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

Explanation

Choice A Reason:

Activating the hospital’s emergency or rapid response system is the most appropriate first action in this scenario. The client is exhibiting signs of a potentially life-threatening condition, such as airway obstruction or severe swelling that could compromise breathing. Immediate intervention by a rapid response team can provide the necessary advanced airway management and other critical care measures to stabilize the patient. This action prioritizes the client’s airway, breathing, and circulation, which are the fundamental aspects of emergency care.

Choice B Reason:

Placing a heart monitor on the client and observing for dysrhythmias is important but not the immediate priority in this situation. While monitoring the heart is crucial, the client’s airway and breathing issues take precedence. Addressing the airway obstruction and ensuring adequate breathing should be the first step before focusing on cardiac monitoring.

Choice C Reason:

Asking the charge nurse to come see the client immediately is a reasonable action, but it may delay the necessary urgent intervention. The charge nurse may not have the advanced skills or equipment required to manage a severe airway obstruction. Activating the rapid response system ensures that a team of healthcare professionals with the appropriate expertise and equipment can respond quickly.

Choice D Reason:

Checking the client’s blood pressure and heart rate is a standard nursing assessment, but it is not the immediate priority in this emergency situation. The client’s difficulty breathing and stridor indicate a potential airway obstruction, which requires immediate attention. Ensuring the airway is clear and the client can breathe is more critical than checking vital signs at this moment.

Choice E Reason:

Providing a calm and assuring environment for the client is important for reducing anxiety and stress, but it does not address the immediate life-threatening issue. While maintaining a calm environment is beneficial, the nurse must first ensure that the client’s airway is secure and that they can breathe adequately. This can only be achieved by activating the rapid response system.

A. Nonfat milk B. Apple C. Chocolate

Correct Answer is C

Explanation

Choice A Reason:

Nonfat milk is generally considered safe for individuals with GERD. While full-fat dairy products can exacerbate GERD symptoms due to their high-fat content, nonfat milk does not have this effect. It is low in fat and unlikely to trigger acid reflux. Therefore, nonfat milk is not a food that needs to be avoided by someone with GERD.

Choice B Reason:

Apples are typically safe for individuals with GERD. In fact, non-citrus fruits like apples are often recommended as part of a GERD-friendly diet. They are low in acid and unlikely to cause reflux symptoms. Therefore, apples do not need to be avoided by someone with GERD.

Choice C Reason:

Chocolate is a common trigger for GERD symptoms. It contains caffeine and theobromine, both of which can relax the lower esophageal sphincter (LES), allowing stomach acid to escape into the esophagus and cause reflux. Additionally, chocolate is high in fat, which can further exacerbate GERD symptoms. Therefore, it is advisable for individuals with GERD to avoid chocolate to prevent worsening of their symptoms.
