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?
Pulse oximetry of 92%
Respiratory rate of 12
History of an myocardial infarction a week ago
Pulse of 78
The Correct Answer is D
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.

Correct Answer is ["675"]
Explanation
To calculate the dosage of vancomycin, we first convert the client's weight from pounds to kilograms, knowing that 1 kilogram is approximately 2.2 pounds. The client weighs 198 pounds, which is equivalent to about 90 kilograms (198 lb / 2.2). The prescribed dose is 15 mg/kg/day, so for a 90 kg individual, this would be 1350 mg/day (15 mg/kg * 90 kg). Since the dose is divided equally every 12 hours, the nurse would administer half of the daily dose every 12 hours, resulting in 675 mg per dose (1350 mg/day / 2). Therefore, the nurse should administer 675 mg of vancomycin with each dose.
Correct Answer is C
Explanation
A. Atenolol is a beta-blocker used for various cardiac conditions but is not typically the first-line treatment for acute ventricular dysrhythmias.
B. Lisinopril is an ACE inhibitor, which is not indicated for immediate management of ventricular dysrhythmias.
C. Procainamide is an antiarrhythmic medication specifically used to treat ventricular dysrhythmias and would be appropriate in this scenario.
D. Adenosine is typically used for rapid atrial dysrhythmias, not specifically for ventricular dysrhythmias, making procainamide the better choice.
