Which benzodiazepines are commonly used as sleep aids? Select all that apply.

Correct Answer: A

Rationale: The correct answers for benzodiazepines commonly used as sleep aids are Temazepam. Temazepam is a benzodiazepine that is specifically indicated for the treatment of insomnia. It has a relatively short onset of action and duration of effect, making it suitable for sleep induction. Flurazepam is also used as a sleep aid due to its long half-life, but it is less commonly prescribed compared to Temazepam. Chlor diazepoxide and Triazolam are not typically used as sleep aids. Chlor diazepoxide is more commonly used for alcohol withdrawal and anxiety disorders, while Triazolam is used for the short-term treatment of insomnia but has a higher potential for abuse and dependence compared to Temazepam.

Correct Answer: C

Rationale: The correct answer is C because drug interactions occur when one drug alters the effect of another drug by affecting its pharmacokinetic or pharmacodynamic properties. This can lead to either potentiation or reduction of the drug's effects. Choice A is incorrect as toxic dosages do not necessarily lead to drug interactions. Choice B is incorrect as an increase in pharmacodynamics of bound drugs does not necessarily involve interactions with other drugs. Choice D is incorrect because an increase in drug excretion does not directly relate to drug interactions.

Correct Answer: C

Rationale: The correct answer is C: Fluconazole. This drug is appropriate for the patient likely suffering from a fungal infection like Candida. Nystatin (A) is also an antifungal but is more commonly used topically. Metronidazole (B) is an antibiotic used for bacterial infections. Acyclovir (D) is an antiviral used for herpes infections. In this case, the patient's symptoms point towards a fungal infection, making Fluconazole the most suitable choice.

Correct Answer: C

Rationale: Rationale: 1. Candida albicans is a type of yeast commonly causing fungal infections. 2. Nystatin is an antifungal medication effective against Candida species. 3. Nystatin works by binding to fungal cell membranes and disrupting their integrity. 4. Griseofulvin (Choice A) is used to treat fungal skin infections, not Candida. 5. Terbinafine (Choice B) is mainly used for dermatophyte infections, not Candida. 6. Caspofungin (Choice D) is more suitable for invasive fungal infections like aspergillosis, not Candida. Summary: - Choice A, B, and D are incorrect because they do not target Candida albicans specifically. - Choice C is correct as nystatin is the appropriate treatment for Candida albicans infections.

Correct Answer: A

Rationale: The correct answer is A: Muscle pain. Statins are known to cause myopathy, a condition characterized by muscle pain or weakness. This is due to statins affecting the production of Coenzyme Q10, which is essential for muscle function. Other choices are incorrect because weight loss is not a common side effect of statins; dizziness is more commonly associated with blood pressure medications or other classes of drugs; and statins are actually used to help lower blood pressure in patients with hypertension, so it is not a common side effect of statins.
