DISORDERS QUESTIONS WITH 100%
ACCURATE ANSWERS
what are four clinical characteristics of anemia? - Accurate answers tachycardia (due to
hypoxemia), pallor, dyspnea, and fatigue
which RBC indices measures the average size of red blood cells? - Accurate answers mean
corpuscular volume (MCV)
anemia can be caused by ______, ______, and ______. - Accurate answers excessive blood loss,
impaired RBC production, and increased RBC destruction
which anemia is considered a microcytic anemia? - Accurate answers iron-deficiency anemia
definition of anemia - Accurate answers Anemia is a hematological disorder characterized by a
reduction in the total number of circulating red blood cells (RBCs) and/or a decrease in hemoglobin (Hb)
amount or function.
Complete blood count (CBC) components that relate to RBCs and their production - Accurate answers
microcytic anemia - Accurate answers MCV<80 fL
- RBCs are small
- iron-deficiency anemia
- sideroblastic anemia
- thalassemia
- anemia of chronic disease
normocytic anemia - Accurate answers MCV 80-99 fL
- RBCs are normal in size
- anemia of inflammation and chronic disease
- hereditary spherocytosis
- G6PD deficiency
- paroxysmal nocturnal hemoglobinuria
macrocytic anemia - Accurate answers MCV > 100 fL
- RBCs are large
- B12 deficiency (pernicious anemia)
- folate deficiency
, hypochromic anemia - Accurate answers low MCHC
- RBCs have less hemoglobin than normal
- RBCs appear pale in color
normochromic - Accurate answers normal MCHC
- RBCs have a normal amount of hemoglobin
- RBCs appear neither pale nor dark
hyperchromic - Accurate answers high MCHC
- RBCs have more hemoglobin than normal
- RBCs appear a deeper hue of red than normal
clinical manifestations of anemia - Accurate answers - severe fatigue
- pallor
- weakness
- dyspnea
- dizziness
Furthermore, the reduction in RBC level will decrease blood volume, activating the renin-angiotensin-
aldosterone (RAA) system, which promotes fluid retention and movement of interstitial fluid into the
capillaries. This will not only increase plasma volume, but also dilute the plasma further. The dilute
blood flows faster, which creates a hyperdynamic state. This "stresses" the cardiac system and can result
in tachycardia or even heart failure.
the terms normocytic, microcytic, and macrocytic characterizes red blood cells by their _______. -
Accurate answers size
Terms that end with "-cytic" refer to cell size.
what symptoms reflect decreased tissue oxygenation as an effect of anemia? - Accurate answers
weakness, hypertension, fever, dizziness, and dyspnea
true or false:
identification of the type of anemia involves an exemption of size of the red blood cell only. - Accurate
answers false
Determining both the size and color of RBCs is an important step in identifying the type and source of
anemia.
which anemia is a type of macrocytic anemia? - Accurate answers vitamin B12 deficiency
(pernicious anemia)
which lab value indicates the patient's iron stores are depleted? - Accurate answers ferritin level
A low ferritin level indicates that the patient's iron stores are depleted.
which anemias can be categorized as microcytic-hypochromic? - Accurate answers iron-deficiency
anemia, sideroblastic anemia, and anemia of inflammation and chronic disease
what is the most common type of anemia? - Accurate answers iron-deficiency anemia
IDA is the most common type of anemia worldwide.
