- As a doctor, you have samples of A-, A+, B-, B+, AB-, AB+, O-, and O+ blood in a hospital supply center. You order a blood sample to be taken from the patient. How could you use process of elimination to figure out the patient’s blood type?Your patient, Sally Sue who has AB- blood, receives blood from her older sister (Ruby, who’s AB+). Afterwards, she has a cytotoxic reaction. Which of the following was the initial cause of the reaction? Sally Sue’s blood type was actually AB+ Sally Sue had previously received AB+ blood Ruby’s blood type was actually AB- Sally Sue had previously received A- blood Sally Sue had previously received B- bloodIf you tested a sample of blood and it clumped in serum A, but did not clump in serum B, or the Rh serum, what kind of blood would you have? A) O+B) B-C) AB+D) A+E) A-
- Ms. Wu, whose blood type is O-, requires a blood transfusion.Her family members volunteer to donate blood. Their blood types are as follows: her son, type B-; her husband, type B+; her daughter, type O+. Which family members could safely donate blood to Ms. Wu? Who could not? Explain.After observing the following image, you can make which of the following statements? Choose from the following: (A) antibody A reacted with antigen A (B) antibody B reacted with antigen B (C) Rh antibody reacted with Rh antigen (D) none of the above occuredA patient is rushed to the emergency room and has suffered severe blood loss. Type AB blood is in short supply, but the nurse says “Don’t worry, he’s type AB positive. We can give him any kind of blood.” Explain. (Why is type AB called the universal recipient?)
- Select the best answer or answers from the choices given: Suppose your blood is AB positive. This means that (a) agglutinogens A and B are present on your red blood cells, (b) there are no anti-A or anti-B antodies in your plasma, c) your blood is Rh+ (d) all of the above.You have a patient with prostate cancer. The cancer causes blood vessels to weaken and burst. The patient has a dangerously low Hematocrit and needs a blood transfusion. When you test his blood for type, here are the results: Anti-A- agglutination, Anti-B- agglutination, Anti-Rh- no reaction. 1. List all blood types he can receive. When you enthusiastically suggest that blood transfusions will help him, he protests that his religious beliefs disallow him from accepting transfusions. You will need to find a way to help his own body both retain the blood he has, and make new blood. 2. Based only on what we've learned so far re: blood and endocrine, come up with hypotheses about how you could do each. 3. Propose a mechanism of how EPO might work: what cells might it target, would it enter them, and what sorts of proteins might it activate? (This question references endocrine: how hormones work, and why it matters if they are water-soluble or fat-solube) 4. There is a drug called…When a mother is Rh-, there is a chance the baby may have hemolytic disease of Newborns. Rh+ mothers do not have this issue. Why? Rh- moms do not have the Rh antigen in their body. A Rh- mom can have a Rh+ baby depending on the male sperm. During pregnancy, Rh- mom can be exposed to her baby's Rh antigen. Let's look at figure a) the first pregnancy. The Rh- mom is pregnant with a Rh+ baby. The baby exposes the mom to Rh antigen during pregnancy. This first baby is delivered and is ok. Figure (b) between pregnancies, the mother is exposed to the foreign antigen Rh and she makes antibodies against Rh. She now has anti-D (anti-Rh) in her body. Figure (c) her second pregnancy with a Rh+ baby. On the next pregnancy that the mom has with a baby. The mom has the anti-D (anti-Rh) antibody in her system. The antibody will attack the baby's RBCS with the Rh antigen on it. When the baby's RBC's are attacked the RBC will hemolyse (hemo=RBC; Lysis=cut). This will result in severe anemia. The lysed…
- Bill is homozygous for B antigens. Janet is IAi. What percentage of their offspring will have Type AB blood?
