Final answer:
The acceptable intraoperative BP and HR range for patients with CAD, based on general guidelines, would be option a) 90-140 mmHg systolic and 60-90 bpm. This range ensures that systolic and diastolic pressures are neither too high to increase the risk of stroke or heart attack nor too low to cause fainting or poor circulation.
Step-by-step explanation:
The acceptable intraoperative blood pressure (BP) and heart rate (HR) range for patients with coronary artery disease (CAD) is best determined based on general guidelines for BP and HR along with the specifics of the patient's condition. Normal blood pressure is generally considered less than 120/80 mm Hg, while hypertension is categorized as 130/80 mm Hg or higher. The diastolic pressure should ideally be lower than 80 mm Hg but not less than 60 mm Hg. On the other hand, a normal resting heart rate (HR) for adults is between 60-100 bpm.
Considering these guidelines, option a) 90-140 mmHg systolic and 60-90 bpm is the choice that falls within the acceptable range for both BP and HR for patients with CAD. It is important to manage BP carefully, as chronically high systolic pressure significantly increases the risk of stroke and heart attack. Conversely, too low systolic pressure can result in fainting. The diastolic pressure is important for indicating fluid balance and proper dilation of blood vessels.
