Why would a nurse check a serum creatinine level?

Choice a reason: Cleansing the area with hot water and soap is not recommended for managing skin irritation around the stoma. Hot water can further irritate the skin and soap may strip away natural oils, exacerbating the irritation. The skin around the stoma is sensitive and requires gentle care with mild cleansers and lukewarm water to prevent further irritation and damage.
Choice b reason: Avoiding the use of any type of moisturizer or lotion on the skin is not appropriate for managing skin irritation around the stoma. While certain products might not be suitable, using a proper moisturizer can help to soothe and protect the irritated skin. It's essential to choose a skin-compatible product designed for use around stomas to maintain skin health and prevent further irritation.
Choice c reason: Applying a protective barrier cream or paste around the stoma is the most appropriate intervention for managing skin irritation. These products create a protective layer between the skin and the ostomy appliance, reducing friction and irritation. They help to maintain the integrity of the skin, promote healing, and prevent further complications. Barrier creams and pastes are specifically formulated for use around stomas and are effective in protecting sensitive skin.
Choice d reason: Using adhesive tape to tightly secure the ostomy bag is not recommended for managing skin irritation around the stoma. Tightly applied adhesive tape can cause additional pressure and irritation to the already sensitive skin. Instead, it is better to use an ostomy appliance that fits well and is designed to adhere gently to the skin without causing irritation or damage. Proper fitting and gentle adhesion are key to preventing skin issues around the stoma.

Choice a reason: Simvastatin, a statin medication used to control high cholesterol, does not typically interact with IV contrast dye. There is no need to withhold simvastatin before radiological studies involving contrast dye. The primary concern with simvastatin is monitoring for potential side effects, such as muscle pain and liver function, but these are not directly related to contrast dye use.
Choice b reason: Pantoprazole, a proton pump inhibitor used to reduce stomach acid, does not have known interactions with IV contrast dye. It can be safely continued before, during, and after radiological studies involving contrast. The main considerations with pantoprazole are related to its effect on stomach acid and potential side effects like headaches or gastrointestinal issues.
Choice c reason: Valsartan, an angiotensin II receptor blocker used to manage hypertension, does not interact with IV contrast dye. There is no need to withhold valsartan before undergoing radiological studies with contrast. Valsartan is primarily concerned with managing blood pressure and may have side effects such as dizziness or increased potassium levels, but these are not influenced by contrast dye.
Choice d reason: Metformin, an oral hypoglycemic agent used to manage type 2 diabetes, should be withheld prior to radiological studies with IV contrast dye. There is a risk of lactic acidosis, a rare but serious complication, when metformin is combined with contrast dye. To reduce this risk, metformin should be withheld for at least 48 hours before and after the procedure, and renal function should be monitored closely. This precaution helps ensure the safety of clients undergoing radiological studies with contrast dye.
