The nurse suspects that a patient is experiencing cardiogenic shock. Which parameter indicates that the nurse's suspicion is correct?
1. Cardiac output of 8.9 L/min
2. Pulmonary artery wedge pressure (PAWP) of 8 mm Hg
3. Central venous pressure (CVP) of 5 mm Hg
4. Cardiac index (CI) of 1.8 L/min/m2
4
Rationale 1: This cardiac output is elevated and is not consistent with cardiogenic shock.
Rationale 2: The PAWP will be elevated in cardiogenic shock.
Rationale 3: This is a normal central venous pressure reading.
Rationale 4: The cardiac index (CI) is a measure of cardiac output and tissue perfusion in relation to the patient's body surface area. This reading would be consistent with cardiogenic shock.
