Which of the following is not a side effect of the cholinoreceptor blocker (Atropine)?
- A. Increased pulse
- B. Diarrhea
- C. Constipation
- D. Mydriasis
Correct Answer: B
Rationale: The correct answer is B: Diarrhea. Atropine, a cholinoreceptor blocker, inhibits acetylcholine, causing decreased GI motility leading to constipation. Atropine also increases pulse rate due to reduced vagal tone (A). It causes mydriasis by blocking cholinergic receptors in the eye (D). Diarrhea is not a typical side effect of atropine due to its anticholinergic properties.

Which of the following is not a known effect of the drug Clozapine?
- A. Agranulocytosis
- B. Antipsychotic
- C. Used for Schizophrenia
- D. Hyperactivity
Correct Answer: D
Rationale: The correct answer is D: Hyperactivity. Clozapine is an antipsychotic drug used for schizophrenia treatment. Agranulocytosis is a known severe side effect of Clozapine. Hyperactivity is not a known effect of Clozapine, as it actually has a sedative effect due to its mechanism of action in the brain. Therefore, option D is the correct answer. Options A, B, and C are incorrect as agranulocytosis is a known side effect, Clozapine is an antipsychotic drug, and it is commonly used for schizophrenia treatment.
What is the antidote for copper toxicity?
- A. Glucagon
- B. Aminocaproic acid
- C. Atropine
- D. Penicillamine
Correct Answer: D
Rationale: The correct answer is D: Penicillamine. Penicillamine is a chelating agent that binds to copper and forms a complex that can be excreted from the body, making it an effective antidote for copper toxicity. Glucagon (A) is used for treating hypoglycemia, aminocaproic acid (B) is used to treat excessive bleeding, and atropine (C) is used to treat bradycardia and organophosphate poisoning, none of which are related to copper toxicity.
Which of the following conditions is not treated with Lansoprazole?
- A. Zollinger-Ellison syndrome
- B. Gastritis
- C. Hypertension
- D. Reflux
Correct Answer: C
Rationale: Rationale: Lansoprazole is a proton pump inhibitor used to reduce stomach acid production. Hypertension is a condition related to high blood pressure and is not treated with Lansoprazole. Zollinger-Ellison syndrome, gastritis, and reflux are all conditions that can be treated with Lansoprazole due to its ability to reduce stomach acid. Therefore, choice C is the correct answer.
A drug ending in the suffix (navir) is considered a ______.
- A. Antidepressant
- B. Protease inhibitor
- C. Beta antagonist
- D. H antagonist
Correct Answer: B
Rationale: The correct answer is B: Protease inhibitor. Drugs ending in the suffix (navir) are commonly used to inhibit protease enzymes in viruses, particularly in the treatment of HIV/AIDS. Protease inhibitors disrupt viral replication by preventing the cleavage of viral proteins, thus inhibiting the production of new infectious viral particles.
Choice A, Antidepressant, is incorrect as drugs used to treat depression usually end in (ine) or (pram).
Choice C, Beta antagonist, is incorrect as drugs affecting beta receptors typically end in (olol) or (lol).
Choice D, H antagonist, is incorrect as drugs targeting histamine receptors usually end in (ine) or (idine).
Which of the following is not directly related to drug toxicity of Nitroglycerin?
- A. Headaches
- B. Tachycardia
- C. Dizziness
- D. Projectile vomiting
Correct Answer: D
Rationale: The correct answer is D: Projectile vomiting. Nitroglycerin is not directly associated with causing projectile vomiting. Nitroglycerin commonly causes headaches due to vasodilation, tachycardia due to decreased preload, and dizziness due to hypotension. Projectile vomiting is not a typical side effect of Nitroglycerin toxicity.
