A nurse is preparing to administer enoxaparin 40 mg subcutaneously for prevention of deep vein thrombosis.
Available is enoxaparin 100 mg/mL. How many mL should the nurse administer? (Round the answer to the nearest tenth.
Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["0.4"]
Step 1: Divide the ordered dose by the available strength: 40 mg ÷ 100 mg/mL = 0.4 mL So, the nurse should administer 0.4 mL.

Correct Answer is ["1"]
Explanation
Step 1: Calculate the number of tablets. The available medication is in 37.5 mg tablets, so 75 mg/day ÷ 2 ÷ 37.5 mg/tablet = 1 tablet (rounded to the nearest whole number).
Correct Answer is ["2.8"]
Explanation
Step 1: The client weighs 154 lb. We need to convert this weight into kg because the dose is prescribed in mg/kg. We know that 1 kg = 2.20462 lb.
Step 2: So, 154 lb ÷ 2.20462 = 69.8532 kg (rounded to the nearest hundredth). Step 3: The prescribed dose is 4 mg/kg.
Step 4: So, 4 mg/kg × 69.8532 kg = 279.4128 mg (rounded to the nearest thousandth). Step 5: The available pentamidine is 100 mg/mL for injection.
Step 6: To find out how many mL should the nurse administer, we divide the required dose by the concentration.
Step 7: So, 279.4128 mg ÷ 100 mg/mL = 2.7941 mL (rounded to the nearest thousandth). The nurse should administer 2.8 mL (rounded to the nearest tenth).
