Final answer:
Prior to a liver biopsy, it is important to be aware of the patient's blood clotting status and any allergies to latex. History of smoking and recent food intake are not directly related to the procedure.
Step-by-step explanation:
Prior to a liver biopsy, there are several important factors to be aware of. One of them is the blood clotting status of the patient. Since a liver biopsy involves taking a sample of liver tissue, it can cause bleeding. Therefore, it is important to ensure that the patient's blood is clotting normally to minimize the risk of excessive bleeding.
Additionally, it is also important to inquire about any allergies to latex that the patient may have. Latex gloves are often used during medical procedures, including liver biopsies, and an allergic reaction to latex can be potentially serious.
The other options mentioned, history of smoking and recent food intake, are not directly related to a liver biopsy and would not have a significant impact on the procedure.
