Which of the following is an example of a reservoir in the chain of infection?

A. Avoiding use of a urinary catheter: While avoiding unnecessary urinary catheterization is important to prevent healthcare-associated urinary tract infections, this action may not be directly applicable to an incontinent patient who requires interventions to manage incontinence.
B. Applying absorbent briefs: Using absorbent briefs helps contain urine and feces, reducing the risk of skin breakdown and contamination of the environment.
C. Restricting Fluids: Restricting fluids may lead to dehydration and is not a recommended approach for preventing healthcare-associated infections in incontinent patients.
D. Toileting patient every 4 hours: Toileting frequency should be individualized based on the patient's needs and not restricted to a specific time interval. Additionally, simply toileting the patient may not be sufficient to prevent healthcare-associated infections if proper hygiene practices are not followed.

A. Swelling, tenderness, and purulent drainage around the wound are classic signs of a wound infection. Swelling and tenderness indicate inflammation, while purulent drainage (pus) suggests the presence of infection.
B. Urticaria and itching around the wound are more indicative of an allergic reaction or hypersensitivity rather than a wound infection.
C. Serosanguineous drainage (clear to blood-tinged fluid) is a normal finding in the early stages of wound healing and does not necessarily indicate infection.
D. Brown crusting over the wound may indicate the formation of an eschar, which can occur in wounds undergoing healing, particularly in wounds with necrotic tissue. It is not necessarily indicative of infection unless accompanied by other signs such as erythema, warmth, or purulent drainage.
