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 A
Explanation
Choice A rationale
Nausea and vomiting are common symptoms associated with migraines. Asking about these symptoms can help in assessing the severity of the migraine and planning appropriate interventions.
Choice B rationale
Sensitivity to light, also known as photophobia, is a common symptom of migraines. However, the presence of this symptom alone may not provide a comprehensive understanding of the patient’s condition.
Choice C rationale
While confusion or clouded thinking can occur with migraines, they are not as common as other symptoms such as nausea, vomiting, and sensitivity to light.
Choice D rationale
Feeling weak before the headache starts or currently feeling weak can be associated with migraines, but they are not the most common symptoms.
Correct Answer is C
Explanation
Choice A rationale
Lifting a patient under the shoulders by two nurses can be strenuous and may not provide adequate support for a patient who can only partially assist.
Choice B rationale
While this method may work for some patients, it relies heavily on the patient’s strength and ability to push with their feet. If the patient is weak or unable to exert enough force, this method could be unsafe.
Choice C rationale
Using a device to reduce friction is the most appropriate technique when shifting a patient who can only partially assist. Devices such as slide sheets or transfer boards can help move the patient smoothly and with less physical strain on the healthcare provider.
Choice D rationale
Lifting the patient’s legs while the patient uses a trapeze bar requires significant upper body strength from the patient and may not be feasible for all patients.
