What condition does the nurse suspect when a patient involved in a motor vehicle accident arrives at the emergency department with ecchymosis behind the ears and bleeding from the ears?

Epidural hematoma.

Ischemic stroke.

Subarachnoid hemorrhage.

Basilar skull fracture.

Answer and Explanation

The Correct Answer is D

Choice A reason: An epidural hematoma is a type of traumatic brain injury where blood accumulates between the dura mater and the skull. While it can cause severe symptoms, including headache, loss of consciousness, and neurological deficits, it does not typically present with ecchymosis behind the ears (Battle's sign) or bleeding from the ears. These signs are more indicative of a basilar skull fracture.

Choice B reason: An ischemic stroke occurs when a blood clot blocks or narrows an artery leading to the brain, causing reduced blood flow and oxygen to the brain tissue. Symptoms of an ischemic stroke include sudden weakness, numbness, difficulty speaking, and vision problems. However, it does not cause ecchymosis behind the ears or bleeding from the ears, which are specific signs of a basilar skull fracture.

Choice C reason: A subarachnoid hemorrhage is bleeding into the space between the brain and the tissue covering the brain (subarachnoid space). It often presents with a sudden, severe headache, nausea, vomiting, and loss of consciousness. While it is a serious condition, it does not typically cause ecchymosis behind the ears or bleeding from the ears.

Choice D reason: A basilar skull fracture is

The correct answer. This type of fracture involves the base of the skull and can cause characteristic signs such as ecchymosis behind the ears (Battle's sign) and bleeding from the ears due to the proximity of the fracture to the auditory canal and other structures. These symptoms are key indicators of a basilar skull fracture and require immediate medical attention.

Correct Answer is A

Explanation

Choice A reason: Keeping the head of the bed elevated at least 30 degrees is crucial in preventing ventilator-associated pneumonia (VAP). Elevating the head of the bed reduces the risk of aspiration of gastric contents and oral secretions into the lungs, which can lead to infection. This positioning helps improve lung expansion and facilitates drainage, thereby decreasing the likelihood of VAP.

Choice B reason: Administering ordered antibiotics as scheduled is important for treating existing infections but is not a primary preventive measure for ventilator-associated pneumonia. While antibiotics play a role in managing infections, the focus here is on preventive strategies. Overreliance on antibiotics can also lead to antibiotic resistance, making infection control more challenging.

Choice C reason: Hyperoxygenating the patient before suctioning is a standard practice to prevent hypoxia during the procedure, but it is not directly related to preventing ventilator-associated pneumonia. While hyperoxygenation helps maintain adequate oxygen levels, it does not address the specific risk factors associated with the development of VAP.

Choice D reason: Suctioning the airway every 2 hours may be necessary for some patients to maintain airway patency and remove secretions. However, routine suctioning at fixed intervals is not always appropriate and can increase the risk of trauma to the airway and infection. Suctioning should be performed based on clinical assessment and the patient's needs rather than a fixed schedule to prevent complications and potential infections.

A. Arterial Blood Gas (ABG). B. Blood pressure. C. Heart rate. D. Capillary refill.

Correct Answer is A

Explanation

Choice A reason: Arterial Blood Gas (ABG) analysis is the best method to determine the effectiveness of treatments for a client in acute respiratory failure who is receiving mechanical ventilation. ABG provides essential information about the patient's oxygenation status, carbon dioxide levels, and acid-base balance. It allows healthcare providers to assess how well the lungs are oxygenating the blood and removing carbon dioxide. By analyzing the ABG results, the effectiveness of the mechanical ventilation and any necessary adjustments can be made to improve the client's respiratory status.

Choice B reason: Blood pressure monitoring is important for evaluating the overall cardiovascular status of a patient but is not the most specific assessment for determining the effectiveness of treatments in acute respiratory failure. While blood pressure can provide indirect information about cardiac output and perfusion, it does not directly reflect the patient's oxygenation and ventilation status, which are critical in the context of respiratory failure.

Choice C reason: Heart rate monitoring is useful for assessing the patient's hemodynamic status and detecting potential arrhythmias or other cardiac issues. However, it does not provide specific information about the effectiveness of treatments for acute respiratory failure. Heart rate alone cannot indicate how well the lungs are functioning or how effectively mechanical ventilation is supporting the patient's respiratory needs.

Choice D reason: Capillary refill is a simple and quick assessment of peripheral perfusion, indicating how well the blood is flowing to the extremities. While it can provide some information about the patient's circulatory status, it is not a reliable method for determining the effectiveness of treatments in acute respiratory failure. Capillary refill does not provide direct information about oxygenation, ventilation, or the overall respiratory status of the patient.
