Final answer:
To prevent others from learning about a patient's private health information when waiting for prescriptions, measures such as speaking in a low voice, putting medications in a bag, and establishing a private area for counseling can be taken.
Step-by-step explanation:
To prevent others waiting for prescriptions from learning about the patient's private health information, there are several measures that can be taken. Speaking in a low voice when discussing private health information ensures that only the patient and the healthcare professional can hear the conversation. Putting medications in a bag provides an additional layer of privacy, as it prevents others from seeing which medications the patient is picking up. Finally, establishing a private area for counseling allows for confidential discussions about the patient's health conditions and concerns.
