Q

Mild states of anemia are between __________ g/dL and can exist without causing symptoms.

A

10-12 Hgb g/dL.

If symptoms develop, it is because the patient has an underlying disease or is experiencing a compensatory response to heavy exercise. Symptoms include mild fatigue, palpitations, and dyspnea

Q

integumentary manifestations of anemia

A

pallor, jaundice, pruritus

Pallor from reduced amounts of hemoglobin and reduced blood flow to the skin

17
Q

Cardiopulmonary manifestations of anemia

A

manifestations result from additional attempts by the heart and lungs to provide adequate amounts of O2 to the tissues

CO is maintained by increasing the HR and stroke volume
low viscosity of the blood contributes to the development of systolic murmurs and bruits

Heart failure, cardiomegaly, pulmonary and systemic congestion, ascites and peripheral edema may develop if the heart is overworked for an extended period

18
Q

in a severely anemic patient, the nurse would expect to find

A

dyspnea & tachycardia
