A client with type II diabetes is scheduled to have a computed tomography (CT) scan with IV contrast of the brain to rule out a brain tumor. What health teaching would the nurse include?
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 ["A","J"]

Explanation

Intervention: Validate that informed consent has been given by the client.

Reason: Before any invasive procedure, it is crucial to ensure that the client has given informed consent. This means the client understands the procedure, its risks, benefits, and any potential complications. Validating informed consent is a legal and ethical requirement that ensures the client is making an informed decision about their care12.

Assessment: The trachea is shifted away from the midline of the neck.

Reason: A tracheal shift is a critical finding that warrants immediate action. It can indicate a tension pneumothorax, which is a life-threatening condition where air accumulates in the pleural space and causes the lung to collapse. This shift can compromise respiratory function and requires urgent intervention34.

Choice B: Pulse oximetry is 93% on 2 L of oxygen.

Reason: While a pulse oximetry reading of 93% on 2 liters of oxygen is slightly below the normal range (95-100%), it is not immediately life-threatening. However, it does indicate that the client may need further evaluation and monitoring to ensure adequate oxygenation.

Choice C: The client rates pain as 8/10 at the site of the procedure.

Reason: Pain management is important, but an 8/10 pain rating at the procedure site, while significant, does not require immediate action compared to a tracheal shift. Pain can be managed with appropriate analgesics as ordered by the physician.

Choice D: Request an order for pain medication.

Reason: Requesting an order for pain medication is a necessary intervention for managing the client’s pain, but it is not as urgent as addressing a tracheal shift. Pain management should be part of the overall care plan.

Choice E: Measure oxygen saturation before and after a 12-minute walk.

Reason: Measuring oxygen saturation before and after a 12-minute walk is a useful assessment to evaluate the client’s respiratory function and endurance. However, it is not an immediate priority compared to ensuring informed consent and addressing critical findings.

Choice F: Explain the procedure in detail to the client and the family.

Reason: Explaining the procedure in detail to the client and their family is essential for informed consent and reducing anxiety. It ensures that the client understands what to expect and can make an informed decision about their care.

Choice G: Assist the client to the bathroom.

Reason: Assisting the client to the bathroom is a routine nursing intervention that ensures the client’s comfort and dignity. However, it is not a priority compared to addressing critical findings and ensuring informed consent.

Choice H: Discuss all possible complications with the client.

Reason: Discussing all possible complications with the client is part of the informed consent process. It ensures that the client is aware of potential risks and can make an informed decision about their care.

Choice I: A small amount of drainage from the site is noted.

Reason: Noting a small amount of drainage from the site is an important assessment, but it is not as urgent as addressing a tracheal shift. The drainage should be monitored and documented, and any significant changes should be reported to the physician.

A. Increased serum albumin B. Decreased serum bilirubin C. Decreased serum ammonia D. Decreased serum alanine aminotransferase (ALT)

Correct Answer is C

Explanation

Choice A Reason: Increased Serum Albumin

Increased serum albumin is not a direct indicator of the therapeutic effect of lactulose in patients with chronic hepatitis. Albumin is a protein made by the liver, and its levels can be affected by liver function. However, lactulose primarily works by reducing ammonia levels in the blood, not by increasing albumin levels. Normal serum albumin levels range from 3.5 to 5.5 grams per deciliter (g/dL). While improved liver function might eventually lead to increased albumin levels, this is not the primary therapeutic effect of lactulose.

Choice B Reason: Decreased Serum Bilirubin

Decreased serum bilirubin is also not a direct indicator of lactulose’s therapeutic effect. Bilirubin is a byproduct of the normal breakdown of red blood cells and is processed by the liver. Elevated bilirubin levels can indicate liver dysfunction, but lactulose’s main role is to reduce ammonia levels, not bilirubin. Normal serum bilirubin levels are typically between 0.1 to 1.2 milligrams per deciliter (mg/dL). While improved liver function might reduce bilirubin levels, this is not the primary goal of lactulose therapy.

Choice C Reason: Decreased Serum Ammonia

Decreased serum ammonia is the correct indicator of the therapeutic effect of lactulose in patients with chronic hepatitis. Lactulose is used to treat hepatic encephalopathy, a condition caused by high levels of ammonia in the blood due to liver dysfunction. Lactulose works by converting ammonia into ammonium, which is then excreted from the body. Normal serum ammonia levels are less than 50 micromoles per liter (µmol/L) in adults56. A decrease in serum ammonia levels indicates that lactulose is effectively reducing the toxic levels of ammonia in the blood, thereby achieving its desired therapeutic effect.

Choice D Reason: Decreased Serum Alanine Aminotransferase (ALT)

Decreased serum alanine aminotransferase (ALT) is not a direct indicator of lactulose’s therapeutic effect. ALT is an enzyme found in the liver that helps convert proteins into energy for liver cells. Elevated ALT levels can indicate liver damage. Normal ALT levels range from 7 to 56 units per liter (U/L). While improved liver function might reduce ALT levels, lactulose’s primary role is to reduce ammonia levels, not directly affect ALT.
