Question 1 of 9
Which of the following conditions is not treated with Ephedrine?
Correct Answer: A
Rationale: The correct answer is A: COPD. Ephedrine is a sympathomimetic drug that acts on alpha and beta adrenergic receptors, leading to vasoconstriction and increased heart rate. It is used to treat hypotension and congestion by increasing blood pressure and dilating airways, respectively. Incontinence is not typically treated with Ephedrine. However, COPD involves bronchoconstriction, which can worsen with Ephedrine due to its vasoconstrictive effects. Therefore, Ephedrine is not used to treat COPD.
Question 2 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.
Question 3 of 9
Which of the following is not directly related to the drug toxicity of Ibuprofen?
Correct Answer: D
Rationale: The correct answer is D: Muscle wasting. Ibuprofen is primarily associated with gastrointestinal side effects like nausea, renal dysfunction, and anemia due to its effects on the stomach, kidneys, and blood. Muscle wasting is not a known direct effect of Ibuprofen toxicity. Ibuprofen is not typically linked to muscle-related issues, making choice D the correct answer.
Question 4 of 9
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 5 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 6 of 9
Which of the following is not a side effect associated with Prednisone toxicity?
Correct Answer: B
Rationale: The correct answer is B: Hypotension. Prednisone toxicity typically causes hypertension, not hypotension. Prednisone can lead to increased blood pressure due to its sodium-retaining effects. Cataracts (A), Psychosis (C), and Acne (D) are all known side effects of Prednisone toxicity. Cataracts can form due to long-term steroid use, psychosis can occur especially at higher doses, and acne is a common skin side effect. Therefore, hypotension is the odd one out among the choices given.
Question 7 of 9
Which of the following conditions is not treated with Lansoprazole?
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.
Question 8 of 9
Which of the following conditions are not treated with Barbiturates?
Correct Answer: B
Rationale: Barbiturates are central nervous system depressants used to treat seizures, insomnia, and anxiety. However, they can worsen hypotension as they can cause vasodilation and decrease blood pressure. Choice B is correct because using barbiturates in hypotensive patients can lead to further lowering of blood pressure, potentially causing harm. Choices A, C, and D are incorrect as barbiturates are commonly used to treat seizures, insomnia, and anxiety, respectively, due to their sedative and anticonvulsant properties.
Question 9 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.
