While changing the dressing of a client who is immobile, the practical nurse (PN) observes a red and swollen wound with a moderate amount of yellow and green drainage and a foul odor. Before reporting this finding to the healthcare provider, the PN should evaluate which of the client's laboratory values?

The correct answer is choice B. Culture for sensitive organisms. Choice A rationale: C-reactive protein (CRP) levels are indicative of inflammation in the body and can help identify the presence of an infection. However, CRP levels do not provide specific information about the type of organism causing the infection, which is crucial for targeted treatment. Choice B rationale: A culture for sensitive organisms is essential in this scenario because it identifies the specific bacteria or other pathogens present in the wound. This information is critical for selecting the appropriate antibiotic therapy to treat the infection effectively. Choice C rationale: Serum albumin levels are important for assessing nutritional status and overall health, which can impact wound healing. Low albumin levels can indicate poor nutritional status and delayed wound healing, but they do not provide immediate information about the infection itself. Choice D rationale: Serum blood glucose (BG) levels are crucial for managing diabetes and can affect wound healing. High blood glucose levels can impair the immune response and slow down the healing process. However, like CRP, BG levels do not provide specific information about the type of infection present in the wound.
