Sickle cell disease is caused by a point mutation in the 6th codon of the beta-globin chains, leading to the substitution of glutamic acid with valine.
This mutation results in abnormal hemoglobin, called hemoglobin S (HbS), which causes red blood cells to assume a sickle shape under hypoxic conditions. The pathophysiology of sickle cell disease is centered around the polymerization of HbS under low oxygen levels. The sickle-shaped red blood cells are less flexible and more prone to clumping, leading to vaso-occlusive events, ischemia, and tissue damage. Furthermore, these abnormal cells have a shorter lifespan, contributing to hemolytic anemia.
Crisis symptoms in sickle cell disease can manifest as sudden fever, severe localized pain, and tenderness, often in the chest or ribs. These symptoms result from vaso-occlusion and subsequent tissue ischemia. A peripheral blood smear may reveal the presence of sickle cells, confirming the diagnosis. Proper management of sickle cell crisis typically involves pain relief, hydration, and oxygen therapy to mitigate hypoxia and alleviate symptoms.

4. Mrs. Robins states that she should not have her blood pressure taken on her left arm
because she has had a mastectomy. She indicates that her lymph nodes were also removed on
that side and the doctor told her not to have her blood pressure taken on that side. Why would a
doctor say this? You may need to refer to the Internet for the reason why
Answer:
Its precautionary to prevent lymphedema.
Explanation:
Sometimes, removing lymph nodes can make it hard for your lymphatic system to drain properly. If this happens, lymphatic fluid can build up in the area where the lymph nodes were removed. This extra fluid causes swelling called lymphedema.
The surgical partial or total removal of one or both breasts is referred to medically as a mastectomy. Breast cancer is typically treated with a mastectomy. Women who are thought to have a high risk of developing breast cancer occasionally have the procedure done as a preventative step.
What is Lymphedema?Lymphedema is caused by a blockage in the lymphatic system. This is usually the result of a traumatic event, such as a sports injury or deep cuts and bruises, or as a side effect of surgery or cancer treatment. Lymphedema can occur as a birth defect or as a symptom of infection in rare cases. Precautions are required to prevent lymphedema. When lymph nodes are removed, your lymphatic system may struggle to discharge properly on occasion. If this occurs, lymphatic fluid may accumulate where the lymph nodes were removed. Lymphedema is a swelling caused by extra fluid. It is critical to understand that lymphedema can sometimes become severe and cause serious problems, and that it is frequently a long-term or chronic condition.To learn more about Mastectomy refer to:

cell membranes are not fully permeable
Answer:
They are semi permeable
Explanation:
Mean that some molecules can diffuse across the lipids bilayer but other cannot.
This statement is true. Cell membranes exhibit two principles called selective permeability and semi-permeability, often incorrectly used interchangeably! The first means that the composition of the cell membrane allows for some specific molecules to perfuse into and out of the cell while disallowing other specific molecules, depending on certain cellular conditions, properties, functions, and metabolic activity. If the cytoplasm is a party, the cell membrane is the security guard that checks the list and either bounces guests or lets them pass the stanchion. The second means that the membrane distinguishes which molecules can pass according to their size, electrical charge, solubility, and other properties (chemical or physical) that fit or do not fit the cell's needs.
