Mrs. Davenport is already enrolled in a MA plan before she has developed ESRD. Therefore, her plan will continue after getting the ESRD diagnosis and the MA plan chosen by Mrs. Davenporrt cannot charge more than the original Medicare cost for dialysis and coverage of immunosuppressant drugs. Moreover both part A and part B medicare plans have annual budget for out-of-pocket costs thus the increasing healthcare cost of Mrs. Davenport after the ESRD diagnosis can be covered through renewal of annual budgeting. Moreover, if the previous Medicare advantage plan is not functional in the service area, then Mrs. Davenport could enroll in Special Enrollment period and may get another Medicare advantage plan in their area.

alexgriva [62]

Answer:

Las respuestas II, III y IV son correctas

Explanation:

La papera, también conocida como parotiditis, es una enfermedad vírica altamente contagiosa causada por un virus de la familia Paramyxoviridae, la cual se desarrolla principalmente en las glándulas parótidas situadas a ambos lados de la mandíbula. La inmunidad a esta enfermedad puede ser lograda a partir de la aplicación de la vacuna triple viral, cuyo nombre se debe a que esta vacuna también permite adquirir inmunidad contra los virus del sarampión y la rubéola. Por otra parte, la varicela es también una enfermedad muy contagiosa que se presenta generalmente en niños, la cual es causada por el herpesvirus de varicela-zoster. Esta enfermedad se caracteriza por la presencia de erupciones rojas en la piel que causan picazón, lo cual a su vez genera lesiones cutáneas. Tanto la varicela como la papera sólo se producen una vez ya que una vez contagiado el organismo adquiere inmunidad frente a estos virus a través de un mecanismo adaptativo en el cual linajes específicos de linfocitos B capaces de secretar anticuerpos específicos contra ambos virus proliferan rápidamente a través de un proceso conocido como expansión monoclonal, con lo cual el sistema inmune adquiere memoria inmunológica.

ratelena [41]

Answer:

There is no short answer.

Explanation:

Antigen presenting is a term used to describe the action of introducing them to the white blood cells and triggers the production of T cells which are essential to the immune system.

If we complete the sentences given in the question and put them in order;

1 - The antigen presenting cell encounters and processes the antigen.

2 - With the antigen, the antigen presenting cell migrates to the nearest lymph node.

3 -  The antigen presenting cell displays the antigen to the T cells.

4 - The T cells initiate the immune response if the antigens are viral proteins or abnormal antigens.

5 - Infected or malignant cells are then destroyed before they can do further harm to the body.

I hope this answer helps.
