Correct Answer is B

Explanation

Choice A rationale

Administering oxygen would not be the priority as the fetal heart rate is normal and there are no abnormal fetal movements or signs of distress. Oxygen administration is typically reserved for cases where there is evidence of fetal hypoxia or distress.

Choice B rationale

Checking cervical dilation is essential as it provides critical information about the progress of labor and helps in determining the next steps in management. It ensures that the labor is progressing appropriately and identifies if there is a need for any medical interventions.

Choice C rationale

Starting an intravenous fluid bolus would not be the first action in this scenario as the client does not show signs of dehydration or hypotension. Fluid bolus is generally reserved for cases where there is evidence of hypovolemia or to support hemodynamic stability.

Choice D rationale

Preparing for immediate delivery is not necessary at this stage as there are no signs of fetal distress or urgent complications. The client is only 37 weeks gestation and regular assessment is crucial to ensure timely and appropriate interventions without premature actions.

Correct Answer is ["6"]

Explanation

Step 1 is: Determine the oxytocin concentration in milliunits per mL:. 20,000 milliunits ÷ 1,000 mL = 20 milliunits/mL.

Step 2 is: Calculate the flow rate in mL/hour:. 2 milliunits/min ÷ 20 milliunits/mL × 60 min/hour = 6 mL/hour.

Final answer: 6.
