McGahan, Kristina, RN, BSN. What Every Nurse Must Know: Telemetry Secrets. Published October 2025.

What Every Nurse Must Know: Telemetry Secrets was written to support nurses working with cardiac and telemetry patients by strengthening their ability to interpret cardiac monitoring and apply clinical judgment in real time. Drawing from nearly three decades of bedside nursing experience in cardiovascular and telemetry care, McGahan developed this resource to help nurses better recognize abnormalities on telemetry monitors and connect those findings with appropriate clinical assessments.

The book emphasizes practical critical thinking skills, guiding nurses to evaluate key clinical factors when telemetry changes occur, including electrolyte imbalances, lead placement accuracy, and vital sign changes. By connecting monitor interpretation with patient assessment, the text encourages nurses to move beyond simply observing the monitor to understanding the underlying physiological causes of rhythm changes.

In addition to her authorship, McGahan has extensive experience as a nurse preceptor and educator, contributing to hospital orientation and training programs where she has mentored new and experienced nurses in cardiac monitoring and telemetry interpretation.
