A practical nurse is reinforcing home collection instructions for a guaiac-based fecal occult blood test (gFOBT) as part of a routine colorectal cancer screening for an older adult client. In what chronological order should the nurse instruct the client to complete the following steps?
- 1Abstain from consuming red meat, vitamin C supplements, and NSAIDs for at least three days prior to collection.
- 2Defecate into a clean, dry collection container or plastic wrap placed over the toilet bowl.
- 3Use the provided applicator stick to apply a thin smear of stool to the first window of the test card.
- 4Obtain a second sample from a completely different area of the same stool and smear it on the second window.
- 5Close the cardboard flap and store the completed card at room temperature away from moisture and heat.
Answer
The correct sequence begins with necessary dietary and medication restrictions three days prior, followed by proper collection of the specimen without water contamination, applying the first smear, applying the second smear from a different area of the stool, and finally sealing and storing the card properly.
To ensure an accurate screening for colorectal cancer (a key component of health promotion and secondary prevention), the client must first follow dietary and medication restrictions to avoid false results. Once properly prepared, the stool must be collected in a clean, dry environment to avoid contamination from toilet water. The client then smears a sample on the first window, followed by a second sample from a completely different area of the stool on the second window, maximizing the chance of detecting unevenly distributed occult blood. Finally, the card is sealed and stored properly to preserve the specimen until laboratory analysis.
