A. While EHRs can be used for research purposes, this is not a primary benefit for individual patients. The focus of EHRs is on improving patient care, not necessarily facilitating research.
B. This is a significant benefit of EHRs, as it empowers patients to take an active role in their healthcare. They can review their medical history, medication lists, test results, and appointment schedules at their convenience. This access can also help patients to better understand their health conditions and make informed decisions about their treatment.
C. While EHRs can help to coordinate care between different providers, they may not necessarily include all healthcare received, especially if it comes from providers who do not use the same EHR system.
D. Access to patient information is typically restricted to authorized individuals, such as the patient themselves and their healthcare providers. While there may be exceptions, such as in cases of emergency or with the patient's consent, granting significant others access is not a standard feature of EHRs.

C. Only the client should administer the medication through the PCA device. Family members or other individuals should not be allowed to use the device.
D. The PCA device is designed to provide pain relief as needed. The client should use it whenever they experience pain, rather than waiting until the pain becomes severe.
