Final answer:
Rodrigo's primary duties as a clinical laboratory technologist likely include collecting and analyzing blood samples and ordering medical equipment, while tasks like janitorial services and patient counseling are not typical responsibilities for his role.
Step-by-step explanation:
Rodrigo, as a clinical laboratory technologist at a hospital, has main responsibilities that involve processing and testing of bodily fluids to aid in the healthcare of patients. The two duties he might be most likely involved with include: collecting and analyzing blood samples as part of his expertise in phlebotomy, and potentially ordering medical equipment that is essential for laboratory operations.
As his role requires specialized knowledge, tasks such as performing janitorial services or providing counseling to patients generally fall outside of his primary duties and are more associated with other teams or departments within the hospital setting.
