A nurse is assessing a client who is at 31 weeks of gestation.Which of the following findings should the nurse identify as an indication of a potential prenatal complication?

Choice A rationaleTingling of fingers in pregnancy is linked to hormonal changes and fluid retention, which may cause mild carpal tunnel syndrome. This is a common and non-complication-related discomfort in pregnancy.Choice B rationaleAbsence of clonus indicates no hyperreflexia or neurological compromise. In pregnancy, clonus presence may signal severe preeclampsia, but absence signifies normal neurological function.Choice C rationaleLeg cramps result from changes in calcium and magnesium metabolism during pregnancy. These are common but are not associated with serious complications unless persistent and related to electrolyte imbalances.Choice D rationaleBlurred vision may result from severe preeclampsia or elevated blood pressure, signifying potential end-organ damage. It requires immediate medical evaluation to prevent progression to eclampsia.
