ivolga24 [154]

Answer: Option 1) Medicaid

Explanation:

Through the value based purchasng initiative enacted by Affordable Care Act, in US Healthcare, decided to expand the services of medicaid.

Medicaid provide government sponsored insurance program to the individuals with low income. Medicaid expansion involves that it wil provide long term health care services and pay all the health benefits for more than 70 million people.

Medicaid expansion become efficient health care program as it covers populations with low income, including young children, pregnant women and physically or mentally disable adults. Peopleadded in this program on different eligibility varies widely among states to meet all the states with minimum federal need.

Explanation:

The lymphatic system of the body works by filtering the blood and remove the harmful pathogen that is present in it.

There are several organs in the lymphatic system that works together at different sites in the body and helps body prevent and cure from infection.

Lymph nodes function to remove pathogen and debris from lymph and it is also referred as filters of lymph. The macrophages and dentritic cells kill the harmful pathogen in the blood.

Hence, the correct answer is option A

How could you explore the origin of the different types of blindness?

igor_vitrenko [27]

Answer:

Common causes of blindness are diabetic neuropathy, glaucoma and cataracts.

Explanation:

Blindness refers to the complete lack of functional vision.It occurs when an inadequate amount of light hits the retina, or the information has not been delivered to the brain correctly.

Complete blindness : characterized by a complete and total loss of vision. Merck Manuals reports that legal blindness is defined as having equal to or worse than a 20/200 visual acuity in the better eye. Having a visual acuity of 20/200 means that someone with normal vision can see an object at 200 feet, and a person with impaired vision can see at a distance no further than 20 feet. Several different diseases can cause complete blindness; some develop later in life and some are present at birth. The leading cause of blindness in the United States is diabetes, according to the National Eye Institute. Diabetes causes diabetic retinopathy, which results in destruction of the retina. Other causes of complete blindness include age-related macular degeneration, which the National Eye Institute calls the most common cause of blindness in adults who are 60 or older; cataracts, which obstructs light from hitting the retina because of opaque patches on a lens; and glaucoma, which causes blindness due to damage to the optic nerve.

Color Blindness :

People who have color blindness, also called dyschromatopsia, are unable to distinguish certain colors. This type of blindness more commonly affects men than women. Merck Manuals reports that the most common form of color blindness is red-green color blindness, which makes it difficult to distinguish certain shades of red and green. Color blindness is almost always present at birth, and is usually caused by the presence of a defective gene on the X chromosome. The reason that more men are affected by color blindness than women is that women have two X chromosomes; thus, even if they are "carriers" of a bad gene, their other X chromosome usually has a functional gene. Because men have only one X chromosome, the presence of one bad gene is sufficient to cause color blindness. Defective retinal cells result in some forms of color blindness; other forms are caused by defects in the optic nerve.

Night Blindness :

Night blindness is vision impairment that occurs at night or when light is dim. It does not generally result in a complete lack of vision but significantly impaired vision. People with night blindness often have difficulty driving at night or seeing stars. Several different factors cause night blindness, according to the University of Maryland Medical Center. These factors include cataracts, birth defects, a vitamin A deficiency, or a retinal disease called retinitis pigmentosa

Hoochie [10]

Following the presentation of research or a treatment to the participant or patient, a follow-up study is conducted. It is used to determine whether participants are still experiencing the effects of the treatment condition.

Clinical research is an organized study of human biology, health, or disease that involves actual people.
Clinical research aims to discover or add to generalizable knowledge about human health and illness as well as evaluate potential approaches that could help us be better at preventing, diagnosing, and treating illness as well as patient care.
The nurse's responsibilities may also include providing general education or information on clinical research, responding to inquiries about particular trials, consulting with clinical research staff, referring patients, and working with clinical research.

Put the following events of the adaptive immune response in the order they occur.

LenKa [72]

Answer:

The immune response to infection, of whatever kind, is vital for human survival. At its core lies the cells, and enzymes, as well as chemical components, that will activate these responses, the innate, and the acquired immune response.

Although still under lots of study, and science finding new things in this complex system, the order of the steps in which the system is activated, roughly, is this:

1. C. You cut yourself and bacteria enter the wound.

2. F. A dendrite near the cut phagocytizes some bacteria and uses MHC proteins to present exogenous antigens from the destroyed bacteria on its surface

3. A. The antigen-presenting macrophage and some of the bacteria, enter the lymph and float down a lymph vessel to the lymph node, where T cells are awaiting to recognize it and act.

4. E. Helper T cells at the lymph node use their T cell receptors to bind the antigens on the surface of the dendrite and bacteria. This triggers the helper T cells to reproduce, differentiate and release cytokines and other elements that increase inflamation and activate other immune cells.

5. G. Also, B cells at the lymph node use their B cell receptors to bind to the antigens on the surface of the bacteria and dendrite. These B cells also bind to the cytokines being produced. This triggers the B cells to reproduce and start making antibodies. They also trigger cytotoxic T cells CD4 and CD8 differentiation and activation.

6. B. All the elements produced flow through the blood, activating other immune responses and migrate them towards the site of infection. Because of the inflammation, and thanks to the cytokines and protoinflammatory elements, more cells are activated and they can penetrate the inflammed tissue.

7. D. Through the actions of the antibodies, cytokines, chemicals, and different actions of the cells, phagocytes, and cytotoxic T cells are finally able to destroy the invading bacteria and kill all infected tissue as well, leaving behin scar tissue at the site of the wound, and both B and T cells activate their memory capacity, so that if a new infection by that microorganism happens again, the response will be much faster and efficient.

This is a very broad organization of the immune response.
