The physician orders a Lidocaine drip to infuse at 5 mcg/min. The drug is available as 750 mg in 500 mL of fluid. The client weighs 220 pounds. Calculate mcg/min, mcg/hr, and mL/hr.

Choice A Reason:
Narrowing pulse pressure is not typically associated with contusions from a motor-vehicle crash. It is more commonly seen in conditions like cardiac tamponade or severe blood loss. While it can indicate a serious condition, it is not a direct result of a contusion.

Choice B Reason:
Drainage of clear fluid from the ears, known as otorrhea, can indicate a basilar skull fracture rather than a simple contusion. This finding suggests cerebrospinal fluid leakage, which is a serious complication requiring immediate medical attention.

Choice C Reason:
Periods of unconsciousness and/or confusion are expected findings in clients with contusions, especially if the brain is involved. These symptoms indicate a concussion or more severe brain injury, which can result from the impact of a motor-vehicle crash.

Choice D Reason:
Extensive bruising in the mastoid area, known as Battle's sign, is indicative of a basilar skull fracture rather than a contusion. This type of bruising appears behind the ear and is a sign of a more severe head injury.

Choice A Reason:
Consuming a diet high in vitamin K to promote clotting is not typically recommended for patients with DIC. While vitamin K is essential for clotting, DIC involves both excessive clotting and bleeding. Increasing vitamin K intake could exacerbate clotting issues without addressing the underlying imbalance.

Choice B Reason:
Stopping all medications to prevent interactions with clotting factors is not advisable. Patients with DIC often require medications to manage their condition, including anticoagulants and treatments for the underlying cause. Discontinuing all medications could lead to uncontrolled symptoms and complications.

Choice C Reason:
Engaging in physical activity to promote blood flow is generally beneficial for overall health, but in the context of DIC, it must be approached with caution. Physical activity can increase the risk of injury and bleeding, which is a significant concern for patients with DIC. Therefore, any exercise regimen should be carefully monitored and tailored to the patient's condition.

Choice D Reason:
Avoiding activities that may cause injury or bleeding is crucial for patients with DIC. Due to the risk of spontaneous bleeding and the potential for minor injuries to lead to significant blood loss, patients must take precautions to minimize these risks. This includes avoiding contact sports, using soft-bristled toothbrushes, and being cautious with sharp objects.
