Understanding the Priority Concern
This client has a pre-pregnancy BMI of
32 kg/m², which falls into the obesity category. Obesity is a well-established risk factor for hypertensive disorders during pregnancy. At 36 weeks gestation, the priority assessment finding is a blood pressure of
150/95 mmHg. This reading indicates stage 2 hypertension in pregnancy and requires immediate attention because it is a cardinal sign of
preeclampsia, a condition that can rapidly progress to eclampsia and lead to severe maternal and fetal complications.
Why This is the Priority
The NCLEX-RN prioritization framework (often using Maslow's hierarchy, the ABCs, or the nursing process) directs the nurse to address life-threatening physiological risks first. Hypertension in pregnancy poses an immediate threat to maternal cerebral, hepatic, and renal function, as well as uteroplacental perfusion. The meta-analysis by Yi et al. (2026) provides evidence that maternal conditions during pregnancy are associated with an elevated risk of developing
preeclampsia [2]. Furthermore, research by Alaribe and Sapre (2026) underscores that
preeclampsia and
eclampsia remain leading causes of maternal mortality, particularly in high-risk populations
[3]. A blood pressure of
150/95 mmHg is a diagnostic criterion for preeclampsia with severe features, making it the most critical finding to report and act upon immediately.
Analysis of Other Options
The other assessment findings, while requiring follow-up, do not represent an immediate threat to maternal or fetal life in the same way that severe hypertension does.
- Option 2: Fundal height measuring 26 cm. At 36 weeks, the fundal height in centimeters should approximately equal the weeks of gestation (within 2-3 cm). A measurement of 26 cm is significantly less than expected and could indicate intrauterine growth restriction (IUGR) or oligohydramnios. While concerning, this finding does not pose the same immediate risk of maternal seizure, stroke, or abruptio placentae as severe hypertension.
- Option 3: Fetal heart rate of 145 beats per minute. This is a normal finding. The normal range for a fetal heart rate is 110-160 bpm. This value does not represent a concern.
- Option 4: Weight gain of 18 pounds since conception. For a client with a pre-pregnancy BMI in the obese category (≥30 kg/m²), the Institute of Medicine (IOM) recommends a total gestational weight gain of 11-20 pounds. A gain of 18 pounds falls within this guideline. While research by Yang et al. (2026) explores optimizing gestational weight gain ranges to reduce adverse outcomes, the study focuses on establishing population-specific ranges and notes that deviations from IOM recommendations are associated with adverse outcomes . A weight gain of 18 pounds is within the current standard recommendation and is not the priority concern compared to a critically elevated blood pressure.
Clinical Application of the Evidence
The pathophysiology linking the client's elevated BMI and hypertension is a state of chronic inflammation and endothelial dysfunction, which predisposes the client to placental hypoperfusion and the release of anti-angiogenic factors, driving the clinical syndrome of preeclampsia. The study by Brubaker et al. (2026) highlights the long-term cardiovascular significance of hypertensive disorders in pregnancy, noting that isolated diastolic or combined systolic-diastolic hypertension in the postpartum years can be a precursor to chronic cardiovascular disease . This underscores the importance of recognizing and intervening on a blood pressure of
150/95 mmHg not just for immediate pregnancy management, but as a critical event with implications for the client's future health. The nurse must prioritize notifying the healthcare provider, initiating seizure precautions, and preparing for potential administration of antihypertensive medication and magnesium sulfate for seizure prophylaxis.
