The nurse is taking care of a client diagnosed with advanced liver disease with hepatic encephalopathy. Lactulose (Cephulac) is administered to the patient to reduce which of the following?

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:

Weight gain is not typically associated with tuberculosis (TB). In fact, weight loss is a common symptom of TB due to the chronic nature of the infection and the body’s increased metabolic demands to fight the disease. Patients with TB often experience a loss of appetite and significant weight loss as the disease progresses.

Choice B Reason:

Low-grade fever is a common symptom of TB. The body’s immune response to the infection often results in a persistent low-grade fever, which can be one of the early signs of the disease. This fever is usually accompanied by other systemic symptoms such as night sweats and fatigue.

Choice C Reason:

Dyspnea, or difficulty breathing, can occur in patients with TB, especially if the infection has caused significant lung damage or if there is a large amount of fluid in the pleural space (pleural effusion). Dyspnea is a concerning symptom that indicates the need for further evaluation and treatment.

Choice D Reason:

Contusion, or bruising, is not a symptom associated with TB. TB primarily affects the lungs and can cause systemic symptoms, but it does not typically cause bruising. Contusions are more commonly associated with trauma or conditions that affect blood clotting.

Choice E Reason:

Lethargy, or a general sense of fatigue and weakness, is a common symptom of TB. The chronic nature of the infection and the body’s ongoing immune response can lead to significant fatigue. Patients with TB often feel tired and may have difficulty performing daily activities.

Choice F Reason:

Night sweats are a hallmark symptom of TB. Patients often experience drenching night sweats that can be quite severe. This symptom, along with fever and weight loss, is part of the classic triad of TB symptoms and is an important indicator for healthcare providers to consider TB in the differential diagnosis.
