Final answer:
Isosorbide dinitrate SL tablets must be dispensed in child-resistant containers. Oral administration is suitable for antimicrobials treating systemic infections at home. Avermectins are a drug class that inhibits neuronal transmission in helminths.
Step-by-step explanation:
Among the options given, the medication that needs to be dispensed in a child-resistant container is A) Isosorbide dinitrate SL tablets. These tablets are typically used for the treatment of angina pectoris and must be kept in containers that prevent children from accidentally ingesting them. The Poison Prevention Packaging Act mandates child-resistant packaging for many medications to reduce the risk of poisoning in children. Other medications like Mebendazole, Metformin, and Methylprednisolone do not necessarily require child-resistant containers, but pharmacies often use them as a standard precaution.
For the administration of an antimicrobial to treat a systemic infection at home, the most appropriate and convenient route is A. oral. Oral administration is less invasive and more straightforward for patients to manage compared to other routes like intravenous or parenteral, and it does not require the supervision of a healthcare professional.
The drug class that specifically inhibits neuronal transmission in helminths, thus treating parasitic worm infections, is B. avermectins. This class includes drugs that act by binding to certain chloride channels in the nerve and muscle cells of helminths, causing paralysis and death of the parasites.
