Restrictive Lung Dysfunction (RLD) =
Definition
problems with getting to FULL lung expansion...


with dyspnea on exertion, persistent, non-productive cough, increased respiratory rate with hypoxemia
Term
Low hematocrit means
Definition
low red blood cell count, meaning possible anemia, possible blood loss, mineral deficiencies
Term
high hematocrit means...
Definition

Term
normal pH in blood is between:
Definition
7.35 and 7.45
Term
Emphysema =

Term
zinc in iontophoresis
Definition
positive, for dermal ulcers and wounds
Term
Stage 0 lymphedema
Definition
no symptoms except one arm feels heavier
Term
Stage 1 lymphedema
Definition
pitting edema that resolves with elevation
Term
Stage 2 lymphedema
Definition
non-pitting and worse swelling that does not resolve with elevation.

some limited tissue damage (permanent but not pervasive)
Term
Stage 3 lymphedema
Definition
the affected limb or area of the body becomes very large and misshapen, and the skin takes on a leathery, wrinkled appearance.
Term
Anterior Approach hip precautions
Definition
no:

ER
Hip Extension
Abd only with assistance (if it's a re-do)
Term
Posterior Approach hip precautions
Definition
No:

IR
Hip flexion past 90 degrees
Adduction beyond neutral
Term
Flexor Pollicis Brevis
Definition
Flexor Pollicis Brevis

The most distal of the thenar muscles.

Attachments: Originates from the tubercle of the trapezium and from the associated flexor retinaculum. Attaches to the base of the proximal phalanx of the thumb.

Actions: Flexes the MCP joint of the thumb.

Innervation: Median nerve.
Term
When to quit or pause cardiac rehabilitation program Phase 1:
Definition
during the walking times - EKG dysrhythmias, shortness of breath, the development of crackles in the lungs where none existed prior to exercise, sharp increases in HR and BP with light activity, onset of syncope, vertigo, and other stress symptoms
Term
normal pulse for older adult
Definition
60-90 bpm
Term
normal temperature for older adult
Definition
96.5-97.5
Term
normal respiratory rate for older adult
Definition
15-22 breaths per min
Term
normal blood pressure for older adult
Definition
90-140/60-90
Term
How much to add to HR during cardiac rehab phase 1:
Definition
Adding 10-20 bpm is appropriate
Term
Normal heard sounds are:
Definition
S1 (mitral and tricuspid valve closing)
s2 (aortic and pulmonic valve closing)
Term
Abnormal heart sounds:
Definition
S3 - heard in early diastole if pt has CHF
