Summary Introduction
To explain: The reason why Person E stayed healthy even after exposure to countless virus particles of chicken pox every day.
Introduction: An immune system is a defense system that consists of many biological structures and processes inside an organism in order to protect against the diseases. If the immune system does not function properly, it may lead to many serious disorders. These disorders possess low activity or over activity of the immune system.

- Your grandmother, age 79, says her physician is recommending she get a flu shot. She states she has always been healthy and asks you why she needs this shot.arrow_forwardyou need a flu shot every year/season because (HA-haemoagglutinin; NA-neuroaminidase) A) the virus can change its HA and NA every year, so a new shot is needed to teach your immune system how to recognize the changed HA and NA B) flu virus gets rid of its HA and NA and replace them with completely new ones every year C) your immune system weakens after a year-so you have to get another shot to get the system strong enough to attack the virus D)antigen shift occurs every yeararrow_forwardLet’s say there are two closely related viruses, let’s call them Guernsey virus and Micro virus. These two viruses only infect epithelial cells. Their surface antigens are sufficiently similar that there are a number of shared epitopes between the two viruses. Choose one of the following: A) If you get infected and successfully recover from one virus, it’s quite possible that you’ll have neutralizing antibodies against the other. B) If you get infected and successfully recover from one virus, you’ll still be susceptible to the other one because the antigens aren’t exactly the same. C) If you get infected and successfully recover from one virus, it’s likely that getting infected with the other virus will be worse because of the common phenomena of antibody-dependent enhancement. D) Not enough information has been given.arrow_forward
- When the patient's mother expresses concern about his sister being reinfected with chickenpox, what is the most appropriate response? A) Your concerns are valid, but his sister developed an active natural immunity to chickenpox because she has already been infected. B) Your concerns are valid and there is a high likelihood that his sister will become infected again. We should probably administer the vaccine. C) Your concerns are valid and there is no way to protect his sister from becoming reinfected except to keep her at least 15 feet from your son at all times. D) Your concerns are valid and if his sister is reinfected, her symptoms will be less severe than her initial chickenpox infection.arrow_forwardWhat is one reason SARS-CoV-2 can remain undetected in a person? a.)it isn't able to replicate unless you are also sick with another type of virus b.)its genome produces proteins that prevent our immune system from noticing it c.)it causes your immune system to shut down d.)it is prevented from infecting a cell for one year after entering your bodyarrow_forwardMr. Y’s HIV is being managed on a combination drug regimen that includes two nucleoside reverse transcriptase inhibitors (NRTIs) and one protease inhibitor (PI). His viral load is currently 50,000 copies/ mL; 3 months ago, his viral load was undetectable. His CD4+ T-lymphocyte count is 526 cells/mm3, down from 680 cells/mm3 3 months ago. Although he has been following his HAART regimen, he has experienced multiple complications, including several opportunistic infections. In light of his medical history, Mr. Y is especially concerned about his shortness of breath and hemoptysis. 1.What is the mechanism of action of the NRTI drugs that Mr. Y is taking for his HIV? 2. What is the rationale for the use of combined drug therapy in the treatment of HIV?arrow_forward
- Tom has just been exposed to the measles virus, and he can't remember if he has had measles before. He asks you if there is any way he can tell if he has been previously exposed or if he is going to get sick. What would you tell him? Why won't he get sick from a second infectionarrow_forwardd) After your immune system subdues the virus, you wake up in sweaty clothes. i) Explain generally why you wake up in that state and ii) describe the steps that occur in your body that result in this response. e) Bats have been implicated as the source of many viruses against which humans have a difficult time mounting an effective immune response. Interestingly, flight plays an important role. i) Describe and explain i) the role that flight plays in creating these kinds of viruses, ii) how the viruses cross over into humans, and iii) why our immune response has a more difficult time mounting an effective response against them 4 Temperaturearrow_forwardDuring a routine checkup, a 72-year-old patient is advised to receive an influenza vaccine injection. He questions this, saying, “I had one last year. Why do I need another one?” What is an appropriate response from the nurse? a )“The effectiveness of the vaccine wears off after 6 months.”b) “Each year a new vaccine is developed based on the flu strains that are likely to be in circulation.”c )“When you reach 65 years of age, you need boosters on an annual basis.”d) “Taking the flu vaccine each year allows you to build your immunity to a higher level each time.”arrow_forward
- After young Janie was diagnosed as having acute lymphocytic leukemia, her parents could not understand why infection was a major problem for Janie when her WBC count was so high. Provide an explanation for Janie’s parents.arrow_forwardAfter his recovery from chickenpox, which lymphocytes will keep this patient from becoming infected again? A) T helper cells B) Natural killer cells C) T memory cells D) B cellsarrow_forwardDianne is an avid tennis player but has recently been complaining of tendonitis in her elbow.
