A nurse is caring for a client who is postoperative following knee arthroplasty and has a new prescription for enoxaparin 1mg/kg subcutaneous. The client weighs 185 lb. How many mg should the nurse administer? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

A. Venous thromboembolism (VTE) - While VTE can cause leg pain and swelling, the presence of fever, chills, and localized trauma history in this scenario points more toward cellulitis.

B. Cellulitis
The client's symptoms, including pain, swelling, fever, chills, and sweating, are indicative of cellulitis, which is a bacterial skin infection. The history of trauma to the leg (hitting the leg on the car door) could have introduced bacteria into the skin, leading to the infection. The client's diabetes mellitus type 2 also increases the risk of developing skin infections due to impaired immune function and circulation. Cellulitis often presents with localized pain, swelling, warmth, redness, and systemic symptoms like fever and chills. Immediate medical evaluation and appropriate antibiotic treatment are necessary for cellulitis.

C. Arterial insufficiency - Arterial insufficiency typically presents with symptoms like intermittent claudication, rest pain, and non-healing wounds due to poor circulation. The symptoms described in the scenario are more consistent with an acute infection (cellulitis) rather than chronic arterial insufficiency.

D. Thrombocytopenia - Thrombocytopenia is a condition characterized by low platelet count and does not directly cause localized pain, swelling, and redness in the leg as described in the scenario.

A. Urine culture and sensitivity
Explanation: A urine culture and sensitivity test involves growing bacteria from a urine sample in a laboratory setting. Once the bacteria have grown, they are exposed to different antibiotics to see which one is most effective in inhibiting their growth. This helps healthcare providers identify the specific strain of bacteria causing the infection and choose the most appropriate antibiotic treatment.

B. Serum creatinine level
Explanation: Serum creatinine level is a blood test used to measure kidney function. It evaluates how well the kidneys are filtering waste from the blood. While important for assessing kidney health, it does not determine the specific bacteria causing a urinary tract infection or the appropriate antibiotic treatment.

C. Urinalysis
Explanation: Urinalysis is a broad screening test that assesses various components in the urine, such as red and white blood cells, protein, glucose, and bacteria. While it can detect signs of a urinary tract infection (such as the presence of bacteria and white blood cells), it does not identify the specific bacterial strain causing the infection or provide information about antibiotic sensitivity.

D. Kidney scan
Explanation: A kidney scan, also known as a renal scan, is a medical imaging technique used to assess the structure and function of the kidneys. It can help diagnose conditions like kidney stones, urinary obstruction, or kidney infections. However, it does not determine the strain of bacteria causing a urinary tract infection or guide antibiotic treatment.
