CNUR 103 KEY CONCEPTS AND
REVISION NOTES
◉ respiration
Answer: delivery of 02 to cells and removal of CO2
◉ What is FiO2
Answer: fraction of inspired oxygen
◉ Normal atmospheric FiO2
Answer: 21% or 0.21
◉ Emesis
Answer: vomiting
◉ hyperglycemias
Answer: high blood sugar
◉ hypoglycemia
Answer: low blood sugar
◉ Peripheral neuropathy
, Answer: nerve damage causing numbness, tingling, burning and
pain in peripheral aspects i.e. limbs
◉ Peripheral vascular disease
Answer: narrowed or blocked blood vessels reduce blood
circulation to limbs (usually legs)
◉ Syncope
Answer: temporary loss of consciousness, caused by sudden blood
flow to the brain
◉ Thromboembolic disease
Answer: blood clots forming in vessels that break off and travel,
causing dangerous obstructions
◉ antiemetics
Answer: medications that prevent vomiting
◉ hypoxia
Answer: tissues are deprived of adequate oxygen, causing
shortness of breath, confusion, rapid heart rate and cyanotic skin
◉ Primary intention wound healing - initial phase
Answer: - edges approximated (lined up)
- epithelial cells come to the wound
