A client receives new prescriptions at 1000 that include discontinuing IV fluids and IV antibiotics. Which prescription should the practical nurse (PN) administer at 1300?

Regular insulin is the medication of choice for treating DKA. Its main action is to lower blood glucose levels by promoting the uptake of glucose into cells and inhibiting the production of glucose by the liver. Therefore, checking the fingerstick blood glucose level is an important indicator of the effectiveness of the insulin treatment.
A decrease in the blood glucose level indicates that the insulin is working to lower the high blood sugar associated with DKA. This measurement helps the PN assess the response to treatment and adjust the insulin dosage if necessary.
The other actions mentioned are also important assessments in the care of a client with DKA, but they do not specifically evaluate the effectiveness of the insulin dosage:
A. Smelling the client's breath for resolution of a fruity odor is important as it indicates a decrease in ketone production, which is a marker of improving DKA. However, it does not directly evaluate the effectiveness of the insulin dosage.
B. Determining the client's orientation to time and space is part of assessing their neurological status, which is crucial in managing DKA. However, it does not specifically assess the effectiveness of the insulin dosage.
C. Measuring the client's urinary output for an increased volume is important to monitor hydration status and renal function, but it does not directly evaluate the effectiveness of the insulin dosage.

The PN should instruct the UAP to observe and report any ear drainage after removing the device, as this may indicate an infection or irritation of the ear canal. The PN should also instruct the UAP to verify that the device is labeled with client's identification, as this can prevent mix-ups or misplacement of the device. The PN should also instruct the UAP to remove ear wax from the device's surface, as this can improve the sound quality and prevent damage to the device.

The other options are not correct because:

a. Keeping the battery door closed during storage is not a correct instruction, as it can drain the battery and shorten its life span. The PN should instruct the UAP to keep the battery door open during storage, as this can conserve the battery power and prevent corrosion.

c. Storing the device on the window sill to prevent loss is not a correct instruction, as it can expose the device to heat, moisture, or sunlight, which can damage its components or affect its function. The PN should instruct the UAP to store the device in a dry, cool, and safe place, such as a case or a drawer.
