Final answer:
The correct nursing note documentation is "Administered regular insulin 2 units SQ at 7:30 AM in the right lower abdomen to Mr. Preston, a 72-year-old patient." Insulin lowers blood glucose levels by helping transport glucose into cells.
Step-by-step explanation:
The most appropriate nursing note documentation for the care given to 72-year-old Mr. Preston is option (a): "Administered regular insulin 2 units SQ at 7:30 AM in the right lower abdomen to Mr. Preston, a 72-year-old patient." This option is the most detailed and provides all the required information in a clear and professional manner, which is essential for accurate medical records.
Clinical documentation must include specific information such as what medication was given, the dosage, the route of administration, the specific time it was administered, and to whom it was given. Additionally, it's important to note the exact location of the injection, as it facilitates better tracking of injection sites and rotation to prevent tissue damage.
Contrary to the statement labelled 'c', insulin injections are actually used to decrease blood glucose levels by facilitating the transport and storage of glucose into body cells, and are typically administrated prior to meals to manage the anticipated rise in blood glucose.
