A nurse is caring for a client during a nonstress test (NST). At the end of a 30min period of observation, the nurse notes the following findings: The fetal heart rate baseline is 120/min with minimal variability and no accelerations. There are two decelerations of 15 /min in the fetal heart rate during a period of fetal movement, each lasting 20 seconds. Which of the following
interpretations of these findings should the nurse make?

The correct answer is B, C, and D.

Choice A: Increase the oxytocin infusion to 13 mu/min

Increasing the oxytocin infusion is not indicated in this scenario. Oxytocin is used to induce or augment labor, but if the fetal heart rate tracing is abnormal (Category 3), increasing oxytocin could exacerbate fetal distress. The priority is to stabilize the fetal condition before considering increasing oxytocin.

Choice B: Initiate a bolus of primary IV fluids

Initiating a bolus of primary IV fluids is appropriate. This action helps improve placental perfusion and maternal hydration, which can be beneficial in response to abnormal fetal heart rate tracings. Adequate hydration can enhance uteroplacental blood flow and improve fetal oxygenation.

Choice C: Place the client in a sidelying position

Placing the client in a sidelying position is recommended. This position can improve uteroplacental perfusion and fetal oxygenation, especially if there are signs of fetal distress. It helps to alleviate pressure on the inferior vena cava, enhancing blood flow to the placenta.

Choice D: Apply oxygen at 10 L/min via a venturi mask

While oxygen may be indicated for fetal distress, the correct method is usually a non-rebreather mask at 10 L/min, not a venturi mask. A venturi mask delivers more precise oxygen concentrations but not high-flow oxygen, which is needed in this scenario.

Choice E: Perform a sterile vaginal examination (SVE)

A vaginal exam assesses labor progression, cervical dilation, station, and fetal position. This is important for determining whether labor is progressing appropriately or whether further interventions are needed.

A. Position the client on her side: Late decelerations are often associated with uteroplacental insufficiency, which may be improved by changing the maternal position to improve blood flow to the placenta.
B. Elevate the client's legs: Elevating the client's legs would not directly address the cause of late decelerations.
C. Increase the infusion rate of the IV fluid: While ensuring adequate hydration is important, it is not the priority action when late decelerations are noted.
D. Administer oxygen via a face mask: Oxygen administration may be necessary, but it is not the priority action. Positioning the client on her side to improve blood flow is the priority.
