A nurse is caring for a client who has a head injury. The client states they fell off a ladder while painting approximately 2 hours ago and lost consciousness for 45 minutes according to their partner. The nurse should determine that the client is experiencing which of the following classifications of traumatic brain injury?

The correct answer is A. Moderate.

Choice A: Moderate

A moderate traumatic brain injury (TBI) is characterized by a loss of consciousness (LOC) lasting between 30 minutes and 6 hours. In this scenario, the client lost consciousness for 45 minutes, which falls within this range. Moderate TBIs often result in more significant symptoms and may require more intensive medical intervention compared to mild TBIs.

Choice B: Severe

Severe TBIs are typically defined by a loss of consciousness lasting more than 6 hours. Since the client in this case was unconscious for only 45 minutes, this classification does not apply. Severe TBIs often involve extensive brain damage and can lead to long-term complications or disabilities.

Choice C: Mild

Mild TBIs, also known as concussions, are characterized by a loss of consciousness lasting less than 30 minutes. Given that the client was unconscious for 45 minutes, this classification is not appropriate. Mild TBIs usually result in temporary symptoms that resolve with minimal medical intervention.

Choice D: No traumatic brain injury

This option is incorrect because the client experienced a significant head injury with a loss of consciousness for 45 minutes. Such an event clearly indicates a traumatic brain injury, and it is essential to classify it correctly to ensure appropriate medical care.

Choice A reason: Positioning the head of the client’s bed in the flat position is not a good way to reduce the risk of ventilator associated pneumonia. This position can increase the risk of aspiration of oral secretions or gastric contents into the lungs, which can cause infection. The nurse should elevate the head of the bed to 30 to 45 degrees to prevent aspiration and promote drainage of secretions.

Choice B reason: Brushing the client’s teeth with a suction toothbrush every 12 hr is an effective way to reduce the risk of ventilator associated pneumonia. Oral hygiene can reduce the number of bacteria in the mouth and prevent the formation of dental plaque, which can harbor pathogens that can cause pneumonia. The nurse should use a suction toothbrush to remove debris and secretions from the mouth and prevent them from entering the lungs.

Choice C reason: Providing humidity by maintaining moisture within the ventilator tubing is not a helpful way to reduce the risk of ventilator associated pneumonia. Humidity can increase the growth of bacteria and fungi in the ventilator circuit, which can contaminate the air delivered to the lungs. The nurse should change the ventilator tubing and filters regularly and use sterile water to fill the humidifier.

Choice D reason: Turning the client every 4 hr is not a sufficient way to reduce the risk of ventilator associated pneumonia. Turning can help prevent pressure ulcers and improve blood circulation, but it does not prevent the accumulation of secretions in the lungs, which can cause infection. The nurse should use chest physiotherapy, suctioning, and coughing techniques to mobilize and clear secretions from the airways.
