Correct Answer is ["A","B","C"]

Explanation

A. A Venturi mask is an accurate way to deliver a specific concentration of oxygen, allowing for precise control.
B. Humidifying oxygen is recommended at flow rates higher than 4 liters per minute to prevent drying of the mucous membranes.
C. Oxygen toxicity can occur if high concentrations of oxygen are administered for prolonged periods, leading to potential lung damage.
D. Nasal cannulas typically provide a lower oxygen concentration than higher-flow devices, like a Venturi mask or non-rebreather mask.
E. Oxygen therapy is not always entirely safe regardless of the patient's condition; certain conditions require careful monitoring to prevent complications.

A. Assume the episode was a migraine and schedule a neurology follow-up for a later date. B. Discharge the patient immediately since the symptoms resolved. C. Initiate antiplatelet therapy, such as aspirin, to reduce the risk of future strokes. D. Order a CT scan of the head to rule out intracranial hemorrhage. E. Start anticoagulation therapy immediately without further evaluation. F. Conduct a carotid ultrasound to assess for stenosis. G. Refer the patient for lifestyle modifications, including smoking cessation and diet changes.

Correct Answer is ["C","D","F","G"]

Explanation

A. Assuming the episode was a migraine and scheduling a follow-up is not appropriate. TIAs are serious warning signs of potential future strokes and require immediate attention and evaluation.
B. Discharging the patient immediately after symptoms resolve is not appropriate. Even though symptoms resolve, TIAs are medical emergencies, and further evaluation is necessary to reduce the risk of a full-blown stroke.
C. Initiating antiplatelet therapy, such as aspirin, is an appropriate action to reduce the risk of future strokes in patients who have had a TIA.
D. Ordering a CT scan of the head is appropriate to rule out an intracranial hemorrhage and other causes of the symptoms.

E. Starting anticoagulation therapy immediately without further evaluation is not recommended. The patient must be properly assessed before starting anticoagulation to determine the cause of the TIA and if anticoagulation is appropriate.
F. Conducting a carotid ultrasound is appropriate to assess for stenosis, which could be contributing to the TIA.
G. Referring the patient for lifestyle modifications, including smoking cessation and diet changes, is crucial to reduce future stroke risk. These interventions help prevent the recurrence of TIAs and strokes.
