Local effects occur at which location?

• A. At the location on the body where the drug has touched
• B. Throughout the body
• C. Only in the bloodstream
• D. Within the bones

Answer: (A)

Local effects happen at the site of application—the area on the body where the drug touches. This occurs because the medication acts directly where it’s applied and remains localized unless it is absorbed into the bloodstream to produce systemic effects. So topical creams, ointments, or eye drops typically produce changes at that specific spot, not throughout the body. The other scenarios describe systemic distribution or an unlikely site for local action (like within bones).
