A nurse is caring for a client who has a pulmonary embolism and has a new prescription for enoxaparin 1.5 mg/kg/dose subcutaneously every 12 hours. The client weighs 245 lbs. How many mg should the nurse administer per dose? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["167 "]
To calculate the dose of enoxaparin, follow these steps:
1) Convert the client's weight from pounds to kilograms:
245 lbs / 2.2046 (kg/lb) = 111.13 kg (rounded to the nearest whole number, it's 111 kg).
2) Multiply the weight in kilograms by the prescribed dose per kilogram:
111 kg x 1.5 mg/kg = 166.5 mg.
Round the answer to the nearest whole number, so the nurse should administer 167 mg per dose of enoxaparin every 12 hours to the client with a pulmonary embolism.

Correct Answer is C
Explanation
Choice A Reason: This is incorrect because a client who is post-CABG and has high cholesterol is not in immediate danger, as atorvastatin is a long-term medication that lowers cholesterol and prevents cardiovascular complications.
Choice B Reason: This is incorrect because a client who has pneumonia and a slightly elevated WBC count is not in immediate danger, as piperacillin is an antibiotic that treats bacterial infections.
Choice C Reason: This is correct because a client who has renal failure and a high serum potassium level is in immediate danger, as sodium polystyrene sulfonate is an emergency medication that lowers potassium and prevents cardiac arrhythmias.
Choice D Reason: This is incorrect because a client who has anemia and a mild hemoglobin deficiency is not in immediate danger, as epoetin alfa is a long-term medication that stimulates red blood cell production and improves oxygen delivery.
Correct Answer is ["125"]
Explanation
Step 1: Determine the total time required to infuse 40 mEq at a rate of 10 mEq/hr.
40 mEq ÷ 10 mEq/hr = 4 hours
Result: 4 hours
Step 2: Determine the infusion rate in mL/hr.
500 mL ÷ 4 hours = 125 mL/hr
Result: 125 mL/hr
The nurse should set the IV pump to deliver 125 mL/hr.
