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.
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 C
Explanation
Choice A Reason:
Weigh the client daily: While monitoring weight is important for clients with Addison’s disease, it is not the primary action to prevent an Addisonian crisis. Daily weight monitoring helps track fluid balance and detect any sudden changes that might indicate complications, but it does not directly address the hormonal imbalance that characterizes Addisonian crisis.
Choice B Reason:
Restrict food intake: Restricting food intake is not recommended for clients with Addison’s disease. Proper nutrition is crucial for maintaining energy levels and overall health. Clients with Addison’s disease need a balanced diet to manage their condition effectively. Restricting food intake could lead to malnutrition and exacerbate symptoms.
Choice C Reason:
Administer oral corticosteroids: This is the correct action. Addison’s disease is characterized by insufficient production of cortisol and aldosterone by the adrenal glands. Administering oral corticosteroids helps replace the deficient hormones and manage the symptoms of Addison’s disease. During an Addisonian crisis, immediate administration of corticosteroids is critical to prevent severe complications such as shock, coma, or even death.
Choice D Reason:
Provide a low carbohydrate diet: A low carbohydrate diet is not specifically recommended for clients with Addison’s disease. Instead, a balanced diet that includes adequate carbohydrates, proteins, and fats is essential. Carbohydrates are important for maintaining energy levels, especially since clients with Addison’s disease may experience fatigue and weakness. Restricting carbohydrates could lead to low blood sugar levels, which can be dangerous for these clients.
Correct Answer is C
Explanation
Choice A Reason:
The client who displays plantar flexion when the bottom of the foot is stroked is exhibiting a normal reflex response known as the plantar reflex. This response indicates that the corticospinal tract is functioning properly. In adults, the normal response is plantar flexion of the toes, which means the toes curl downward. This is not an immediate cause for concern and does not indicate a life-threatening condition.
Choice B Reason:
The client who consistently demonstrates decortication when stimulated is showing signs of severe brain injury. Decorticate posturing is characterized by the arms being flexed at the elbows and held tightly to the chest, with the legs extended and feet turned inward. This type of posturing indicates damage to the cerebral hemispheres, thalamus, or midbrain. While this is a serious condition, it is not necessarily the most immediate priority compared to a sudden change in the Glasgow Coma Scale.
Choice C Reason:
The client whose Glasgow Coma Scale (GCS) has changed from 15 to 12 is the nurse’s first priority. The GCS is a critical tool used to assess a patient’s level of consciousness, with scores ranging from 3 (deep coma) to 15 (fully awake and alert). A drop in GCS score indicates a significant decline in neurological function, which could be due to increased intracranial pressure, bleeding, or other acute changes in the brain. This requires immediate assessment and intervention to prevent further deterioration.
Choice D Reason:
The client whose deep tendon reflexes have become hyperactive is showing signs of hyperreflexia. Hyperactive reflexes can indicate an upper motor neuron lesion, which affects the descending corticospinal tract. While this is a concerning sign that warrants further investigation, it is not as immediately critical as a sudden change in the GCS score.
