A client with a history of seizures is scheduled for an electroencephalogram (EEG). Which instruction does the nurse give the client before the test?

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:

Administering levetiracetam intravenously is not the first intervention. While levetiracetam is an antiepileptic drug used to control seizures, it is not the first-line treatment for an ongoing seizure, especially one lasting as long as 15 minutes. The priority in this situation is to stop the seizure activity immediately to prevent further complications, such as neuronal damage or status epilepticus. Levetiracetam may be used later for maintenance therapy, but it is not the initial emergency intervention.

Choice B Reason:

Obtaining a STAT electroencephalogram (EEG) is important for diagnosing and understanding the type of seizure activity, but it is not the first intervention. The immediate priority is to stop the seizure. An EEG can be performed after the seizure has been controlled to assess brain activity and guide further treatment. Delaying the administration of an anticonvulsant to perform an EEG could result in prolonged seizure activity and increased risk of complications.

Choice C Reason:

Administering lorazepam intravenously is the most appropriate first intervention. Lorazepam is a benzodiazepine that acts quickly to stop seizure activity. It is the drug of choice for treating status epilepticus and prolonged seizures because of its rapid onset and effectiveness. Administering lorazepam helps to quickly terminate the seizure, reducing the risk of complications and stabilizing the patient for further evaluation and treatment.

Choice D Reason:

Obtaining a STAT 12-lead electrocardiogram (ECG) is not the first intervention. While an ECG can provide valuable information about the patient’s cardiac status, it does not address the immediate need to stop the seizure. The priority is to administer an anticonvulsant to terminate the seizure. Once the seizure is controlled, an ECG can be performed to assess any potential cardiac issues, especially if the patient has a history of cardiac problems or if the seizure was triggered by a cardiac event.
