Question 1 of 9

Which of the following is not directly related to drug toxicity of Nitroglycerin?

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.

Question 2 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).

Question 3 of 9

Which of the following is the primary site of activity for the drug Warfarin?

Correct Answer: B

Rationale: The correct answer is B: Liver. Warfarin is primarily metabolized in the liver by the cytochrome P450 enzyme system. The liver is responsible for breaking down and activating many drugs, including Warfarin. It is where the drug's metabolism and effects are most significant. The other choices are incorrect because Warfarin's main site of activity is in the liver, not the kidney, blood, or heart. The kidney mainly excretes the drug, while the blood carries it throughout the body, and the heart is not directly involved in Warfarin's metabolism.

Question 4 of 9

Potassium-sparing diuretics primarily affect which part of the kidney?

Correct Answer: D

Rationale: The correct answer is D: Distal convoluted tubule. Potassium-sparing diuretics, such as spironolactone, act on the distal convoluted tubule by blocking the aldosterone receptor, which leads to decreased sodium reabsorption and potassium retention. This mechanism helps to promote diuresis while preventing potassium loss. Choices A, B, and C are incorrect because potassium-sparing diuretics do not primarily affect the proximal convoluted tubule, loop of Henle, or collecting duct in the kidney.

Question 5 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 6 of 9

Which of the following conditions is not treated with Methotrexate?

Correct Answer: D

Rationale: The correct answer is D: Rheumatic fever. Methotrexate is not typically used to treat rheumatic fever as it is an autoimmune inflammatory condition, not typically responsive to Methotrexate. Methotrexate is commonly used to treat sarcomas, leukemias, and ectopic pregnancies due to its ability to inhibit cell proliferation. Sarcomas and leukemias are types of cancers, while ectopic pregnancy is a condition where a fertilized egg implants outside the uterus.

Question 7 of 9

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 8 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 9 of 9

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.
