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: Preventing musculoskeletal disability is important, but not the priority focus of care. The nurse should first assess and manage the client's life-threatening injuries, such as airway obstruction, bleeding, shock, or brain injury.

Choice B Reason: Airway protection is the priority focus of care for a client with multiple system trauma. The nurse should ensure that the client has a patent airway and adequate ventilation, as any compromise in these areas can quickly lead to hypoxia, respiratory failure, and death.

Choice C Reason: Stabilizing cardiac arrhythmias is also important, but not the priority focus of care. The nurse should monitor the client's cardiac rhythm and treat any arrhythmias that may occur, but only after securing the airway and breathing.

Choice D Reason: Decreasing intracranial pressure is another important goal, but not the priority focus of care. The nurse should assess the client's neurological status and intervene to prevent or reduce increased intracranial pressure, such as elevating the head of the bed, maintaining normothermia, and administering osmotic diuretics. However, these measures are secondary to ensuring adequate oxygenation and perfusion.

Choice A Reason: This is incorrect because crepitus in the area above and surrounding the insertion site is not a serious finding that requires notification of the provider. Crepitus is a crackling sensation that occurs when air leaks into the subcutaneous tissue. It is usually harmless and resolves on its own.

Choice B reason: This is incorrect because bubbling of the water in the water seal chamber with exhalation is a normal finding that indicates that air is being removed from the pleural space. Bubbling should stop when the pneumothorax is resolved.

Choice C Reason: This is incorrect because eyelets are not visible is not a serious finding that requires notification of the provider. Eyelets are small holes at the end of the chest tube that allow air and fluid to drain from the pleural space. They are usually covered by a dressing and may not be visible.

Choice D Reason: This is correct because movement of the trachea toward the unaffected side is a serious finding that indicates a tension pneumothorax, which is a life-threatening condition that occurs when air accumulates in the pleural space and causes pressure on the mediastinum. The nurse should notify the provider immediately and prepare for needle decompression or chest tube insertion.
