Your provider will obtain a signed consent from you prior to the completion of the CT scan.

You’ll need to let your doctor know if you have seafood allergies.

Do not take your scheduled dose of Metformin 500 mg PO.

The procedure will be done at the bedside.

Take your Metformin as usual before the test.

Answer and Explanation

The Correct Answer is B

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.

Correct Answer is D

Explanation

Choice A reason: No change to the heparin rate is not appropriate in this scenario. The normal range for PTT is generally between 25 to 35 seconds. However, for a client on heparin therapy, the target PTT is typically 1.5 to 2.5 times the normal range, which would be approximately 60 to 80 seconds. Since the client’s PTT is only 25 seconds, it indicates that the blood is clotting too quickly, and the heparin dose is insufficient.

Choice B reason: Decreasing the heparin rate would further reduce the anticoagulant effect, which is not advisable given the current PTT of 25 seconds. Lowering the heparin rate could increase the risk of thrombus formation and worsen the deep vein thrombosis (DVT) condition.

Choice C reason: Stopping heparin and starting warfarin is not an immediate solution. Warfarin takes several days to achieve its full anticoagulant effect, and during this transition period, the client would be at risk of clot formation. Heparin provides immediate anticoagulation, which is crucial in the acute management of DVT.

Choice D reason: Increasing the heparin rate is the correct action. The current PTT of 25 seconds is below the therapeutic range for a client on heparin therapy. Increasing the heparin rate will help achieve the desired anticoagulant effect, prolonging the PTT to the target range of 60 to 80 seconds.

A. Encourage dietary intake B. Encourage plenty of fat C. Serve dairy products D. Order a high-fiber diet

Correct Answer is D

Explanation

Order a high-fiber diet

Choice A Reason:

Encourage dietary intake

Encouraging dietary intake is generally important for maintaining nutritional status, but it is not specific to the preparation for a barium enema. The preparation for a barium enema typically involves dietary restrictions to ensure the colon is clear for the procedure. Therefore, this choice is not correct.

Choice B Reason:

Encourage plenty of fat

Encouraging plenty of fat is not appropriate for the preparation of a barium enema. High-fat foods can slow down the digestive process and may interfere with the clarity of the images obtained during the procedure. Therefore, this choice is not correct.

Choice C Reason:

Serve dairy products

Serving dairy products is not recommended before a barium enema. Dairy products can cause gas and bloating, which can interfere with the procedure. Additionally, some patients may be lactose intolerant, which can further complicate the preparation. Therefore, this choice is not correct.

Choice D Reason:

Order a high-fiber diet

Ordering a high-fiber diet is the correct choice. A high-fiber diet helps to clear the intestines by promoting bowel movements. This is important for ensuring that the colon is empty and clear for the barium enema, which allows for better imaging and more accurate results.
