1. What is telemetry monitoring, and why is it important for patients with cardiac
concerns?
Telemetry monitoring is a process that continuously monitors a patient’s heart rate and rhythm
using electrodes placed on the chest. The heart rate and rhythm are then shown on a monitor
located at the nurse’s station. This is a crucial process because it enables the early detection of
irregular heart rhythms, facilitates prompt action in the event of a dangerous situation, and
assesses the effectiveness of medications used to treat the heart. (Dynamic Health, n.d.-a).
2. When placing ECG leads for telemetry, what steps should you take to make sure the
readings are accurate?
For accurate telemetry monitoring, the nurse must clean the patient’s skin with an alcohol swab
and allow it to dry before placing the electrodes. Additionally, if necessary, the nurse must shave
the hair on the patient’s skin to ensure that the electrodes stick properly. The electrodes should
not be placed on bony areas or areas of excessive breast tissue. All wires must be properly
connected, and loose or expired electrodes must be replaced (Dynamic Health, n.d.-a).
3. What does a 12-lead ECG show that telemetry does not, and when might a doctor order
one?
Telemetry monitoring only shows one or two views of the heart and continuously monitors the
heart rhythm. The 12-lead ECG is a more detailed view of the heart’s electrical activity from 12
different perspectives. It can indicate a heart attack, ST-segment changes, and the area of the heart
that is damaged. A doctor can order a 12-lead ECG if the patient has chest pain, new changes in
rhythm, or suspected myocardial infarction (Dynamic Health, n.d.-b; Dynamic Health, n.d.-c).
4. What should you do if a telemetry alarm goes off during your shift?
If the telemetry alarm sounds, the nurse should first check the patient. The nurse should check the
patient’s responsiveness, breathing, pulse, and vital signs. The nurse should also ask the patient
about symptoms such as chest pain and dizziness. After checking the patient, the nurse should
check the monitor and make sure the leads are correctly connected. If the patient is unstable, the
nurse should call the physician and initiate a rapid response if needed. It is always important for
the nurse to check the patient first before concluding that the problem is with the machine
(Dynamic Health, n.d.-a).
5. Why is it important to document rhythm changes and print ECG strips when you notice
something unusual?
Recording rhythm changes and printing ECG strips is important because it provides evidence of
what happened. It helps the nurse to monitor changes over time. It also helps the nurse to
communicate with other healthcare providers. It also protects the nurse in case of legal issues.
The nurse should record the time the rhythm change occurred, the symptoms of the patient, the
interventions done, and the people notified (Dynamic Health, n.d.-a; Dynamic Health, n.d.-b).
