Question

Which sample technique is done only when all other techniques cannot be completed?

1) Imprint
2) Fine-needle aspirate
3) Swabbing
4) Scraping

Answer 1

Swabbing is the sample technique used when other methods like imprints, fine-needle aspirates, or scrapings are not viable, employing a sterile swab soaked in sterile water to collect the sample aseptically.

Step-by-step explanation:

The sample technique that is typically used as a last resort when other techniques cannot be completed is swabbing. In situations where samples like imprints, fine-needle aspirates, or scrapings cannot be obtained due to various constraints or risks, swabbing serves as a method to collect samples using a sterile swab. This technique involves using aseptic procedures to prevent contamination, where the sterile swab is soaked in sterile water before collecting the sample. After which, the sample can be cultured on a TSA plate and further analyzed with methods such as gram staining to determine cell morphology and arrangement.
