The nurse is assessing the client 24 hr later. How should the nurse interpret the findings? For each finding, click to specify whether the finding is unrelated to the diagnosis, an indication that the client's condition is improving, or an indication that the client's condition is worsening.

Choice A rationale

Asking about the fluid's color (clear, meconium-stained, bloody) provides information about fetal well-being and potential complications (like meconium aspiration), but it is a secondary assessment. While important, it does not supersede the need to immediately assess the most urgent physiological parameter of fetal status, which is the heart rate.

Choice B rationale

The rupture of membranes (water breaking) carries a risk of prolapsed umbilical cord, which can severely compromise fetal oxygenation by compressing the umbilical vessels. Determining the fetal heart rate (FHR) immediately is the priority action to identify signs of fetal distress, such as bradycardia (FHR <110 beats/min), indicating cord compression. The normal FHR range is 110-160 beats/min.

Choice C rationale

Monitoring cervical dilation is necessary to determine the stage and progress of labor. However, in the setting of ruptured membranes, assessing the immediate safety and stability of the fetus takes precedence over checking labor progress. A vaginal exam to check dilation is done after assessing FHR and ruling out immediate emergencies like cord prolapse.

Choice D rationale

Determining the vaginal pH with Nitrazine paper can confirm if the fluid is amniotic fluid (alkaline, pH 7.0-7.5) or urine/vaginal secretions (acidic). While this confirms the rupture of membranes, establishing the status of the fetus by assessing the FHR is the most critical and life-saving priority action to take first to prevent or quickly address fetal hypoxia.

Choice A rationale

Instructing the client to be NPO (nil per os), or nothing by mouth, is not typically required before an amniocentesis procedure. The client can usually eat and drink normally. Fasting is more commonly associated with procedures involving general anesthesia or those where there is a risk of aspiration, neither of which is routine for an amniocentesis. Clients may be asked to empty their bladder before the procedure to avoid puncturing it.

Choice B rationale

For an Rh-negative client undergoing an amniocentesis, there is a risk of fetomaternal hemorrhage during the procedure, which can lead to the mother's immune system producing Rh antibodies that attack the fetus's red blood cells in the current or future pregnancies. Therefore, administering Rh(D) immune globulin (RhoGAM) after the procedure is essential to prevent Rh sensitization. The standard dose is administered within 72 hours of the procedure.

Choice C rationale

Positioning the client in a left lateral position is typically used to promote optimal uteroplacental perfusion or during the second stage of labor. For an amniocentesis, the client is usually positioned in a supine position with a wedge placed under the right hip to slightly tilt the uterus and prevent vena cava compression, providing the provider with a clear anatomical view for ultrasound guidance.

Choice D rationale

The insertion site on the client's abdomen is cleaned with an antiseptic solution, such as povidone-iodine or chlorhexidine, to reduce the risk of introducing bacteria into the sterile field or uterus. Irrigating the site with sterile water is an inappropriate action for skin preparation as it is not a primary antiseptic and may interfere with the effectiveness of the chosen antiseptic solution.
