Hiv directly infects t-cells. Why is this problematic for cell-mediated immunity?

Answers

Answer 1
Answer:

Answer:

Cell-mediated immunity is the function of phagocyte and cytotoxic T-cells. It does not involve antibodies and is specific for a particular antigen.  

In HIV infection the virus enters into the T-helper cell(CD 4 cell) and reproduces in the T helper cell. They destroy the T helper cell during this process and then enter new CD 4 cell. By this process, they reduce the number of T helper cells.

T helper cell are important for cell-mediated immunity because it releases some chemicals that activate cytotoxic T cell and phagocytes which then kill the pathogens.  

Therefore when the number of T helper cells reduces it becomes problematic for cell-mediated immunity to function properly.

The nurse has completed medication education with the patient who is receiving risperidone (Risperdal). The nurse evaluates that the education has been effective when the patient makes which statement?

Answers

Answer and Explanation:

  Risperidone is a potent atypical antipsychotic drug. It is a selective monoaminergic antagonist with unique properties.  It has high affinity for 5-HT2 serotoninergic and D2 dopaminergic receptors. Risperidone also binds to alpha-1 receptors  adrenergic and, with lower affinity, histamine H1 and alpha2 adrenergic receptors. Risperidone does not have  affinity for cholinergic receptors. Although risperidone is a potent D2 antagonist, this is considered  responsible for improving the positive symptoms of schizophrenia, its depressant effect on  motor and catalepsy inducer is less potent than classical neuroleptics.

    It is most often used in the treatment of delusional psychoses, including schizophrenia. However, risperidone, like other atypical antipsychotics, is also used to treat some forms of bipolar disorder, depressive psychosis, obsessive compulsive disorder, and Tourette's syndrome. In the United States, it has also been approved for the treatment of irritability in children and adolescents (although is not recommended for the treatment of autism spectrum disorders and milder forms of autism due to its effects).

Tiffany has a hard time trusting other people her age because she believes they are irresponsible. Accordingly, when she makes dinner plans with one friend, she also makes backup plans with someone else, and she goes to one or the other. Her friends soon in turn begin to "blow off" their arrangements since it is not clear whether or not Tiffany will show up. Tiffany has created ___________.a. a confirmation bias.b. a self-fulfilling prophecy.
c. counterfactual thinking.
d. controlled unbelieving.

Answers

Answer:Tiffany has created a self-fulfilling prophecy. The correct option is B.

Explanation: self- fulfilling prophecy is created when an individual expects or believe a particular thing to happen and this expectations occurs due to the individuals behavior.Self-fulfilling prophecy has to do with our psychological way of thinking and how it eventually affects our actions. Because Tiffany has an already concluded mindset that people she dates are irresponsible. That what led to her actions of double dating. Her dates in turn started "blowing her off " because of her short comings. I hope this help. Thanks.
