A nurse is reviewing the laboratory results of a client who has been taking warfarin for 3 months. Which of the following laboratory results Indicates that the medication has been effective?

When caring for a client receiving a continuous infusion of total parenteral nutrition (TPN), the nurse should implement the intervention of checking the client's blood glucose level regularly. TPN is a highly concentrated intravenous nutrition solution containing glucose, amino acids, lipids, vitamins, and minerals, and it is used to provide complete nutrition when the client cannot take oral nutrition.

Monitoring blood glucose levels regularly is essential because TPN is rich in glucose, which can significantly affect the client's blood sugar levels. Hyperglycemia (high blood sugar) is a potential complication of TPN infusion. Regular blood glucose monitoring allows the nurse to detect and address any changes in blood sugar levels promptly and to adjust the TPN infusion rate or administer insulin, if necessary, to maintain the client's blood sugar within the target range.

Let's go through the other options:

A. Change the TPN infusion tubing once every 3 days: While changing the TPN infusion tubing regularly is a good practice to maintain asepsis and prevent infection, it is not the priority intervention in this situation. Regularly checking the client's blood glucose level is more crucial to monitor the effects of TPN on blood sugar levels.

C. Insert the peripheral IV catheter for administration: Total parenteral nutrition is a hypertonic solution that can cause irritation and damage to peripheral veins. It is usually administered through a central venous catheter (CVC) placed in a large vein, such as the subclavian or jugular vein. Inserting a peripheral IV catheter for TPN administration is not recommended due to the risk of vein damage and thrombosis.

D. Monitor the client's weight every 3 days: Monitoring the client's weight is an important part of assessing their nutritional status and fluid balance. However, the priority intervention for a client receiving TPN is checking their blood glucose level regularly, as hyperglycemia is a common and significant concern in TPN administration.

When providing teaching to a client with chronic rheumatoid arthritis who is starting a new prescription for hydroxychloroquine, the nurse should instruct the client to obtain routine eye examinations. Hydroxychloroquine is an antimalarial and immunosuppressive medication commonly used to treat rheumatoid arthritis and other autoimmune conditions.

One of the potential side effects of hydroxychloroquine is ocular toxicity, particularly affecting the retina. Retinal toxicity can lead to vision changes or, in severe cases, irreversible damage to the eyes. Therefore, regular eye examinations are necessary to monitor for any signs of retinal toxicity and detect any visual changes early to prevent further complications.

The American Academy of Ophthalmology recommends that patients taking hydroxychloroquine undergo a baseline eye examination before starting the medication and annual eye examinations thereafter, especially after five years of continuous use.

Let's go through the other options:

B. Chest x-ray: A chest x-ray is not routinely required for monitoring clients taking hydroxychloroquine for rheumatoid arthritis. Hydroxychloroquine is not known to cause significant respiratory or pulmonary side effects.

C. Pancreatic enzyme levels: Monitoring pancreatic enzyme levels is not specifically related to hydroxychloroquine therapy. Pancreatic enzyme level testing is typically used to assess the function of the pancreas in conditions like pancreatitis or pancreatic insufficiency.

D. Urinalysis screening: While regular monitoring of kidney function is important for clients on long-term medication therapy, routine urinalysis screening is not specifically related to hydroxychloroquine use in clients with rheumatoid arthritis. Regular eye examinations are of higher priority due to the potential ocular toxicity associated with this medication.
