A patient is scheduled for a liver biopsy.
Which laboratory result would be of most concern to the nurse?
Serum ammonia level of 56 mcg N/dL
Hemoglobin of 11 g/dL
White blood cell count of 14.2 x 103/uL
Prothrombin time of 32 seconds
The Correct Answer is D
Choice A rationale
While an elevated serum ammonia level can indicate liver dysfunction, it is not typically a contraindication for liver biopsy. Ammonia is a byproduct of protein metabolism and is normally converted into urea by the liver, which is then excreted in the urine. Elevated levels can occur in liver disease, but they are not typically a direct concern in the context of a liver biopsy.
Choice B rationale
A hemoglobin level of 11 g/dL is slightly low, but it is not typically a contraindication for a liver biopsy. Hemoglobin is the protein in red blood cells that carries oxygen. While a low hemoglobin level can indicate anemia, it would not typically prevent a patient from undergoing a liver biopsy.
Choice C rationale
A white blood cell count of 14.2 x 103/uL is slightly elevated, indicating a possible infection or inflammation. However, this would not typically be a contraindication for a liver biopsy.
Choice D rationale
A prothrombin time of 32 seconds is significantly prolonged, indicating a potential problem with blood clotting. This would be a major concern for a nurse caring for a patient scheduled for a liver biopsy, as the procedure involves inserting a needle into the liver and could lead to bleeding. Patients with a prolonged prothrombin time are at an increased risk of bleeding complications.

Correct Answer is B
Explanation
Choice A rationale
While acetaminophen can be used to relieve discomfort, it should be used with caution in patients with liver disease like cirrhosis, as it can potentially cause further liver damage.
Choice B rationale
Patients with cirrhosis, especially those with ascites, are often advised to limit their sodium intake. High-sodium foods can contribute to fluid retention and worsen ascites. Therefore, avoiding high-sodium foods such as canned soups/vegetables, processed meats, and prepackaged frozen dinners is a key part of managing cirrhosis.
Choice C rationale
While maintaining adequate nutrition is important in cirrhosis, eating three large meals per day is not typically recommended. Instead, smaller, more frequent meals are often suggested.
Choice D rationale
While physical activity is generally beneficial, patients with cirrhosis and particularly those with complications such as ascites or encephalopathy may need to modify their activity levels based on their symptoms and overall health.
Correct Answer is B
Explanation
Choice A rationale
Asking why the patient thinks the copper helps with their arthritis might seem like a good way to understand their beliefs, but it could come off as challenging or dismissive.
Choice B rationale
Acknowledging that the patient feels better wearing the bracelet is a respectful response. It validates the patient’s experience without endorsing the effectiveness of copper bracelets, which lack scientific evidence for treating arthritis.
Choice C rationale
This response could be seen as dismissive of the patient’s beliefs and experiences. It’s important to respect patients’ choices in managing their symptoms, as long as those choices aren’t harmful.
Choice D rationale
While it’s true that there’s no scientific basis for believing objects have powers to make you feel better, saying this could come off as dismissive or disrespectful.
