A nurse is reviewing the health history of a client who has a new prescription for a combined oral contraceptive (COC). The nurse recognizes that which of the following client medications can interfere with the effectiveness of the COC?

The correct answer is B. Anticonvulsants. Anticonvulsants can interfere with the effectiveness of a combined oral contraceptive (COC)10111213. These medications can increase the metabolism of COCs, thereby reducing their effectiveness and potentially leading to contraceptive failure.

The correct answer is Choice D

Choice A rationale: Lanugo, very fine hairs, begin to cover the baby's body around week 20, not week 36. These hairs help protect the skin and usually disappear before birth. By week 36, the lanugo has mostly disappeared, and the baby is almost fully developed.

Choice B rationale: The sex of the baby is determined at conception based on the chromosomes carried by the sperm and egg. However, the external genitalia do not become distinguishable until around week 12 of pregnancy, making week 8 too early for sex determination.

Choice C rationale: Most women first feel fetal movements, known as quickening, between weeks 18 and 22, not week 24. This can vary based on individual factors, but week 24 is generally later than the typical range for first fetal movements.

Choice D rationale: The baby's heartbeat can usually be heard using a Doppler stethoscope by around 12 weeks of pregnancy. This marks a significant milestone and reassures expectant parents about their baby's health and development at this early stage
