Final answer:
The correct patient monitoring application among the provided options is d) glucometers. They are used by diabetic patients to monitor their blood sugar levels, unlike the other options, which involve electronic prescriptions, treatment instructions, or patient records.
Step-by-step explanation:
The question concerns identifying a patient monitoring application from a list of health informatics tools. Patient monitoring applications are those that allow for the continuous or periodic observation and recording of physiological parameters to assess a patient's health status or to manage chronic conditions. The correct answer is d. Glucometers. Glucometers are portable devices used by diabetic patients to measure their blood sugar levels regularly, thereby allowing both patients and healthcare providers to monitor and manage blood glucose levels.
Other options in the list, such as e-prescribing, computerized order entry, and electronic charting are not primarily patient monitoring applications. E-prescribing is a method for generating and sending prescriptions electronically; computerized order entry involves the entry of medical practitioner instructions for the treatment of patients; and electronic charting is a digital method of maintaining patient records. The answer is option d.
