Question 1 of 5

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 2 of 5

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 5

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

Correct Answer: C

Rationale: The correct answer is C: Antifungal. Drugs ending in the suffix (azole) are commonly used to treat fungal infections. The suffix indicates that the drug belongs to the azole class, which specifically targets fungal pathogens by inhibiting their growth. Therefore, a drug ending in (azole) is classified as an antifungal medication. Summary of other choices: A: H - Incorrect. There is no pharmacological relevance to the suffix (azole) in relation to the letter H. B: ACE inhibitor - Incorrect. Drugs ending in (pril) are commonly ACE inhibitors, not those ending in (azole). D: Beta agonist - Incorrect. Drugs ending in (ol) or (olol) are typically beta agonists, not those ending in (azole).

Question 4 of 5

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

Correct Answer: D

Rationale: The correct answer is D: H antagonist. Drugs ending in the suffix (tidine) typically belong to the class of histamine H2-receptor antagonists. These drugs work by blocking the action of histamine on H2 receptors in the stomach, reducing the production of stomach acid. This is commonly used to treat conditions such as peptic ulcers and gastroesophageal reflux disease. Explanation of other choices: A: Antidepressant - Drugs ending in (pramine) or (ine) are more commonly associated with antidepressants. B: Protease inhibitor - Drugs ending in (navir) are typically protease inhibitors used in antiviral therapy. C: Beta antagonist - Drugs ending in (olol) are beta-blockers, which are used to treat conditions such as hypertension and heart disease, not related to (tidine) suffix.

Question 5 of 5

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).
