Question

6- The important stage of risk management are: (a) Hazard Identification, Dose-Response Assessment, Exposure Assessment, Risk Characteristics (b) Hazard Definition, Dose-Response Identification, Exposure Definition, Risk Identification (c) Hazard Characterization, Dose-Response Assessment, Exposure Assessment, Risk Characteristics (d) Hazard Characterization, Dose-Response Management, Exposure Identification, Risk Identification 7. The risk can be calculated as; (a) Risk is equal chronic daily intake multiplied by potency (b) Risk is equal chronic daily intake multiplied by body weight (c) Risk is equal chronic daily intake multiplied by daily dose (d) Risk is equal potency multiplied by body weight 8. For the Gaussian distribution, the standard deviation is a measure of the width of the Bill- Shaped Curve and equal to: (a) 68.3% of the area under the curve (b) 86.3% of the area under the curve (c) 69.3% of the area under the curve (d) 67.3% of the area under the curve 9. For the typical growth curve for bacterial population. The stationary phase represents the following: (a) Food starts to be increased, the growth become almost stationary (b) Food starts to be depleted, the growth become almost depleted (c) Food starts to be increased, the growth become almost depleted (d) Food starts to be depleted, the growth become almost stationary 10-If the relative risk is less than 1 in the population of people having different exposures to risk, then; (a) There is no association between exposure and risk (b) There is association between exposure and risk (c) There is strong association between exposure and risk (d) There is less association between exposure and risk

Answer 1

Q.6 Risk Management:-Option "a" is correct. Steps to be followed in risk management are Hazard Identification, Dose Response Assessment, Exposure Assessment, risk characterization and then taking action and their after reviewing the same. Q. 7 Option "a" is correct. Risk is calculated by multiplying potency factor or slope factor by the chronic daily intake quantity. Whereas the potency factor (Risk corresponding to chronic daily intake of 1 mg/Kg-day is slope of the dose response curve Q. 8. Option "a" is correct. For Guassian distribution, the standard deviation is a measure of the width of the Bill shaped curve. About 68.3 % area of the curve is covered within one standard deviation Q.9. Option "d" is correct. Stationary phase come in to picture when any of nutrient start depleted therefore the dividing of bacterial cells equals to the cells dying. In stationery phase Food starts to be depleted, the growth become almost stationary. Q. 10. Option "b" is correct. If relative risk is less than 1 then its means there is association between exposure and risk. Relative risk is less than 1 give inference that risk of outcome is decreased due to exposure.
