Correct Answer is C

Explanation

Choice A rationale

Swabbing an area of skin away from the wound to identify the usual flora is not the correct action. This would not provide a representative sample of the wound infection.

Choice B rationale

Irrigating the wound with an antiseptic prior to obtaining the specimen is not the correct action. This could potentially alter the results of the culture.

Choice C rationale

Cleansing the wound with 0.9% sodium chloride saline irrigation before obtaining the specimen is the correct action. This helps to remove surface bacteria and ensures a more accurate culture result.

Choice D rationale

Including intact skin at the wound edges in the culture is not the correct action. This could contaminate the specimen with bacteria that are not part of the wound infection.

A. “The glomerular filtration rate (GFR) recovers.”. B. “Urine output is less than 400 mL per 24 hr.”. C. “Renal function is reestablished.”. D. “BUN and creatinine levels decrease.”.

Correct Answer is B

Explanation

Choice A rationale

The glomerular filtration rate (GFR) does not recover during the oliguric phase of acute kidney injury (AKI). Recovery of GFR typically occurs during the recovery phase.

Choice B rationale

During the oliguric phase of AKI, urine output is typically less than 400 mL per 24 hours.

Choice C rationale

Renal function is not reestablished during the oliguric phase of AKI. This typically occurs during the recovery phase.

Choice D rationale

Blood urea nitrogen (BUN) and creatinine levels do not decrease during the oliguric phase of AKI. These levels typically increase due to decreased kidney function.
