Which framework would best help the PHN understand the multiple risk factors contributing to asthma in this population? o Morbidity- provides information about the risk of disease, rate of disease development and levels of existing disease in the community. Pneumocystis carinii is an organism that harmlessly colonizes the respiratory tract of some healthy persons, but can cause potentially lethal pneumonia in persons whose immune systems have been weakened by human immunodeficiency virus (HIV). Because the agent-host-environment model did not work well for many non-infectious diseases, several other models that attempt to account for the multifactorial nature of causation have been proposed.

A variety of factors influence whether exposure to an organism will result in disease, including the organisms pathogenicity (ability to cause disease) and dose. WebRight-sided vocal fold paralysis would warrant studies which would rule out lesions affecting the vagus nerve or recurrent laryngeal nerve (RLN) from the skull base down to the thoracic inlet. For an epidemiologist, understanding how diseases spread is essential. A public health nurse (PHN) is asked by the hospital administration to find out why there are so many pediatric asthma patients coming to the emergency department (ED) for treatment and to develop a plan to reduce admissions by 10%.
