Q

Treatment of anemia

A

Iron Supplementation
Ferrous sulfate oral
Iron dextrin IM or IV
if administering IM route, use the Z-track method in order to prevent leakage of the medication into the subcutaneous tissue

Z-track a technique in which the provider slightly pulls and holds pressure on the skin when giving an injection, which leaves a zigzag path behind when they remove the needle and release the skin.

Q

Teaching anemia

A

Increase consumption of iron rich foods
Green vegetables, meat, raisins and iron-fortified foods
Vitamin C improves absorption of iron and calcium-rich products will decrease absorption of iron.
Give iron supplementation with orange juice and not with milk or antacids
Use a straw and brush teeth following administration in order to avoid stained teeth (if taking iron supplement in a liquid form)

Iron supplementation will cause green or black tarry stools, this is expected - nothing to worry about

Q

Polycythemia

A

Rare blood disorder, causes an increase in red blood cells. We have primary polycythemia and secondary polycythemia

Primary polycthemia: caused by a gene mutation that results in uncontrolled production of abdominal red blood cells, this makes the patients blood thicker which puts them at risk for clots, it also impaired blood flow so the patient is at risk for ischemia

Secondary polycythemia, this is due to long-term poor oxygenation that can be caused by a lung disorder or a heart disorder. the body will try to compensate for this poor oxygenation by increasing production off red blood cells

Q

Thrombocytopenia Causes

A

Thrombocytopenia means you have fewer than 150,000 platelets per microliter of circulating blood.

Thrombocytopenia rarely is inherited; or it can be caused by a number of medications or conditions.
Whatever the cause, circulating platelets are reduced by one or more of the following processes: trapping of platelets in the spleen, decreased platelet production or increased destruction of platelets.

Q

Myelodysplastic Syndrome

A

Myelodysplastic syndromes are a group of disorders caused by blood cells that are poorly formed or don’t work properly. Myelodysplastic syndromes result from something amiss in the spongy material inside your bones where blood cells are made (bone marrow).

In a healthy person, bone marrow makes new, immature blood cells that mature over time. Myelodysplastic syndromes occur when something disrupts this process so that the blood cells don’t mature.

Q

Difference Between Hodgkins lymphoma and non Hodgkins lymphoma

A

Both Hodgkin’s lymphoma and non-Hodgkin’s lymphoma are types of lymphoma. Lymphoma is a type of cancer that begins in white blood cells called lymphocytes. Lymphocytes are an important part of the body’s germ-fighting immune system.

The main difference between Hodgkin’s lymphoma and non-Hodgkin’s lymphoma is in the specific lymphocyte each involves

If a specific type of cell called a Reed-Sternberg cell is seen, the lymphoma is classified as Hodgkin’s. If the Reed-Sternberg cell is not present, the lymphoma is classified as non-Hodgkin’s.

Q

Oncological/Cancer

A

Cancer is a disease characterized by DNA damage that causes abnormal cell growth and development

56
Q

Cancer Pathophysiology

A

Three processes: initiation, promotion then progression
During initiation damage or mutation to DNA causes excessive cell division
This is due to excessive oncogene function but decreased suppressor gene function

Promotion: Mutated cells are exposed to promoters that enhance their growth , estrogen is an example of a promoter that will promote the further development of certain types of cancer

Progression: Tumor cells afire additional mutations and their growth rate increases, this allows them to metastasize so basically spread throughout the body and makes them resistant to therapy

57
Q

Cancer Risk factors

A

Older age
Genetics
Immunosupression
Viruses
Smoking

69
Q

Rh Negative

A

Rh factor is an inherited protein found on the surface of red blood cells. If your blood has the protein, you’re Rh positive. If your blood doesn’t have the protein, you’re Rh negative. The “+” or “–” you might see after your blood type refers to Rh positive or Rh negative.
Rh positive is much more common than Rh negative. Having an Rh negative blood type is not an illness, and it usually does not affect your health. But it can affect pregnancy.

Your pregnancy needs special care if you’re Rh negative and your baby is Rh positive.

70
Q

RH during pregnancy

A

During pregnancy, problems can happen if you’re Rh negative and your baby is Rh positive. Usually, your blood doesn’t mix with your baby’s blood during pregnancy. However, a small amount of your baby’s blood could come in contact with your blood when the baby is born. It can also happen if you have bleeding or trauma to your abdomen during pregnancy.

If you’re Rh negative and your baby is Rh positive, your body might produce proteins called Rh antibodies if your blood and the baby’s blood mix. Those antibodies aren’t a problem during the first pregnancy. But problems can happen if you become pregnant again.

