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: Cause of the burn is not the nurse's priority when assessing the severity of the client's burns. The cause of the burn may indicate the type and duration of exposure, such as thermal, chemical, electrical, or radiation, which can affect the depth and extent of injury. However, these factors are secondary to ensuring adequate oxygenation and ventilation.

Choice B Reason: Age of the client is not the nurse's priority when assessing the severity of the client's burns. The age of the client may influence the response to burn injury, such as healing time, infection risk, and fluid requirements.

However, these factors are secondary to ensuring adequate oxygenation and ventilation.

Choice C Reason: Associated medical history is not the nurse's priority when assessing the severity of the client's burns. The associated medical history may affect the outcome and prognosis of burn injury, such as pre-existing conditions, medications, or allergies. However, these factors are secondary to ensuring adequate oxygenation and ventilation.

Choice D Reason: Location of the burn is the nurse's priority when assessing the severity of the client's burns. The location of the burn can indicate the potential for life-threatening complications, such as airway obstruction, inhalation injury, or impaired circulation. The nurse should assess for signs and symptoms of respiratory distress, such as stridor, wheezes, or cyanosis, and prepare for endotracheal intubation if needed. The nurse should also monitor for signs and symptoms of compartment syndrome, such as pain, pallor, paresthesia, pulselessness, or paralysis, and report any findings to the provider. The location of the burn can also affect the functional and cosmetic outcomes, such as vision loss, facial disfigurement, or joint contractures. The nurse should provide appropriate wound care, pain management, and rehabilitation as prescribed. Assessing for location of burn is essential to prevent further injury and preserve vital functions.

Choice A Reason: Dobutamine is a positive inotropic agent that increases the contractility of the heart and improves cardiac output. This leads to increased renal perfusion and urine output, which reduces the fluid overload and edema associated with heart failure. Therefore, this choice is correct.

Choice B Reason: Dobutamine does not have a direct effect on blood glucose level. It may cause hyperglycemia as a side effect, but this is not an indication of its effectiveness. Therefore, this choice is incorrect.

Choice C Reason: Dobutamine may cause a slight decrease in blood pressure due to vasodilation, but this is not its main therapeutic effect. A significant decrease in blood pressure may indicate hypovolemia, hypotension, or shock, which are adverse effects of dobutamine. Therefore, this choice is incorrect.

Choice D Reason: Dobutamine also has a positive chronotropic effect, which means it increases the heart rate. However, this is not a desired outcome for a client with heart failure, as it increases the oxygen demand of the heart and may worsen the condition. Therefore, this choice is incorrect.
