Client Safety Alternatives to Restraints Quizlet Questions
Question 1 of 5
Within how many feet of oxygen administration is smoking not allowed?
Correct Answer: B
Rationale: The correct answer is B: 12 feet. This distance is established to prevent fires as oxygen supports combustion. Smoking within 12 feet of oxygen administration poses a significant fire hazard. Choice A (4 meters) is incorrect as it is greater than 12 feet. Choices C and D are incorrect as they do not provide a specific distance requirement.
Question 2 of 5
Maintenance of fluid balance in the patient with ARDS involves
Correct Answer: C
Rationale: Step-by-step rationale for choice C being correct: 1. ARDS patients have increased capillary permeability leading to fluid leakage into the lungs. 2. Mild fluid restriction helps prevent fluid overload and pulmonary edema. 3. Diuretics help manage any excess fluid accumulation. 4. Hydration using colloids (choice A) can exacerbate fluid overload. 5. Surfactant (choice B) is used in neonatal respiratory distress syndrome, not ARDS. 6. Keeping hemoglobin level >12 g/dL (choice D) is unrelated to fluid balance in ARDS.
Question 3 of 5
After prolonged cardiopulmonary bypass, a patient develops increasing shortness of breath and hypoxemia. To determine whether the patient has acute respiratory distress syndrome (ARDS) or pulmonary edema caused by left ventricular failure, the nurse will anticipate assisting with
Correct Answer: D
Rationale: The correct answer is D, inserting a pulmonary artery catheter. This is the most appropriate action to differentiate between ARDS and pulmonary edema caused by left ventricular failure. The pulmonary artery catheter can provide valuable information such as pulmonary artery pressure, pulmonary capillary wedge pressure, and cardiac output. In ARDS, the pulmonary artery pressure and pulmonary capillary wedge pressure are typically low, whereas in pulmonary edema due to left ventricular failure, these pressures are elevated. Positioning the patient for a chest radiograph (A) would provide anatomical information but not differentiate between ARDS and pulmonary edema. Drawing blood for arterial blood gases (B) can provide information on oxygenation but may not be sufficient to differentiate between the two conditions. Obtaining a ventilation-perfusion scan (C) is not typically used to differentiate between ARDS and pulmonary edema.
Question 4 of 5
the environment is warm
Correct Answer: A
Rationale: The correct answer is A because in a warm environment, the body needs to cool itself to maintain a stable internal temperature. This process is called thermoregulation. Sweating and vasodilation are mechanisms the body uses to release heat and cool down. Choice B is incorrect as the body does not need to warm itself in a warm environment. Choices C and D are incomplete and do not offer a logical explanation related to the situation given.
Question 5 of 5
A patient with ARDS is being mechanically ventilated. The physician has ordered prone positioning. What is the primary reason for this intervention?
Correct Answer: D
Rationale: The correct answer is D. Prone positioning helps recruit collapsed alveoli by redistributing ventilation to dependent lung regions, improving oxygenation in ARDS. It enhances lung homogeneity and reduces stress on the dorsal lung regions. Choices A, B, and C are incorrect because prone positioning primarily aims to optimize oxygenation by improving lung ventilation and perfusion, rather than solely reducing diaphragm workload, enhancing perfusion to anterior lung segments, or mobilizing secretions.
