NUR 4090 Exam 1 Questions and All
Correct Answers.
pharmacogenomics - Answer the study of how a person metabolizes medications based on
his or her genetic makeup
when conducting a genetic assessment, the nurse should... - Answer obtain a three-
generation family history
ventilation - Answer the process of bringing in O2 (inhalation)
perfusion - Answer are the tissues receiving oxygenated blood?
-strength of myocardium
-MAP
-patency of the vessels
-circulating volume
shunt - Answer perfusion without ventilation
-blockage in airway (secretions, blood, fluid)
dead space - Answer ventilation without perfusion
-blockage in circulatory system (PE, DVT)
arterial blood gas - Answer measures adequacy of alveolar ventilation
how well the lungs are bringing in O2 and excreting CO2
mixed venous blood gas (SVO2) - Answer measures tissue oxygen delivery
can determine if cardiac output and oxygen delivery is high enough to meet pts demands
drawn from pulmonary catheter
normal pH - Answer 7.35-7.45
normal PO2 (mmHg) - Answer >80 mmHg
normal PCO2 (mmHg) - Answer 35-45
, normal HCO3 (mEq/L) - Answer 22-26
normal SaO2 - Answer >94%
why is venous blood more acidic than arterial blood? - Answer it carries more CO2 (more
waste excreted by the cells)
what does it mean if the SVO2 is greater than 100? - Answer TOO MUCH OXYGEN; needs to
be weaned down
normal SVO2 - Answer 65-75
types of blunt chest trauma (3) - Answer -sternal/rib fractures
-flail chest
-pulmonary contusion
penetrating chest trauma - Answer -gunshot/stab wounds
-pneumothorax
-hemothorax
-cardiac tamponade
-subcutaneous emphysema
s/s rib/sternal fracture - Answer -anterior chest pain
-tenderness
-ecchymosis
-swelling
treatment rib/sternal fracture - Answer -no "real treatment," manage symptoms
-chest binder
-pain relief; PCA pump, ice, analgesia, intercostal nerve block
flail chest - Answer -complication of rib fracture
-3 or more continuous ribs all fractured at 2+ places
-AKA free-floating rib fragments
