A nurse is assisting in the care of a client who is in active labour. The nurse notes variable decelerations of the FHR. The nurse should identify which of the following is a cause of variable decelerations.

Choice A rationale:

Helping the client to the bathroom to empty her bladder is not the appropriate response in this situation. The client's sudden urge to push indicates that she is in the second stage of labor, which is the pushing phase. The cervix is already dilated at 7 cm, and the fetus is at 1+ station, indicating that delivery is imminent. Emptying the bladder at this point is not a priority and may delay necessary actions.

Choice B rationale:

Assisting the client into a comfortable position is also not the appropriate response. The client's urge to push suggests that she is in the active stage of labor, and her cervix is already 7 cm dilated. Encouraging a comfortable position might not be suitable since the focus should be on monitoring the progress of labor and preparing for delivery.

Choice C rationale:

Having the client pant during the next few contractions is not the correct response either. Panting is typically recommended during the transition phase of labor to prevent rapid pushing and potential damage to the perineum. However, in this scenario, the client is already fully dilated, and the fetus is at 1+ station, indicating that the second stage of labor has commenced. Panting is not necessary at this point.

Choice D rationale:

The appropriate nursing response is to assess the perineum for signs of crowning. The sudden urge to push indicates that the baby is descending through the birth canal and may be close to crowning, which is when the baby's head becomes visible at the vaginal opening. By assessing for crowning, the nurse can determine if delivery is imminent and notify the healthcare provider for further actions and preparation for the baby's birth.

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).
