Final answer:
Physicians prescribe, pharmacists dispense and provide medication advice, and nurses observe and administer medications, all playing roles in recommending and managing patient medication.
Step-by-step explanation:
The entities that are generally responsible for recommending medications that treat a patient are A) Physician, Pharmacist, and Nurse. The physician diagnoses the patient and prescribes medication. The pharmacist, who must hold a doctorate in pharmacy, dispenses these drugs and can advise both physicians and patients on drug selection, dosage, interactions, and side effects. Nurses also play a key role in patient care and may recommend adjustments based on their observations of a patient's response to treatment while also ensuring the proper administration of medication.
