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 A
Explanation
Choice A Reason: Packed RBCs are indicated for clients who have hypovolemic shock due to blood loss, as they increase the oxygen-carrying capacity of the blood and restore the blood volume.
Choice B Reason: Cryoprecipitates are indicated for clients who have hemophilia or von Willebrand disease, as they contain clotting factors that help stop bleeding.
Choice C Reason: Albumin is indicated for clients who have hypovolemic shock due to fluid loss, such as from burns or ascites, as it increases the plasma oncotic pressure and draws fluid into the vascular space.
Choice D Reason: Platelets are indicated for clients who have thrombocytopenia or platelet dysfunction, as they help prevent or control bleeding.
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
