B.
BP 86/40 mm Hg, heart rate 92 beats/min
C.
BP 124/66 mm Hg, heart rate 124 beats/min
D.
BP 112/60 mm Hg, heart rate 92 beats/min - Answer A!
With a loss of 750 to 1500 mL of blood, an increase in heart rate greater than 100
beats/min and a narrowing of the pulse pressure is expected. These changes are due to
sympathetic nervous system innervation. Option a shows a narrow pulse pressure and
tachycardia.
Which is the most critical concern during the acute phase of care for a patient with an
intestinal obstruction?
A.
