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: Difficulty swallowing is a sign of anaphylaxis, which is a severe allergic reaction that can cause swelling of the throat and tongue, leading to airway obstruction and respiratory distress.

Choice B reason: Petechial rash on the abdomen is not a sign of anaphylaxis, but rather a sign of thrombocytopenia, which is a low platelet count that can cause bleeding under the skin.

Choice C reason: Hypertension is not a sign of anaphylaxis, but rather a sign of high blood pressure, which can be caused by various factors such as stress, pain, or kidney disease.

Choice D reason: Bilateral tinnitus is not a sign of anaphylaxis, but rather a sign of hearing loss or damage, which can be caused by exposure to loud noise, ear infection, or medication side effects.

Choice A reason: Providing the client with small-handled adaptive utensils is not necessary for a visually impaired client. The client may prefer to use their own utensils or regular ones that they are familiar with.

Choice B reason: Describing the food placement as though the plate were a clock is a helpful technique to orient the client to their meal and avoid spills or accidents. The nurse should also ask the client about their preferences and needs before serving the food.

Choice C reason: Discouraging conversations during the client's mealtime is not appropriate for a visually impaired client. The nurse should encourage social interactions and respect the client's dignity and autonomy.

Choice D reason: Arranging for an assistive personnel to feed the client is not indicated for a visually impaired client. The nurse should promote the client's independence and self-care abilities as much as possible.
