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 A
Explanation
Choice A rationale
Gastroesophageal reflux disease (GERD) is a condition where stomach acid frequently flows back into the esophagus, causing discomfort. Certain lifestyle habits and diet can trigger or worsen GERD symptoms. Alcohol and caffeine are among the substances that can aggravate
GERD123. They can relax the lower esophageal sphincter, allowing stomach acid to flow back into the esophagus. Therefore, reducing or avoiding alcohol and caffeine can help manage GERD symptoms.
Choice B rationale
Aspirin is a nonsteroidal anti-inflammatory drug (NSAID) that can cause or worsen GERD symptoms. It can irritate the esophagus and stomach lining, leading to heartburn and other GERD symptoms. Therefore, it’s not advisable to take aspirin if you have GERD12.
Choice C rationale
While it’s important to avoid mercury-containing foods due to their potential health risks, there’s no specific link between these foods and GERD12. GERD is primarily triggered by foods that relax the lower esophageal sphincter, cause stomach distension, or irritate the esophagus. Mercury-containing foods do not fall into these categories.
Choice D rationale
Lying down after eating can indeed increase the onset of GERD123. When you lie down, it’s easier for stomach acid to backflow into the esophagus. This is why it’s recommended to wait at least 2-3 hours after eating before lying down.
Correct Answer is C
Explanation
Choice A rationale
Dysarthria, or difficulty articulating speech, is not a symptom of GERD. GERD primarily affects the digestive system, causing symptoms such as heartburn and regurgitation.
Choice B rationale
Dysesthesia, or abnormal sensation, is not a symptom of GERD. GERD does not typically cause sensory disturbances.
Choice C rationale
This is the correct answer. Dyspepsia, or indigestion, is a common symptom of GERD. It can manifest as discomfort or pain in the stomach or chest, a feeling of fullness, or problems with belching or gas.
Choice D rationale
Dyspnea, or shortness of breath, is not a typical symptom of GERD. While severe GERD can sometimes cause respiratory symptoms due to aspiration of stomach contents or irritation of the airways, it is not a common or primary symptom.
