A nurse is preparing to administer heparin 15,000 units every 12 hr subcutaneously to a client who weighs 80 kg. Available is 10,000 units/mL. How many mL should the nurse administer with each dose?

(Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

The correct answer is 1.5 mL. Here is the explanation:

To calculate the amount of mL to administer, the nurse should use the following formula:

mL = (units ordered / units available) x mL available

Plugging in the values from the question, we get:

mL = (15,000 / 10,000) x 1

mL = 1.5 x 1

mL = 1.5

Therefore, the nurse should administer 1.5 mL of heparin with each dose.

Choice A: This is correct because aligning the client's joints with the joints on the frame can ensure proper functioning and comfort of the CPM device. The nurse should adjust the length and width of the device to fit the client's leg and secure it with straps.

Choice B: This is incorrect because padding the CPM device with a thick pillow can interfere with its movement and cause pressure on the leg. The nurse should use only thin padding or no padding at all for the CPM device.

Choice C: This is incorrect because placing the client in high-Fowler's position can cause flexion contractures and impair circulation in the leg. The nurse should place the client in supine or semi-Fowler's position with the leg elevated on pillows.

Choice D: This is incorrect because setting the degree of flexion and extension as tolerated by client can cause excessive pain and damage to the joint. The nurse should set the degree of flexion and extension according to the provider's prescription and gradually increase it as ordered.
