Identifying Hypoperfusion in Post-CABG Patients

A patient who has undergone a coronary artery bypass graft (CABG) is being monitored in the intensive care unit (ICU). The nurse knows that one of the major concerns for patients post-CABG is the risk of complications related to impaired myocardial perfusion. If not promptly recognized and treated, this can lead to serious outcomes such as myocardial infarction or even cardiac arrest.

As the nurse, you must be vigilant in identifying signs of reduced perfusion. The patient is presenting with mottled skin, decreased urine output, and altered mental status. In this situation, it is critical to consider the most appropriate interventions to prevent complications related to impaired perfusion.
