A nurse is caring for a newborn. How many blood vessels should the nurse expect to observe in the newborn's umbilical cord?

Choice A rationale:

Increasing the rate of the maintenance IV infusion may be a rational action in some situations, but it is not the first priority when dealing with a fetal heart rate deceleration. The priority is to address the deceleration and potential fetal distress promptly.

Choice B rationale:

Administering oxygen using a nonrebreather mask might be beneficial for the client, but it is not the primary action to take when dealing with fetal heart rate deceleration. The priority is to address the deceleration and ensure fetal well-being.

Choice C rationale:

Elevating the client's legs is unlikely to have a significant impact on fetal heart rate deceleration. This action is more relevant in cases of maternal hypotension or when trying to improve venous return to the heart. It is not the first-line intervention for fetal heart rate decelerations.

Choice D rationale:

Placing the client in the lateral (side-lying) position is the correct action to take first. This position can help relieve pressure on the vena cava, improve blood flow, and increase oxygen supply to the fetus. By changing the client's position, the nurse can potentially resolve the fetal heart rate deceleration and improve fetal well-being.

The cervix is dilated 3 cm: This indicates the width of the cervical opening, which is 3 cm wide.

It is effaced 30%: This means the cervix has effaced or thinned out by 30%, indicating how much the cervix has shortened and thinned in preparation for labor.

The presenting part is 1 cm above the ischial spines (indicated by the negative number, -1): This measurement shows the position of the baby's head in relation to the ischial spines of the pelvis. In this case, the baby's head is 1 cm above the ischial spines.
Option A ("The cervix is dilated 3 cm, it is effaced 30%, and the presenting part is 1 cm below the ischial spines."): This option incorrectly interprets the baby's position as being 1 cm below the ischial spines, which is not the case. The negative sign (-1) in the documentation indicates that the presenting part is 1 cm above the ischial spines.

Option B ("The cervix is effaced 3 cm, it is dilated 30%, and the presenting part is 1 cm above the ischial spines."): This option switches the interpretation of dilation and effacement. In the original documentation, the dilation is given as 3 cm, while effacement is 30%. This option incorrectly states that effacement is 3 cm and dilation is 30%. Additionally, it correctly identifies the presenting part's position.

Option C ("The cervix is effaced 3 cm, it is dilated 30%, and the presenting part is 1 cm below the ischial spines."): This option correctly interprets effacement and dilation but incorrectly states that the presenting part is 1 cm below the ischial spines. The original documentation indicates that the presenting part is 1 cm above the ischial spines, as denoted by the negative sign (-1).
