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

Answer and Explanation

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: Inadequate retention of serum sodium is not typically associated with anemia in chronic renal failure.

Choice B reason: Inadequate production of erythropoietin is the correct answer because the kidneys produce erythropoietin, which stimulates the bone marrow to produce red blood cells. In chronic renal failure, the kidneys cannot produce enough erythropoietin, leading to anemia.

Choice C reason: While blood loss in the urine can occur, it is not the primary cause of anemia in chronic renal failure.

Choice D reason: Renal desensitization to Vitamin D aﬀects bone health and calcium levels but is not the primary cause of anemia in chronic renal failure.

A. Urine output B. Vital signs C. Name of the patient's dog D. Neurological status

Correct Answer is D

Explanation

Choice A reason: Urine output is important but not the priority after administration of fibrinolytic medication.

Choice B reason: Vital signs are routinely monitored but the priority is assessing for any signs of complications from the medication, such as bleeding or stroke.

Choice C reason: The name of the patient's dog is irrelevant to the patient's medical care and assessment.

Choice D reason: Neurological status is the priority to monitor for signs of intracranial hemorrhage, a potential complication of fibrinolytic therapy.
