The PMHNP is evaluating a new patient, a 31-year-old woman who was referred by her primary care provider (PCP). She complains of feeling fatigued for the past 3 months, and this fatigue has caused her to stop socializing. Upon further questioning, she reports feeling uncomfortable sensations in her legs in the evenings. She describes the sensations as burning and tingling, and states that she has to walk around to get any relief. Which diagnosis best fits her clinical picture?

Choice A reason: ARDS is characterized by acute onset of hypoxemia and bilateral pulmonary infiltrates not fully explained by cardiac failure or fluid overload. The hallmark radiographic finding is diffuse bilateral opacities on chest imaging, which reflect alveolar damage and fluid accumulation. This is the most consistent and diagnostic imaging feature of ARDS.

Choice B reason: Hyperinflation, flattened diaphragm, and increased anterior-posterior diameter are typical findings in obstructive lung diseases such as chronic obstructive pulmonary disease (COPD), not ARDS. These features suggest air trapping rather than alveolar flooding or collapse.

Choice C reason: Increased interstitial markings and thickened bronchial walls are more indicative of chronic bronchitis or other interstitial lung diseases. These findings are not specific to ARDS and do not reflect the acute alveolar injury seen in ARDS.

Choice D reason: Consolidation or parapneumonic effusion may be seen in bacterial pneumonia or other infectious processes, but they are not characteristic of ARDS. ARDS typically presents with diffuse, non-lobar infiltrates rather than focal consolidation.

Choice A reason: While testicular cancer is most common in men aged 15–35, limiting self-exams to this age range may miss cases in older men. Monthly self-exams are recommended starting at age 18 and continuing throughout adulthood.

Choice B reason: This age range excludes younger men who are at higher risk for testicular cancer. It is not consistent with preventive guidelines.

Choice C reason: Testicular cancer is less common in men over 45, and this age range does not reflect the peak incidence period.

Choice D reason: Monthly testicular self-exams are recommended for men aged 18 and older to promote early detection of testicular cancer, which has a high cure rate when caught early. Regular self-exams help men become familiar with their baseline anatomy and detect changes promptly.
