3. Introduction
Anemia is one of the most underdiagnosed conditions
and, if left untreated, can have many serious
implications such as cardiovascular disease and
compromised immune functions
4. Introduction
According to WHO estimates, India is one of the
countries in the world that has highest prevalence of
anemia.
The bliss of motherhood thrives under the looming
presence of anemia in India.
5. Definition
Anaemia ( from Greek word anaimia, meaning lack
of blood)
is a decrease in number of red blood cells (RBCs) or
less than the normal quantity of hemoglobin in the
blood.
8. Anemia cases in India on rise: NFHS 3
report
Adolescence in India goes hand in hand with iron-deficiency
anemia, medically known as IDA
While 56 % of adolescent girls are anemic, boys too are falling
prey to the disease. Around 30 % of adolescent boys are
suffering from anemia.
The Hb count in most of the adolescent girls in India is less
than the standard 12 g/decilitre, the standard accepted
worldwide.
the disease troubles 59 % cases of pregnancy while 63 %of
lactating women are anemic. States like Bihar and Rajasthan
register 60 % of pregnant women to be anemic.

10. Red blood cell
cytoplasm is rich in Hb
mature red blood cells are flexible biconcave disks
that lack a cell nucleus
2.4 million new erythrocytes are produced per
second.
develop in the bone marrow and circulate for about
100–120 days in the body before their components
are recycled by macrophages.
11. RBC
women have about 4 to 5 million erythrocytes per
microliter (cubic millimeter) of blood and
men about 5 to 6 million;
people living at high altitudes with low oxygen
tension will have more
Each RBC contains approx. 270 million of Hb
biomolecules, each carrying 4 heme groups.
RBCs of an average adult human male store
collectively about 2.5 grams of iron, representing
about 65% of the total iron contained in the body
14. Just for GK……..
Do u
know????
The only known vertebrates
without RBC are the crocodile
icefishes .
They live in very oxygen rich cold
water and transport oxygen freely
dissolved in their blood.
17. Immature RBC
about 1% of the red cells
develop and mature in the red bone marrow
then circulate for about a day in the blood stream
before developing into mature red blood cells.
do not have a cell nucleus.

23. The burden of anemia among women in India
M E Bentleyand P L Griffiths
Objective: to investigate the prevalence and determinants of
anemia among women in Andhra Pradesh.
Subjects:A total of 4032 ever-married women aged 15–49 from
3872 households.
Results:In all 32.4% of women had mild ,14.19% had moderate ,
and 2.2% had severe anemia . Protective factors include Muslim
religion, reported consumption of alcohol or pulses, and high
socioeconomic status, particularly in urban areas. Poor urban
women had the highest rates and odds of being anemic. Fifty-two
percent of thin, 50% of normal BMI, and 41% of overweight
women were anemic.
Conclusion:New program strategies are needed, particularly those
that improve the overall nutrition status of women of reproductive
ages. This will require tailored programs across socio-economic
groups and within both rural and urban areas, but particularly
among the urban and rural poor.
25. Causes
• Iron deficiency
anemia
• Anemia of chronic
disease
• Anemia from active
bleeding
Anemia related to
pregnancy
Anemia related to
poor nutrition
Pernicious Anemia
Sickle cell anemia:
Thalassemia
Alcoholism
Bone marrow-related
anemia
Aplastic anemia
Hemolytic anemia
Anemia related to
medications
27. Classification
If the cells are smaller than normal (under 80 fl), the
anemia is said to be microcytic;
if they are normal size (80–100 fl), normocytic;
if they are larger than normal (over 100 fl), the
anemia is classified as macrocytic.
29. Iron deficiency anemia
Iron is an essential part of Hb
low iron levels result in decreased incorporation of
hemoglobin into red blood cells
hypochromic (paler than usual) and microcytic
(smaller than usual)
Causes
insufficient dietary intake
absorption of Iron
losses due to diseases.
bleeding lesions of the gastrointestinal tract
parasitic infestation
30.
31. Anemia of chronic diseases
Any long-term medical condition .
The exact mechanism of this process in unknown,
chronic infection or a cancer
people with chronic (long-standing) kidney disease.
32. Anemia of chronic diseases
crohn’s
disease
SLE
rheumatoid
arthritis,
ulcerative
colitis
Cancer Long-term
infections,
Liver
cirrhosis
CKD
35. Macrocytic anemia
Megaloblastic anemia, the most common cause of
macrocytic anemia
due to a deficiency of either vitamin B12, folic acid (or
both).
Causes
gastric bypass surgery
Hypothyroidism
Alcoholism
Drugs that affect DNA
Leukemia
The anticonvulsant drug dilantin
36. Normocytic anemia
overall hemoglobin levels are decreased,
but the red blood cell size(MCV) remains normal.
Causes
Acute blood loss
Anemia of chronic disease
Hemolytic anemia
Aplastic anemia
37. Aplastic anemia
decrease in or damage to marrow stem cells, damage to
the microenvironment within the marrow, and
replacement of the marrow with fat.
