Hemoglobin is a complex protein that contains four polypeptide chains. The normal hemoglobin found in adults—called adult hemoglobin—consists of two alpha and two beta polypeptide chains, which are encoded by different loci. Sickle-cell hemoglobin, which causes sickle-cell anemia, arises from a mutation in the beta chain of adult hemoglobin. Adult hemoglobin and sickle-cell hemoglobin differ in a single amino acid: the sixth amino acid from one end in adult hemoglobin is glutamic acid, whereas sickle-cell hemoglobin has valine at this position. After consulting the genetic code provided in Figure 15.10, indicate the type and location of the mutation that gave rise to sickle-cell anemia.

Answers

Answer 1

GAA and GAG are two potential codons for glutamic acid. Codons that encode valine can be created by making a single base substitution in the second position in both codons: GAA-> GUA (Val), (Val) GAG -> GUG (Val)

What occurs if hemoglobin levels are low?

Being anemic, or having low hemoglobin, can make you feel exhausted and frail. Anemia can have many different forms, each with a unique etiology. Anemia can be mild to severe and can be short-term or long-term. Anemia typically has multiple causes.

What hemoglobin level is considered dangerously low?

According to some physicians, hospital patients with hemoglobin levels below 10 g/dL ought to have a blood transfusion. A blood transfusion may not be necessary for many individuals with levels between 7 and 10 g/dL, according to current studies. One blood unit is typically just as effective as two and may even be safer.

The surgical removal of a gland

Answers

Answer:

The surgical removal of a gland is called a glandectomy. A glandectomy is a surgical procedure that involves the removal of one or more glands from the body. Glands are organs that produce and secrete substances such as hormones or enzymes, and they play an important role in regulating various body functions. However, in some cases, glands may become diseased or damaged, and they may need to be removed in order to restore health or prevent further complications.

There are several different types of glandectomies, depending on the gland or glands that are being removed. For example, a thyroid glandectomy involves the removal of the thyroid gland, which is located in the neck and produces hormones that regulate metabolism. A parathyroid glandectomy involves the removal of one or more parathyroid glands, which are located near the thyroid gland and produce a hormone that regulates calcium levels in the blood. A salivary glandectomy involves the removal of one or more salivary glands, which are located in the mouth and produce saliva.

Glandectomies are typically performed by a surgeon, and they may be done using traditional open surgery or through minimally invasive techniques such as laparoscopy or robotic surgery. The specific details of the surgery, such as the type of anesthesia used and the length of the procedure, will depend on the specific gland or glands being removed and the overall health of the patient. After the surgery, patients may need to undergo rehabilitation or follow-up care to manage any side effects or complications.

a client is admitted to a healthcare facility for treatment of chronic obstructive pulmonary disease. which nursing diagnosis is most important for this client?

Answers

Impaired gas exchange related to airflow obstruction.

Chronic obstructive pulmonary disease (COPD) is a progressive lung disease characterized by long-term respiratory symptoms and decreased airflow. The most common symptoms are shortness of breath and a cough that may or may not produce mucus. COPD worsens over time, making daily activities like walking and dressing difficult. While COPD is incurable, it can be avoided and treated.

Tobacco use is the leading cause of COPD. Indoor and outdoor air pollution, including dust, occupational irritants such as grain dust, cadmium dust or fumes, and genetics, such as alpha-1 antitrypsin deficiency, are also risk factors. Common sources of indoor air pollution in developing countries include the use of coal and biomass as fuel for cooking and heating, such as wood and dry dung.
