A pregnant woman comes in for her weekly fetal heart monitoring.

She is 35 weeks’ gestation.

After 20 minutes on the monitor, the fetal heart rate tracing shows 3 accelerations measuring 15 beats by 15 seconds.

How should the nurse report this finding to the provider?

Rationale for Choice A:

Administering oxygen via a mask or nasal cannula is the most appropriate nursing intervention in this situation. Here's a detailed explanation:

1. Addresses Hypoxia: The client's symptoms of lightheadedness, dizziness, and tingling fingers strongly suggest hyperventilation, which can lead to hypoxemia (low blood oxygen levels). Administering oxygen directly increases the concentration of oxygen in the client's bloodstream, rapidly addressing the hypoxia and its associated symptoms.
2. Promotes Calmness: Oxygen therapy can also have a calming effect, which can help to slow the client's breathing rate and further improve oxygenation. This is crucial during the transition phase of labor, as anxiety and stress can exacerbate hyperventilation.
3. Supports Fetal Oxygenation: Ensuring adequate maternal oxygenation is essential for fetal well-being. By providing oxygen to the mother, the nurse is also indirectly supporting the oxygen supply to the fetus.

Rationale for Choice B:

Telling the client to breathe at a normal rate is not an effective intervention for hyperventilation. It's often challenging for a client experiencing hyperventilation to control their breathing rate on command. This approach can also increase anxiety, potentially worsening the hyperventilation.

Rationale for Choice C:

While notifying the physician is important to keep them informed of the client's status, it's not the immediate priority in this situation. The nurse can independently initiate oxygen therapy to address the client's hypoxia and improve her condition. The physician can then be consulted for further guidance or interventions if needed.

Rationale for Choice D:

Instructing the client to breathe into her cupped hands is a technique that can sometimes help to slow breathing and increase carbon dioxide levels. However, it's not as effective as administering oxygen in addressing the underlying hypoxia and may not provide sufficient relief for the client's symptoms.

Choice A rationale:

A positive contraction stress test (CST) indicates that the fetal heart rate decelerates late in response to uterine contractions, suggesting potential uteroplacental insufficiency. However, the scenario does not describe a CST being performed, as it does not mention any assessment of uterine contractions or their relationship to fetal heart rate changes.

Choice C rationale:

A negative contraction stress test (CST) would demonstrate no late decelerations in response to contractions, suggesting adequate placental function. However, as mentioned earlier, a CST is not the test being performed in this scenario.

Choice D rationale:

A non-reactive nonstress test (NST) means that there were not enough fetal heart rate accelerations (at least 2, each lasting at least 15 seconds and peaking at least 15 beats above baseline) within a 20-minute period. This finding sometimes warrants further evaluation of fetal well-being. However, the scenario clearly states that 3 accelerations meeting the criteria for reactivity were observed.

Choice B rationale:

A reactive nonstress test (NST) is considered reassuring and indicates that the fetal heart rate is responding appropriately to fetal movement, suggesting that the fetus is likely healthy and well-oxygenated. The presence of 3 accelerations meeting the criteria for reactivity within a 20-minute period is the hallmark of a reactive NST.
