A nurse is caring for a newborn 4 hours after their birth.
Which of the following findings should the nurse report to the provider?

The nurse should first address the fetal heart rate followed by the client's vaginal discharge.

WBC count rationale: A WBC count of 22,000/mm³ is significantly elevated above the normal range of 5,000 to 10,000/mm³, suggesting maternal infection such as chorioamnionitis. While this is clinically important, it is not the immediate first priority in acute obstetric care. Maternal infection must be managed, but fetal well-being is prioritized first because hypoxia or distress can occur rapidly and requires immediate recognition and intervention before laboratory abnormalities are addressed.

Maternal Blood Type rationale: The maternal blood type of O negative is clinically relevant for Rh incompatibility and the need for Rho(D) immune globulin administration. However, this is not an acute priority in the setting of preterm labor with rupture of membranes. Blood type considerations are important for long-term management but do not supersede the need to assess fetal well-being or evaluate vaginal discharge for evidence of amniotic fluid leakage or bleeding.

Fetal heart rate rationale: Fetal heart rate monitoring is the highest priority because it provides real-time information about fetal oxygenation and well-being. The normal baseline range is 110 to 160 beats per minute, and this client’s rate of 148/min is within normal limits. However, continuous monitoring is essential due to preterm labor, rupture of membranes, and maternal fever, all of which increase the risk of fetal distress. Therefore, fetal heart rate assessment is addressed first to ensure immediate recognition of hypoxia or compromise.

Respiratory rate rationale: The maternal respiratory rate of 18/min is within the normal adult range of 12 to 20/min. This finding does not indicate acute compromise and does not require urgent intervention. While maternal respiratory status is always monitored, it is not prioritized above fetal assessment or evaluation of vaginal discharge in this scenario. Thus, respiratory rate is stable and requires only routine monitoring, not immediate follow-up in the prioritization of care.

Blood pressure rationale: The maternal blood pressure of 112/59 mm Hg is within acceptable limits for pregnancy, as mild decreases in systemic vascular resistance are physiologic. Hypotension would be concerning if systolic <90 mm Hg or diastolic <50 mm Hg, but this value does not indicate shock or preeclampsia. Therefore, blood pressure is not prioritized over fetal monitoring or vaginal discharge assessment in this case. It remains stable and requires routine monitoring only.

Vaginal discharge rationale: Vaginal discharge is the next priority after fetal heart rate because the client has clear fluid with nitrazine positive, confirming premature rupture of membranes, along with mucous discharge and bleeding. These findings raise concern for infection, preterm labor progression, and placental complications. Evaluating vaginal discharge helps determine the presence of amniotic fluid, blood, or purulent material, guiding urgent interventions. Therefore, it is addressed immediately after fetal heart rate monitoring to prevent maternal and fetal complications.

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.
