Which of the following are types of infections that can affect the ear? (Select All that Apply.)

Choice A Reason:
Monitoring the client for an elevated temperature is crucial because it can indicate an infection at the pin sites or other complications. Infections are a common risk with halo fixation devices due to the invasive nature of the pins.

Choice B Reason:
Ensuring the halo jacket is snug against the client's skin is incorrect. The halo jacket should fit properly but not be too tight, as this can cause skin breakdown and discomfort. There should be enough space to insert a flat hand between the vest and the skin.

Choice C Reason:
Providing range of motion to the client's neck is not appropriate for a client with a halo fixation device. The purpose of the halo is to immobilize the neck to allow for proper healing of cervical injuries. Any movement could jeopardize the stability of the injury.

Choice D Reason:
Removing the vest daily to inspect the client's skin integrity is incorrect. The halo vest should not be removed frequently as it is meant to provide continuous immobilization. Skin integrity can be monitored by checking the areas around the vest without removing it.

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.
