Chapter 61: Assessment of Musculoskeletal System
The nurse is performing a musculoskeletal assessment of an 81-year-old female patient whose mobility has been progressively decreasing in recent months. How should the nurse best assess the patient's range of motion (ROM) in the affected leg? A. Observe the patient's unassisted ROM in the affected leg. B. Perform passive ROM, asking the patient to report any pain. C. Ask the patient to lift progressive weights with the affected leg. D. Move both of the patient's legs from a supine position to full flexion.
A. Observe the patient's unassisted ROM in the affected leg. Passive ROM should be performed with extreme caution and may be best avoided when assessing older patients. Observing the patient's active ROM is more accurate and safe than asking the patient to lift weights with her legs.
Which finding from a patient's right knee arthrocentesis will be of concern to the nurse? a. Cloudy fluid b. Scant thin fluid c. Pale yellow fluid d. Straw-colored fluid
A. The presence of purulent fluid suggests a possible joint infection. Normal synovial fluid is scant in amount and pale yellow/straw-colored.
The nurse notes crackling sounds and a grating sensation with palpation of an older patient's elbow. How will this finding be documented? a. Torticollis b. Crepitation c. Subluxation d. Epicondylitis
B. Crackling sounds and a grating sensation that accompany movement are described as crepitus or crepitation. Torticollis is a twisting of the neck to one side, subluxation is a partial dislocation of the joint, and epicondylitis is an inflammation of the elbow that causes a dull ache that increases with movement.
Which medication information will the nurse identify as a concern for a patient's musculoskeletal status? a. The patient takes a daily multivitamin and calcium supplement. b. The patient takes hormone therapy (HT) to prevent "hot flashes." c. The patient has severe asthma and requires frequent therapy with oral corticosteroids. d. The patient has migraine headaches treated with nonsteroidal antiinflammatory drugs (NSAIDs).
C. Frequent or chronic corticosteroid use may lead to skeletal problems such as avascular necrosis and osteoporosis. The use of HT and calcium supplements will help prevent osteoporosis. NSAID use does not increase the risk for musculoskeletal problems.
When grading muscle strength, the nurse records a score of 3 which indicates: A. no detection of muscular contraction B. A barely detectable flicker of contraction C. active movement against full resistance without fatigue D. active movement against gravity but not against resistance
Correct answer: D Rationale: Muscle strength score of 3 indicates active movement only against gravity and not against resistance (see Table 62-4).
While performing passive range of motion for a pt, the nurse puts the ankle joint through the movements of (select all that apply): A. flexion and extension B. inversion and eversion C. pronation and supination D. flexion, extension, abduction, and abduction E. pronation, supination, rotation and circumduction
Correct answers: a, b Rationale: Common movements that occur at the ankle include inversion, eversion, flexion, and extension.
An 82-year-old patient is frustrated by her flabby belly and rigid hips. What should the nurse tell the patient about these frustrations? A. "You should go on a diet and exercise more to feel better about yourself." B. "Something must be wrong with you because you should not have these problems." C. "You have arthritis and need to go on nonsteroidal antiinflammatory drugs (NSAIDs)." D. "Decreased muscle mass and strength and increased hip rigidity are normal changes of aging."
D. "Decreased muscle mass and strength and increased hip rigidity are normal changes of aging." The musculoskeletal system's normal changes of aging include decreased muscle mass and strength; increased rigidity in the hips, neck, shoulders, back, and knees; decreased fine motor dexterity; and slowed reaction times. Going on a diet and exercising will help but not stop these changes. Telling the patient "Something must be wrong with you..." will not be helpful to the patient's frustrations.
