Which of the following interventions is MOST effective for a patient who has
Parkinson disease?
1. Use of footprints on the floor for visual cues during gait training
2. Ballistic stretching exercises for the lower extremities
3. Manual perturbations during standing balance activities
4. Trunk flexion exercises to strengthen postural musculature - ANSWERS-
Parkinson disease is characterized by reduced stride length, shuffling steps, and
a festinating gait pattern. The use of footprints on the floor for visual cues
during gait training can help improve foot placement during gait for a patient
who has Parkinson disease
A physical therapist assistant collects data on a patient's sharp-dull sensation.
Two days later, the assistant retests the patient's sharp-dull sensation. Which of
the following terms BEST describes the reliability of these measurements?
1. Parallel forms reliability
2. Internal consistency reliability
3. Interrater reliability
4. Intrarater reliability - ANSWERS-4. Intrarater reliability
The scenario does not demonstrate interrater reliability, because the same
clinician is doing the measurements, rather than different individuals.
4. This scenario demonstrates intrarater reliability, because the same individual
is using the same measurement tool.
Urge incontinence is BEST characterized by which of the following
descriptions?
1. Loss of urine that coincides with increases in intraabdominal pressure
,2. Unexpected and uncontrolled loss of urine
3. Constant leaking of urine from an overdistended bladder
4. Difficulty reaching a toilet in time due to joint or muscle dysfunction -
ANSWERS-2. Unexpected and uncontrolled loss of urine
1. Stress incontinence, not urge incontinence, is best characterized by loss of
urine during activities that increase intraabdominal pressure.
2. Urge incontinence is the sudden unexpected urge to urinate and the
uncontrolled loss of urine.
3. Overflow incontinence, not urge incontinence, is the constant leaking of urine
from a bladder that is full but unable to empty.
4. Functional incontinence, not urge incontinence, is best characterized as
difficulty reaching a toilet in time due to joint or muscle dysfunction.
A 16-year-old patient reports developing pain in the shoulders after a 3-year
history of athletic competitions that required repetitive use of the arm in a
movement pattern of lateral (external) rotation and horizontal abduction. Which
of the following impairments is MOST consistent with the patient's mechanism
of injury?
1. Weakness of the deltoid muscle
2. Anterior glenohumeral joint instability
3. Anterior glenohumeral joint hypomobility
4. Weakness of the latissimus dorsi muscle - ANSWERS-2. Anterior
glenohumeral joint instability
2. Anterior instability occurs when the abducted shoulder is repetitively placed
in a position of lateral (external) rotation and horizontal abduction, as occurs in
competitive swimming or various other sports. This can often lead to recurrent
subluxations of the shoulder and ultimately to osteoarthritis or a torn rotator
cuff.
, A patient who has an infected Stage 4 medial malleolar pressure injury is being
treated with a comprehensive wound care program. Which of the following
interventions is MOST appropriate?
1. Low-amplitude direct current stimulation with positive polarity
2. High-voltage pulsed current electrical stimulation with positive polarity
3. Low-amplitude direct current stimulation with negative polarity
4. High-voltage pulsed current electrical stimulation with negative polarity -
ANSWERS-4. High-voltage pulsed current electrical stimulation with negative
polarity
1. Low-amplitude direct current is used for transdermal drug delivery via
iontophoresis (p. 274). Direct current can cause chemical effects that are caustic
and could damage tissue (p. 231). This would not be appropriate for wound
healing. The positive electrode is most effective to promote healing of a clean
wound in the proliferative phase; however, the wound in this scenario is an
infected wound and would require a negative polarity (p. 277).
2. High-voltage pulsed current stimulates tissue healing via migration of cells to
the treatment area (p. 271). The positive electrode is most effective to promote
healing of a clean wound in the proliferative phase; however, the wound in this
scenario is an infected wound and would require a negative polarity (p. 277).
3. Low-amplitude direct current is used for transdermal drug delivery via
iontophoresis (p. 274). Direct current can cause chemical effects that are caustic
and could damage tissue (p. 231). This would not be appropriate for wound
healing.
4. High-voltage pulsed current can stimulate tissue healing via galvanotaxis,
which results in migration of certain cells to the treatment area based on polarity
(p. 271). The negative electrode is recommended when infection is present (p.
277).
To perform postural drainage to the superior segment of the left lower lobe of a
patient's lungs, the patient should be in which of the following positions?
