-Ultraviolet (UV) exposure – The sun is the most well-known source of UV radiation, but UV rays also come from tanning beds and other artificial sources.
-Genetics – Some risk factors of skin cancer can be inherited through our DNA.
-Immunosuppression – Some conditions, like AIDS, and certain medications, such as those provided after organ transplants, can suppress the body’s immune system and might contribute to the development of skin cancer.
-Radiation exposure – In addition to UV, there are other forms of radiation that may adversely affect the skin cells, such as X-rays or therapeutic radiation.
-Toxic sunscreens -- Most sunscreens block the absorption of Vitamin D with toxic chemicals that seep through the skin and into the bloodstream and all throughout your body. Using these toxic sunscreens could actually cause cancer. Some toxic ingredients that are in these kinds of sunscreens: oxybenzone. benzene, parabens, homosalate, octinoxate, and octocrylene
Caucasians are more at risk for skin cancer because they have less melanin produced in their skin. Lighter skin tones produce less melanin and are more prone to damaged DNA particulate from UV radiation.
Here, the rate of infusion is 40mLs/hr.
<h3>What is Infusion?</h3>
An infusion may be defined as a process of being extracted some compounds from original products.
To find the dose required = 0.5 (mg) x patient weight (kg)
= 0.5mg x 80 = 40mg
Available Aminophylline is 500mg in 500 mLs = 1mg in a mL
To find the actual rate of infusion = 
= 
= 40mLs/hour.
Therefore, the rate of infusion is 40mLs/hr.

Answer:
All options are correct.
Explanation:
Fibers may be defined as the type of carbohydrate that cannot be digested by the body. Two main types of fiber are soluble fibers and the insoluble fibers.
Fibers play an important role in the body. Fibers manage the blood sugar level and prevent constipation. The fibers also helps in the reduction of the absorption of cholesterol in the body. Insoluble fibers prevent constipation and soluble fibers maintains blood sugar level.
Thus, all the given options are correct.
Answer:
BBBBBBBBBBBBBBBB im not sureeee hehe
The nurse should administer 0.8 mL ceftriaxone IM.
<h3>How to calculate the value?</h3>
Determine the infant's weight in kg: 2.2 lb / x kg
= weight in lb / 1 kg; 2.2 lb / x kg = 17.6 lb / 1 kg.
Cross multiply and x = 8 kg
Find total of one-time dose:
Amount prescribed x kg weight (mg x kg)
= total daily dose; 50 mg x 8 kg = 400 mg
What is the dose needed?
Dose needed = Desired; Desired = 400 mg
What is the dose available?
Dose available = Have; Have = 500 mg
Set up an equation using knowledge about basic equivalents.
Desired x Quantity / Have
= Amount to be given; 400 mg x 1 mL / 500 mg = x mL; 400 x 1
= 400 ÷ 500 = 0.8 mL
