RNC-OB REAL final EXAM 2025/2026 ACCURATE FALL-SPRING SESSION ORIGINAL COMPLETE QUESTION AND ANSWER GRADED A+ 300 QUESTIONS A pregnant woman with cervical funneling is at risk for a. hemorrhage b. miscarriage/preterm delivery c. prolonged labor – Correct Answer :B risk for cervical incompetence, which means that the muscles of the cervix are weak and the pressure of the growing fetus may produce early effacement and dilation before contractions begin, resulting in miscarriage or preterm delivery during the second and third trimester. A normal cervix is 30 mm long; cervical incompetence means the cervix is less than 25 mm long at 24 weeks or less of gestation. The shorter the cervix, the greater the risk of preterm birth. A+ TEST BANK 1 RNC-OB REAL EXAM 2025 At 4 weeks gestation, two beta hCG values taken 48 hours apart show decreasing values. This suggests a. normal pregnancy b. miscarriage/ectopic pregnancy c. inaccurate calculation of inception – Correct Answer :B Beta hCG is produced by the trophoblast or placenta and accurately indicates the presence of pregnancy. For the first 10 days of pregnancy, the levels double every 2 days and then continue to increase until peaking at 60-90 days after conception, so a stable to falling level indicates that the pregnancy is not progressing. A neonate's umbilical cord blood values were pH 7.16, pO2 18 mmHg, and pCO2 55 mmHg, with base excess of 11 mEq/L, indicating a. normal values b. respiratory acidosis c. metabolic acidosis – Correct Answer :C -Respiratory acidosis: pH < 7.25, pO2 varies, pCO2 > 50 mmHg, Base excess < 10 mEq/L -Metabolic acidosis: pH < 7.25, pO2 < 20 mmHg, pCO2 44-55 mmHg, base excess > 10 mEq/L A+ TEST BANK 2 RNC-OB REAL EXAM 2025 If fetal scalp blood sampling is done because of an unusual fetal heart rate pattern, a pH of 7.2 indicates a. the need for immediate delivery b. a normal value c. the need for repeat sampling in 20 minutes – Correct Answer :A ...usually either with forceps delivery if criteria are met or with cesarean. A normal fetal pH is 7.25 or greater. If the level is 7.21-7.24, repeat fetal scalp blood sampling may be done every 20 minutes until there is a changes in the FHR pattern for better or worse, indicating the need for delivery Repeated variable decelerations of fetal heart rate during labor suggest a. normal variations b. umbilical cord occlusion c. uteroplacental insufficiency - Correct Answer :B The fetus may roll on the cord or the cord may be around the neck, resulting in occlusion during uterine contractions Repeated variable decelerations may also indicate a short cord or occult prolapse of the cord. If the variable decelerations occur occasionally without pattern, they are usually not of concern, but if they are repeated and worsen as labor progresses, the fetus is at risk. If the variable decelerations are in response to rupturing the membranes, changing the mother's position may alleviate the decelerations.
