A nurse is assessing a patient who has acute respiratory distress syndrome (ARDS). Which of the following findings should the nurse expect?
Impaired carbon dioxide elimination due to shunting.
Decreased pulmonary arterial pressure due to ventilation-perfusion (V/Q) mismatch.
Hypoxemia due to dead space.
Decreased pulmonary compliance due to stiffness.
Correct Answer : A,D
Choice A rationale
In ARDS, impaired carbon dioxide elimination due to shunting can occur. Shunting refers to the diversion of blood from areas of the lung that are ventilated to areas that are not, leading to impaired gas exchange.
Choice B rationale
Decreased pulmonary arterial pressure due to ventilation-perfusion (V/Q) mismatch is not a typical finding in ARDS3.
Choice C rationale
Hypoxemia due to dead space is not a typical finding in ARDS. Dead space refers to areas of the lung that are ventilated but not perfused.
Choice D rationale
Decreased pulmonary compliance due to stiffness is a typical finding in ARDS. The lungs become stiff and less compliant due to the accumulation of fluid and inflammatory cells in the alveoli and interstitial space.

Correct Answer is C
Explanation
Choice A rationale
Performing passive range of motion exercises on the right leg in Buck’s traction may not be appropriate. These exercises involve moving the joint without the patient’s muscles doing the work, which could disrupt the traction.
Choice B rationale
Isometric exercises involve contracting the muscles without moving the joints. While these exercises can be beneficial for maintaining muscle strength, they may not promote mobility.
Choice C rationale
Performing active range-of-motion exercises on the left leg can help promote mobility. These exercises involve the patient moving the joint through its full range of motion, which can help maintain joint flexibility and muscle strength.
Choice D rationale
Log rolling the patient every 2 hours may not be appropriate for a patient in Buck’s traction. This technique involves turning the patient as a unit to prevent twisting and protect the spine, which could disrupt the traction.
Correct Answer is D
Explanation
Choice A rationale
Avoiding warm water to wash the patient’s face is not typically necessary for a patient with a right-sided acoustic neuroma.
Choice B rationale
Applying an eye patch to the patient’s right eye is not typically necessary unless the patient is experiencing double vision, which is not a common symptom of acoustic neuroma.
Choice C rationale
Providing range-of-motion exercises to the patient’s neck and shoulders is not typically necessary for a patient with a right-sided acoustic neuroma.
Choice D rationale
Placing suction equipment at the patient’s bedside can be helpful if the patient is experiencing difficulty swallowing or has a risk of aspiration due to impairment of cranial nerves IX and X111213.
