Tick the antibiotic for cancer chemotherapy:

Correct Answer: B

Rationale: The correct answer is B: Doxorubicin. Doxorubicin is an antibiotic commonly used in cancer chemotherapy to treat various types of cancer. It works by inhibiting DNA and RNA synthesis in cancer cells, leading to cell death. Cytarabine (A) is an antimetabolite used in leukemia treatment, not an antibiotic for cancer chemotherapy. Gentamycin (C) is an aminoglycoside antibiotic used for bacterial infections, not cancer treatment. Etoposide (D) is a topoisomerase inhibitor used in cancer chemotherapy but is not classified as an antibiotic.

Correct Answer: D

Rationale: The correct answer is D (Nitroprusside and esmolol) for aortic dissection. Nitroprusside is a vasodilator to reduce afterload and esmolol is a beta-blocker to control heart rate and blood pressure. This combination helps decrease shear stress on the aorta. A: Labetalol is a beta-blocker and prazosin is an alpha-blocker, not commonly used for aortic dissection. B: Diazoxide is a vasodilator and hydralazine is an arterial dilator, not the first-line in aortic dissection. C: Clonidine is a centrally acting alpha-agonist and captopril is an ACE inhibitor, not typically used in aortic dissection management.
