Final answer:
It is false that only healthcare professionals can make referrals to medical treatment (MT). Self-referral is possible in some healthcare systems, although it is more common for healthcare professionals to make referrals.
Step-by-step explanation:
The statement 'Only a healthcare professional can make a referral to MT.' is false. While healthcare professionals often make referrals to medical treatment (MT), there are instances where self-referral is possible. In some healthcare systems, individuals can refer themselves directly to certain medical specialists or for specific procedures and therapies. The specifics can depend on the health policy of a particular country, insurance details, or the healthcare system in place. However, it's most common for primary care physicians or other healthcare providers to assess a patient's condition and then make a referral to a specialist or additional treatment options as necessary.
