A. Pour the solution onto the gauze: This is the final step, performed after the solution has been poured into a receptacle to control the amount and maintain sterility of the gauze.

B. Place the bottle cap face-up on a clean surface: After removing the cap, placing it face-up on a clean surface prevents contamination of the inside of the cap and the solution.

C. Perform hand hygiene: Hand hygiene is the first step to reduce the risk of introducing microorganisms and maintain a sterile environment throughout the procedure.

D. Pick up the bottle with the label facing toward the palm: Holding the bottle with the label toward the palm prevents the label from getting wet or smeared, ensuring that the solution’s identity remains visible and accurate.

E. Pour 1 to 2 mL into a receptacle: Pouring a small amount first into a separate receptacle, also called “flushing” the lip of the bottle, removes any contaminants that may be present on the bottle rim, maintaining sterility of the solution applied to the gauze.

F. Remove the bottle cap: Removing the cap is done just before pouring to maintain sterility and prevent exposure of the solution to potential contaminants on the surrounding surfaces.

A. Antibiotics work solely by interacting with receptors on bacterial cells: Antibiotics act through several mechanisms, not just receptor interaction. Some disrupt cell wall synthesis, others inhibit protein production or interfere with nucleic acid metabolism.

B. All antibiotics have the same mechanism of action and therapeutic effects: Antibiotics differ widely in how they work and what infections they treat. Assuming uniform mechanisms ignores the diversity between classes such as beta-lactams, macrolides, and fluoroquinolones.

C. Antibiotics can inhibit bacterial cell wall synthesis, protein synthesis, or DNA replication: This statement reflects the primary mechanisms of action of antibiotics. By targeting these vital bacterial processes, antibiotics effectively prevent bacterial growth or kill the organisms.

D. The mechanism of action of antibiotics involves their chemical structure only: While chemical structure influences how a drug works, the mechanism of action is defined by its specific biological effect on bacteria, not just its molecular makeup.
