Question

When assessing the hemodynamic information for a newly admitted patient in shock of unknown etiology, the nurse will anticipate administration of large volumes of crystalloids when the ____.

a. cardiac output is increased and the central venous pressure (CVP) is low.
b. pulmonary artery wedge pressure (PAWP) is increased, and the urine output is low.
c. heart rate is decreased, and the systemic vascular resistance is low.
d. cardiac output is decreased and the PAWP is high.

Answer 1

The nurse will anticipate administering large volumes of crystalloids when the patient's cardiac output is increased and central venous pressure (CVP) is low, indicating potential hypovolemic shock.

Step-by-step explanation:

When assessing the hemodynamic information for a newly admitted patient in shock of unknown etiology, the nurse will anticipate administration of large volumes of crystalloids when the cardiac output is increased and the central venous pressure (CVP) is low. This condition suggests that the patient may be experiencing hypovolemic shock, where there is a loss of blood volume leading to decreased preload and venous return, but the heart is still functioning and trying to maintain output. Treatments generally involve the administration of intravenous fluids to restore normal circulatory volume and various drugs to support hemodynamics.
