A primigravida client at 32-weeks gestation presents to the clinic with a report of a pounding headache. The client demonstrates hyperreflexia. The nurse should recognize the client's symptoms may be caused by which condition?

A. Severe anxiety: Severe anxiety can cause headaches, palpitations, and increased blood pressure, but it does not cause hyperreflexia or the systemic vascular changes seen in pregnancy-related complications. While anxiety may contribute to subjective discomfort, the combination of a pounding headache and hyperreflexia in a pregnant client suggests a pathophysiological cause. B. Cerebral edema: Cerebral edema can develop in severe preeclampsia or eclampsia and may cause neurological symptoms such as headache, visual changes, and confusion. However, cerebral edema is a consequence of underlying vascular changes rather than the primary mechanism causing hyperreflexia and headache in this scenario. C. Intravascular coagulation: Disseminated intravascular coagulation (DIC) involves widespread clotting and bleeding and is a rare but severe complication in pregnancy. While DIC can occur with severe preeclampsia, it is not typically the immediate cause of a pounding headache and hyperreflexia in a 32-week gestation primigravida presenting to the clinic. D. Retinal arteriolar spasms: Retinal arteriolar spasms are part of the pathophysiology of preeclampsia and are associated with increased systemic vascular resistance. These spasms contribute to hypertension, visual disturbances, and pounding headaches, and are often accompanied by hyperreflexia due to heightened neuromuscular excitability. The client’s presentation aligns with preeclampsia-related vascular changes.
