MUST know Flashcards
Loose Pack position of Joint
The loose-packed position for the hip joint is 30° of flexion The resting position of the hip is flexion of 30° and abduction of 30°
2. The loose-packed position for the glenohumeral joint is 55° of abduction (Hoogenboom, p. 344). The resting position is abduction of 55° and horizontal adduction of 30°
3. Tibiofemoral joint placed in 25° of flexion will be in the resting or loose-packed position
4. The loose-packed position for the humeroulnar joint is 70° of flexion
gastroesophageal reflux disease- foods to not eat
Modifications to help manage symptoms of gastroesophageal reflux disease includes avoiding eating large meals that can distend the stomach and avoiding items such as chocolate, peppermint, alcohol, caffeinated coffee, and fried and/or fatty foods.
TMJ Mob to improve limitation of Mouth Opening
Distraction with anterior glide to the temporomandibular joint is best for improving a patient’s ability to achieve greater opening of the mouth.
Posterior glide is not the appropriate arthrokinematic motion to assist with mouth opening. Posterior glides are appropriate for improving mouth closing.

Effectiveness is the extent to which an intervention produces a desired outcome under usual clinical conditions.
Effect size
The effect size is the magnitude of the difference between two mean values.
Efficacy
Efficacy is the extent to which an intervention produces a desired outcome under ideal conditions.
required to wear a surgical face mask
- Airborne precautions, including wearing a particulate respirator, should be used when working with patients who have rubeola.
- Particulate respirators are recommended when working with patients who have tuberculosis.
- Airborne precautions, including wearing a particulate respirator, should be used when working with patients who have varicella zoster virus.
- Droplet precautions, including wearing a face mask, should be used when working with patients who have bacterial pneumonia.
M.S & Overflow incontinence caused by an underactive detrusor muscle
- The symptoms fit the description for overflow incontinence. In patients who have multiple sclerosis, overflow incontinence is usually the result of a hypotonic or underactive detrusor muscle.
Stress incontinence caused by
Stress incontinence is due to weak pelvic floor muscles, internal urethral sphincter failure, hypermobility of the ureterovesical junction, or damage to the pudendal nerve and would not be caused by anxiety in a patient who has multiple sclerosis
A patient sustained an injury to the cerebellar cortex. Which of the following functions would MOST likely be diminished?
- Difficulty with initiation of movement occurs in basal ganglia lesions, not cerebellar lesions (p. 195).
- Motor information is processed in the primary motor cortex and is located in the precentral gyrus of the cerebral cortex. Damage to the cerebellum would not be likely to cause diminished strength. (pp. 190-191)
- Sensory information is processed in the primary somatosensory cortex, which is located in the postcentral gyrus of the cerebral cortex. Damage to the cerebellum would not be likely to cause diminished sensation. (pp. 86-87)
- Rapid alternating arm movements test for dysdiadochokinesia, the term used to indicate impaired ability to perform these movements. Patients who have cerebellar lesions would be most likely to experience this impairment. (p. 194)
- Frequency of 35 pps, duration of 50 microseconds
- Frequency of 35 pps, duration of 150 microseconds
- Frequency of 50 pps, duration of 250 microseconds
- Frequency of 150 pps, duration of 50 microseconds
- The lower pulse frequency is appropriate for promoting muscle strength, but the pulse duration is too short and would be more appropriate for pain control
- Frequency of 35 pps and duration of 150 microseconds would be more appropriate for strengthening a small muscle group. The quadriceps are one of the largest muscle groups in the body
- For a large muscle group with intact innervation, the most effective parameters for promoting increased muscle strength are a frequency of 35-80 pps and a pulse duration of 200-350 microseconds
- Frequency of 150 pps and duration of 50 microseconds would be more appropriate for influencing pain and not as effective for promoting muscle strength
An adult patient who reports a new onset of back pain had a radiograph that identified wedging of the L1 vertebral body. Which of the following muscle groups would be MOST appropriate to stretch?
- The symptoms and radiographic bony changes suggest osteoporosis. Compression fractures are commonly associated with trunk flexion, and symptoms are provoked with flexion activities. Stretching of the antagonist muscles, such as the shoulder horizontal adductors and medial (internal) rotators, hip flexors and medial (internal) rotators is recommended for patients who have compression fractures of the vertebral bodies secondary to osteoporosis.
