2 Questions | 2026/2027 | Answers Correct | With Complete
Solutions
thrombocytopenia
- low platelet count
- fewer than 100,000/uL which can cause bleeding
- can occur from decreased platelet synthesis in bone marrow,
increased sequestering of platelets in spleen, or decreased
platelet life span
thrombocytosis
- excessive number of platelets
- more than 750,000/uL which can cause excessive clotting
- can occur after splenectomy (body unable to eliminate
platelets) or hyperactive bone marrow
thrombopoietin
- stimulate platelet formation
- synthesized by liver
- platelet life span 7-10 days
spleen
- which body structure sequesters and lyses dead platelets?
- "graveyard"
,DVT
- stagnant blood flow cause venous thrombus formation in lower
extremities of immobile, sedentary clients
- it breaks away from the leg vein (femoral) and travels into the
inferior vena cava to the RA to right RV then to pulmonary
artery
- lodges in a pulmonary arterial vessel and blocks circulation
from becoming oxygenated cause pulmonary embolism
- client can be anxious, dizzy, restless, dyspnea, sudden SOB,
chest pain
estrogen
- high levels of this hormone increase hepatic synthesis of
coagulation factors and decreased antithrombotic factors
- creating increased risk for formation of venous thrombus
oral contraceptives
- the incidence of stroke, thromboemboli, myocardial infarction
is greater in women (35+ smokers) who use _?
ventilation
- the process of insipration and expiration of air thorugh the
pulmonary airways
perfusion
- the movement of blood through the pulmonary circulation,
eventually providing oxygen to every part of the body
constrict
, - when there is little ventilation, the pulmonary arterial vessels
will _ to redistribute blood flow to better-ventilated areas of the
lung
ventilation-perfusion
- an imbalance that occurs when air cannot flow into an alveolus
or blood flow around an alveolus is altered
- should be equal or match
- can occur from pulmonary embolism
central chemoreceptors
- sense changes in carbon dioxide and blood pH and cause
alterations in the rate and depth of respirations
- located in medulla
- increase respirations, return pH to normal
peripheral chemoreceptors
- respond to primarily to a decrease in arterial oxygen
- found in aortic arch and bifurcation of carotid artery
hypoxic drive
- main trigger for breathing
- stimulate respirations
- takes over when CO2 accumulation is not stimulating the
medulla to control respiration
atelectasis
- collapse of small number of alveoli resulting in reduced gas
exchange
