Q29: what is the main reason you give a person (who has lost a lot of blood) intravenous. Uids? a. to increase their complexion, b. to increase their peripheral resistance, c. to increase their bp, d. to decrease their peripheral resistance, e. intravenous uids delivered are superior to blood in most ways.
