Question 1 of 5
Which of the following drugs is associated with hepatitis as a reaction?
Correct Answer: C
Rationale: Correct Answer: C (Isoniazid) Rationale: 1. Isoniazid is known to cause drug-induced hepatitis due to its hepatotoxic effects. 2. It can lead to liver inflammation, causing hepatitis as a reaction. 3. Regular monitoring of liver function tests is essential when using isoniazid. Summary of other choices: A. Valproic acid: Can cause hepatotoxicity but not specifically linked to hepatitis. B. Quinidine: Mainly known for cardiac side effects, not commonly associated with hepatitis. D. Ethosuximide: Primarily used for treating absence seizures, not typically associated with hepatitis.
Question 2 of 5
Which of the following drugs is associated with the reaction of tendon dysfunction?
Correct Answer: D
Rationale: The correct answer is D: Fluoroquinolones. Fluoroquinolones are known to be associated with tendon dysfunction due to their potential to cause tendinitis and tendon rupture. This adverse effect is thought to be related to the drug's ability to disrupt collagen synthesis and structure in tendons. Digitalis (A) is used to treat heart conditions, niacin (B) for cholesterol, and tetracycline (C) for bacterial infections, none of which are linked to tendon dysfunction.
Question 3 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 4 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 5 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.
