A client tells the nurse that she had a positive result from an early pregnancy test and, since she knows they can be erroneous, wants to be sure that she is pregnant
Which of the following responses is the most appropriate for the nurse to make? 1. "Most early pregnancy tests are not reliable.".
2. "Pregnancy can be detected 24 to 48 hours after conception, depending on the test.".
3. "Pregnancy cannot be detected before 12 days after conception.".
4. "Most pregnancy tests cannot differentiate between pregnancy and premenstrual hormone levels.".
2. Pregnancy can be detected 24 to 48 hours after conception, depending on the test.
Rationale:
Early pregnancy factor, an immunosuppressant protein, is secreted by the trophoblastic cells of the developing embryo. This factor appears in the maternal serum within 24 to 48 hours after fertilization and forms the basis of a pregnancy test during the first 10 days of development. The nurse should respond that pregnancy can be detected 24 to 48 hours after conception, depending upon the test. It is not true that most early pregnancy tests are not reliable. Pregnancy can be detected before 12 days after conception. Early pregnancy tests assess for the presence of trophoblastic cells and not premenstrual hormone levels.
