The nurse is assessing a client who reports they have missed three menstrual periods and now visits the prenatal clinic. The client reports having enlarged breasts, urinary frequency, and nausea and is concerned that they may be pregnant. What is the best response by the nurse?

It sounds like you are definitely pregnant.Congratulations!

You might be pregnant, but we will have to do a pregnancy test and measure your fundus to be sure.

These signs could be caused by other things, so we will need to hear the fetal heartbeat to be certain.

You should come back in 4 weeks to do further testing.
