A drug that has no therapeutic effect
- A. potency
- B. quality
- C. efficacy
- D. placebo
Correct Answer: D
Rationale: Placebo' is correct because it's a substance with no therapeutic effect, used in trials to compare against active drugs. 'Potency' is a drug's strength, implying effect. 'Quality' is manufacturing standard, not effect. 'Efficacy' is therapeutic capability, opposite of placebo. Originally 'e' (correct), it replaces 'd' (purity) per instructions, ensuring four choices. Placebos are standard in pharmacology for testing patient response versus drug action.

A drug with low abuse indication and may be bought OTC
- A. Schedule I
- B. Schedule II
- C. Schedule III
- D. Schedule V
Correct Answer: D
Rationale: Schedule V' is correct because these drugs (e.g., cough syrups with codeine) have the lowest abuse potential and can be sold over-the-counter in limited cases under DEA rules. 'Schedule I' has no medical use. 'Schedule II' and 'III' require prescriptions due to higher risk. 'Schedule IV' needs prescriptions too. Schedule V's minimal risk allows OTC access, per regulatory standards.
Standardization of drugs began
- A. in the nineteenth century
- B. in the twentieth century
- C. after 1950
- D. Drugs have always been standardized.
Correct Answer: B
Rationale: The twentieth century is correct because drug standardization, as a formal process, emerged with legislation like the 1906 Pure Food and Drug Act and grew with the FDA's establishment in 1938. The nineteenth century saw early efforts, but not systematic standardization. 'After 1950' is too late, missing key early reforms. 'Drugs have always been standardized' is false—before modern regulation, drug quality varied widely. The twentieth century marks the era of consistent standards, as pharmacology texts note.
Which drug legislation act was instrumental for the growth of electronic prescribing?
- A. Controlled Substance Act
- B. Medicare Modernization Act
- C. Food, Drug and Cosmetic Act
- D. Harrison Narcotic Act
Correct Answer: B
Rationale: The Medicare Modernization Act (B) of 2003 boosted e-prescribing, per the text, making it correct. A, C, and D are unrelated to this growth, confirming B.
NSAIDs are used in combination with which of the following drugs to decrease its side effects?
- A. Fluvastatin
- B. Lovastatin
- C. Evinacumab
- D. Niacin
Correct Answer: D
Rationale: D' is correct because niacin's side effects (e.g., flushing) can be mitigated by NSAIDs like aspirin, per clinical practice. 'A' and 'B' (statins) and 'C' (evinacumab) don't typically pair with NSAIDs for side effect reduction. Niacin's prostaglandin-mediated flushing is uniquely responsive to this combo.
The nurse administers a prescribed medication that is supplied as an enteric-coated tablet. The patient asks the nurse about this form of tablet. When describing how this tablet is absorbed, which response by the nurse would be most accurate?
- A. The medication dissolves directly from the stomach into the body
- B. The drug breaks up into pieces as it moves through the stomach
- C. The medication bypasses the GI tract and goes quickly into the bloodstream
- D. The drug dissolves into fragments after it reaches your small intestine
Correct Answer: D
Rationale: Enteric-coated tablets dissolve in the small intestine (D), per the text. Stomach dissolution (A, B) is incorrect due to the coating, and bypassing GI (C) is false. The text explains the alkaline-triggered release, making D the most accurate response.
