NE is considered a: a) Positive inotropic b) Negative inotropic c) Positive chronotropic d) Negative chronotropic 17) What happens to cardiac output when the TPR increases? a) Increases b) Decreases c) Increases and then decreases d) Decreases and then goes back to normal 18) What happens to cardiac output when there is an increase in venous return? a) Increases b) Decreases c) No change d) Decreases and then increases 19) Reabsorption at the venules is promoted by: a) Blood pressure b) b. The hydrostatic pressure of interstitial fluid c) c. Blood colloid osmotic pressure d) d. Oncotic pressure of the interstitial fluid 20) A virus infected a cell. What can the body utilize to respond against it? a) Complement proteins (part of the inflammatory response) b) Inflammatory response (too general) c) Antibodies (virus already infected cell, antibodies are best for before virus infects cell) d) Cytotoxic T cells (will kill the cell) 21) Which type of capillaries does the blood-brain barrier have? a) Continuous b) Fenestrated c) Sinusoids d) Discontinuous 22) Which type of immunoglobulin is involved in an allergic reaction? a) IgM b) IgA c) IgD d) IgE 23) All of the following occurs during the plateau phase except a) Slow voltage-gated Ca2+ channels are open b) Fast voltage-gated Na+ channels are closed c) Slow voltage-gated Na+ channels are open d) Voltage-gated K+ channels are open 24) Cytotoxic T cells kill an infected cell with: a) Perforins b) Granzymes c) Both A and B d) Neither A or B 25) Which of the following does not occur during an inflammatory response? a) Increased blood flow to the injured site b) Vasoconstriction of the capillaries c) Accumulation of tissue fluid d) Neutrophils and monocytes phagocytosing pathogens 26) This cell releases cytokines to activate B-lymphocytes, increases the activity of macrophages, and in general regulates the overall immune response. a) Cytotoxic T lymphocyte b) Helper T lymphocyte c) Natural killer cell d) Basophil 27) One-year-old Matthew always seems to be sick. When his blood is tested, there are no antibodies. The physician concludes that the child is lacking a) The ability to develop an inflammatory response b) Helper t lymphocytes c) Cytotoxic T lymphocytes d) B lymphocytes 28) Which of the following is accurate: a) Total blood flow increases with a steeper pressure gradient (assuming resistance stays the same) b) Total blood flow decreases with increased resistance (assuming resistance stays the same) c) Total blood flow is significant in maintaining adequate perfusion of all tissues d) All of these are correct 29) Angiotensin II a) Does not increase blood volume b) Inhibit thirst centers in the hypothalamus c) Increases blood pressure d) All of the above 30) A mother breastfeeds her infant.
