Right end- diastolic prossure C. Piessures in the vena cava d. Rulmonary vasaular resistance 13 a nurse observe s a cardiologist multiplying the heart rate by stroke volurme. What is the cardiologist maasuring? a. vascular resistance b. Pre load C. cardiac out put d. ojecton fraction nurse is evaluating the direct end eftect of the renin- angio tensin- aldosterone System. which principle should the nurse remember? a. angiotensin b. henin promote s the exuretion Of sodium and water in the renal tubules. C. Aidosterone increases renal retentión oF water only d. Angio tensin I promotes sadium and water reabsorphion Causes Systemic vasoconstriction by the kidneys tnereases in which of the following would cause the nurse to assess for decreased blood flow? (select all that apply) a. Blood viscosity b. Blood vessel d'ameter c. Blood pressure d. Blood vessel Length MEI

Answer 1

(12) Options .. Pulmonary vasculal resistance is the data resis- tance to blood flow to the pulmonaly alteries. Right ventricle pump blood to pulinionally arteries, perele vasulal resistance of these arteries effect right ventriculae afterlad ® Option c Cardial output is volume of blood pumped out in a given time. It can be get by multiplying stroke volume and numbee of rate). beats ( heart (19 Option A Scanned with CamScanner

. Low blood volume & low blood pressme Guses reinis release which buses angiotensin I release of us a potent vaso constori (tov, in constricts blood vessels and retain water and sodium . causes BP to vise to novinal ( A, C , D .. As viscosity increases blood become more thicke and more slowly. As blood pressure, the resistance to flow is also increases and blood flow decrease . As length of vessel increases, the area of resistance increases, blood flow dearlases.. CS Scanned with CamScanner
