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 sequence the nurse should use to administer the medication using the Z-track technique is:

- Step 1: Put on gloves and cleanse the site with an antiseptic swab.

- Step 2: Use the nondominant hand to pull the skin and subcutaneous tissue 2.5 cm (1 in) laterally.

- Step 3: Insert the needle into the muscle.

- Step 4: Aspirate by pulling back on the plunger and inject the medication.

- Step 5: Remove the needle and release the tissue.

Choice a: Placing the client in high-Fowler's position is the first action that the nurse should take because it can improve lung expansion and oxygenation, which are priority needs for a client who has a pulmonary embolism and is experiencing dyspnea.

Choice b is not correct because administering heparin to the client is not the first action that the nurse should take, but rather a subsequent action after ensuring adequate oxygenation. Heparin can prevent further clot formation and reduce the risk of complications, but it does not dissolve existing clots or improve respiratory status.

Choice c is not correct because encouraging the client to cough and deep breathe is not the first action that the nurse should take, but rather an ongoing intervention that can help mobilize secretions and prevent atelectasis. However, it may not be effective or feasible for a client who has severe dyspnea.

Choice d is not correct because obtaining the client's vital signs is not the first action that the nurse should take, but rather an assessment that can provide baseline data and monitor changes in condition. However, it does not address the immediate problem of impaired gas exchange or relieve dyspnea.
