Answer:

Plato Answer

Explanation:

Embryonic stem cells are plentiful, and they can create every cell in the human body. Researchers can use these cells to create tissues. They can possibly grow new organs in a lab to treat diseased organs. Adult stem cells are rarer in the human body, and they’re limited in the types of cells they can make.

An embryo can’t grow without its stem cells, so people have ethical concerns about their use. Adults can provide consent to donate their stem cells, so there are fewer ethical issues regarding the use of adult stem cells.

A client whose parkinson's disease is being treated with tolcapone should concurrently take what drug?
steposvetlana [31]

Answer:

The correct answer would be levodopa/carbidopa.

Tolcapone is a drug used as an adjunct to levodopa/carbidopa combination medication.

These drugs are used to treat the symptoms of Parkinson's disease.

Tolcapone is used to inhibit enzyme COMT (catechol-O-methyl transferase).

In the brain, levodopa is converted into dopamine which helps in controlling the movement.

Carbidopa helps in preventing the breakdown of levodopa in the blood which allows more levodopa to enter the brain. In addition, it helps in reducing the side-effects associated with levodopa such as vomiting, nausea et cetera.
