Tick the unwanted effects of Metronidazole:

Correct Answer: A

Rationale: The correct answer is A because nausea, vomiting, diarrhea, and stomatitis are common side effects of Metronidazole. Hypertension and disturbances of peripheral blood circulation are not typically associated with Metronidazole use. Therefore, choice A is the only option that accurately reflects the unwanted effects of Metronidazole.

Correct Answer: A

Rationale: The correct answer is A: Verapamil. Verapamil is a calcium channel blocker that can help prevent delayed cerebral ischemia by reducing vasospasm in the blood vessels in the brain. This is important in patients with blood in the subarachnoid space, as vasospasm can lead to decreased blood flow and subsequent ischemia. Isosorbide mononitrate (B) and Propranolol (C) are not typically used for preventing cerebral vasospasm. Dobutamine (D) is a positive inotrope and is not indicated for preventing cerebral vasospasm.

Correct Answer: B

Rationale: The correct answer is B: Amiodarone. Amiodarone is the most appropriate choice because it is a Class III antiarrhythmic drug that is effective in treating various types of arrhythmias, including ventricular and atrial arrhythmias. It works by prolonging the action potential duration and refractory period of cardiac tissue, helping to stabilize the heart's rhythm. Quinidine (A) is a Class I antiarrhythmic drug with potential side effects and limited efficacy. Verapamil (C) is a calcium channel blocker that is more suitable for treating certain types of supraventricular arrhythmias but not as effective for other types. Propranolol (D) is a beta-blocker that may be used for certain arrhythmias, but it is not as effective or versatile as amiodarone for treating various types of arrhythmias.
