on her daughter's records was the school nurse.

Depo Provera provides about three months of protection against pregnancy.

Ariola said Wilder is facing an epidemic of teen pregnancies, and that three years ago 18 students reported they were pregnant.

He said a districtwide survey conducted two years found that nearly half of the kids at the middle and high school levels were sexually active.

"Our kids are coming to us needing help," Ariola told KIVI-TV in Boise.

He said that caused the district to start teaching children to be more responsible, and to provide services to sexually active teens who are too scared to go talk to their parents.

"This is a fine balance that all of us are dealing with," said Ariola. "How far do we go to help kids? You tell me, what do we do when they won't go to mom and dad?"

Another parent who complained about the nurse is Dawn Luna, who said her daughter refused the shots.

"She took the right away from us as parents," said Luna. "She's telling them that if you are having sex, this is what you need to do. If you're not having sex, you'll be having sex soon."
