Question 1 of 9

Which of the following is not a side effect of the cholinoreceptor blocker (Atropine)?

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.

Question 2 of 9

A drug ending in the suffix (pril) is considered a ______.

Correct Answer: B

Rationale: The correct answer is B: ACE inhibitor. Drugs ending in the suffix (-pril) typically refer to ACE inhibitors, which are commonly used to treat hypertension and heart failure by inhibiting the angiotensin-converting enzyme. ACE inhibitors do not belong to the categories mentioned in the other choices. Choice A (H) is vague and does not provide any relevant information. Choice C (Antifungal) is incorrect as drugs ending in (-pril) are not typically used to treat fungal infections. Choice D (Beta agonist) is also incorrect as drugs ending in (-pril) do not belong to the class of beta agonists, which are used to treat conditions like asthma and COPD.

Question 3 of 9

Which of the following is not an effect of the drug isoflurane?

Correct Answer: A

Rationale: The correct answer is A: Elevated lipid levels. Isoflurane does not cause elevated lipid levels. Isoflurane is a general anesthetic that primarily affects the central nervous system, leading to effects like decreased respiratory function and increased blood flow to the brain. Nausea can also be a side effect of isoflurane due to its impact on the gastrointestinal system. However, there is no direct link between isoflurane and elevated lipid levels. Thus, choice A is the correct answer.

Question 4 of 9

Which of the following is not a side effect of the ACE Inhibitor (Captopril)?

Correct Answer: D

Rationale: The correct answer is D: Congestion. ACE Inhibitors like Captopril do not typically cause congestion as a side effect. The main reason is that ACE inhibitors work by dilating blood vessels, which helps reduce blood pressure and improve blood flow. Congestion is more commonly associated with conditions like allergies or upper respiratory infections. A: Rash - Possible side effect of ACE inhibitors, but not specific to Captopril. B: Angioedema - Rare but serious side effect of ACE inhibitors, including Captopril. C: Cough - Common side effect of ACE inhibitors due to increased bradykinin levels.

Question 5 of 9

Which of the following drugs is associated with Stevens-Johnson syndrome?

Correct Answer: D

Rationale: Step 1: Ethosuximide is the correct answer as it is a known trigger for Stevens-Johnson syndrome due to its association with hypersensitivity reactions. Step 2: Valproic acid can cause liver toxicity but is not typically linked to Stevens-Johnson syndrome. Step 3: Quinidine is associated with drug-induced lupus but not commonly known to cause Stevens-Johnson syndrome. Step 4: Isoniazid is linked to drug-induced hepatitis but not typically associated with Stevens-Johnson syndrome. In summary, Ethosuximide is the correct choice due to its well-documented association with Stevens-Johnson syndrome, while the other options are linked to different adverse effects.

Question 6 of 9

Which of the following is the antidote for Heparin toxicity?

Correct Answer: A

Rationale: Protamine is the antidote for Heparin toxicity because it binds to Heparin and forms a stable complex, neutralizing its anticoagulant effects. Protamine sulfate is positively charged, while Heparin is negatively charged, allowing them to bind effectively. Methylene blue is used to treat methemoglobinemia, not Heparin toxicity. N-acetylcysteine is used for acetaminophen overdose, and Glucagon is used for beta-blocker overdose.

Question 7 of 9

Which of the following is not related to drug toxicity of Atenolol?

Correct Answer: B

Rationale: The correct answer is B: Tachycardia. Atenolol is a beta-blocker that works by slowing down the heart rate, so tachycardia is not related to its toxicity. A: CHF can be exacerbated by Atenolol due to its negative inotropic effects. C: AV block can occur as Atenolol can further slow down the heart's conduction system. D: Sedative appearance can be a side effect of Atenolol due to its action on the central nervous system. In summary, tachycardia is not related to Atenolol toxicity because it decreases heart rate.

Question 8 of 9

Which of the following is considered a class IA Sodium Channel blocker?

Correct Answer: D

Rationale: The correct answer is D: Procainamide. Procainamide is a class IA antiarrhythmic drug that blocks sodium channels, prolonging the action potential duration. This helps to stabilize the heart's rhythm. Mexiletine (A) is a class IB antiarrhythmic drug that blocks sodium channels with fast recovery kinetics. Amiodarone (B) is a class III antiarrhythmic drug that prolongs repolarization by blocking potassium channels. Quinidine (C) is a class IA antiarrhythmic drug that also blocks sodium channels, but it is not a class IB sodium channel blocker like Procainamide.

Question 9 of 9

A drug ending in the suffix (navir) is considered a ______.

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).
