B-cells role in infection Correct Answers Arise primarily from
bone marrow
Produce immunoglobins (Igs) that attack antigens. Act as
receptors on B-cells.
-These nonspecific Igs (IgD) are found on the surface of B-cells
-Once pathogen binds to IgDs, the B cells produce specific Igs
that will recognize the particular antigen (aka antibodies)

cardiac output Correct Answers -total volume of blood left
ventricle pumps out per min
-normal= 4-8 L/min

CO=heart rate x stroke volume

cardiac output complications Correct Answers ↓ CO =
↓perfusion to the body

- Diarrhea & vomiting
- Drains (NGT suction)
-Diuretics (thiazide & loop)

2. SIADH (abnormal ADH secretion- regulated water)
3. Adrenal insufficiency (reduced aldosterone)
4. Inadequate sodium intake in diet
5. Kidney Disease
6. HF

Causes of Metabolic Acidosis Correct Answers HCO3 < 22 or
H+ ions elevated

May result from:

, -diabetic ketoacidosis
-diarrhea

Causes of Respiratory Acidosis Correct Answers CO2 >45
mmHg

May result from:
-sleep apnea
-head trauma "knocked out"
- post operative
-CNS depressant drugs (opioids [ morphine, hydromorphone],
alcohol)
-pneumonia (thick mucus buildup results in poor gas exchange)
-COPD or asthma attack

Causes of Respiratory Alkalosis Correct Answers CO2< 35
mmHg

May result from:
Panic attack --> Hyperventilation

Chronic Venous Insufficiency Correct Answers Occurs as a
result of damage to valves in the deep veins of the legs. Valves
may become incompetent as a result of impaired venous return
caused by trauma, central obesity, pregnancy, or prolonged
standing. Valve damage leads to impaired venous return and
abnormally high venous pressure in the venous system, which in
turn leads to pooling and stasis of blood in the lower extremities.
Venous congestion will affect capillary filtration by inhibiting
