Q

What is the function of red blood cells? ( specifically hemoglobin )

A

Transport oxygen from lungs to the peripheral tissues and carry co2 back to the lungs

Q

Is anemia a specific disease ?
If no? What is it?

A

It isn’t
Instead it’s a symptom of something else that might be going on

Q

Anemia
Integumentary manifestations (3)
And explain why we see each
(2) (1) (1)

A

Pallor
- decrease hemoglobin
- decrease blood flow of the skin

Jaundice
- increase concentration of serum bilirubin

Pruritus ( itching )
- increase serum & skin bile salt concentration

Q

Anemia
Cardiopulmonary manifestations
What does it happen?

And cardic output maintained by what?

A

Results from additional attempts by heart and lungs to provide adequate 02 to the tissues

Cardiac output is maintained by increasing the heart rate & stroke volume

Q

Anemia
Cardiopulmonary manifestations
What might we see? (8)

A

Angina Pectoris ( chest pain ( perfusion problem )
Ascites ( abdominal overflow )
Bruits ( turbulent blood flow over vessel )
Edema
Heart failure
Myocardial infarction
Murmurs ( beating fast heart )
Pulmonary Congestion

16
Q

Why can you suffer from myocardial infarction?

A

Because the severe anemia isn’t supply the cardiac muscles oxygen to pump, so it results in heart attack & even at rest

17
Q

Why do you get ascites in anemia?

A

Because of a fluid shift in the vessels
( since we don’t have enough iron or vitamins in our body )

18
Q

Anemia
Nursing assessment
Subjective data
What should we ask? (4)

A

Past health history
Medications
( especially ones that cause bleeding ; aspirin )
Surgery
Dietary history
( low diet in iron )

19
Q

Additional information
Anemia is found in kids most often because parents will increase their milk more than the food so that?

A

It results in more milk consumption and lack of food being eaten so low iron

20
Q

Anemia
Nursing assessment
Objective data
What would we want to see? (7)
Describe each one as well

A

General
Integumentary
( pallor )
Respiratory
(RR -^)
Cardiovascular
(Heart rate -^)
Gastrointestinal
( GI bleeding )
Neurological
( numbness & dizziness)
Diagnostic findings
( review labs )

21
Q

What is the nursing diagnosis of anemia? (3)

A

Fatigue
Imbalances nutrition
Ineffective self health management

22
Q

What is the goals/outcomes of anemia? (3)

A

Assume normal activities
Maintain adequate nutrition
Develops no complications related to anemia

23
Q

Anemia
Gerontologic considerations
What should we look out for with the elderly?

A

Signs and symptoms may go unrecognized & may be mistaken for normal aging

24
Q

What are the 3 1/3 related to gerontological considerations of anemia ?

A

1/3 related to poor nutrition
1/3 related to chronic disease
1/3 unexplained

25
Erythrocyte production ( RBC ) What is the life span of RBC?
120 days ( about 4 months )
26
Erythrocyte production ( RBC ) What are the 3 alterations in erythropoiesis may decrease RBC production?
Decreased hemoglobin synthesis ( not making enough RBC ) Defective DNA synthesis in RBC ( not effective RBC ) Diminished availability of erythrocyte precursors ( not having building blocks to make )
27
Anemia Decreased erythrocytes production What is erythropoietin(EPO) produced and where is it produced?? % of what in where?
It is glycoprotein Produced in the kidneys (10% in the liver )
28
If our patient has kidney or renal disease they may have what? Why?
Decreased erythropoietin production Since it’s 90% made in the kidneys
29
Normally the amount of red blood cells we produce and the amount of red blood cells that we lose match? True or false
True
30
When we’re having anemia, our body will increase what? And why does it do this?
Increase erythropoietin ( which is a building block for RBC ) in order to increase red cells production
31
When having anemia our body will also increase what type of cells in order to help RBC production?
Stem cells
32
During anemia as well, our body will do what in order to mature RBC in the bone marrow?
Shorten the time of how long it takes to mature RBC ( speed up maturation )
33
What are the 3 types of anemia?
Iron deficiency Megalobastic anemia Blood loss
34
Using the chart in the slideshow Tell me the etiology of what the morphology is telling us? Normocytic; normal size Normochromic; normal color MCV, MCH normal Microcytic, Hypochromic MCV low, MCH low Macrocytic, Normochromic
Acute blood loss, chronic disease, poor nutrition, pregnancy, sickle cell Definitely, iron, B12, lead poisoning B12 deficiency, folic acid, liver disease
