Correct Answer is D
Explanation
During the first week or last week of a 28-day cycle pack of oral contraceptives increases the risk of contraceptive failure. However, the client should take the missed dose as soon as they remember, even if it means taking two pills in one day. After taking the missed dose, the client should continue taking the remaining pills in the pack at the usual time, one pill per day. Due to increased risk of failure, client should use an emergency pill or condom for the next 7 days
A -stopping the pills and switching to a different contraceptive method is not necessary after missing one dose
B –missing a pill does not automatically indicate pregnancy. Testing can be considered in presence of typical signs and symptoms of pregnancy
