A patient has hemorrhaged 1 liter of blood; he is diaphoretic (profuse perspiration),oliguric (decreased urinary output),and tachycardic.Physiologically,what is happening?

A) The patient has lost so much plasma protein (albumin) that fluid has shifted into his tissue spaces.
B) In response to the blood loss and declining blood pressure, the baroreceptor reflex has kicked in, causing a sympathetic discharge.
C) The shock-induced low blood pressure has caused a vagal discharge.
D) The shock-induced hypotension has inactivated all autonomic receptors.
