The risk of hypoxia during circulatory shock is high. What efforts does the body make to combat this risk?
a. All listed options occur during circulatory shock to combat negative outcomes.
b. Epinephrine increases heart rate to attempt to maintain cardiac output.
c. Aldosterone and antidiuretic hormone are released to aid water retention, increase blood volume and pressure.
d. Blood vessels of the lungs and heart dilate to enhance perfusion.
