Following a cardiac catheterization and placement of a stent in the right coronary artery, the nurse administers prasugrel to the client. To monitor for adverse effects from the medication, which assessment is most important for the nurse to include in this client's plan of care?

Choice A reason: Measuring body temperature is a standard procedure but not directly related to monitoring for adverse effects of prasugrel, which primarily include bleeding complications. Choice B reason: Assessing skin turgor is generally used to evaluate hydration status and is not specific to prasugrel's adverse effects. Choice C reason: Checking for pedal edema can indicate heart failure or vascular problems but is not a direct indicator of prasugrel's adverse effects. Choice D reason: Observing the color of urine is important as prasugrel can cause significant and sometimes fatal bleeding. Dark or bloody urine may be an early indicator of such bleeding.
