Question 11

what is the gate control theory

Answer 11

The Gate Control Theory of Pain is a mechanism, in the spinal cord, in which pain signals can be sent up to the brain to be processed to accentuate the possible perceived pain, or attenuate it at the spinal cord itself. activites such as rubbing can close the gate

severity:
NS response:
vitals:
reason:
pt appearance:
reporting:
behaviour:

Answer 15

ACUTE
- mild to severe
- sympathetic
- increased HR, rr, bp
- diaphoresis, dilated pupils
- restless and anxious
- reports pain

PERSISTENT
- mild to severe
- parasympathetic
- dry warm skin, pupils normal
- beyond healing phase
- distressed and withdrawn

Question 39

2 examples of anticonvulsants

Answer 39

pregab and gabapentin

Question 40

how to anticonvulsants work

Answer 40

modulates NT release by binding to voltage gated calcium channels closes pre synaptic CA channels diminishes excessive neuronal activity and NT release

Question 41

why are antidep often involved in pain management

Answer 41

exert analgesic properties without effecting mood in PP lower dose and shorter delay for pain properties that depressant relief
