The use of GIS (Geographic Information System) may be thought of as following the heritage of Snow, who used geographic mapping techniques to study the spread of cholera in London in the mid-1800s.
Today, GIS is commonly used in public health research to analyze and visualize data, including content loaded with geographic information such as disease incidence, environmental exposures, and social determinants of health. While Hippocrates, Graunt, Koch, and Semmelweis made important contributions to the field of medicine, their work did not involve the use of GIS technology.

T/F : according to the dopamine hypothesis of schizophrenia, the disorder reflects diminished activation of nmda receptors in the brain.
According to the dopamine hypothesis of schizophrenia, the disorder reflects diminished activation of nmda receptors in the brain. This statement is false.
The disorder reflects an abnormal increase in dopaminergic activity in certain brain regions, particularly in the mesolimbic pathway. This hypothesis suggests that the symptoms of schizophrenia, such as hallucinations and delusions, are caused by an overactivity of dopamine transmission.
The NMDA (N-methyl-D-aspartate) receptor hypothesis, on the other hand, proposes that abnormalities in the function of NMDA receptors contribute to the development of schizophrenia. It suggests that dysfunction of the NMDA receptor system leads to an imbalance between excitatory and inhibitory neurotransmission, resulting in cognitive impairments and psychotic symptoms.
While both hypotheses offer explanations for the neurobiological mechanisms underlying schizophrenia, they focus on different neurotransmitter systems. The dopamine hypothesis emphasizes the role of dopamine dysregulation, while the NMDA receptor hypothesis highlights abnormalities in glutamate neurotransmission.
Therefore, the statement that the dopamine hypothesis suggests diminished activation of NMDA receptors in the brain is incorrect.

a hospice nurse performs a follow-up telephone call to the spouse of a client who died about 1 year ago. the spouse tells the nurse, "i'm always feeling so sad. life just doesn't feel worth living." further conversation reveals that the spouse is having trouble sleeping and eating since her husband's death and that the spouse is "drinking more since he died." the nurse identifies which nursing diagnosis as the priority?
The nurse should prioritize the diagnosis of "Ineffective coping, particularly grief and mourning" for this patient. The patient's statement that she is feeling sad and life does not feel worth living, as well as her difficulty sleeping and eating, indicate that she is experiencing significant emotional distress related to the loss of her husband.
The statement that she is "drinking more since he died" suggests that the patient may be using alcohol as a coping mechanism to deal with her grief. The diagnosis of ineffective coping, particularly grief and mourning, is relevant because it recognizes that the patient's grief is a normal and natural response to loss, but that she may be struggling to cope with her emotions in an effective way. This diagnosis would guide the nurse in developing a plan of care that addresses the patient's emotional needs and supports her in finding more adaptive ways to cope with her grief.

from the following list, select the factor(s) that are most likely to impact image spatial resolution: i. part thickness ii. anode heel effect iii. pathology iv. sid
The factor that is most likely to impact image spatial resolution from the given list is "part thickness". This is because the thickness of the body part being imaged can affect the sharpness and clarity of the resulting image. The thicker the part, the more scatter radiation is produced, which can decrease the image quality.
The other factors listed - anode heel effect, pathology, and sid - can also have an impact on image quality but are not as directly related to spatial resolution. Anode heel effect can affect the intensity of the x-ray beam, pathology can introduce artifacts, and sid can affect magnification and distortion. However, in terms of spatial resolution specifically, part thickness is the most important factor to consider.
The factor most likely to impact image spatial resolution in this list is iv. sid (Source-to-Image Distance). Spatial resolution is influenced by the distance between the X-ray source and the image receptor, as a larger distance reduces geometric unsharpness, leading to improved spatial resolution.
Factors i. part thickness and iii. pathology may affect image contrast but do not have a direct impact on spatial resolution. ii. anode heel effect affects the distribution of X-ray intensity across the image but does not directly influence spatial resolution.
