Answer: d. Confounding
Explanation:
In the context of a scientific study such as this one, a confounding factor is one that has influence on both the exposure and event variable(s), which may lead to over- or underestimation of the direct relationship between them (if any).
For instance: In this example, researchers may have had reason to believe that male gender is associated with both higher risk of obesity (the exposure variable) and adult-onset asthma (the event variable). If gender is not taken into account, one may claim that the finding of an association between obesity and asthma is simply an artifact due to the high proportion of male patients (likely to present with both). <em>Controlling</em> for that variable (such as by matching, as in this example) allows researchers to test for this hypothesis.
Answer:
Given
Per Kg of body mass, there is 3 gram of potassium
And abundance of three isotopes are as follows
Potassium-39, Potassium-40, and Potassium-41. Have abundances respectively as 93.26%, 0.012% and 6.728%.
1) A body weighing 80 Kg will have 240 grams of potassium. And the amount of Potassium-40 will be 0.012% of 240 gram
= 240*0.012/100 = 0.0288 gram.
2) Dose in (Gy) = (energy absorbed)/(mass of the body) = ( 1.1*106*1.6*10-19)/(80) = 22*10-10 J/kg
Dose (in siverts) = RBE*Dose(in Gy) = 1.2*22*10-10 = 26.4*10-10
Answer:
The correct answer is option C.
If the arterial blood gas (ABG) test result is Respiratory Alkalosis, it indicates that the patient has a risk of experiencing early shock.
Explanation:
Respiratory alkalosis is a condition where the physiological pH of the blood is altered. It is caused by a high amount of carbon dioxide in the blood which triggers the acid-base imbalance.
Patients generally suffer from respiratory alkalosis during hyperventilation. Hyperventilation is cognition where the breathing pattern is rapid and uncontrolled.
Shock is a pathological condition where the blood flow to a particular region of the body is reduced or stopped. Shock may even lead to life-threatening situations. Respiratory alkalosis serves as an early symptom of shock.
