A client presents to the healthcare setting and ordered verapamil (Calan) to treat his hypertension. Which assessment finding by the nurse would determine if the medication should be held?

A. A pulse oximetry of 92% indicates potential hypoxia but is not a direct contraindication for administering verapamil. B. A respiratory rate of 12 is not an immediate concern for verapamil; it is considered a normal rate in many cases. C. A recent history of myocardial infarction does not automatically contraindicate verapamil but should be assessed in the context of the client’s overall health and physician’s orders. D. A pulse of 78 is within a normal range; however, if the pulse were significantly low (e.g., below 60 bpm), verapamil would generally be held due to its potential to further decrease heart rate.
