Chapter 1: Problem 140

The nurse understands that the diagnosis of oral cancer is confirmed with: A. Biopsy B. Gram Stain C. Scrape cytology D. Oral washings for cytology

Short Answer

Expert verified
Answer: Biopsy

Step by step solution

01

Eliminate incorrect options

First, we will eliminate the options that are not used for diagnosing oral cancer. Gram Stain (Option B) is utilized for bacterial identification, and Oral washings for cytology (Option D) are primarily used for detecting respiratory infections. These two options are not related to oral cancer diagnosis. Therefore, we can eliminate options B and D.
02

Analyze the remaining options

We are now left with two options - A. Biopsy and C. Scrape cytology. Both methods are used to analyze the sample of tissue or cells to determine if they are cancerous. However, there is a difference in specificity and accuracy between them.
03

Determine the most accurate method

Biopsy (Option A) provides a more definitive and accurate diagnosis, as it involves obtaining a sample of tissue for examination under the microscope. This allows for a thorough assessment of the tissue and can clearly indicate if it is cancerous or not. On the other hand, Scrape cytology (Option C) involves scraping a small number of cells from the suspicious area and examining them. While this method also helps in diagnosing oral cancer, it might not provide the same level of accuracy as a biopsy.
04

Choose the correct answer

Considering the accuracy and definitive result provided by the biopsy, the nurse understands that the diagnosis of oral cancer is confirmed with option A, Biopsy.
