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.)
The Correct Answer is ["167 "]
To calculate the dose of enoxaparin, follow these steps:
1) Convert the client's weight from pounds to kilograms:
245 lbs / 2.2046 (kg/lb) = 111.13 kg (rounded to the nearest whole number, it's 111 kg).
2) Multiply the weight in kilograms by the prescribed dose per kilogram:
111 kg x 1.5 mg/kg = 166.5 mg.
Round the answer to the nearest whole number, so the nurse should administer 167 mg per dose of enoxaparin every 12 hours to the client with a pulmonary embolism.

Correct Answer is B
Explanation
Choice A Reason: Equal amount of fluid drainage in each collection chamber is not a sign of proper chest tube function. The amount of fluid drainage depends on the type and extent of the client's injury or surgery, and may vary from one chamber to another.
Choice B Reason:Fluctuation of the fluid level in the water seal chamber(tidaling) indicates that the chest tube is functioning properly. This fluctuation corresponds with the client's respirations and shows that air or fluid is being effectively removed from the pleural space.
Choice C Reason:Continuous bubbling within the water seal chamber: Continuous bubbling in the water seal chamber indicates an air leak, which is not normal unless the client has a pneumothorax and air is being evacuated. Otherwise, it suggests a problem with the system.
Choice D Reason: Absence of fluid in the drainage tubing is not a sign of proper chest tube function. It may indicate that the chest tube is obstructed, kinked, or clamped, or that the suction is not working properly. The nurse should assess and troubleshoot the chest tube system.
Correct Answer is B
Explanation
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.