Which finding is of highest priority when the nurse is planning care for a 77-year-old patient seen in the outpatient clinic? a. Symmetric joint swelling of fingers b. Decreased right knee range of motion c. Report of left hip aching when jogging d. History of recent loss of balance and fall
D. A history of falls requires further assessment and development of fall prevention strategies. The other changes are more typical of bone and joint changes associated with normal aging.
The nurse who notes that a 59-year-old female patient has lost 1 inch in height over the past 2 years will plan to teach the patient about a. discography studies. b. myelographic testing. c. magnetic resonance imaging (MRI). d. dual-energy x-ray absorptiometry (DXA).
D. The decreased height and the patient's age suggest that the patient may have osteoporosis and that bone density testing is needed. Discography, MRI, and myelography are typically done for patients with current symptoms caused by musculoskeletal dysfunction and are not the initial diagnostic tests for osteoporosis.
The bone cells that function in the resorption of bone tissue are called a.osteoids b.osteocytes c.osteoclasts d.osteoblasts
c.osteoclasts Osteoclasts participate in bone remodeling by assisting in the breakdown of bone tissue.
crepitation
crackling sound or grating sensation as a result of friction between bones
osteon
cylindrical structural units that fit closely together in compact bone, creating a dense bone structure
isotonic contractions
muscular contraction with shortening that produces movement
Bursae:
small sacs of connective tissue lined with synovial membrane that contain synovial fluid.
When working with patients, the nurse knows that patients have the most difficulties with diarthrodial joints. Which joints are included in this group of joints (select all that apply)? A. Hinge joint of the knee B. Ligaments joining the vertebrae C. Fibrous connective tissue of the skull D. Ball and socket joint of the shoulder or hip E. Cartilaginous connective tissue of the pubis joint
A . Hinge joint of the knee D. Ball and socket joint of the shoulder or hip The diarthrodial joints include the hinge joint of the knee and elbow, the ball and socket joint of the shoulder and hip, the pivot joint of the radioulnar joint, and the condyloid, saddle, and gliding joints of the wrist and hand. The ligaments and cartilaginous connective tissue joining the vertebrae and pubis joint and the fibrous connective tissue of the skull are synarthrotic joints.
The nurse admits a 55-year-old female with multiple sclerosis to a long-term care facility. Which finding is of most immediate concern to the nurse? A. Ataxic gait B. Radicular pain C. Severe fatigue D. Urinary retention
A. Ataxic gait An ataxic gait is a staggering, uncoordinated gait. Fall risk is the highest in individuals with gait instability or visual or cognitive impairments. The other signs and symptoms (e.g., fatigue, urinary retention, radicular pain) may also occur in the patient with multiple sclerosis and need to be managed, but are not the priority.
The nurse admits a 55-year-old female with multiple sclerosis to a long-term care facility. Which finding is of most immediate concern to the nurse? A. Ataxic gait B. Radicular pain C. Severe fatigue D. Urinary retention
A. Ataxis gait An ataxic gait is a staggering, uncoordinated gait. Fall risk is the highest in individuals with gait instability or visual or cognitive impairments. The other signs and symptoms (e.g., fatigue, urinary retention, radicular pain) may also occur in the patient with multiple sclerosis and need to be managed, but are not the priority.
A 50-year-old patient is reporting a sore shoulder after raking the yard. The nurse should suspect which problem? A. Bursitis B. Fasciitis C. Sprained ligament D. Achilles tendonitis
A. Bursitis Bursitis is common in adults over age 40 and with repetitive motion, such as raking. Plantar fasciitis frequently occurs as a stabbing pain at the heel caused by straining the ligament that supports the arch. Achilles tendonitis is an inflammation of the tendon that attaches the calf muscle to the heel bone, not the shoulder, and causes pain with walking or running. A sprained ligament occurs when a ligament is stretched or torn from a direct injury or sudden twisting of the joint, not repetitive motion.

