Physical examination of the affected regions of the skin is necessary. Individuals with cellulitis are likely to have a reddened region of the skin, swelling as well as intense pain (Brown & Watson, 2022). Brant experiences pain in his right leg, in a reddened region that is swollen. The affected area should be thoroughly checked for any signs of skin disintegration. Variations in temperature in the area should be monitored along with signs of an abscess (Sutherland & Parent, 2017). Brant revealed that he was bit by a mosquito on the reddened area. This being a seemingly severe case, the physician may order complete blood count (CBC) testing. This will help measure blood count levels (Bennett et al., 2020). A CBC will allow the physician to make an accurate early diagnosis of a wide range of medical conditions. The physician may also order a C-reactive protein (CRP) test, which is a blood test for inflammation. This would be a necessity since Brant has broken skin because of a mosquito bite (Sutherland & Parent, 2017). Brant’s case is an event of major systemic disturbance since there is a manifestation of chills and acute disorientation. Priority diagnostic criteria for Brant would include assessing the occurrence of erythematous inflammation in the basal dermis and subcutaneous tissue. Redness, swelling, and pain are all signs of cellulitis (Sutherland & Parent, 2017). Erythema must be present in order to make the diagnosis. The location and nature of broken skin should also be assessed. For cellulitis to be diagnosed, the patient’s skin must be checked for micro-abrasions resulting from insect bites (Brown & Watson, 2022). Lower limbs are commonly affected. Brant’s positioning and movement should be adjusted. To reduce swelling in the areas facing downward, Brant’s feet and arms should be propped up on cushions while he lays on his back (Zariquiey-Esteva & Santa-Candela, 2017). If Brant stands for a long time, speedy blood flow to the heart may be hindered, which could cause low blood pressure. Brant may also need to be placed on his side in the recovery position, particularly whenever he feels nauseated or feels like vomiting. From the assessment, he feels nauseated and weak and has vomited on numerous occasions (Zariquiey-Esteva & Santa-Candela, 2017). This will help avoid low blood pressure. When germs break through the skin, “cytokines” and “neutrophils” are released into the bloodstream to fight them off. This causes cellulitis, which is characterized by redness, warmth, swelling, and pain (Brown & Watson, 2022, para 5). This appears to have been the case for Brant. He was bitten by a mosquito, which broke his skin, allowing bacteria (Streptococcus pyogenes) to penetrate the area. An outbreak of redness and swelling occurred when “cytokines and neutrophils” were drawn to the area of the skin to fight against the bacteria (Brown & Watson, 2022, para 5). The leucocyte count increased to 15. This is outside of the reference range (4.0–11.0). An excessive immune reaction to an acute inflammation and parasite infection is likely to have induced increased leucocyte levels (Agnello et al., 2021). An increase in leucocyte count is a normal response to infection or inflammation in the bone marrow. Venous blood lactate (4) is also above the reference range (1.3). Blood lactate con
