a. The patient has a history of iodine allergy
b. The patient has asthma and is being treated with albuterol
c. The patient's heart rate is higher than 65 bpm
d. The patient's heart rate is lower than 65 bpm

Answer 1

ß-blockers are likely to be used as part of a cardiac CT protocol when the patient's heart rate is higher than 65 bpm.

Step-by-step explanation:

ß-blockers are likely to be used as part of a cardiac CT protocol when the patient's heart rate is higher than 65 bpm. ß-blockers, also known as beta-blockers, are medications commonly used to treat cardiovascular diseases. They block the ß-receptors associated with vasoconstriction and cardioacceleration, helping to improve cardiac function by slowing down the heart rate and allowing blood vessels to dilate. By using ß-blockers in a cardiac CT protocol, the patient's heart rate can be controlled and stabilized, providing clear images of the heart during the procedure.
