Final answer:
Instructions for a patient who missed three tablets of Ortho Tri-Cyclen Lo in the second week of her cycle and how to prevent pregnancy.
Step-by-step explanation:
If the patient missed three tablets of Ortho Tri-Cyclen Lo during the second week of her cycle, she should follow the following instructions:
- Take one tablet as soon as she remembers.
- Take one tablet on the next day.
- Continue taking one tablet every day at the same time.
It is important for her to use additional contraception, such as condoms, for the next 7 days to prevent pregnancy. If she had unprotected sex during the missed week, she may be at risk of pregnancy and should consult her healthcare provider for further guidance.
