Module 4 &5 - General survey, measurement and vital signs, pain assessment Flashcards
The Doppler technique
The Doppler technique can be used to locate peripheral pulse sites and, for blood pressure measurement, to augment Korotkoff’s sounds.
A common error in blood pressure measurement includes
Waiting less than 1 to 2 minutes before repeating the blood pressure reading on the same arm will result in a falsely high diastolic pressure related to venous congestion in the forearm.
The tympanic membrane thermometer
provides an accurate measurement of core body temperature.
Endogenous obesity is
Endogenous obesity is caused by either the administration of ACTH or excessive production of ACTH by the pituitary.
Neuropathic pain implies an abnormal
processing of the pain message.
What is the source of deep somatic pain?
Deep somatic pain comes from such sources as joints, tendons, muscles, and bones.
Transduction
first phase of nociceptive pain. During this phase injured tissue releases chemicals that propagate the pain message, generating an action potential that moves along an afferent fibre to the spinal cord
Transmission
The second phase where the pain impulse moves from the level of the spinal cord to the prain
Perception
Third pain, the person has conscious awareness of a painful sensation
Modulation
the fourth phase of nociceptive pain, neurons from the brain stem release neurotransmitters that slow down or impede the pain impulse
