Which of the following is not a side effect of the vasodilator Nifedipine?

Correct Answer: D

Rationale: The correct answer is D: Sexual dysfunction. Nifedipine is a calcium channel blocker that primarily causes vasodilation by relaxing blood vessels. Sexual dysfunction is not a common side effect associated with Nifedipine use. Nausea, flushed appearance, and vertigo are potential side effects of Nifedipine due to its mechanism of action on the cardiovascular system. Therefore, D is the correct choice as it does not align with the expected side effects of Nifedipine.

Correct Answer: D

Rationale: Explanation: Dexamethasone is a corticosteroid used to treat inflammation and conditions like asthma and Addison's disease, which involve inflammation or immune responses. Wilson's disease is a genetic disorder related to copper metabolism, not treated with Dexamethasone. Dexamethasone could worsen Wilson's disease due to its potential impact on copper levels.

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.

Correct Answer: A

Rationale: The correct answer is A: Hypertension is not a side effect of Sympathoplegics (Clonidine). Sympathoplegics are medications that inhibit the sympathetic nervous system, leading to decreased heart rate and blood pressure. Therefore, hypertension is not a common side effect. Choices B, C, and D are incorrect because difficulty breathing, dry oral cavity, and lethargic behavior are potential side effects of Sympathoplegics due to their central nervous system depressant effects.

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.

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.

Correct Answer: D

Rationale: Step-by-step rationale: 1. Midazolam is a benzodiazepine commonly used as a sedative and anxiolytic. 2. Common effects of Midazolam include amnesia, decreased respiratory function, and anesthetic properties. 3. Dizziness is not a common effect of Midazolam but can be a side effect in some individuals. 4. Therefore, choice D (Dizziness) is not a common effect of Midazolam, making it the correct answer. Summary: - A: Amnesia - Common effect of Midazolam - B: Decreased respiratory function - Common effect of Midazolam - C: Anesthetic - Common effect of Midazolam - D: Dizziness - Not a common effect of Midazolam, making it the correct answer.

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.

Correct Answer: B

Rationale: The correct answer is B: Diarrhea. Atropine, a cholinoreceptor blocker, inhibits acetylcholine, causing decreased GI motility leading to constipation. Atropine also increases pulse rate due to reduced vagal tone (A). It causes mydriasis by blocking cholinergic receptors in the eye (D). Diarrhea is not a typical side effect of atropine due to its anticholinergic properties.