Slipped capital femoral epiphysis
Slipped capital femoral epiphysis generally occurs in adolescents. Symptoms include antalgic gait and pain in the groin, knee, or medial thigh. This disorder is more likely to present with antalgic gait and a laterally (externally) rotated lower extremity. When the onset is acute, the adolescent will be unable to bear weight on the affected extremity. Obesity is often a factor in the development of this condition
Legg-Calvé-Perthes disease
The clinical picture of Legg-Calvé-Perthes disease is a typical occurrence between the ages of 3 to 13 years, most commonly in physically active, yet small, boys. The etiology of the disease is unknown. It is an avascular necrosis that disrupts blood flow to the capital femoral epiphysis, progresses through four well-defined stages, and is ultimately self limiting. Children who have Legg-Calvé-Perthes disease often are smaller in stature and may have limb length discrepancies
Osgood-Schlatter disorder
Osgood-Schlatter disorder is an overuse injury that presents with anterior knee pain. It typically appears between the ages of 9 to 15 years in children who are physically active. The chief symptoms are an ache in the anterior knee and a clear tenderness of the apophysitis upon direct palpation. Muscle contraction will also produce pain. The application of strengthening exercises should not provoke symptoms
Developmental hip dysplasia
Undetected childhood developmental hip dysplasia can result in a form of avascular osteonecrosis as early as adolescence or in adulthood. Symptoms typically are hip or groin pain, gluteus minimus gait, limited hip range of motion for medial (internal) rotation, flexion, and abduction, and tenderness to palpation over the hip joint. The femoral head is the most common site of the disorder. Symptoms, when they appear, may be mild initially and increase over time
Kidney
The kidneys are located in the region of the costovertebral angle. Pain upon percussion of this region is common in kidney involvement. Pain associated with the kidneys usually refers to the ipsilateral flank and groin.
Spleen
. The spleen is located near the left costovertebral angle but not in close association, compared with the kidney. In this case, it is the right side that is involved. Left upper quadrant and left shoulder pain would be associated with injury to the spleen.
Which of the following arthrokinematic motions occurs during open-chain knee flexion?
During open-chain knee flexion, the femur is stationary. According to the concave-convex rule of arthrokinematics, when the concave surface of the tibia is flexing on the convex surface of a fixed femur, the tibia both rolls and glides posteriorly on the relatively fixed femoral condyles.
A patient’s skin distal to the mid-calf is darker than the skin proximal to the mid-calf. Which of the following examination techniques would MOST efficiently screen for the expected dysfunction
1.Capillary refill is a test of surface arterial blood flow and would not provide information about venous insufficiency
2. The patient presents with hemosiderin staining, which is a sign of venous insufficiency. A venous filling time test can indicate that a patient has venous insufficiency if the venous filling time is less than 15 seconds If the test result is positive for venous insufficiency, further testing can be recommended for verification and examination of the extent of the condition.
3. Diminished dorsalis pedis pulse would be expected with arterial insufficiency, not venous insufficiency
4. Sensory filament testing is a test for detecting peripheral sensation, not for venous insufficiency
A patient who has rheumatoid arthritis is referred to a physical therapist for exercise prescription. Which of the following considerations is MOST important when prescribing exercise for the patient?
- Include low-load, prolonged stretching activities.
- Give a low priority to pain as an indicator of exercise tolerance.
- Modify exercise according to the phase of the disease process.
- Increase the duration of exercise while decreasing the frequency.
- Soft tissue structures may be weakened by the rheumatic process, and stretching would increase risk of injury to the tissues
- Fatigue and increased pain should be recognized as indicators of exercise intolerance, and the type and intensity of exercise should be varied depending on symptoms
- The clinician should consider the stage (acute versus chronic) of rheumatoid arthritis when designing an exercise program, and the patient must be taught to modify the program to match the stage of the illness
- Longer duration exercise is incorrect because a principle of joint protection and energy conservation is to use frequent but short episodes of exercise
A patient reports feeling light-headed when moving from sitting to standing position. Which of the following patient instructions would be MOST appropriate?
- Sit down and perform ankle pumps.
- Remain standing with the eyes closed.
- Remain standing with the eyes open.
- Return to supine position and discontinue the session.
