Blood Pressure Regulation- Reyes

If Pa increases above or below a set point, what response will take place?

CV reflexes will make adjustments in CO and TPR

CO will decrease to return Pa to set point value

TPR will drastically decrease to return Pa to set point value

Neither CO or TPR will change, and baroreceptors will influence a decrease in HR

Which of the following mechanisms have the highest maximum feedback gain at optimal pressure over an interval of many days

What two factors regulate the mean arterial pressure of the body

Barorecepotrs and Reninangiotensin-aldosterone

Cardic output and Total peripheral resistance

SA Node and AV Node

Nucleus Tractus Solitarius and Sinus Nerve


Sympathetic Inhibition	1 2 3 4 5
Reduction in contractility	1 2 3 4 5
Heart Rate	1 2 3 4 5
Cardiac Output	1 2 3 4 5
Blood Pressure	1 2 3 4 5

The CNS ischemic response is NOT activated by which of the following

Which of the following is a direct consequence of severe cerebral ischemia?

These fibers fire during ventricular systole and gradually increase their firing rate as the atria fill, reaching maximum firing frequency at the peak of the v wave of the atrial pressure. Thus monitor the rising atrial volume.

The main purpose of the atrial and pulmonary artery reflex is to what?

Which of the following pharmacological factors would be important for a medication to control fluid volume overload?

During hemmorrage, blood pressure drops. This is one possible stimulus for angiotensin.

True

False

You are shadowing a doctor in the ER when a patient with a intracerebral hemorrhage (ICH) has just arrived. The doctor starts to treat the patient but you and your tiny ass bladder leave to go to the bathroom. You return to the patient and the attending doctor 20 min later. You notice that the BP is raising closer to normal levels. You are too embarassed to ask the doctor what they did. What is the best guess at the medication that was administered
