In preparing a gravid client for a triple screen analysis, which action should the nurse take?

Choice A rationaleDrinking water is not necessary before a triple screen analysis. This test does not require a full bladder.Choice B rationaleThe left lateral tilt position is typically used to prevent supine hypotensive syndrome in pregnant women during ultrasounds, not for a blood draw.Choice C rationaleA triple screen analysis involves drawing blood from the mother to test for specific markers that indicate the risk of certain fetal abnormalities. Blood sampling is necessary for the analysis.Choice D rationaleApplying an external fetal monitor is unrelated to a triple screen analysis, which focuses on maternal blood markers rather than fetal heart rate monitoring.