- The patient is most likely experiencing orthostatic hypotension. This is due to a rapid change in body position that causes blood to pool in the abdomen and lower extremities because of gravity. The reduction in venous return leads to a reduced stroke volume and cardiac output, resulting in a lowering of blood pressure and feelings of light-headedness. The most appropriate course of action is to have the patient return to sitting position and perform ankle pumps to increase venous return and ultimately increase blood pressure.
- The patient is most likely experiencing orthostatic hypotension. Having the patient remain standing with eyes closed will increase feelings of light-headedness.
- The patient is most likely experiencing orthostatic hypotension. Having the patient remain standing with eyes open will increase feelings of light-headedness.
- The patient is most likely experiencing orthostatic hypotension. Although having the patient return to supine position is a good option; discontinuing therapy session should only occur if sitting and performing ankle pumps does not relieve the symptoms.
During an examination, a physical therapist observes that a patient has difficulty concentrating, refuses to participate in certain examination procedures, and appears reactive and fearful to touch. Which of the following strategies would be MOST appropriate during screening of the patient?
- Ask direct questions about substance abuse.
- Ask indirect questions about substance abuse.
- Ask direct questions about violence or abuse.
- Ask indirect questions about violence and abuse.
- An individual with a substance use disorder may have cognitive impairments that affect judgment and impulse control as well as demonstrate mood swings, social withdrawal, and belligerent or confrontational interactions. Indications of substance abuse warrant discussion with the patient and referral to either a physician or mental health professional. The behaviors of the patient described in the clinical scenario do not correlate with behavior indicative of suspected substance abuse. (pp. 104-105)
- An individual with a substance use disorder may have cognitive impairments that affect judgment and impulse control as well as demonstrate mood swings, social withdrawal, and belligerent or confrontational interactions. Indications of substance abuse warrant discussion with the patient and referral to either a physician or mental health professional. The behaviors of the patient described in the clinical scenario do not correlate with behavior indicative of suspected substance abuse. (pp. 104-105)
- Asking direct questions about violence during routine social screening and safety questions is recommended. The therapist may suspect violence or abuse if a patient has injuries to the head and trunk (areas usually out of sight), lacerations, fractures, contusions, and/or black eyes. Burns, knife wounds, and joint injuries are also common. Victims of violence and abuse may appear excessively reactive and fearful of touch. Patients may use vague descriptions of pain and mechanism of injury, and even appear evasive. Patients may confide in health care providers that they feel isolated or alone. (p. 43)
- Asking direct questions about violence during routine social screening and safety questions is recommended. It is essential to establish a safe environment where the therapist can open a dialogue with the client, listen carefully, and document conversations. Good communication skills are of the utmost importance to develop rapport and a sense of trust. (p. 43)
A physical therapist is educating a patient on the use of a moist hot pack for home treatment. For the patient to prevent burns and still receive the benefits of superficial heat, which of the following heat application time frames is MOST appropriate?
- 5-10 minutes
- 20-30 minutes
- 45-60 minutes
- 70-90 minutes
- Five to 10 minutes is an insufficient amount of time for therapeutic heating effects.
- The ideal amount of time for therapeutic heating effects varies from 15-30 minutes.
- Forty-five to 60 minutes is too long a period of time and could increase the risk of developing a burn.
- Seventy to 90 minutes is too long and could increase the risk of developing a burn.
Which of the following clinical manifestations would MOST likely be associated with right ventricular failure?
- Pulmonary edema
- Jugular venous distention
- Paroxysmal nocturnal dyspnea
- Muscular weakness and fatigue
- Pulmonary edema is most associated with left ventricular failure (pp. 592-593).
- In patients who have right ventricular failure, the right side of the heart is unable to adequately pump fluid through the pulmonic valve. This fluid backs up into the jugular vein through the superior vena cava. (pp. 593-595)
- Inability of the left ventricle to adequately distribute oxygenated blood through the body may result in disruptions in mechanisms of respiratory control (p. 593).
- Insufficient cardiac output to working muscles by the left ventricle may result in tissue hypoxia and inability to remove metabolic waste (p. 593).
Which of the following interventions is MOST appropriate for a 12-year-old child who has a history of progressive idiopathic scoliosis and a Cobb angle of 45°?
- Orthotic management
- Postural correction
- Surgical intervention
- Spinal stabilization exercises
- Orthotic management is typically indicated for children who have idiopathic scoliosis and who are skeletally immature and have a Cobb angle of 25° to 45°.
- Postural correction is not sufficient to manage a curve of 45°.
