Final answer:
D) An aerobic bottle and an anaerobic bottle. The phlebotomist should bring an aerobic bottle and an anaerobic bottle to collect blood cultures in the ICU.
Step-by-step explanation:
The phlebotomist should bring an aerobic bottle and an anaerobic bottle to collect blood cultures in the ICU. Blood cultures are used to identify the presence of bacteria or fungi in the bloodstream, which can help diagnose infections. By bringing both types of bottles, the phlebotomist can ensure that both aerobic (requiring oxygen) and anaerobic (not requiring oxygen) bacteria can be detected.
