Which of the following is a manifestation of cor pulmonale contributing to right-sided heart failure?

A. Left-sided weakness may occur with a stroke or focal brain lesion, not typically with meningitis.
B. Nuchal rigidity (stiff neck) is a hallmark sign of meningeal irritation seen in meningitis.
C. Fatigue is nonspecific and can occur in many illnesses but is not a defining feature of meningitis.
D. Chest pain is unrelated to the inflammation of the meninges.

A. Electroencephalogram (EEG) measures electrical activity of the brain, not cardiac function.
B. KUB (Kidneys, Ureters, Bladder) is an X-ray used to assess the urinary tract, not heart function.
C. Dexascan (DEXA) is used to measure bone density, unrelated to heart function.
D. Cardiac catheterization is an invasive diagnostic procedure that allows direct measurement of cardiac pressures and evaluation of coronary arteries. It can be used to assess cardiac function including ejection fraction, either directly or with adjunctive imaging like ventriculography. Additionally, echocardiography is commonly used non-invasively to measure ejection fraction but among the given options, cardiac catheterization is the correct answer
