A patient with gestational hypertension is exhibiting all of the signs below. What should the nurse report immediately?

Choice A rationale Urticaria, or hives, is a common cutaneous reaction characterized by the release of histamine from mast cells, often due to an allergic response. While uncomfortable, it is not typically a direct or immediate indicator of severe progression in gestational hypertension (preeclampsia). Severe preeclampsia symptoms relate to end-organ dysfunction, such as cerebral or hepatic involvement. Choice B rationale Diarrhea involves increased frequency and fluidity of stools, often related to gastrointestinal infection, dietary changes, or general motility disturbances. It is not a specific or critical sign of worsening gestational hypertension. Signs requiring immediate reporting usually involve central nervous system, liver, or renal compromise, reflecting widespread vasoconstriction and endothelial damage. Choice C rationale Blurred vision or scotomata (seeing spots) are critical signs of central nervous system irritability resulting from cerebral vasospasm and potential edema in the occipital cortex, often preceding eclampsia. This finding in a patient with gestational hypertension necessitates immediate reporting as it indicates severe end-organ damage and a heightened risk for seizures, demanding urgent intervention. Choice D rationale Backache is a nonspecific symptom common in pregnancy due to changes in posture, ligamentous stretching, and uterine growth. While severe, constant flank or back pain might suggest pyelonephritis or, rarely, hepatic capsule distention (a later, more severe sign), general backache is not an immediate, high-risk sign of progressive gestational hypertension compared to neurological symptoms.
