"A culture identifies an antibiotic's effect on a pathogen."

"A culture determines the appropriate medication dose."

"A culture measures antibiotic levels."

"A culture identifies the presence of pathogens."

Answer and Explanation

The Correct Answer is D

A.   "A culture identifies an antibiotic's effect on a pathogen.": Cultures do not determine the effect of antibiotics on pathogens; they identify the presence of pathogens and their susceptibility to antibiotics.
B.   "A culture determines the appropriate medication dose.": Cultures do not determine medication doses; they identify pathogens and guide antibiotic selection based on susceptibility testing.
C.   "A culture measures antibiotic levels.": Cultures do not measure antibiotic levels; they identify pathogens and their susceptibility to antibiotics.
D.   "A culture identifies the presence of pathogens.": This is the correct explanation. A wound culture is performed to identify any microorganisms present in the wound, such as bacteria or fungi, which helps guide appropriate treatment.

A. Avoiding use of a urinary catheter B. Applying absorbent briefs C. Restricting Fluids D. Toileting patient every 4 hours

Correct Answer is B

Explanation

A. Avoiding use of a urinary catheter: While avoiding unnecessary urinary catheterization is important to prevent healthcare-associated urinary tract infections, this action may not be directly applicable to an incontinent patient who requires interventions to manage incontinence.
B. Applying absorbent briefs: Using absorbent briefs helps contain urine and feces, reducing the risk of skin breakdown and contamination of the environment.
C. Restricting Fluids: Restricting fluids may lead to dehydration and is not a recommended approach for preventing healthcare-associated infections in incontinent patients.
D. Toileting patient every 4 hours: Toileting frequency should be individualized based on the patient's needs and not restricted to a specific time interval. Additionally, simply toileting the patient may not be sufficient to prevent healthcare-associated infections if proper hygiene practices are not followed.