A 72-year-old patient with kyphosis is scheduled for dual-energy x-ray absorptiometry (DXA) testing. The nurse will plan to a. explain the procedure. b. start an IV line for contrast medium injection. c. give an oral sedative 60 to 90 minutes before the procedure. d. screen the patient for allergies to shellfish or iodine products.
A. DXA testing is painless and noninvasive. No IV access is necessary. Contrast medium is not used. Because the procedure is painless, no antianxiety medications are required.
When working with patients, the nurse knows that patients have the most difficulties with diarthrodial joints. Which joints are included in this group of joints? (Select all that apply.) A. Hinge joint of the knee B. Ligaments joining the vertebrae C. Fibrous connective tissue of the skull D. Ball and socket joint of the shoulder or hip E. Cartilaginous connective tissue of the pubis joint
A. Hinge joint of the knee D. Ball and socket joint of the shoulder or hip The diarthrodial joints include the hinge joint of the knee and elbow, the ball and socket joint of the shoulder and hip, the pivot joint of the radioulnar joint, and the condyloid, saddle, and gliding joints of the wrist and hand.

A. Observe the patient's unassisted ROM in the affected leg. Passive ROM should be performed with extreme caution and may be best avoided when assessing older patients. Observing the patient's active ROM is more accurate and safe than asking the patient to lift weights with her legs.
A patient has a new order for magnetic resonance imaging (MRI) to evaluate for left femur osteomyelitis after a hip replacement surgery. Which information indicates that the nurse should consult with the health care provider before scheduling the MRI? a. The patient has a pacemaker. b. The patient is claustrophobic. c. The patient wears a hearing aid. d. The patient is allergic to shellfish.
A. Patients with permanent pacemakers cannot have MRI because of the force exerted by the magnetic field on metal objects. An open MRI will not cause claustrophobia. The patient will need to be instructed to remove the hearing aid before the MRI, but this does not require consultation with the health care provider. Because contrast medium will not be used, shellfish allergy is not a contraindication to MRI.
Which nursing action is correct when performing the straight-leg raising test for an ambulatory patient with back pain? a. Raise the patient's legs to a 60-degree angle from the bed. b. Place the patient initially in the prone position on the exam table. c. Have the patient dangle both legs over the edge of the exam table. d. Instruct the patient to elevate the legs and tense the abdominal muscles.
A. When performing the straight leg-raising test, the patient is in the supine position and the nurse passively lifts the patient's legs to a 60-degree angle. The other actions would not be correct for this test.
A 42-year-old man who is scheduled for an arthrocentesis arrives at the outpatient surgery unit and states, "I do not want this procedure done today." Which response by the nurse is most appropriate? A. "When would you like to reschedule the procedure?" B. "Tell me what your concerns are about this procedure." C. "The procedure is safe, so why should you be worried?" D. "The procedure is not painful because an anesthetic is used."
B. "Tell me what your concerns are about this procedure." The nurse should use therapeutic communication to determine the patient's concern about the procedure. The nurse should not provide false reassurance. It is not appropriate for the nurse to assume the patient is concerned about pain or to assume the patient is asking to reschedule the procedure.

A 57-year-old postmenopausal woman is scheduled for dual-energy x-ray absorptiometry (DXA). Which statement, if made by the patient to the nurse, indicates understanding of the procedure? A. "The bone density in my heel will be measured." B. "This procedure will not cause any pain or discomfort." C. "I will not be exposed to any radiation during the procedure." D. "I will need to remove my hearing aids before the procedure."
B. "This procedure will not cause any pain or discomfort." Dual-energy x-ray absorptiometry (DXA) is painless and measures the bone mass of spine, femur, forearm, and total body with minimal radiation exposure. A quantitative ultrasound (QUS) evaluates density, elasticity, and strength of bone using ultrasound of the calcaneus (heel). Magnetic resonance imaging would require removal of objects such as hearing aids that have metal parts.

Which information in a 67-year-old woman's health history will alert the nurse to the need for a more focused assessment of the musculoskeletal system? a. The patient sprained her ankle at age 13. b. The patient's mother became shorter with aging. c. The patient takes ibuprofen (Advil) for occasional headaches. d. The patient's father died of complications of miliary tuberculosis.
B. A family history of height loss with aging may indicate osteoporosis, and the nurse should perform a more thorough assessment of the patient's current height and other risk factors for osteoporosis. A sprained ankle during adolescence does not place the patient at increased current risk for musculoskeletal problems. A family history of tuberculosis is not a risk factor. Occasional nonsteroidal antiinflammatory drug (NSAID) use does not indicate any increased musculoskeletal risk.
A female patient with a long-standing history of rheumatoid arthritis has sought care because of increasing stiffness in her right knee that has culminated in complete fixation of the joint. The nurse would document the presence of which problem? A. Atrophy B. Ankylosis C. Crepitation D. Contracture
B. Ankylosis Ankylosis is stiffness or fixation of a joint, whereas contracture is reduced movement as a consequence of fibrosis of soft tissue (muscles, ligaments, or tendons). Atrophy is a flabby appearance of muscle leading to decreased function and tone. Crepitation is a grating or crackling sound that accompanies movement.

