An occupational health nurse at a group of health care clinics is planning activities to prevent and control the spread of communicable disease. The nurse should identify that which of the following activities is a secondary level of prevention?

A. Povidone-iodine may be used as a wound cleanser, but the method described here (using cotton balls) is not typically recommended as it can leave fibers in the wound.

B. Administering oral analgesia prior to wound irrigation may be appropriate for pain management but is not directly related to understanding wound irrigation technique.

C. Warming irrigation solution in a microwave oven can lead to uneven heating and potential tissue damage. This method is not recommended for warming irrigation solution.

D. Irrigating the wound from the top to the bottom ensures that contaminants are flushed away from the wound site, reducing the risk of infection and promoting healing. This indicates an understanding of proper wound irrigation technique.

A. Metoprolol is a beta-blocker used to treat hypertension and other cardiovascular conditions.

While it may be important for the provider to be aware of all medications, it is not the priority to report in this scenario.

B. Clopidogrel is an antiplatelet medication used to prevent blood clots in individuals at risk for cardiovascular events. While it may have implications for the procedure, it is not the priority to report in this scenario.

C. Metformin is an oral antidiabetic medication commonly used to treat type 2 diabetes. It is

important to report because there may be specific considerations regarding its use in the context of a colonoscopy, such as the risk of lactic acidosis.

D. Digoxin is a medication used to treat heart failure and certain arrhythmias. While it may have implications for the procedure, it is not the priority to report in this scenario.
