MSF Exam2 QUESTIONS AND CORRECT ANSWERS LATEST UPDATE 2023 c. ADH release is increased 1. As a compensatory response to hemorrhage, which of the following might occur? a. Inhibition of ADH release b. Inhibition of aldosterone release c. ADH release is increased d. Angiotensin I levels decrease c. Action potential firing rate to the medulla decreases 1. You’ve been binge-watching American Horror Story and have been in bed for a long time. You hear a knock at the door and you think it’s your pizza being delivered so you get up very quickly and feel a little light-headed. Which of the following occurred immediately upon standing? a. ADH is released to increase blood volume b. Cardiac output increases due to an increase in venous return c. Action potential firing rate to the medulla decreases d. Low blood pressure activates the renin-angiotensin aldosterone system d. Venous return would be increased due to venoconstriction 2. Which of the following are true regarding compensatory responses to hemorrhage? a. Increased venous compliance or capacitance causes an increase in preload b. Vasoconstriction causes an increase in stroke volume c. R-R intervals on an ECG would lengthen d. Venous return would be increased due to venoconstriction d. Baroreceptor reflex 3. Which of the following compensatory mechanisms have the most significant effect on correcting a decrease in arterial pressure caused by a healthy person standing up very quickly? a. Microcirculation adjustments b. Renin-angiotensin-aldosterone system c. CNS ischemic response d. Baroreceptor reflex c. A because decreases in end diastolic volume will decrease stroke volume 1. Which of the following letters represent an immediate response to hemorrhage and why? a. B because decreases in afterload will increase stroke volume b. B because increases in end diastolic volume will increase stroke volume c. A because decreases in end diastolic volume will decrease stroke volume d. A because decreases in venous capacitance will decrease preload b. Aldosterone is released 1. If blood volume decreases: a. ADH is inhibited b. Aldosterone is released c. Vasodilation will occur d. Angiotensin I conversion to Angiotensin II will be slowed a. Arterial pressure will eventually increase due to increases in blood volume 1. Angiotensin II will have which of the following compensatory effects? a. Arterial pressure will eventually increase due to increases in blood volume b. Cardiac output will be decreased due to decreases in stroke volume c. Antidiuretic hormone release will cause Na+ retention at the level of the kidney d. Decreased aldosterone release will cause water to be reabsorbed to the blood b. Cause release of atrial natriuretic peptide to increase removal of Na+ from the blood 1. Low-pressure baroreceptors do which of the following when they detect increased blood volume: a. Facilitate release of aldosterone to increase Na+ reabsorption b. Cause release of atrial natriuretic peptide to increase removal of Na+ from the blood c. Inhibit the release of antidiuretic hormone in order to decrease water reabsorption d. Decrease heart rate in order to decrease blood pressure d. Decreases hydrostatic pressure in the capillaries 1. Decreased arterial pressure (i.e. in response to blood volume losses) a. Increases hydrostatic pressure in the interstitial flui
