Tick the group of drugs used as subsidiary medicines in cancer treatment:

Correct Answer: D

Rationale: The correct answer is D: All of the above. Cytoprotectors help protect healthy cells from damage caused by cancer treatment. Bone marrow growth factors aid in stimulating the production of blood cells, which can be suppressed during cancer treatment. Antimetastatic agents help prevent the spread of cancer to other parts of the body. Therefore, all these groups of drugs are used as subsidiary medicines in cancer treatment to support the primary treatment and manage side effects. Choices A, B, and C are incorrect individually because each group plays a specific role in supporting cancer treatment, making the combination of all three necessary for comprehensive care.

Correct Answer: D

Rationale: The correct answer is D: Amiodarone. Amiodarone is a potent antiarrhythmic drug commonly used to prevent fibrillatory episodes like atrial fibrillation. It has a broad spectrum of action, affecting multiple ion channels to stabilize cardiac rhythm. Mexiletine (A) is used for ventricular arrhythmias, not fibrillatory episodes. Sotalol (B) is also used for ventricular arrhythmias and can actually increase the risk of torsades de pointes in patients with atrial fibrillation. Quinidine (C) is an older antiarrhythmic that is less commonly used due to its potential for proarrhythmic effects.
