A nurse is preparing to administer enoxaparin 1 mg/kg subcutaneously to a client who weighs 220 lb. Available is enoxaparin 30 mg/0.3 mL. How many mL should the nurse administer? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Let's break down the problem step-by-step: Step 1: Convert the weight from pounds to kilograms. We know that 1 kg is approximately 2.205 pounds. So, to convert 220 pounds to kilograms, we divide by 2.205: 220 lb ÷ 2.205 lb/kg ≈ 100 kg Step 2: Calculate the total dose of enoxaparin in mg. We need to administer 1 mg of enoxaparin per kilogram of body weight. The client weighs 100 kg, so the total dose is: 1 mg/kg × 100 kg = 100 mg Step 3: Determine the volume to administer. We have enoxaparin 30 mg/0.3 mL available. To find the volume needed for 100 mg, we can set up a proportion: (30 mg / 0.3 mL) = (100 mg / x mL) Cross-multiplying, we get: 30x = 30 Solving for x: x = 30 / 30 = 1 mL Therefore, the nurse should administer 1 mL of enoxaparin.
