A patient diagnosed with a myocardial infarction has developed pulmonary edema. The family asks the nurse about the cause of this disorder. With which of the following should the nurse respond?

A) 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.
B) The pulmonary system was injured first due to hypoxia, which caused the heart attack.
