The nurse is caring for a gravida 1 admitted in labor. Which finding would suggest the need for an internal fetal monitor? A. The cervix is dilated \(5 \mathrm{~cm}\). B. The fetal heart tones are difficult to assess using the external toco monitor. C. The fetus is at station 0 . D. Contractions are every 3 minutes.

Short Answer

Answer: The fetal heart tones are difficult to assess using the external toco monitor.

Step by step solution

01

Understand the options

Let's review the given options: A. The cervix is dilated \(5 \mathrm{~cm}\). B. The fetal heart tones are difficult to assess using the external toco monitor. C. The fetus is at station 0. D. Contractions are every 3 minutes. We will evaluate each option to determine which one would suggest the need for an internal fetal monitor the most.
02

Evaluate option A

A cervical dilation of \(5 \mathrm{~cm}\) represents the progression of labor, but it doesn't necessarily indicate the need for an internal fetal monitor. External fetal monitoring provides adequate heart rate data to assess the baby's well-being at this point in labor.
03

Evaluate option B

If the fetal heart tones are difficult to assess using an external toco monitor, that means an accurate assessment of the baby's heart rate and well-being is not possible. In this case, an internal fetal monitor becomes necessary to obtain clearer and more reliable data.
04

Evaluate option C

Station 0 describes the position of the fetus relative to the mother's pelvis and measures the progression of descent in labor. While it represents progress in the labor process, it does not indicate the need for an internal fetal monitor.
05

Evaluate option D

Contractions occurring every 3 minutes are a normal part of the labor process becoming more regular and intense, but they do not indicate the need for an internal fetal monitor. Fetal heart monitoring can be effectively performed using an external device in this situation.
06

Choose the correct option

As a result of the analysis, we can determine that option B, "The fetal heart tones are difficult to assess using the external toco monitor," suggests the need for an internal fetal monitor. This is because the accurate assessment of the baby's heart rate and well-being is crucial during labor, and an internal monitor provides clearer, more reliable data when external monitoring is not sufficient.
