A nurse is preparing to administer exenatide for a client who has type 2 diabetes mellitus. Which of the following routes of administration should nurse plan to use?

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.

Smoking is a known risk factor for the development of aspirin-induced ulcers. It can increase the risk of gastrointestinal bleeding and compromise the integrity of the gastric mucosa. Smoking can also impair the healing process and increase the risk of complications associated with ulcers.

While the other factors mentioned in the options may have their own health implications, smoking is specifically associated with an increased risk of aspirin-induced ulcers. Therefore, the nurse should identify the client's smoking habit as a risk factor for the development of an aspirin-induced ulcer.
