Correct Answer: C

Rationale: The correct course of action after missing oral contraceptive pills depends on how many pills are missed. If three pills are missed, the client should not 'double up' but rather follow the manufacturer's instructions and use an alternative form of contraception until the next cycle. Taking too many pills at once increases the risk of side effects without restoring contraceptive protection.

Correct Answer: A

Rationale: Continuous abdominal pain and vaginal bleeding in a client with a history of cocaine use suggest abruptio placentae, where the placenta detaches from the uterus prematurely, posing serious risks to both mother and fetus.
