Question 1 of 5
A nurse is discussing cardiovascular changes during pregnancy with a newly licensed nurse. Which of the following information should the nurse include?

Client at 28 weeks of gestation with history of one elective abortion at 9 weeks, birth of twins at 36 weeks, and spontaneous abortion at 15 weeks
Question 2 of 5
A nurse in a prenatal clinic is reviewing the medical record of a client who is at 28 weeks of gestation. The client's history reveals one pregnancy terminated by elective abortion at 9 weeks, the birth of twins at 36 weeks, and a spontaneous abortion at 15 weeks of gestation. The nurse should document which of the following as the client's present parity?
Correct Answer: D
Rationale: Parity is the number of pregnancies carried to at least 20 weeks. Only the twin birth at 36 weeks counts, so parity is 1. Twins count as one event, and abortions before 20 weeks do not contribute to parity.

Question 3 of 5
A nurse is caring for a female client who is scheduled to have a pelvic examination. The client tells the nurse, 'I'm really nervous because I've never had a pelvic exam before.' Which of the following is an appropriate therapeutic response by the nurse?
Correct Answer: C
