QUESTION 1

Jasper is a 7-year-old boy who has had flu-like
symptoms for several weeks. It was mild at first, but his parents notice that
he has been getting worse. They took him to his pediatrician last week, but he
was sent home with suggestions to use OTC medication to treat his symptoms
while his body recovered from what appeared to be a mild infection. Jasper
appears weak, has lost 3-4 pounds in the last month, and has been complaining
of headaches. Jasper’s parents have now brought him back to the clinic and
another physician orders a CBC.

What is a CBC? In your own words, briefly describe

QUESTION 11

Elsa is an 11-month-old girl. Her parents have
brought her to her pediatrician because they have noticed she seems lethargic
and pale. Both parents have noticed that she appears bloated, doesn’t want to
eat as much as she has before, and is tired and “cranky all the time.” They
suspected she might be suffering from anemia, since she was being fed a
low-iron formula, so they had switched to a high-iron formula. The change made
no difference in her symptoms. The pediatrician notes that Elsa’s belly appears
swollen. Her vital signs show that her temperature is normal and her heart rate
is on the low end of the normal range for her age. She has dropped from the
50th percentile in height and weight (at her last check-up) to the 10th
percentile in both height and weight.

Blood test results:

Hemoglobin: 5 g/dl

RBC: 4.6×106 cells/ml

MCV: 65

QUESTION 15

Elsa’s pediatrician suspects that she has
thalassemia. Which of the following statements is true of thalassemia?

Thrombocytes tend to “stick together” and form blood clots.

Thalassemia is always caused by diet and environmental factors, not genetic
makeup.

Thalassemia is also known as erythroblastic anemia and involves a reduced
amount of hemoglobin in the blood.

Thalassemia is a type of hemophilia and is often hereditary in females.

this diagnosis?

The cause of beta-thalassemia is genetic.

Beta-thalassemia major is a grave condition and has a high mortality rate.

Beta-thalassemia major is often treated with blood transfusions.

Because beta-thalassemia is an x-linked trait, it affects males more often than

Module 02 Discussion – Heart Disease

According
to the Center for Disease Control and Prevention (2015), cardiovascular disease
(CVD) is the leading cause of deaths in the United States, equating to about 1
in every 4 deaths, even though CVD is largely preventable. Recently, various
studies have shown promise with stem cell therapy treating heart disease.

Research
stem cell therapy in the treatment of heart disease and the possible promises
it has as a therapy. In your post, address the following questions.

  • Should
    science and healthcare professionals pursue this a treatment option for
    heart disease? Why or why not?
  • What
    obstacles and issues would scientists need to overcome in order for stem
    cell therapy to become a mainstream treatment for heart disease?
  • Which
    types of CVD could be treated with stem cell therapy?
  • What
    kind of financial/societal impacts would stem cell therapy have on the
    healthcare system?
