A nurse is creating the plan of care for a client in active labor. Which of the following actions should the nurse include in the plan of care?
Keep four side rails up.
Insert an indwelling urinary catheter.
Check the cervix prior to administering medication.
Monitor the fetal heart rate (FHR) every hour.
The Correct Answer is C
Choice A rationale
Keeping four side rails up is a safety measure to prevent falls, but it is not specific to the care of a client in active labor. It is a general safety precaution used for clients who are at risk of falling or have impaired mobility.
Choice B rationale
Inserting an indwelling urinary catheter is not a routine action for a client in active labor. Catheterization is typically reserved for specific medical indications, such as urinary retention or the need for accurate urine output measurement in certain high-risk situations.
Choice C rationale
Checking the cervix prior to administering medication is crucial in active labor. This ensures that the medication is appropriate for the stage of labor and helps avoid complications such as administering pain relief too early or too late, which could affect labor progression and fetal well-being.
Choice D rationale
Monitoring the fetal heart rate (FHR) every hour is important, but it may not be frequent enough in active labor. Continuous or more frequent monitoring is often required to promptly detect any signs of fetal distress and take appropriate actions.

Correct Answer is C
Explanation
Choice A rationale
While a negative result in a Contraction Stress Test (CST) is desirable, this choice does not fully explain the significance of the result. A negative CST indicates that there are no late decelerations in the fetal heart rate in response to uterine contractions, suggesting that the fetus can handle the stress of labor.
Choice B rationale
This choice describes the criteria for a reactive Nonstress Test (NST), not a Contraction Stress Test (CST). In a CST, the focus is on the fetal heart rate response to contractions, not the number of contractions or variability.
Choice C rationale
A negative result in a CST indicates fetal well-being, meaning that the fetus can tolerate the stress of uterine contractions without showing signs of distress, such as late decelerations in the heart rate. This result suggests that the fetus is likely to handle labor well.
Choice D rationale
A positive result in a CST indicates that the fetus has late decelerations in response to contractions, which can be a sign of fetal distress. This result may suggest fetal growth restriction, lower Apgar scores, and the potential need for cesarean delivery. However, this choice does not fully capture the significance of a positive CST result.
Correct Answer is A
Explanation
Choice A rationale
This statement is incorrect. Vagus nerve stimulation actually decreases FHR variability. The vagus nerve, part of the parasympathetic nervous system, slows the heart rate and reduces variability.
Choice B rationale
This statement is correct. Baroreceptors are sensors located in blood vessels that help regulate blood pressure by detecting changes in the stretch of the vessel walls. They play a crucial role in maintaining stable blood pressure levels.
Choice C rationale
This statement is correct. The autonomic nervous system, which includes the sympathetic and parasympathetic nervous systems, controls the fetal heart rate. It regulates the balance between heart rate acceleration and deceleration.
Choice D rationale
This statement is correct. Chemoreceptors respond to changes in blood gas levels, such as oxygen and carbon dioxide. They help regulate respiratory and cardiovascular responses to maintain homeostasis.
