Final answer:
The appropriate action in this scenario would be to hold all medication until the pulse rate returns to 60 beats/minute.
Step-by-step explanation:
The licensed practical nurse is assessing the accuracy of the cardiac monitor and notes a heart rate of 34 beats/minute. A heart rate this low, along with the client's symptoms of feeling unwell and anxiety, indicates bradycardia. Bradycardia is a condition characterized by a slow heart rate, usually less than 60 beats/minute.
In consultation with the registered nurse, it is anticipated that the appropriate action would be to hold all medication until the pulse rate returns to 60 beats/minute, as option c suggests. Administering medications or cardiotonics to further slow the heart rate could be detrimental to the client's condition.
