A woman at low risk and with no family history of breast cancer comes to the clinic and asks the nurse about when she should have her first mammogram.
According to the recommendations of the American Cancer Society, at what age should the woman have her first mammogram?

Choice A rationale
As of my knowledge cutoff in 2021, there is no vaccine available that prevents genital herpes simplex infection from returning.
Choice B rationale
Penicillin is not effective against viral infections such as genital herpes. Antiviral medications are used to manage symptoms and reduce recurrences.
Choice C rationale
This is the most appropriate response. While there is no cure for genital herpes, antiviral medications can help to reduce symptoms and the frequency of recurrences.
Choice D rationale
Having a genital herpes infection does not lead to immunity. The virus remains in the body and can cause recurrent outbreaks.

Choice A rationale
Giving an infant with a positive PKU test a high protein diet is not recommended. This is because phenylalanine, which cannot be broken down by individuals with PKU, is found in high-protein foods.
Choice B rationale
Parents of infants with a positive PKU test should provide the infant with a diet containing small amounts of phenylalanine. This is because while phenylalanine is harmful in large amounts to individuals with PKU, it is still an essential amino acid that the body needs in small amounts.
Choice C rationale
Early introduction of cow’s milk is not necessary before 1 year of age for infants with a positive PKU test. In fact, cow’s milk is high in phenylalanine and should be avoided.
Choice D rationale
Following up with a pediatric cardiologist is not specifically related to the dietary management of PKU. While regular medical supervision is important for children with PKU, it does not necessarily have to be with a cardiologist.
