A Patient Was Admitted 3 Days Ago with a Myocardial

A patient was admitted 3 days ago with a myocardial infarction (MI) and has developed pulmonary edema. How would the nurse explain this condition to the patient and family?

A) The pulmonary system has an excessive amount of fluid that has been building over the last several days, and now the heart is no longer able to keep up with the demands.
B) The cardiac muscle has been injured and is not able to efficiently pump the blood through the patient's system, resulting in an increased pressure in the pulmonary system.
C) The pulmonary system was injured first due to hypoxia, which caused the heart attack.
D) The cardiac muscle is working too hard to push fluids through the pulmonary system and there is fluid excess as a result.
