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 ["24"]
Explanation
- To find the concentration of heparin in the solution, divide the amount of heparin by the volume of D5W: 25,000 units / 500 mL = 50 units/mL
- To find the infusion rate, divide the prescribed dose by the concentration: 1,200 units/hr / 50 units/mL = 24 mL/hr
- Round the answer to the nearest tenth/whole number: 24 mL/hr
Correct Answer is D
Explanation
Choice A Reason: This is incorrect because respiratory alkalosis is characterized by a high pH and a low PaCO2, indicating that the client is hyperventilating and losing too much carbon dioxide.
Choice B Reason: This is incorrect because metabolic acidosis is characterized by a low pH and a low bicarbonate level, indicating that the client has an excess of metabolic acids or a loss of base.
Choice C Reason: This is incorrect because metabolic alkalosis is characterized by a high pH and a high bicarbonate level, indicating that the client has an excess of base or a loss of metabolic acids.
Choice D Reason: This is correct because respiratory acidosis is characterized by a low pH and a high PaCO2, indicating that the client is hypoventilating and retaining too much carbon dioxide.
