Vital signs are: BP 110/70 mmHg, HR 95 bpm, temperature 98.6°F. The fetal heart rate is 140 bpm with good variability. What is the priority nursing assessment for this client?

Priority assessment is evaluating bleeding characteristics to determine severity and guide immediate interventions for suspected placenta previa. Sterile vaginal exam is contraindicated, while urine specimen and fundal height are less urgent.
Clinical Presentation Analysis
A 32-year-old client at 28 weeks gestation presents with sudden, painless, bright red vaginal bleeding. The vital signs are stable (BP 110/70 mmHg, HR 95 bpm), and the fetal heart rate is reassuring at 140 bpm with good variability. This classic presentation of painless bleeding in the third trimester is the hallmark of placenta previa, a condition where the placenta implants over or near the internal cervical os .
Rationale for the Priority Assessment
The correct answer is to assess the amount and characteristics of vaginal bleeding. In the context of a suspected placenta previa, the immediate nursing priority is to quantify blood loss and evaluate the ongoing risk to both the client and the fetus. The study by Asim et al. confirms that placenta previa is a major cause of maternal morbidity and mortality, primarily due to hemorrhage . Therefore, a precise baseline assessment of the bleeding—noting the volume, color, and presence of clots—is essential to guide further interventions such as intravenous fluid resuscitation, blood product preparation, and determining the urgency of delivery. This assessment directly informs the clinical team about the severity of the hemorrhage and the hemodynamic stability of the client.
Why Other Options Are Contraindicated or Not the Priority
- Sterile vaginal examination: This is strictly contraindicated in the setting of suspected placenta previa. A digital examination can disrupt the low-lying placenta over the cervical os, potentially causing a catastrophic, life-threatening hemorrhage for both the client and the fetus . The priority is to avoid any mechanical disruption of the placenta.
- Obtaining a clean-catch urine specimen: While a urinalysis is a part of routine prenatal care, it does not address the immediate, life-threatening complication of acute hemorrhage. The potential for an intrauterine infection, as explored in the context of placenta previa and bleeding by Jiang et al., is a secondary concern that is managed after the acute hemorrhagic risk is stabilized [4].
- Measuring fundal height and assessing fetal position: This assessment provides information about fetal growth and lie, which is important for delivery planning. However, in an acute bleeding episode, this is not the priority. The immediate threat is maternal exsanguination and fetal hypoxia from placental compromise, making the direct assessment of blood loss the critical first step.
Connecting Pathophysiology to Clinical Judgment
The underlying pathophysiology explains the clinical decision-making. In placenta previa, the placenta's location in the lower uterine segment is inherently unstable. As the third trimester progresses, the lower uterine segment begins to thin and efface in preparation for labor. This physiological change can shear the inelastic placenta away from the uterine wall, tearing maternal blood vessels and causing the characteristic painless bleeding . The amount of bleeding is directly correlated with the degree of placental separation and the size of the ruptured vessels. While rare, other vascular causes like ruptured cervical varices can also present with painless, massive bleeding, as documented by Thanasa et al., reinforcing the critical need to immediately characterize the source and volume of blood loss to determine the etiology and urgency of the situation . The priority is to first determine "how much and how fast" the client is bleeding to prevent hypovolemic shock and fetal distress.

A 32-year-old G2P1 client at 28 weeks presents with sudden, painless, bright red vaginal bleeding. Vital signs and fetal heart rate are currently stable. The primary concern is placenta previa until proven otherwise.
Priority Nursing Actions
Quantify Blood Loss: Immediately assess the amount of bleeding by weighing pads or chux (1 gram = 1 mL blood loss). Note the color (bright red suggests active bleeding) and presence of clots.
No Vaginal Examination: Strictly avoid digital cervical examination. This can disrupt a low-lying placenta and precipitate catastrophic hemorrhage. This contraindication must be clearly communicated to all team members and documented.
Initiate Continuous Monitoring: Place the client on continuous electronic fetal monitoring and tocodynamometry. Assess for uterine contractions, which may be present, and monitor fetal heart rate for signs of distress (tachycardia, bradycardia, late decelerations).
Maternal Stabilization: Establish large-bore intravenous (IV) access (at least 18-gauge) for fluid resuscitation. Type and crossmatch blood for potential transfusion. Monitor maternal vital signs every 5-15 minutes to detect early signs of hypovolemic shock (tachycardia, hypotension).
Prepare for Diagnostic Ultrasound: The diagnosis is confirmed by transabdominal ultrasound to locate the placenta. If transabdominal is inconclusive and placenta previa has not been ruled out, a transvaginal ultrasound may be performed by a qualified provider using strict aseptic technique, as it is safer than a digital exam.
Clinical Decision-Making Guidance
The management goal is to prolong the pregnancy to at least 36-37 weeks if maternal and fetal status remain stable. Immediate delivery, regardless of gestational age, is indicated for life-threatening maternal hemorrhage or non-reassuring fetal status. Administer antenatal corticosteroids (betamethasone) if delivery is anticipated within 7 days and gestational age is between 24 and 34 weeks. Prepare for a cesarean delivery, as this is the required mode of birth for placenta previa.
Documentation Essentials
Time of bleeding onset, estimated blood loss, and description of blood.
Maternal vital signs and fetal heart rate tracing interpretation.
Notification of the provider and the specific order to withhold vaginal examinations.
IV access site, gauge, and fluids administered.
Client's emotional status and support person presence.
Placenta Previa — A condition where the placenta implants in the lower uterine segment, over or near the internal cervical os, often presenting with painless, bright red vaginal bleeding in the third trimester.
Antepartum Hemorrhage — Bleeding from the genital tract during pregnancy after 24 weeks of gestation and before the birth of the baby, a leading cause of maternal and perinatal morbidity and mortality.
Painless Vaginal Bleeding — A classic hallmark symptom of placenta previa, distinguishing it from placental abruption which typically presents with painful bleeding and uterine hypertonicity.
Contraindication — A specific situation in which a procedure or treatment should not be used because it may be harmful; digital cervical examination is contraindicated in suspected placenta previa.
Hemodynamic Stability — The state of stable blood flow and perfusion, assessed through vital signs such as blood pressure and heart rate, which can initially be normal even with significant blood loss.
