• Discussion Question : Describe one physical, chemical, biological or psycho-social stress hazard that workers can be exposed to on the job, and one strategy that can be implemented to prevent or reduce the exposure. Why is it important for primary healthcare providers, (physicians, nurse practitioners, and physician assistants) to ask patients about their occupation when performing routine physical exams?

Mr. V is a 55-year-old alcoholic who checked into a clinic, complaining that he has been experiencing a persistent cough and feeling more fatigued, nauseous, and irritable. In addition, he is experiencing more frequent memory lapses. His stomach is distended, but on palpation, his liver is small in size and firm, indicating cirrhosis. Lab tests indicate a decrease in hemoglobin, albumin, levels with elevated serum bilirubin and ammonia levels.

a) Provide a specific rationale for each of Mr. V’s manifestations and blood values.

b) what is the prognosis?

1. At the peak of an action potential, the membrane potential of a human motor neuron reaches about +30mV. What value for “alpha”, the ratio of PNa/PK, allows this to occur. Use an online calculator/simulation to find a value for alpha that approximates what happens to reach this membrane potential, and write out the entire GHK equation (the version with just sodium and potassium) that can produce this membrane potential, including normal ion concentrations and temperature.

Choose any system of the human body and prepare a response to the following questions--> What body system do you have the best understanding of and why?

Correlate muscle physiology to normal body function.

Over the long-term (years), the physical changes to the heart and the reflexes may not be able to compensate for the aortic valve stenosis and the left ventricular cardiac output will decrease. This will lead to the accumulation of blood in the pulmonary circuit and in the system circuit veins. Describe what you predict would happen at the pulmonary capillaries and capillaries in the lower extremities in the systemic circuit. (Be sure to include all of the relevant variables for the capillaries and which ones are changed in this situation).
