CNPR Pharmacology & Medical Terminology — Questions and Answers
Question 1: What does the term 'antipyretic' refer to?
- Pain reliever
- Anti-inflammatory
- Fever reducer (Correct answer)
- Blood thinner
Correct answer: Fever reducer
The term 'antipyretic' specifically refers to a class of drugs designed to reduce fever. These medications work by acting on the hypothalamus in the brain, which regulates body temperature, to lower an elevated body temperature. Common examples include acetaminophen and ibuprofen, which are widely used to alleviate fever symptoms.
Question 2: What is the medical abbreviation 'BID' commonly used for?
- Before bedtime
- Once daily
- Every four hours
- Twice a day (Correct answer)
Correct answer: Twice a day
BID is a common medical abbreviation derived from the Latin "bis in die," meaning "twice a day." Healthcare professionals use this shorthand to clearly communicate medication dosing schedules, ensuring patients take their prescribed drugs at the correct frequency. This helps maintain therapeutic drug levels and optimize treatment effectiveness.
Question 3: Which of the following medications is classified as an antihypertensive?
- Lisinopril (Correct answer)
- Metformin
- Simvastatin
- Omeprazole
Correct answer: Lisinopril
Lisinopril is an ACE inhibitor, a class of medications specifically designed to treat hypertension (high blood pressure). It works by relaxing blood vessels and reducing the volume of blood the heart pumps, thereby lowering blood pressure. The other options are for diabetes (Metformin), high cholesterol (Simvastatin), and acid reflux (Omeprazole).
Question 4: What is the meaning of the medical term 'tachycardia'?
- Slow heart rate
- High blood pressure
- Rapid heart rate (Correct answer)
- Irregular heart rhythm
Correct answer: Rapid heart rate
The medical term 'tachycardia' is derived from the Greek words 'tachys' (fast) and 'kardia' (heart). It refers to a condition where the heart beats unusually fast, typically over 100 beats per minute in adults. This is distinct from a slow heart rate (bradycardia) or irregular heart rhythm (arrhythmia).
Question 5: What is the purpose of a 'proton pump inhibitor' (PPI)?
- Relieve pain
- Lower blood sugar
- Reduce stomach acid (Correct answer)
- Increase heart rate
Correct answer: Reduce stomach acid
Proton pump inhibitors (PPIs) are a class of medications that work by irreversibly blocking the proton pumps in the stomach lining. These pumps are responsible for the final step in acid production. By inhibiting them, PPIs significantly reduce the amount of acid produced, making them effective for conditions like GERD and ulcers.
Question 6: Which organ is primarily affected by hepatitis?
- Heart
- Kidney
- Liver (Correct answer)
- Stomach
Correct answer: Liver
Hepatitis is an inflammation of the liver, often caused by viral infections (Hepatitis A, B, C, D, E), but can also be due to alcohol, drugs, or autoimmune diseases. The term itself, 'hepat-' refers to the liver, and '-itis' indicates inflammation. This condition impairs the liver's vital functions, such as detoxification and bile production.
Question 7: What does the prefix 'hyper-' in medical terminology mean?
- Low
- Slow
- High (Correct answer)
- None
Correct answer: High
The prefix 'hyper-' in medical terminology consistently denotes "above," "excessive," or "high." For example, 'hypertension' means high blood pressure, and 'hyperglycemia' means high blood sugar. Conversely, 'hypo-' means low.
Question 8: Which of the following is a side effect of opioids?
- Increased energy
- Constipation (Correct answer)
- Weight loss
- Hyperactivity
Correct answer: Constipation
Opioids work by binding to opioid receptors in the brain and spinal cord, reducing pain perception. However, these receptors are also present in the gastrointestinal tract, where their activation slows down gut motility. This common side effect, known as opioid-induced constipation, can be severe and requires management.
Question 9: What is the function of insulin in the human body?
- Stimulates hunger
- Raises blood pressure
- Lowers blood sugar (Correct answer)
- Increases heart rate
Correct answer: Lowers blood sugar
Insulin is a hormone produced by the pancreas that plays a crucial role in regulating blood glucose levels. It facilitates the uptake of glucose from the bloodstream into cells for energy or storage. Without sufficient insulin, glucose accumulates in the blood, leading to high blood sugar (hyperglycemia), as seen in diabetes.
