Vasoconstriction, sodium retention, and water reabsorption to increase circulating fluid volume and cardiac output are the primary functions of:
Stroke Volume
Renin-Angiotensin-Aldosterone-System (RAAS)
Brain and Atrial natriuretic peptides (BNP & ANP)
Erythropoietin
The Correct Answer is B
Choice A reason: Stroke Volume refers to the amount of blood pumped by the left ventricle of the heart in one contraction, not to the regulation of fluid volume and cardiac output.
Choice B reason: Renin-Angiotensin-Aldosterone-System (RAAS) is responsible for vasoconstriction, sodium retention, and water reabsorption, which helps to increase circulating fluid volume and cardiac output.
Choice C reason: Brain and Atrial natriuretic peptides (BNP & ANP) actually work to decrease blood volume and pressure, not increase them.
Choice D reason: Erythropoietin primarily stimulates red blood cell production and does not directly affect fluid volume or cardiac output.

Correct Answer is B
Explanation
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.
Correct Answer is C
Explanation
Choice A reason: Stopping seizure medication such as phenytoin without medical advice can lead to life-threatening seizures. It is not recommended to stop after a set period of being seizure-free without consulting a healthcare provider.
Choice B reason: Phenytoin should not be taken only during periods of stress; it is intended to be used consistently to maintain therapeutic levels in the body.
Choice C reason: Phenytoin may need to be continued indefinitely, depending on the individual's condition and the doctor's recommendation. It is often used as a long-term treatment for seizure control.
Choice D reason: This statement is misleading; while phenytoin helps control seizures, it does not cure the underlying condition causing them.
