A nurse is reviewing oxygen therapy with a group of new graduates. Which of the following statements indicate a correct understanding of oxygen therapy?
(Select All that Apply.)
A Venturi mask allows for precise oxygen concentration delivery.
Oxygen should be humidified when delivered at flow rates higher than 4 liters per minute.
Oxygen toxicity can occur when high concentrations of oxygen are administered for extended periods.
Nasal cannulas can deliver oxygen concentrations up to 90%.
Oxygen therapy is always safe regardless of the patient's condition.
A simple face mask can deliver higher oxygen concentrations than a non-rebreather mask.
Correct Answer : A,B,C
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.

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.
Correct Answer is ["320"]
Explanation
Net fluid balance = Total intake - Total output
Rationale:
Total intake:
IV fluids: 1,000 mL
Antibiotic infusion: 250 mL
Oral intake: 3 cups x 240 mL = 720 mL
Total intake = 1,000 + 250 + 720 = 1,970 mL Total output:
Urine: 1,200 mL
Vomiting: 300 mL Wound drainage: 150 mL
Total output = 1,200 + 300 + 150 = 1,650 mL
Net fluid balance = 1,970 mL - 1,650 mL = +320 mL
The patient has a positive fluid balance of 320 mL.
