Review HESI Fundamentals Exam related questions and content

A healthcare professional is planning to collect a liquid stool specimen from a client for ova and parasites. Inaccurate test results may result if the healthcare professional:

  • A. Refrigerates the collected specimen
  • B. Collects the specimen in a sterile container
  • C. Delays the collection of the specimen
  • D. Uses a non-contaminated collection container
Correct Answer: A

Rationale: Refrigeration can kill the ova and parasites present in the stool specimen, leading to inaccurate test results. Storing the specimen in a cold environment can disrupt the integrity of the parasites and ova, affecting the accuracy of the test. Collecting the specimen in a sterile container (Choice B) is the correct procedure to prevent external contamination. Delaying the collection of the specimen (Choice C) may affect the freshness of the sample but does not directly impact the test results. Using a non-contaminated collection container (Choice D) is essential to maintain the sample's integrity but does not relate to the risk of killing ova and parasites through refrigeration.
