Cold diuresis occurs when:
A) the initial peripheral vasoconstriction response in hypothermia is interpreted by the volume receptors as an increase in volume, causing the kidneys to produce more urine.
B) the sympathetic nervous system response in hypothermia increases blood flow to the kidneys, resulting in decreased sodium reabsorption and subsequent water excretion.
C) massive systemic vasoconstriction shunts cold body water to the renal system, where it is excreted from the body in an attempt to increase the core body temperature.
D) warmed IV fluids administered during severe hypothermia decrease the viscosity of the blood, resulting in an acute increase in output from the kidneys.
Answer: A) the initial peripheral vasoconstriction response in hypothermia is interpreted by the volume receptors as an increase in volume, causing the kidneys to produce more urine.
