takes
the focus away from
the nausea.
83
must be done at once and indicates that the patient’s well-being may be compromised by any delay
STAT
84
lack of oxygen. It can result from an inadequate supply of oxygen to the respiratory system, an inability of the blood to carry oxygen to the tissues, or an inability of the tissues to absorb the oxygen.This condition can usually be avoided by having the patient sit up gradually.
