In medical terminology, the prefix 'cardio-' is derived from the Greek word "kardia," meaning heart. It is commonly used in terms like cardiology (study of the heart), cardiovascular (relating to the heart and blood vessels), and cardiomyopathy (disease of the heart muscle). Understanding this prefix helps in deciphering many medical terms related to the circulatory system.

The suffix '-itis' is a common medical term used to denote inflammation of an organ or tissue. For example, appendicitis refers to inflammation of the appendix, bronchitis is inflammation of the bronchi, and arthritis is inflammation of the joints. Recognizing this suffix helps in understanding various inflammatory conditions.

Question 3

What class of drug is used to reduce pain?

Accepted Answer

Analgesics

Answer

Analgesics are a class of drugs specifically designed to relieve pain without causing loss of consciousness. They work through various mechanisms to reduce the perception of pain, ranging from over-the-counter options like ibuprofen and acetaminophen to stronger prescription opioids. This makes them distinct from other drug classes like antipyretics (fever reducers) or antibiotics (infection fighters).

Question 4

Which of the following is a beta-blocker?

Accepted Answer

Metoprolol

Answer

Metoprolol is a well-known medication that belongs to the class of drugs called beta-blockers, which are primarily used to treat cardiovascular conditions like high blood pressure, angina, and heart failure. Beta-blockers work by blocking the effects of adrenaline on the heart and blood vessels, slowing the heart rate and relaxing blood vessels. The other options (Lisinopril, Furosemide, Omeprazole) belong to different drug classes.

Question 5

What does 'subcutaneous' refer to?

Accepted Answer

Under the skin

Answer

The term 'subcutaneous' is a medical directional term derived from Latin. 'Sub-' means under, and 'cutaneous' refers to the skin. Therefore, a subcutaneous injection or administration means introducing a substance into the layer of tissue directly beneath the skin, but above the muscle.
