Which of the following findings in an 8-week gestation client, G2 P1001, should the nurse highlight for the nurse midwife? Select all that apply.
- A. Body mass index of 17 kg/m².
- B. Rubella titer of 1:8.
- C. Blood pressure of 100/60 mm Hg.
- D. Hematocrit of 30%.
Correct Answer: A
Rationale: A low BMI, low rubella titer, and low hematocrit are all concerning findings that should be highlighted for further evaluation. A blood pressure of 100/60 mm Hg is within normal limits.

- A. Leg cramps.
- B. Varicose veins.
- C. Hemorrhoids.

A nurse is caring for a laboring person and is monitoring for signs of fetal distress. Which finding is the most concerning in this situation?
- A. Late decelerations
- B. Bradycardia
- C. Tachycardia
- D. Variable decelerations
Correct Answer: A
Rationale: The correct answer is A: Late decelerations. Late decelerations indicate uteroplacental insufficiency, which can lead to fetal hypoxia and distress. This is the most concerning finding as it indicates a problem with oxygen delivery to the fetus. Bradycardia (B) and Tachycardia (C) can also be concerning, but late decelerations are more specific to fetal distress. Variable decelerations (D) are caused by cord compression and are concerning but not as indicative of fetal distress as late decelerations.
What is the purpose of the Leopold's maneuver in labor and delivery?
- A. to assess fetal presentation and position
- B. to assess fetal position and the location of the placenta
- C. to assess uterine tone and fetal heart rate
- D. to assess the fetal heart rate pattern
Correct Answer: A
Rationale: The purpose of Leopold's maneuver in labor and delivery is to assess fetal presentation and position. Step 1 evaluates the fundal grip to determine the fetal part. Step 2 assesses the sides of the abdomen to identify the fetal back. Step 3 determines the presenting part and position. Step 4 confirms the presenting part and its mobility. This systematic approach helps determine the position of the fetus in the uterus. Choices B, C, and D are incorrect as they do not align with the specific purpose of Leopold's maneuver, which is primarily focused on assessing fetal presentation and position.
