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 reason: The nurse should contact the provider to clarify the prescription because applying heat to an area with impaired sensation can cause burns or tissue damage. The nurse should also educate the client about the risks of using heat therapy and alternative methods to relieve pain.

Choice B reason: The Semmes Weinstein monofilament test is used to assess the sensation of light touch in clients with peripheral neuropathy. The nurse should perform this test before applying any intervention that could affect the skin integrity, such as heat, cold, or compression.

Choice C reason: Observing the skin 10 min after the start of treatment is not sufficient to prevent complications from heat therapy. The nurse should monitor the skin continuously and check for signs of redness, blisters, or burns.

Choice D reason: Applying the heating pad as prescribed by the provider is not appropriate for a client with diabetic neuropathy of the lower extremities. Heat can increase blood flow and inflammation in the affected area, which can worsen the condition and increase the risk of infection.

Choice A: This is incorrect because applying petroleum jelly to the client's nares can interfere with oxygen delivery and cause skin breakdown. The nurse should use water-soluble lubricant or saline spray to moisten the nares and prevent dryness from oxygen therapy.

Choice B: This is correct because initiating fall precautions can prevent injury and complications for the client who has aspirated pneumonia and hypoxia. The client may have altered mental status, weakness, or dizziness due to hypoxia, infection, or medications. The nurse should use bed alarms, side rails, and assistive devices as needed.

Choice C: This is incorrect because maintaining the client in a supine position can worsen hypoxia and pneumonia by decreasing lung expansion and increasing secretions. The nurse should elevate the head of the bed at least 30 degrees and encourage frequent position changes to improve ventilation and drainage.

Choice D: This is incorrect because implementing contact precautions is not indicated for the client who has aspirated pneumonia and hypoxia. Aspirated pneumonia is caused by inhalation of foreign material into the lungs, not by transmission of microorganisms from person to person. The nurse should use standard precautions and droplet precautions if the client has a cough or sputum production.