- The major indication for spinal fusion is a documented, progressive idiopathic curve and a Cobb angle greater than 40°.
- Exercise alone is not sufficient to manage a curve of 45°.
When conducting a 10-meter walk test, appropriate procedure includes which of the following elements?
- The patient is permitted to use an assistive device.
- The patient is instructed to walk with feet heel-to-toe.
- The patient begins the assessment in a seated position.
- The patient walks until reaching a marker, then turns around.
- Assistive devices are permitted and should be used for safety if the patient usually uses one.
- The test should be conducted with the patient using the patient’s usual walking pattern.
- The seated position is the beginning position for the Timed Up and Go test, not an assessment of gait speed. For the 10-meter walk test, the timing starts when the patient reaches the first marker of the 10-meter walk test.
- This option describes a condition of the Timed Up and Go test. Gait speed should not include the time it takes for a patient to turn around. Gait speed should be measured over a straight course.
A family physician refers a patient to physical therapy for treatment of chronic low back pain. The patient is currently receiving treatment from a massage therapist for the same problem. Which of the following actions is MOST appropriate for the physical therapist?
- Ask the patient to discontinue the massage therapy.
- Treat the patient on days the patient is not seen by the massage therapist.
- Gain permission from the patient to contact the massage therapist to discuss the plan of care.
- Discontinue the patient’s physical therapy.
- Asking the patient to discontinue massage therapy may alienate the patient and may deny the patient access to appropriate treatment therapy.
- Without knowledge of what other treatment the patient is receiving, treating the patient on days the patient is not seen by the massage therapist may be counterproductive.
- Obtaining the patient’s permission to contact the massage therapist allows communication between healthcare providers and provides the most appropriate treatment for the patient.
- Discontinuing physical therapy would not allow for the best care for the patient.
A patient has pain in the mid lower abdominal area and low back that is not of musculoskeletal origin. Which of the following diagnoses is MOST likely?
- Enlarged liver
- Inflamed pancreas
- Ruptured gallbladder
- Dissecting aortic aneurysm
- Liver pain is referred to the right shoulder, upper back, and chest and would not be consistent with the lower abdominal pain (p. 352).
- While pancreatic pain can refer to the middle or lower back, it tends to be in the epigastric and left upper quadrant region, not in the lower abdomen (p. 321, 329).
- Gallbladder pain refers to the right shoulder, chest, and upper back regions and would not be consistent with the lower abdominal pain (p. 351).
- Pain in the abdominal and lower back region can be referred by a dissecting aortic aneurysm (p. 265).
Which of the following scenarios BEST describes the effect of climatic conditions on an individual who has exercise-induced asthma?
- Bronchospasm is facilitated by exercise in a humid environment, compared with a dry environment.
- Bronchospasm is facilitated by exercise in a warm environment, compared with a cold environment.
- Bronchospasm is blunted when exercising in a humid environment, compared with a dry environment.
- Bronchospasm is blunted when exercising in a cold environment, compared with a warm environment.
- Exercise-induced asthma or bronchospasm is exacerbated in cold and dry environments, not humid environments.
- Exercise-induced asthma or bronchospasm is exacerbated in cold and dry environments, not warm environments.
- Exercise-induced asthma or bronchospasm is exacerbated in cold and dry environments and is blunted when exercising in a humid environment.
- Exercise-induced asthma or bronchospasm is exacerbated in cold environments.
Which of the following muscles should be strengthened in a patient who has an anterior trunk lean during the foot flat (loading response) phase of gait?
- Tibialis anterior
- Iliopsoas
- Quadriceps
- Triceps surae
- Ankle dorsiflexion weakness can result in inadequate dorsiflexion control during the foot flat (loading response) phase of gait (p. 308).
- Hip flexor weakness typically results in gait deviations in the swing, not stance, phase of gait (p. 308).
- Anterior trunk bending is commonly used to bring the line of force in front of the knee to compensate for weak knee extensors (p. 307).
- Triceps surae weakness can result in inadequate knee extension in stance (p. 308).
Which of the following medications for pain is MOST likely to increase risk of peptic ulcer disease?
- Codeine
- Morphine
- Ibuprofen (Motrin)
- Acetaminophen (Tylenol)
- Codeine is not a type of nonsteroidal antiinflammatory drug and will not increase risk of peptic ulcer disease (p. 600).