It results in bone marrow aplasia (markedly reduced
hematopoiesis)
CAUSES
congenital or acquired
Idiopathic
Infections and pregnancy
certain medications, chemicals,
or radiation damage
41. Sickle cell anemia
autosomal recessive
RBC that assume an abnormal, rigid, sickle shape
Sickling decreases the cells' flexibility and results in a
risk of various complications.
The sickling occurs because of a mutation in the
hemoglobin gene
53. the signs that may indicate anemia
Change in stool color
rapid heart rate
low blood pressure
rapid breathing
pale or cold skin
yellow skin called jaundice if anemia is due to red blood
cell breakdown
heart murmur
enlargement of the spleen with certain causes of anemia
61. NURSING DIAGNOSES
Activity intolerance related to weakness, fatigue, and
general malaise
Imbalanced nutrition, less than body requirements,
related to inadequate intake of essential nutrients
Ineffective tissue perfusion related to inadequate
blood volume or HCT
Noncompliance with prescribed therapy
62. Nursing Interventions
MANAGING FATIGUE
Assist the patient to prioritize activities and to
establish a balance between activity and rest that is
realistic and feasible from the patient’s perspective.
Patients with chronic anemia need to maintain some
physical activity and exercise to prevent the
deconditioning that results from inactivity.
63. Nursing Interventions
MAINTAINING ADEQUATE NUTRITION
A healthy diet should be encouraged.
Because alcohol interferes with the utilization of
essential nutrients, the nurse should advise the patient
to avoid alcoholic beverages or to limit their intake
and should provide the rationale for this
recommendation.
Dietary teaching sessions should be individualized,
including cultural aspects related to food preferences
and food preparation.
64. Nursing Interventions
MAINTAINING ADEQUATE PERFUSION
Lost volume is replaced with transfusions or intravenous
fluids, based on the symptoms and the laboratory
findings.
Supplemental oxygen may be necessary, but it is rarely
needed on a long-term basis unless there is underlying
severe cardiac or pulmonary disease as well.
The nurse monitors vital signs closely;
other medications, such as antihypertensive agents, may
need to be adjusted or withheld.
65. Nursing Interventions
PROMOTING COMPLIANCE WITH PRESCRIBED
THERAPY
Patients need to understand the purpose of the
medication, how to take the medication and over what
time period, and how to manage any side effects of
therapy.
To enhance compliance, the nurse can assist patients
in developing ways to incorporate the therapeutic
plan into their lives, rather than merely giving the
patient a list of instructions.
66. PATIENT EDUCATION
Taking Iron Supplements
Take iron on an empty stomach (1 hour before or 2 hours
after a meal).
Start with only one tablet per day for a few days, then
increase to two tablets per day, then three tablets per day
Increase the intake of vitamin C (citrus fruits and juices,
strawberries,tomatoes, broccoli), to enhance iron
absorption.
Eat foods high in fiber to minimize problems with
constipation.
Remember that stools will become dark in color.
67. Nursing Interventions
MONITORING AND MANAGING POTENTIAL
COMPLICATIONS
assessfor signs and symptoms of heart failure.
A serial record of body weights can be more useful than a
record of dietary intake and output, because the intake
and output measurements may not be accurate.
In the case of fluid retention resulting from congestive
heart failure, diuretics may be required.
In megaloblastic forms of anemia, the significant
potential complications are neurologic.
A neurologic assessment should be performed for patients
with known or suspected megaloblastic anemia.
68. Nursing Interventions
Measure temperature of bath water with thermometer
because anemia may cause poor circulation.
Provide blankets and warm clothing to increase
comfort and aid circulation.
Notify physician if excessive vomiting, coughing or
straining at stools occurs so that medication can be
prescribed to alleviate symptom.
Avoid aspirin-containing products to prevent
bleeding.
Avoid forceful blowing.
69. Nursing Interventions
Avoid contact on gingival when brushing and flossing
teeth.
Avoid situations in which trauma may occur, such as
shaving with straight-edge razor, ambulating after
taking medication that may cause orthostasis, or using
sharp utensils
Avoid purseful sexual intercourse and use adequate
lubrication.
70. Nursing Interventions
Use of stool softeners or laxative to avoid PRN to
avoid straining.
Ascorbic acid (Vitamin C) promotes iron absorption,
thus iron preparations should be taken with orange
juice.
Bowel movements will be black from excess iron
excretion.
Iron supplements usually given for at least 6 months
to restore body stores.
71. Nursing interventions
Keep skin clean and bedclothes dry.
Encourage diet high in protein, vitamins, and minerals.
Encourage cool, bland foods; flavored ices and ice cream
are well tolerated.
Monitor Hb/Hct and assess whether other factors (e.g.,
nutritional deficiencies, fluid and electrolyte disorders,
depression, etc.) are contributing to symptomatology.
Assess activity schedule and suggest daily activities that
allow for rest periods.
Transfuse whole blood and packed red blood cells as
ordered by physician.
72. Nursing interventions
Avoid rectal thermometers, suppositories, and
enemas.
Avoid heating pads or hot water bottles.
Iron salts are gastric irritants and should always be
taken following meals.
Iron preparation taken on empty stomach cause
dyspepsia, abdominal discomfort, and diarrhea
Liquid iron preparations should be well diluted and
taken through a straw (undiluted liquid iron stains
teeth).
