A nurse observes reddish-purple spots and areas of purple bruising on a newly admited patient. Which laboratory results support this assessment finding?

Choice A reason: Dabigatran does not specifically slow the ventricular response; medications like beta-blockers are typically used for rate control in atrial fibrillation.

Choice B reason: Dabigatran is an anticoagulant that reduces the risk of stroke and systemic embolism in patients with nonvalvular atrial fibrillation by preventing clot formation.

Choice C reason: Dabigatran does not convert atrial fibrillation to sinus rhythm; that would be the role of antiarrhythmic drugs or procedures like cardioversion.

Choice D reason: While dabigatran can prevent clots from forming, it is not used to dissolve existing clots; thrombolytic agents are used for that purpose.

Choice A reason: Systolic Blood Pressure is not a direct measure of preload; it indicates the pressure in the arteries during the contraction of the heart muscles.

Choice B reason: Mean Arterial Blood Pressure is an average blood pressure in an individual during a single cardiac cycle, but it does not specifically measure preload.

Choice C reason: Central Venous Pressure (CVP) is a direct measure of the blood volume returning to the heart and the ability of the heart to pump the blood into the arterial system, making it a key indicator of preload.

Choice D reason: Systemic Vascular Resistance refers to the resistance to blood flow offered by all of the systemic vasculature, excluding the pulmonary vasculature, and is not a measure of preload.
