EXAM 3 NURS 155 KEY CONCEPTS AND
INTERVENTION EXAM STUDY GUIDE WITH
SOLUTIONS
What are the benefits of early ambulation after
injury, illness, or surgery? - answer-Promotes
muscle strength, retains joint flexibility, minimizes
joint pain and stiffness, and arrests bone
reabsorption.
What type of exercise involves active movement with
constant muscle contraction? - answer-Isotonic
exercise, such as walking, turning in bed, and self-
feeding.
What is atrophy in the context of immobility? -
answer-Atrophy refers to the wasting or shrinking of
muscles due to inactivity.
What is a contracture? - answer-A contracture is the
permanent fixation of a joint.
,What is disuse osteoporosis? - answer-Disuse
osteoporosis is the loss of bone mass due to lack of
activity, which can lead to pathologic bone fractures.
How quickly can decreased muscle tone occur due to
inactivity? - answer-Decreased muscle tone can
occur within just a few days of inactivity.
What are the effects of immobility on the nervous
system? - answer-Immobility can alter balance,
including proprioception and equilibrium.
What should be done before a patient stands for the
first time after immobility? - answer-The patient
should dangle their legs at the side of the bed.
What happens to lung expansion due to immobility?
- answer-Lung expansion decreases due to body
weight pressure on the rib cage, leading to pooling of
secretions.
What are the potential respiratory complications of
immobility? - answer-Pooling of secretions,
pneumonia, atelectasis, and DVTs.
, What is orthostatic hypotension? - answer-
Orthostatic hypotension is a form of low blood
pressure that occurs when standing after sitting or
lying down.
How does immobility affect the Basal Metabolic Rate
(BMR)? - answer-Immobility leads to a decrease in
BMR, causing the body to break down muscle
protein for energy.
What are common gastrointestinal effects of
immobility? - answer-Decreased appetite, nausea,
and hypomotility of the GI tract leading to
constipation.
What is fecal impaction? - answer-Fecal impaction is
the buildup of hardened feces in the lower intestine
due to unrelieved constipation.
What urinary complications can arise from
immobility? - answer-Urinary stasis, which may
result in UTIs and renal calculi due to inability to
use the bathroom.
