Introduction to Pharmacology Questions and Answers

Answer: A

The correct matching is a-III, b-I, c-IV, d-II.

• Atropine (a): an anticholinergic that dries up secretions, used against excessive salivation, III.
• Betadine (b): povidone-iodine, an antiseptic, I.
• Dopamine (c): used to support the heart and blood pressure in shock and cardiac arrest, IV.
• Heparine (d): heparin, an anticoagulant, II.

Option B gives Betadine the anticoagulant role, and options C and D misplace atropine.

Answer: C

The incorrect statement is that pharmacokinetics describes the chemical composition and formulations of drugs.

Pharmacokinetics is the study of what the body does to a drug: its absorption, distribution, metabolism and excretion. The chemical composition and formulation of drugs is the subject of pharmaceutical chemistry and pharmaceutics (pharmacy).

The other three are correct: pharmacology is the study of drugs, pharmacotherapy is treatment of disease with medicines, and pharmacodynamics is the study of what a drug does to the body, its mechanism of action.
