What should a nurse monitor in a client receiving continuous cardiac monitoring?

In a client receiving continuous cardiac monitoring, it is essential for the nurse to focus on heart rate and PR interval for abnormalities. Continuous cardiac monitoring primarily aims to observe the electrical activity of the heart, which is reflected in the heart rate and the intervals between heartbeats, such as the PR interval.

The heart rate indicates how quickly the heart is beating, and deviations can alert the nurse to potential arrhythmias, which may require immediate intervention. Monitoring the PR interval is equally vital, as it assesses the time it takes for impulses to travel from the atria to the ventricles, helping to identify conditions like first-degree heart block or other conduction abnormalities.

The other aspects of monitoring, while important in a general sense, do not directly pertain to the primary objectives of continuous cardiac monitoring. Respiratory rate and blood pressure are critical parameters but are not the central focus when specifically looking at cardiac rhythms. Similarly, tracking activity level, oxygen saturation, temperature, and fluid intake are relevant for overall patient care but do not directly relate to the continuous observation of cardiac status indicated by heart rhythm abnormalities.
