Tick the drug which belongs to nonnucleoside reverse transcriptase inhibitors:

Correct Answer: C

Rationale: Step-by-step rationale: 1. Nonnucleoside reverse transcriptase inhibitors (NNRTIs) bind to the enzyme reverse transcriptase. 2. Nevirapine is an NNRTI that inhibits HIV-1 reverse transcriptase. 3. Zidovudine (A) is a nucleoside reverse transcriptase inhibitor. 4. Vidarabine (B) is a nucleoside analog antiviral medication. 5. Gancyclovir (D) is a nucleoside analog antiviral used for herpesvirus infections. Summary: Choice C (Nevirapine) is the correct answer as it belongs to the class of NNRTIs by inhibiting reverse transcriptase enzyme. Choices A, B, and D are incorrect as they belong to the class of nucleoside analog antivirals, not NNRTIs.

Correct Answer: B

Rationale: The correct answer is B, Diazoxide and hydralazine. Diazoxide is a vasodilator used to treat hypertension emergencies, while hydralazine is also a vasodilator commonly used for hypertensive crises. Both drugs have fast-acting properties and are often administered together to rapidly reduce blood pressure. A (Labetalol and prazosin) is incorrect because Labetalol is a beta-blocker and prazosin is an alpha-blocker, which are not commonly administered together for hypertensive emergencies. C (Clonidine and captopril) is incorrect because Clonidine is a centrally acting alpha-2 agonist and captopril is an ACE inhibitor, which are not typically used together for acute hypertension. D (Nitroprusside and esmolol) is incorrect because Nitroprusside is a potent vasodilator and esmolol is a beta-blocker, but they are not usually administered together
