- QUESTION 8 Which of the following measures is used to determine if a patient has enough pressure to move blood to the tissues (enough pressure for perfusion to occur)? O viscosity O hematocrit 0 albumin levels O 0 pulse pressure mean arterial pressureQUESTION 6 A systemic capillary has a hydraulic pressure of 35 mm Hg at the arteriole side and a hydraulic pressure of 25 mm Hg on the venule side. Within the capillary, the colloid osmotic pressure is constant at 18 mm Hg. As a result: Fluid will be forced out of the capillary on the arteriole side and all of it will be absorbed by the lymphatics on the venule side Fluid will be absorbed by the capillary on the arteriole side and lymph will be supplied by the lymphatics on the venule side The fluid will be forced out continually from the capillary on both the arteriole and venule side Fluid will be absorbed by the capillary on the arteriole side and forced out of the capillary on the venule side Fluid will be forced out of the capillary at the arteriole side and reabsorbed by the capillary on the venule sideQUESTION 6 Using the figure below and given that the resistance in vessels A and B are equal, which of the following statements is correct? P, A P2 P = 100 mmHg P2 = 10 mmHg %3D P1 B P2 P, = 500 mmHg P2 = 410 mmHg Blood flow rate is equal in vessels A and B Blood flow rate is greater in vessel B as compared to vessel A Blood flow only occurs in vessel B due to the high pressures Blood flow will occur from P2 to P1 in vessel A

- QUESTION 5 When researchers are looking for evidence of cross-current exchange in non-avian diapsids, what is one thing that they look for? unidirectional flow through the lungs the presence of ribs the presence of a diaphragm the presence of choanaeQUESTION 1 Which of the following scenarios would be considered INAPPROPRIATE uses of indwelling catheters? Select all that apply. O Patient requires prolonged immobilization, e.g. pelvic fracture O As a substitute for nursing care of the patient or resident with incontinence O As a means of obtaining urine for culture or other diagnostic tests when the patient can voluntarily void D A patient requests a catheter so they do not have to get out of bedIn the human body, blood vessels can dilate, or increase their radii, in response to various stimuli, so that the volume flow rate of the blood increases. Assume that the pressure at either end of a blood vessel, the length of the vessel, and the viscosity of the blood re- main the same, and determine the factor Ralated/Rpormal by which the radius of a vessel must change in order to double the volume flow rate of the 79. blood through the vessel.
