CCRN PRACTICE QUESTIONS
WITH ANSWERS
A 62-year-old man is admitted with chest pain. His electrocardiogram reveals ST
segment elevation and T wave inversion in leads V1 to V4. Aspirin has been given,
and morphine titration and nitroglycerin infusion are used to relieve his chest pain.
The patient suddenly develops a loud holosystolic murmur at the lower left sternal
border, chest pain, and hypotension 5 days after his myocardial infarction. A
pulmonary artery catheter is inserted. Which of the following parameters would be
noted in this patient?
A.
Increase in venous oxygen saturation (SvO2)
