Final answer:
The nurse should monitor for a low heart rate in a client with bradydysrhythmia.
Step-by-step explanation:
The nurse should monitor for low heart rate in a client with bradydysrhythmia. Bradydysrhythmia refers to a slower than normal heart rate, which can hinder the heart's ability to pump enough blood to meet the body's demands. This condition can result in symptoms such as fatigue, dizziness, and fainting.
