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 D
Explanation
Choice A rationale
A biopsy is not typically prescribed for plantar warts unless there is suspicion of a more serious condition, such as cancer.
Choice B rationale
Soaking feet in an antiseptic solution daily is not a standard treatment for plantar warts. Standard treatments include salicylic acid, cryotherapy (freezing), and other methods.
Choice C rationale
Plantar warts are not directly related to excessive foot perspiration. They are caused by the human papillomavirus (HPV) entering a cut or break in the skin.
Choice D rationale
Plantar warts may cause discomfort during walking due to their location on the soles of the feet.
Correct Answer is B
Explanation
Choice A rationale
The Scale for Assessment of Negative Symptoms (SANS) is a tool used to assess negative symptoms in schizophrenia and is not typically used in the assessment of cognitive disorders.
Choice B rationale
The Mental Status Examination (MSE) is a key part of the clinical assessment process in psychiatric practice. It is a structured way of observing and describing a patient’s current state of mind, under the domains of appearance, attitude, behavior, mood and affect, speech, thought process, thought content, perception, cognition, insight, and judgement.
Choice C rationale
The Abnormal Involuntary Movements Scale (AIMS) is a rating scale that measures involuntary movements known as tardive dyskinesia (a side effect of long-term use of antipsychotic drugs). It is not typically used in the assessment of cognitive disorders.
Choice D rationale
The Mini-Mental State Examination (MMSE) is a commonly used test for complaints of memory problems or when a diagnosis of dementia is being considered. However, in this case, the MSE would be a more comprehensive tool.
