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.)

Choice A: This is incorrect. The nurse should don clean gloves before removing the dressing, and then change to sterile gloves before applying the new dressing.

Choice B: This is correct. The nurse should offer the client pain medication before the procedure, as changing a dressing for a stage III pressure ulcer can be very painful.

Choice C: This is incorrect. The nurse should prepare the sterile dressing supplies just before the dressing change, not 30 min before, to prevent contamination.

Choice D: This is incorrect. The nurse should not disinfect the wound bed with alcohol, as this can damage the healthy tissue and delay healing. The nurse should use a saline solution or an antiseptic solution as prescribed.

Choice A reason: Glucocorticoids are anti-inflammatory drugs that can increase blood glucose levels and worsen diabetes mellitus, which is a risk factor for stroke.

Choice B reason: HbA1c is a measure of average blood glucose levels over the past three months. A higher HbA1c level indicates poor glycemic control and increases the risk for stroke. The target HbA1c level for most people with diabetes mellitus is less than 7 percent.

Choice C reason: Having a high total cholesterol level is a risk factor for stroke, as it can lead to atherosclerosis and plaque formation in the blood vessels. The target total cholesterol level for most people is less than 200 mg/dL.

Choice D reason: Losing excess weight can lower blood pressure, improve blood glucose levels, and reduce inflammation, which are all beneficial for preventing stroke.
