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

AlexFokin [52]

Safe patient handling and mobility (SPHM) and preventing physical injury is a professional, legal, and ethical concern that applies to: patients, family members, and intra-professional health providers.

Safe patient handling and mobility (SPHM) is a professional, legal, and ethical concern that typically involves the use of assistive devices or equipment, so as to ensure a patient is safely mobilized and that health-care providers avoid high-risk manual patient handling tasks.

Some of the advantages of safe patient handling and mobility (SPHM) include:

  • Preventing physical injury to both the patient and care provider.
  • It improves the safety of a patient.
  • It enhances the quality of care received by a patient.

In a case-control study of obesity and adult-onset asthma, controls are matched to cases on the basis of race and gender.
Bess [88]

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.

Jlenok [28]

Answer:

The answer is A a loss of surfactant.

Explanation:

The surfactant is a liquid that intervenes in the capillary-alveolus interface favoring the exchange of gases (oxygen, CO2) at this pulmonary level. For this reason, damage to type II pneumocytes will produce an alteration of this exchange.
