A nurse is caring for a client who has a pulmonary embolism and has a new prescription for enoxaparin 1.5 mg/kg/dose subcutaneously every 12 hours. The client weighs 245 lbs. How many mg should the nurse administer per dose? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Choice A Reason: Infection is a serious complication of burn injuries, but not the priority risk for assessment and intervention. The nurse should monitor the client's wound healing, temperature, white blood cell count, and signs of sepsis, and administer antibiotics as prescribed. However, these measures are secondary to ensuring adequate oxygenation and ventilation.

Choice B Reason: Airway obstruction is the priority risk for assessment and intervention for a client who has burns of the head, neck, and chest. The nurse should assess the client's airway patency, respiratory rate, oxygen saturation, breath sounds, and signs of respiratory distress, such as stridor, wheezes, or cyanosis. The nurse should also provide humidified oxygen, suction secretions, elevate the head of the bed, and prepare for endotracheal intubation if needed. Airway obstruction can occur due to edema, inflammation, or inhalation injury of the upper airway, and can quickly lead to hypoxia, respiratory failure, and death.

Choice C Reason: Paralytic ileus is a potential complication of burn injuries, but not the priority risk for assessment and intervention. The nurse should assess the client's bowel sounds, abdominal distension, nausea, vomiting, and stool output, and administer fluids, electrolytes, and nutritional support as prescribed. However, these measures are secondary to ensuring adequate oxygenation and ventilation.

Choice D Reason: Fluid imbalance is another potential complication of burn injuries, but not the priority risk for assessment and intervention. The nurse should assess the client's fluid status, urine output, vital signs, weight, and serum electrolytes, and administer intravenous fluids as prescribed. However, these measures are secondary to ensuring adequate oxygenation and ventilation.

Choice A Reason: This choice is incorrect because furosemide is a diuretic that helps to reduce fluid retention and edema. It may be used for clients who have heart failure or hypertension, but it does not treat pulmonary embolism.

Choice B Reason: This choice is correct because heparin is an anticoagulant that helps to prevent blood clots from forming or growing larger. It may be used for clients who have pulmonary embolism, which is a blockage of a pulmonary artery by a blood clot that usually originates from a deep vein thrombosis (DVT). Heparin can reduce the risk of complications such as pulmonary infarction or death.

Choice C Reason: This choice is incorrect because dexamethasone is a corticosteroid that helps to reduce inflammation and immune response. It may be used for clients who have allergic reactions, asthma, or autoimmune diseases, but it does not treat pulmonary embolism.

Choice D Reason: This choice is incorrect because epinephrine is a sympathomimetic that helps to stimulate the heart and blood vessels. It may be used for clients who have cardiac arrest, anaphylaxis, or severe asthma, but it does not treat pulmonary embolism.

Choice E Reason: This choice is incorrect because atropine is an anticholinergic that helps to block the effects of acetylcholine on the heart and smooth muscles. It may be used for clients who have bradycardia, atrioventricular block, or organophosphate poisoning, but it does not treat pulmonary embolism.
