Stage 3 — Prioritize hypotheses. A pregnant client in the third trimester, whose blood pressure was normal at the first prenatal visit, has blood pressure 172/114 and 170/112 mm Hg measured 15 minutes apart. The client reports a persistent severe headache, seeing spots, and right-upper-quadrant pain. Platelets are 88,000/mm³ and AST is 126 units/L. Temperature is 36.9°C, and there is 1+ bilateral ankle edema. The fetal heart rate tracing shows minimal variability with recurrent late decelerations. Maternal symptoms and laboratory abnormalities persist. Complete the diagram by selecting the condition the client is most likely experiencing, 2 actions the nurse should take to address that condition, and 2 parameters the nurse should monitor to assess the client's progress.

Quick answer
Preeclampsia with severe features and HELLP syndrome; give the magnesium sulfate loading dose and IV labetalol; monitor blood pressure and platelet count.

Why this is correct
Two severe-range readings 15 minutes apart meet the threshold for urgent treatment, and cerebral symptoms plus right-upper-quadrant pain with platelets below 100,000/mm³ and a rising AST show end-organ injury. Magnesium prevents eclampsia, and labetalol lowers the risk of stroke. Blood pressure shows antihypertensive effect, and a falling or recovering platelet count shows whether HELLP is progressing.

Easy analogy or mental picture
Picture a pressure cooker leaking at the seams: the gauge is in the red (BP), steam is escaping at the brain (headache, spots) and the liver (RUQ pain, AST), and the gasket is wearing thin (platelets).

Memory hook
HELLP = Hemolysis, Elevated Liver enzymes, Low Platelets; treat with Mag for the brain and Labetalol for the BP.

NCLEX decision rule
Severe-range blood pressure plus cerebral or hepatic symptoms in pregnancy is an emergency: give seizure prophylaxis and urgent antihypertensive therapy before any further diagnostic workup.

Why the other choices are wrong
Cholecystitis explains RUQ pain but not severe hypertension or low platelets, and the client is afebrile, so WBC is not the key parameter. Gestational hypertension without severe features is excluded by severe-range pressures and organ injury. Migraine does not explain AST elevation. Steroids with a 48-hour delay are reasonable in stable early preterm cases, but not with HELLP and a nonreassuring tracing. A 24-hour urine or protein ratio no longer changes management once severe features are present. Platelet transfusion is not indicated at 88,000/mm³ without bleeding or surgery at a lower count. Glucose tracks acute fatty liver, not this condition.
