Research and Evidence-Based Practice Part One Flashcards
purpose of analysis of variance (ANOVA)
to determine if there is a difference between three or more groups
purpose of the glomerulus
filtration of blood
examples of dependent variables in PT
ROM
pain
BP
what kinds of burns are generally indicated for surgery
full-thickness
failure to reject the null hypothesis indicates
no significant difference between groups or treatments
what is specificity
someone will test negative for a condition they DO NOT have
purpose of t-test
to see if there is a difference between two groups
purpose of chi-square test
tells the researcher whether the observed pattern is different than what would have been expected by chance aloen
what is residual volume
volume of gas remaining in the lungs at the end of end of a maximal expiration
what is reliability
consistency of measuring device or procedure
what is validity
the extent at which something accurately measures what it’s supposed to
what is tidal volume
amount of air inspired and expired with each breath during quiet breathing
a pressure above 15 ppsi for pulsatile lavage for debridement could…
push bacteria further into the wound
what is sensitivity
someone will test positive for a condition they actually have
best PSI for pulsatile lavage
4-15 ppsi
what lung volume is most different between males and females
inspiratory reserve volume
full-thickness burns characteristics
dry, firm, leathery ESCHAR
eschar has no pliability and is insensate to touch
difference between intra and intertester reliability
inter - two or more different testers
intra - one tester
examples of independent variables in PT
type of treatment
frequency of visits
intervention time
purpose of pulsatile lavage
suctioning to cleanse and debride wounds
purpose of renal pelvis
drainage of kidney into the ureter
what does it mean to reject the null hypothesis
a significant difference was observed between groups or treatments