If your next baby is Rh positive, the Rh antibodies can cross the placenta and damage the baby’s red blood cells. This could lead to life-threatening anemia, a condition in which red blood cells are destroyed faster than the baby’s body can replace them. Red blood cells are needed to carry oxygen throughout the body.

If you’re Rh negative, you might need to have another blood test — called an antibody screen — several times: during your first trimester, during week 28 of pregnancy and when your baby is born. Some people need the test more often.

71
Q

Monoucleosis

A

Infectious mononucleosis (mono) is often called the kissing disease. The virus that causes mono (Epstein-Barr virus) is spread through saliva. You can get it through kissing, but you can also be exposed by sharing a glass or food utensils with someone who has mono.

72
Q

Mononucleosis Signs and Symptoms

A

Fatigue
Sore throat
Fever
Swollen Lymph nodes
Swollen tonsils
Headache
Skin rash
Swollen spleen

The virus has an incubation period of about four to six weeks, although in young children this period may be shorter. The incubation period refers to how long before your symptoms appear after being exposed to the virus. Signs and symptoms such as a fever and sore throat usually lessen within a couple of weeks. But fatigue, enlarged lymph nodes and a swollen spleen may last for a few weeks longer.

73
Q

Mononucleosis Complications

A

Enlarged spleen
Liver issues: hepatitis, Jaundice

74
Q

Hashimotos

A

Hashimoto’s disease is an autoimmune disorder affecting the thyroid gland.
Hashimoto’s disease, immune-system cells lead to the death of the thyroid’s hormone-producing cells. The disease usually results in a decline in hormone production (hypothyroidism).

Although anyone can develop Hashimoto’s disease, it’s most common among middle-aged women. The primary treatment is thyroid hormone replacement.

75
Q

Hashimotos Signs and Symptoms

A

Fatigue and sluggishness
Increased sleepiness
Dry skin
Constipation
Muscle weakness
Irregular or excessive menstrual bleeding
Depression
Problems with memory or concentration
A puffy face
Brittle nails

76
Q

Raynaud’s

A

rare vascular disorder that causes vasospasming of the arteries in the fingers and/or toes. Decreased blood flow to these extremities

Primary raynauds: Raynauds disease, cause is idiopathic. More common and symptoms tend to be a little less severe

Secondary Raynauds: raynauds phenomenon, underlying connective tissue disease such as lupus or scleroderma which damages the arteries

77
Q

Raynaud’s Signs and symptoms

A

Upon exposure to cold or stress, the fingers will become cyanotic, cold, painful and numb. after spasming, blood flow will return to the area and cause those fingers to turn very red in colour

78
Q

Raynauds signs and symptoms

A

Diagnosis can usually be done based on the clinical signs and symptoms
ANA titer: anti-nuclear antibody titer to assess for the presence of any underlying autoimmune disorders in the patient

79
Q

Raynauds Treatment

A

Use of vasodilators and then for severe cases of raynauds = sympathectomy

80
Q

Raynauds Patient teaching

A

Avoid cold, dress warmly
Cold can trigger the vasospasming associated with raynauds
Decrease caffeine intake because that causes vasoconstriction
Reduce stress levels and stop smoking

81
Q

Sickle Cell Anemia

A

Autosomal recessive genetic disorder that causes chronic anemia, pain, infection as well as organ damage

82
Q

Sickle Cell Anemia Pathophysiology

A

Normal hemoglobin (Hba) replaced with abnormal sickle hemoglobin (Hbs) and this causes the sickling of the red blood cells
Normally red blood cells are nice ad round, when we have the sickling they turn into a C shape and can easily get caught in the blood vessels which obstructs blood flow to the organs and can result in tissue hypoxia.

83
Q

Sickle cell anemia Risk factors

A

family history is going to be a risk factor because this is a genetic disorder
African Americans and middle Eastern descent are at higher risk for sickle cell anemia

84
Q

Diagnosis of Sickle cell anemia

A

Sickle turbidity test, detects abnormal hemoglobin
Hemoglobin electrophoresis

85
Q

Sickle cell treatment

A

Opioid analgesics on a schedule
Provide antibiotics if there is an infection present
Administer IV fluids to help decrease the viscosity of the blood - help the flow of blood get to the organs that will help prevent tissue hypoxia
Give blood products and oxygen as ordered

86
Q

Sickle cell anemia Pt teaching

A

Encourage our patient to get enough fluid intake to help prevent dehydration and prevent the onset of a vast-occulsive crisis. We want them to avoid getting infection so they need to perform meticulous hand hygiene and avoid crowds
