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. Calcium Oxalate

The most common substance found in the analysis of renal stones is calcium oxalate. Calcium oxalate stones are the most prevalent type of kidney stones, accounting for the majority of cases. These stones can form when there is an excess of calcium or oxalate in the urine, and they can vary in size and shape. Other types of kidney stones include uric acid stones, struvite stones (magnesium-ammonium phosphate), and cystine stones, but calcium oxalate stones are the most common.

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.