- Morphine is not a type of nonsteroidal antiinflammatory drug and will not increase risk of peptic ulcer disease (p. 203). A headache is the most likely problem, not light-headedness.
- Ibuprofen is a type of nonsteroidal antiinflammatory drug that impairs the gastric protective mechanism against corrosive acids (p. 225).
- Acetaminophen is not a type of nonsteroidal antiinflammatory drug and will not increase risk of peptic ulcer disease (p. 232).
After discussing with the physical therapist the benefits of therapy and the risks of refusing intervention, a patient refuses physical therapy. The patient acknowledges that without intervention, there is a high probability that this condition will worsen. Which of the following is the MOST appropriate response?
- Respect the patient’s decision to decline the therapy.
- Continue discussions with the patient on why therapy is the best option.
- Begin treatment, starting with a very easy exercise.
- Refer the patient to another therapist who may be able to establish a better rapport.
- Every adult of sound mind has a right to refuse treatment.
- If the patient has made an “informed refusal,” the right of the patient to make autonomous medical decisions should be respected.
- If the patient refuses a treatment and informed consent is not obtained, then continuing treatment can result in legal action.
- If the patient has made an “informed refusal,” the right of the patient to make autonomous medical decisions should be respected.
A patient who has an L2 radiculopathy with motor weakness would MOST likely demonstrate which of the following ipsilateral gait abnormalities?
- Pelvic drop during the swing phase of gait
- Hip lateral (external) rotation during the swing phase of gait
- Genu valgum during the stance phase of gait
- Posterior trunk bending in the stance phase of gait
- A pelvic drop during the swing phase of gait is indicative of gluteus medius weakness and is known as Trendelenburg gait (Lippert, p. 392). The gluteus medius is innervated by L4–S1 (Lippert, p. 309).
- A patient with an L2 radiculopathy would demonstrate weakness in the hip flexors. The iliopsoas is innervated by L2–L4, which would cause the patient’s hip flexion to be weak and allow muscle substitution to occur. Lateral (external) rotation may be used to facilitate hip flexion in swing phase, using the adductors as flexors, if the true hip flexors are weak. (Levine, p. 73, Lippert, p. 304; O’Sullivan)
- Dynamic genu valgum during the stance phase of gait can occur due to weakness of the ipsilateral gluteus medius (Kisner, p. 794). The gluteus medius is innervated by L4–S1 (Lippert, p. 309).
- Posterior trunk bending indicates a weakness of the hip extensors and is known as gluteus maximus gait or rocking horse gait (Lippert, pp. 391-392). The gluteus maximus is innervated by L5–S2 (Lippert, p. 307). A posterior trunk lean from initial contact to loading response is the result of either hip extensor weakness, hip flexor contracture, or inadequate hip flexion in the swing limb. Therefore, a posterior trunk bend during stance suggests either the ipsilateral gluteus maximus is weak or the contralateral hip flexors are weak. (Dutton, p. 292) The stem asks for ipsilateral.
Use of a pneumatic compression pump in the lower extremity is CONTRAINDICATED for a patient who has which of the following findings?
- Ankle-brachial index of 0.9
- Hypoproteinemia measured at less than 2 g/dL
- Resting blood pressure of 140/90 mm Hg
- Fasting blood glucose value of 118 mg/dL (6.5 mmol/L)
- Compression is generally contraindicated in patients who have severe peripheral arterial disease, as indicated by an ankle-brachial index of less than 0.6 (Cameron, p. 415).
- Hypoproteinemia less than 2 g/dL is a contraindication for compression as this intervention can increase intravascular fluid thus further lowering serum protein concentration, which can adversely affect cardiac or immunologic function (Cameron, p. 416).
- Uncontrolled hypertension is a precaution for the use of compression on a patient. Compression can be used as long as the patient’s blood pressure is monitored during use and does not exceed the physician’s recommended parameters (Cameron, p. 416). This patient’s hypertension may be controlled with medication, in which case close monitoring of blood pressure before and after treatment would help determine tolerance to the intervention (Bellew, p. 250).
- Although impaired sensation is a precaution for the use of compression on a patient (Cameron, p. 416), a fasting glucose value of 118 mg/dL (6.5 mmol/L) is considered pre-diabetes and does not necessarily mean a patient has peripheral neuropathy (ACSM).
Which of the following substitution patterns should be prevented when measuring active forearm pronation?
