Question

a patient goes to the hospital with large pimples on the chest. the test for s. aureus returns positive on the skin, but negative in the blood. the patient is therefore colonized with s. aureus because it was only found on the skin.
true
false

Explanation:

Colonization refers to the presence of a microorganism on or in the body without causing infection (no spread to sterile sites like blood). Since S. aureus is found on the skin (a non-sterile site) but not in the blood (a sterile site), the patient is colonized. However, the reasoning is correct, but wait—wait, no: the statement says "because it was only found on the skin" which aligns with colonization. Wait, no, wait: no, colonization is when the microbe is present without disease. The test is positive on skin (colonization site) and negative in blood (no systemic infection). So why false? Wait, no—wait, maybe the pimples indicate infection? No, the statement says "colonized because only found on skin". Wait, no: colonization is presence without infection. If the pimples are due to S. aureus, that's infection, not colonization. Oh! The patient has large pimples (a sign of infection), so finding S. aureus on the skin with symptoms means it's an infection, not just colonization. So the statement is false because the presence of symptoms (pimples) indicates infection, not colonization.

Answer:

false
