A Typical Human Body Contains About 3.0 Grams Of Potassium Per Kilogram Of Body Mass. 1. ... 1. How much Potassium-40 is present
Studentka2010 [4]

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

A client who has been experiencing prolonged vomiting has the following ABG results: pH 7.48; pCO2 40 mm Hg; HCO3 34 mEq/L; pO2
lesantik [10]

The nurse determines that the client experiencing Metabolic Alkalosis imbalance.


When digestive difficulties throw off the blood's acid-base equilibrium, metabolic alkalosis results. Additionally, it might be brought on by illnesses of the heart, liver, or kidneys. Typically, metabolic alkalosis poses a minimal danger to life. Once it has been treated, it has no aftereffects on your health.

The use of diuretics and external loss of gastric secretions are the two most frequent causes of metabolic alkalosis.

The pH may be high or close to normal in metabolic alkalosis, which is primarily characterized by an increase in bicarbonate (HCO3) with or without a compensatory increase in carbon dioxide partial pressure (Pco2). Prolonged vomiting, hypovolemia, the use of diuretics, and hypokalemia are common reasons.