- Shoulder medial (internal) rotation and shoulder abduction
- Shoulder medial (internal) rotation and shoulder adduction
- Shoulder lateral (external) rotation and shoulder abduction
- Shoulder lateral (external) rotation and shoulder adduction
- Shoulder abduction and medial (internal) rotation should be avoided when measuring forearm pronation (p. 168).
- Shoulder abduction and medial (internal) rotation should be avoided when measuring forearm pronation (p. 168). Shoulder adduction should be avoided when measuring forearm supination (p. 163).
- Shoulder abduction and medial (internal) rotation should be avoided when measuring forearm pronation (p. 168). Shoulder lateral (external) rotation should be avoided when measuring forearm supination (p. 163).
- Shoulder abduction and medial (internal) rotation should be avoided when measuring forearm pronation (p. 168). Shoulder lateral (external) rotation and adduction should be avoided when measuring forearm supination (p. 163).
The presence of which of the following devices would MOST likely limit mobility activities during physical therapy?
- Ventilator
- Tracheostomy tube
- Temporary pacemaker
- Intracranial pressure monitor
- Although activity may result in sounding of ventilator alarms, patients who have mechanical ventilation can participate in activities (Johansson, p. 76). For patients who demonstrate adequate strength and medical stability to ambulate, a portable ventilator may be used (Hillegass).
- Although excessive head and neck movement should be avoided by patients who have a tracheostomy tube, mobility is feasible (Johansson, p. 75).
- Although it may be a life-threatening situation if the pacemaker becomes disconnected, patients with temporary pacemakers are able to participate in exercise and physical activity (Johansson, p. 71).
- An intracranial pressure monitor is the correct option because it takes very little to disrupt the values and interfere with the readings, such as changing the bed height. Therefore, mobility activities are significantly limited for patients who have an intracranial pressure monitor. (Johansson, p. 77)
A patient has acute bilateral trapezius spasm. Which of the following types of transcutaneous electrical nerve stimulation is MOST appropriate for pain relief for this patient?
- Burst
- Acupuncture
- Conventional
- Low-frequency
- Burst transcutaneous electrical nerve stimulation is similar to acupuncture mode in its setting, mechanism of action, and use, and is more appropriate for chronic pain conditions (Cameron).
- Acupuncture transcutaneous electrical nerve stimulation produces a painful noxious stimulus to release endorphins and may not be tolerated by a patient with acute symptoms (Cameron; O’Sullivan).
- Conventional transcutaneous electrical nerve stimulation produces sensory-level stimulation and is most likely to be tolerated by a patient in acute pain (Cameron; O’Sullivan).
- Low-frequency transcutaneous electrical nerve stimulation releases endorphins by providing a noxious stimulus and may not be tolerated by a patient with acute symptoms (Cameron; O’Sullivan).
An 82-year-old female patient has a sudden onset of muscle aching and stiffness. The patient reports fatiguing quickly and having difficulty ascending stairs. The patient denies recent illness or significant worsening of symptoms over the last week. The physical therapist notes an oral temperature of 99.9°F (38°C). Which of the following conditions is MOST consistent with this presentation?
- Multiple sclerosis
- Myasthenia gravis
- Polymyalgia rheumatica
- Guillain-Barré syndrome
- Multiple sclerosis is an inflammatory demyelinating disease that is more common in women, but the disease generally appears in women age 20-50 years. It can present with weakness and fatigue, but it generally is not accompanied by aching muscles. Although fever is possible, it would be a secondary complication. (pp. 452-453)
- Myasthenia gravis tends to affect women in the 20-30 year range. After age 50 years, the disorder is more common in men. It is characterized by muscle fatigue and weakness, but the symptoms generally affect the muscles of eye movement, chewing, swallowing, and facial expression. It is not generally associated with a fever or reports of stiffness. (pp. 454-455)
- Polymyalgia rheumatica is a systemic rheumatic inflammatory disorder that is more prevalent in persons over age 80 years and more common in women. Typical clinical presentation includes muscle aching and stiffness, low-grade fever, weakness, fatigue, and malaise, as well as possible headache, weight loss, depression, or vision changes. It is not necessarily associated with a recent illness. (pp. 442-444) Normal oral temperature is 96.8°F to 99.5°F (36°F to 37.5°C). (p. 161)
- Guillain-Barré syndrome is an acute autoimmune disorder characterized by demyelination of the peripheral nervous system. It can affect all ages, and incidence is not related to gender. The presentation is acute, with progressive weakness, and can include fever. As the patient denies any significant worsening in the previous week, this condition is less likely. The patient also did not report a recent illness prior to the development of the symptoms, which is characteristic of Guillain-Barré syndrome. (p. 454)
A patient sustained a compression injury to the axillary nerve. Which of the following actions is MOST likely to be difficult for the patient to perform?
