Final answer:
Sterile wound irrigation helps reduce bacterial counts and may be delegated to experienced nursing assistive personnel. Antiseptics are suitable for microbial control on tissues to prevent infection. Long-term use of broad-spectrum antimicrobials can lead to superinfections.
Step-by-step explanation:
Regarding sterile wound irrigation, the statements that are true include that it is useful for decreasing bacterial counts in a wound (sterile wound irrigation) and that these procedures may be delegated to experienced nursing assistive personnel (NAP), provided they have been properly trained and the task fits within their scope of responsibilities. Therefore, the correct option would be C. Both A and B.
For antimicrobial control to prevent infection on tissues, the substance that is suitable is an antiseptic (Option B). Antiseptics are antimicrobial substances that are applied to living tissue/skin to reduce the possibility of infection, sepsis, or putrefaction.
Long-term use of broad-spectrum antimicrobials is most likely to contribute to the development of a superinfection (Option B). Broad-spectrum antimicrobials kill a wide range of bacteria, including both harmful and beneficial microbes, which can disturb the balance and lead to overgrowth of resistant organisms.
