Which of the following is a patient monitoring application?

• A. e-prescribing
• B. Computerized order entry
• C. Electronic charting
• D. Glucometers

Answer: (D)

Monitoring a patient’s physiological status by collecting measurements over time and feeding them into the clinical record is the concept being tested. A glucometer provides a measured blood glucose value and is used repeatedly to track diabetes control, often integrated with nursing workflows or an EHR so clinicians can observe glucose trends and respond to hypo- or hyperglycemia. In contrast, e-prescribing focuses on issuing and transmitting medications, computerized order entry handles placing orders for tests or treatments, and electronic charting covers recording patient information. Thus, glucometers are the patient monitoring tool among the options.
