Question 1: Which drug classification includes medications like ibuprofen and aspirin used to reduce inflammation?
- NSAIDs (Correct answer)
- Opioids
- Antihistamines
- Beta-blockers
Correct answer: NSAIDs
NSAIDs (nonsteroidal anti-inflammatory drugs) reduce inflammation by inhibiting COX enzymes that produce prostaglandins.
Question 2: What is the term for an unintended, harmful reaction to a medication at a normal therapeutic dose?
- Adverse drug reaction (Correct answer)
- Drug tolerance
- Drug dependence
- Placebo effect
Correct answer: Adverse drug reaction
An adverse drug reaction (ADR) is an unintended harmful response to a medication given at a standard dose.
Question 3: Which route of drug administration bypasses the digestive system and delivers medication directly into the bloodstream?
- Intravenous (Correct answer)
- Oral
- Rectal
- Sublingual
Correct answer: Intravenous
Intravenous (IV) administration delivers drugs directly into a vein, bypassing the gastrointestinal tract for immediate effect.
Question 4: What schedule classification under the DEA applies to drugs with high abuse potential but accepted medical use, such as oxycodone?
- Schedule II (Correct answer)
- Schedule I
- Schedule III
- Schedule IV
Correct answer: Schedule II
Schedule II drugs have a high potential for abuse with accepted medical uses and require a written prescription with no refills.
Question 5: When two drugs are taken together and one increases the effect of the other beyond what either would produce alone, this is called:
- Synergism
- Antagonism
- Tolerance
- Potentiation (Correct answer)
Correct answer: Potentiation
Potentiation occurs when one drug enhances the effect of another drug, producing a greater combined effect than each drug alone.
Question 6: Which term describes the concentration of a drug in the bloodstream needed to produce a therapeutic effect?
- Therapeutic level (Correct answer)
- Toxic level
- Loading dose
- Bioavailability
Correct answer: Therapeutic level
The therapeutic level is the plasma drug concentration range that produces the desired clinical effect without causing toxicity.
