Which of the following is not directly related to drug toxicity of Nitroglycerin?
- A. Headaches
- B. Tachycardia
- C. Dizziness
- D. Projectile vomiting
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.

Which of the following conditions is not treated with Prednisone?
- A. Cushing's disease
- B. Testicular cancer
- C. Lymphomas
- D. Chronic leukemias
Correct Answer: B
Rationale: Prednisone is a corticosteroid used to treat inflammatory conditions and certain types of cancer. Testicular cancer is not typically treated with Prednisone because it is a form of cancer that requires specific treatments such as surgery, chemotherapy, or radiation therapy. Prednisone is not the primary treatment option for testicular cancer. In contrast, Prednisone is commonly used to manage symptoms in conditions like Cushing's disease, lymphomas, and chronic leukemias by reducing inflammation and suppressing immune response. Therefore, choice B is the correct answer as Prednisone is not a standard treatment for testicular cancer.
Which of the following is not a side effect of the ACE Inhibitor (Captopril)?
- A. Rash
- B. Angioedema
- C. Cough
- D. Congestion
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.
Potassium-sparing diuretics primarily affect which part of the kidney?
- A. Proximal convoluted tubule
- B. Loop of Henle
- C. Collecting duct
- D. Distal convoluted tubule
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.
Which of the following conditions is not treated with Lansoprazole?
- A. Zollinger-Ellison syndrome
- B. Gastritis
- C. Hypertension
- D. Reflux
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.
What is the antidote for copper toxicity?
- A. Glucagon
- B. Aminocaproic acid
- C. Atropine
- D. Penicillamine
Correct Answer: D
Rationale: The correct answer is D: Penicillamine. Penicillamine is a chelating agent that binds to copper and forms a complex that can be excreted from the body, making it an effective antidote for copper toxicity. Glucagon (A) is used for treating hypoglycemia, aminocaproic acid (B) is used to treat excessive bleeding, and atropine (C) is used to treat bradycardia and organophosphate poisoning, none of which are related to copper toxicity.
