The nurse is reviewing pre-operative laboratory studies of an adult client on a medical-surgical unit. Which result should be reported to the physician immediately?

Choice A reason:
Administering oxygen using a non-rebreather mask is a subsequent step if initial measures do not improve fetal heart rate decelerations. It can help increase the amount of oxygen available to the fetus. Oxygen administration is a supportive measure that can be used if there are signs of fetal distress. In the scenario described, where the fetal heart rate slows after the start of a contraction with the lowest rate occurring after the peak, it suggests late decelerations, which are often associated with uteroplacental insufficiency. Administering oxygen can help increase the fetal oxygen reserve and is a common intervention during labor when there are concerns about fetal well-being.

Choice B reason:
Increasing the rate of maintenance IV infusion is typically considered when there is a concern for maternal hypotension or dehydration, which may not be the immediate cause of the observed fetal heart rate pattern. Increasing the rate of an IV infusion can help improve maternal hydration and blood pressure, which in turn can enhance placental perfusion. However, this intervention is more indirect and may not provide the immediate response needed to address fetal heart rate decelerations. It is typically considered after more direct interventions, such as repositioning the mother, have been attempted.

Choice C reason:
Elevating the client's legs can help improve venous return to the heart, potentially increasing maternal cardiac output and blood flow to the placenta. While this can be beneficial, it is not the primary intervention for late decelerations. Repositioning the mother to improve uteroplacental circulation is generally the first step.
Choice D reason:
Placing the client in the lateral position is often the first action taken when late decelerations are observed. This position helps improve uteroplacental blood flow and can quickly address potential issues related to fetal oxygenation. This position helps to relieve pressure on the inferior vena cava and aorta, which can be compressed by the gravid uterus, especially in the supine position. Relieving this pressure helps to improve uteroplacental circulation and can quickly address the cause of late decelerations, which is often related to compromised blood flow to the placenta.

Choice A reason:
Performing a 12-lead electrocardiogram and calling a rapid response team are important steps when a pulmonary embolism is suspected. However, these actions are not the immediate first-line interventions. The priority is to address the client's oxygenation needs to prevent further hypoxemia and potential cardiac arrest.

Choice B reason:
Elevating the head of the bed and applying 2 liters of nasal oxygen is the most appropriate initial intervention. This position helps improve the expansion of the lungs and oxygenation, while the supplemental oxygen can help alleviate hypoxemia, which is critical in the management of a pulmonary embolism.

Choice C reason:
While ensuring the client remains calm is beneficial, administering lorazepam is not the first-line treatment for a suspected pulmonary embolism. Lorazepam may be used for its anxiolytic effects, but it does not address the immediate life-threatening issues of oxygenation and potential hemodynamic instability.

Choice D reason:
Increasing the intravenous rate may be considered to maintain adequate hydration and venous return, but it is not the first intervention for a suspected pulmonary embolism. The priority is to stabilize the client's respiratory status and oxygenation.
