Question 1

Which type of microorganism is responsible for the majority of urinary tract infections (UTIs)?

Accepted Answer

Bacteria

The vast majority of UTIs are caused by bacteria, most commonly Escherichia coli, which accounts for approximately 80–85% of community-acquired UTIs.

Question 2

What is the purpose of a culture and sensitivity (C&S) test?

Accepted Answer

To identify the causative organism of an infection and determine which antibiotics will be effective

Answer

A culture and sensitivity test identifies the specific microorganism causing an infection (culture) and then tests which antibiotics are effective at killing or inhibiting it (sensitivity/susceptibility testing).

Question 3

A throat swab for a rapid strep test should be collected by swabbing which area?

Accepted Answer

The posterior pharynx and tonsillar areas

Answer

For a throat culture or rapid strep test, the swab must be applied firmly to the posterior pharynx (back of the throat) and tonsillar areas or any visible exudate or inflamed areas.

Question 4

Which personal protective equipment (PPE) is required when handling potentially infectious specimens in a medical office?

Accepted Answer

Gloves at minimum; additional PPE based on risk assessment

Answer

Standard precautions require gloves when handling any potentially infectious material. Additional PPE (gown, mask, eye protection) is used based on the risk of splash or aerosol exposure.

Question 5

What is the correct way to label a specimen container before collection?

Accepted Answer

Label it in the collection room immediately after the specimen is obtained

Answer

Specimen containers should be labeled immediately after collection in the presence of the patient, after the specimen has been obtained, to ensure correct patient-to-specimen identification.
