An 8-year-old child undergoes tonsillectomy. what is the priority action in the immediate postoperative period?
lyudmila [28]

Positioning the child on the side (side-lying position) is the priority action after tonsiloectomy. It will permit the flow of secretions (like blood) from the mouth that could block the child's airway (airway patency is the priority). So, the most important thing is to maintain an open airway. Excessive coughing could actually trigger bleeding. The child will be on nothing-by-mouth status during the immediate postoperative period.

Duchenne muscular dystrophy is a serious condition caused by a recessive allele of a gene on the human x chromosome. the patient
Dafna1 [17]
<span>Very very unlikely. Since the recessive allele is on the X chromosome, in order for a woman to have this condition, both copies of her X chromosome has to have the recessive allele. One copy of the allele would have to come from her mother, and the second copy from her father. The copy from her mother is a 50/50 chance if her mother was heterozygous with one copy of the recessive allele and one copy of a normal allele and therefore didn't exhibit the dystrophy and therefore didn't know she was a carrier. But the father only has 1 copy of the allele and therefore would exhibit the dystrophy and as such would be unlikely to have engaged in procreative sex that would pass on the defective allele to his offspring. This is especially true since duchenne muscular dystrophy will typically start to manifest itself in male children around starting around age 4.</span>

What are the benefits of using gold?
Snowcat [4.5K]
<span>You can protect your savings against the currency devaluations.You can protect your purchasing power as inflation is steadily rising.You can protect yourself should a severe banking crisis occur, should one of the big banks collaps for example.You can protect your portfolio and wealth if an economic crisis in China, the US or Europe occurs. Even if an economic crisis would result in (temporary) deflation, you would be relatively better off with gold than being in paper money or paper assets.You can protect yourself against the uncontrolled actions of governments, who have excessive debts and try to solve it with huge money printing. Trying to solve the problem of too much debt by creating even more debt is really strange. Anyway someone has to pay the bill … you better be sure it’s not you.You have no counterparty risk with gold and silver (contrary to paper assets where there is always a counterparty risk involved)<span>You should own gold and silver because the trend is your friend. Look at thes 7 charts that prove we are in a major wealth cycle in gold and silver. What is more easy than being invested  in the trend ?</span></span>

When the neuron is at rest, what is primarily responsible for moving potassium ions OUT of the cell?
ruslelena [56]

When the neuron is at rest, what is primarily responsible for moving potassium ions OUT of the cell?

a concentration gradient

an electrical gradient

both a concentration gradient and an electrical gradient

the sodium-potassium pump

Answer:

a concentration gradient

Explanation:

At rest, the sodium-potassium pumps pump the two potassium ions into the cell for three Na ions moved out of the cell. This creates a higher potassium concentration gradient inside the cell. This concentration gradient moves the K+ out of the cell. Movement of positively charged K+ out of the cells make the inside of the membrane negative with respect to the outside. This is how the negative resting potential is maintained when neurons are nor firing the action potential.
