A nurse assesses clients on the medical-surgical unit. Which client is at greatest risk for development of obstructive sleep apnea?
 

Title: Choice A Reason:

Patients with seafood allergies may have a higher risk of allergic reactions to iodinated contrast media used in CT scans. However, this is not a definitive contraindication. The nurse should inform the patient to notify their healthcare provider about any known allergies, including seafood, as a precautionary measure. This allows the healthcare team to take necessary steps to prevent any adverse reactions, such as premedication with antihistamines or corticosteroids.

Title: Choice B Reason:

Metformin is a common medication used to manage type II diabetes. When a patient is scheduled for a CT scan with IV contrast, it is crucial to withhold Metformin before the procedure. This is because the combination of Metformin and iodinated contrast can increase the risk of contrast-induced nephropathy (CIN) and lactic acidosis, a rare but serious condition. The general recommendation is to stop Metformin at the time of or prior to the procedure and withhold it for 48 hours after the procedure, resuming only after renal function has been re-evaluated and found to be normal.

Title: Choice C Reason:

CT scans, especially those requiring IV contrast, are typically performed in a radiology suite equipped with the necessary technology and medical personnel. Performing such a procedure at the bedside is uncommon and not standard practice due to the need for specialized equipment and immediate access to emergency care in case of adverse reactions. Therefore, this statement is incorrect.

Title: Choice D Reason:

Taking Metformin as usual before the test is not recommended due to the risk of lactic acidosis when combined with iodinated contrast. As previously mentioned, Metformin should be withheld before and after the procedure until renal function is confirmed to be normal. This precaution helps to prevent any potential complications associated with the interaction between Metformin and the contrast agent.

Choice A Reason:

Documenting that the nasogastric tube is in the correct place is not appropriate in this scenario. The normal pH range for gastric contents is typically between 1.5 and 3.5. A pH of 7.35 is much higher than this range, indicating that the tube may not be in the stomach. Therefore, documenting the tube as correctly placed could lead to potential complications, such as improper feeding or medication administration.

Choice B Reason:

Notifying the health care provider is the correct action. A pH of 7.35 suggests that the nasogastric tube may be misplaced, possibly in the respiratory tract or another non-gastric location. Immediate notification of the health care provider is crucial to prevent any adverse outcomes and to take corrective measures, such as confirming placement with an X-ray or re-inserting the tube.

Choice C Reason:

Checking for placement by auscultating for air injected into the tube is not a reliable method for verifying nasogastric tube placement. While this method was traditionally used, it has been found to be inaccurate and is no longer recommended. The sound of air entering the stomach can be misleading and does not confirm correct placement.

Choice D Reason:

Retesting the pH using another strip is not the best immediate action. While it is important to ensure the accuracy of the pH reading, a pH of 7.35 is significantly outside the normal gastric range, and retesting is unlikely to yield a different result. The priority should be to notify the health care provider to address the potential misplacement of the tube.
