Patients who have diabetes mellitus should have dilated eye exams at which of the following frequencies?

A. Administering IV medication: Administering intravenous (IV) medication is typically within the scope of practice for registered nurses (RNs) due to the complexity and need for careful monitoring.

B. Performing a heel stick on an infant: This procedure is often performed by medical assistants, especially in a pediatric setting, as it is part of routine blood collection practices.

C. Drawing blood for a glucose tolerance test: Medical assistants are usually trained to perform blood draws, including for glucose tolerance tests.

D. Performing venipuncture with a winged collection device: Medical assistants are generally trained to perform venipunctures, including using winged collection devices (butterfly needles).

A. 1: Checking the medication order against the label only once is insufficient for ensuring accuracy.
B. 2: While checking twice is better than once, the standard practice is to check three times for maximum accuracy.
C. 3: The "three checks" method involves checking the medication order against the label at three key points: when selecting the medication, when preparing it, and before administering it to the patient.
D. 4: Checking four times is not a standard practice and could be excessive; three checks are considered sufficient.
