Correct Answer--A client who is nonimmune to rubella or has a negative or low titer is administered a subcutaneous injection of rubella vaccine or a measles, mumps, and rubella (mmr) vaccine during the postpartum period to protect a subsequent fetus from malformations. the client should not get pregnant for 4 weeks (28 days) following the immunization. (Cannot get during pregnancy) -test after 3 month of live vaccine to make sure it works When is a nonstress test performed in antepartum? and why? Correct Answer-Nonstress test is the most widely used technique for antepartum evaluation of fetal well-being performed during the third trimester. It is a noninvasive procedure that monitors response of the FHR to fetal movement. -asses FHR to fetal movement (mom presses button when baby moves and doctor check FHR) -disadvantages of a NST include a high rate of false nonreactive results with the fetal movement response blunted by sleep cycles of the fetus, fetal immaturity, maternal medications, and nicotine use disorder. -The NST is interpreted as reactive if the FHR accelerates at least 15/min (10/min prior to 32 weeks) for at least 15 seconds (10 seconds prior to 32 weeks) and occurs two or more times during a 20-min period. -Nonreactive NST is a test that does not demonstrate at least two qualifying accelerations in a 20-min window. If this is so, a further assessment, such as a contraction stress test (CST) or BPP, is indicated.