- Elbow extension
- Shoulder flexion
- Forearm pronation
- Shoulder medial (internal) rotation
- The radial nerve innervates the elbow extensors, which would not be affected by an injury to the axillary nerve (p. 82).
- The axillary nerve innervates the deltoid muscle, which is involved with active shoulder flexion (p. 81).
- The median nerve innervates the forearm pronators, which would not be affected by an injury to the axillary nerve (p. 83).
- The muscles involved with shoulder medial (internal) rotation include the subscapularis, pectoralis major, teres major, and latissimus dorsi. These muscles are not innervated by the axillary nerve. The subscapularis nerve innervates the subscapularis, the medial and lateral pectoral nerves innervate the pectoralis major, the lower subscapular nerve innervates the teres major, and the thoracodorsal nerve innervates the latissimus dorsi. (p. 77, 592)
Which of the following interventions is MOST appropriate for treatment of a patient who has functional incontinence?
- Developing a voiding schedule
- Removal of clutter within the bathroom
- Abdominal activation exercises in supine position
- Rhythmic contractions of the pelvic floor
- A voiding schedule will not improve balance and mobility, which would help most with functional incontinence. A voiding schedule is most often recommended for bladder retraining as part of the treatment for urge incontinence. (Kauffman, p. 416)
- Removing clutter in the bathroom will improve the speed of ambulation to the toilet. Functional incontinence is defined as the loss of urine because of gait and locomotion impairments. (Kauffman, p. 416)
- Abdominal activation exercises increase abdominal pressure and may cause an increase in urinary incontinence if there is weakness in the pelvic floor musculature (Bo). This patient has functional incontinence, which is due to gait and locomotion problems (Kauffman, p. 416).
- Rhythmic contractions of the pelvic floor are indicated to strengthen the pelvic floor muscles. This does not affect the gait and locomotion impairments associated with functional incontinence. (Kauffman, pp. 416-417)
Which of the following scenarios MOST likely indicates that a patient has a unilateral lesion of the semicircular canals on the right side?
- The patient is able to maintain gaze on a target when the head is flexed to 30° and manually rotated quickly to the left side.
- The patient is able to maintain gaze on a target when the head is flexed to 30° and manually rotated quickly to the right side.
- The patient is unable to maintain gaze on a target when the head is flexed to 30° and manually rotated to quickly the left side.
- The patient is unable to maintain gaze on a target when the head is flexed to 30° and manually rotated quickly to the right side.
- A patient who has a unilateral lesion or a pathological condition of the central vestibular neurons will not be able to maintain gaze when the head is rotated quickly toward the side of the lesion.
- A patient who has a unilateral lesion or a pathology of the central vestibular neurons will not be able to maintain gaze when the head is rotated quickly toward the side of the lesion.
- A patient who has a unilateral lesion or a pathology of the central vestibular neurons will not be able to maintain gaze when the head is rotated quickly toward the side of the lesion, which is the right side for this patient.
- The head thrust test is used to examine semicircular canal (SCC) function. A patient who has a unilateral lesion or a pathology of the central vestibular neurons will not be able to maintain gaze when the head is rotated quickly toward the side of the lesion.
When using electrical stimulation to cause a contraction of innervated muscles, which of the following nerve fibers are activated FIRST?
- Small diameter nerve fibers
- Large diameter nerve fibers
- Nerve fibers that innervate the slow-twitch muscle fibers
- Nerve fibers that innervate the type I muscle fibers
- The large diameter fibers are activated first during electrically stimulated contraction, and the smaller nerve fibers are activated first during a physiologically initiated muscle contraction.
- The larger diameter nerve fibers are activated first during an electrically stimulated muscle contraction.
- Slow-twitch muscle fibers are innervated by small diameter nerve fibers, which are not activated first.
- Type I muscle fibers are the same as the slow-twitch muscle fibers, and these are innervated by small diameter nerve fibers, which are not activated first.