A patient with left knee pain is diagnosed with bursitis. The nurse will explain that bursitis is an inflammation of a. the synovial membrane that lines the joint. b. a small, fluid-filled sac found at some joints. c. the fibrocartilage that acts as a shock absorber in the knee joint. d. any connective tissue that is found supporting the joints of the body.
B. Bursae are fluid-filled sacs that cushion joints and bony prominences. Fibrocartilage is a solid tissue that cushions some joints. Bursae are a specific type of connective tissue. The synovial membrane lines many joints but is not a bursa.
Which action can the nurse delegate to unlicensed assistive personnel (UAP) who are working in the orthopedic clinic? a. Grade leg muscle strength for a patient with back pain. b. Obtain blood sample for uric acid from a patient with gout. c. Perform straight-leg-raise testing for a patient with sciatica. d. Check for knee joint crepitation before arthroscopic surgery.
B. Drawing blood specimens is a common skill performed by UAP in clinic settings. The other actions are assessments and require registered nurse (RN)-level judgment and critical thinking.
The home care nurse visits an 84-year-old woman with pneumonia after her discharge from the hospital. Which assessment finding would the nurse expect because of age-related changes in the musculoskeletal system? A. Positive straight-leg-raising test B. Muscle strength is scale grade 3/5 C. Lateral S-shaped curvature of the spine D. Fingers drift to the ulnar side of the forearm
B. Muscle strength is scale grade 3/5 Decreased muscle strength is an age-related change of the musculoskeletal system caused by decreased number and size of the muscle cells. The other assessment findings indicate musculoskeletal abnormalities. A positive straight-leg-raising test indicates nerve root irritation from intervertebral disk prolapse and herniation. An ulnar deviation or drift indicates rheumatoid arthritis due to tendon contracture. Scoliosis is a lateral curvature of the spine.
In reviewing bone remodeling, what should the nurse know about the involvement of bone cells? A. Osteoclasts add canaliculi. B. Osteoblasts deposit new bone. C. Osteocytes are mature bone cells. D. Osteons create a dense bone structure.
B. Osteoblasts deposit new bone. Bone remodeling is achieved when osteoclasts remove old bone and osteoblasts deposit new bone. Osteocytes are mature bone cells, and osteons or Haversian systems create a dense bone structure, but these are not involved with bone remodeling.

A 42-year-old male patient complains of shoulder pain when the nurse moves his arm behind the back. Which question should the nurse ask? a. "Are you able to feed yourself without difficulty?" b. "Do you have difficulty when you are putting on a shirt?" c. "Are you able to sleep through the night without waking?" d. "Do you ever have trouble lowering yourself to the toilet?"
B. The patient's pain will make it more difficult to accomplish tasks like putting on a shirt or jacket. This pain should not affect the patient's ability to feed himself or use the toilet because these tasks do not involve moving the arm behind the patient. The arm will not usually be positioned behind the patient during sleeping.

A 63-year-old woman has been taking prednisone (Deltasone) daily for several years after a kidney transplant to prevent organ rejection. What is most important for the nurse to assess? A. Staggering gait B. Ruptured tendon C. Back or neck pain D. Tardive dyskinesia
C. Back or neck pain Osteoporosis with resultant fractures is a frequent and serious complication of systemic corticosteroid therapy. The ribs and vertebrae are affected the most, and patients should be observed for signs of compression fractures (back and neck pain). Phenytoin (Dilantin) is an antiseizure medication. An adverse effect of phenytoin is an ataxic (or staggering) gait. A rare adverse effect of ciprofloxacin (Cipro) and other fluoroquinolones is tendon rupture, usually of the Achilles tendon. The highest risk is in people age 60 and older and in people taking corticosteroids. Antipsychotics and antidepressants may cause tardive dyskinesia, which is characterized by involuntary movements of the tongue and face.

Which information obtained during the nurse's assessment of a 30-year-old patient's nutritional-metabolic pattern may indicate the risk for musculoskeletal problems? a. The patient takes a multivitamin daily. b. The patient dislikes fruits and vegetables. c. The patient is 5 ft 2 in and weighs 180 lb. d. The patient prefers whole milk to nonfat milk.
C. The patient's height and weight indicate obesity, which places stress on weight-bearing joints. The use of whole milk, avoiding fruits and vegetables, and use of a daily multivitamin are not risk factors for musculoskeletal problems.
After completing the health history, the nurse assessing the musculoskeletal system will begin by a. having the patient move the extremities against resistance. b. feeling for the presence of crepitus during joint movement. c. observing the patient's body build and muscle configuration. d. checking active and passive range of motion for the extremities.
C. The usual technique in the physical assessment is to begin with inspection. Abnormalities in muscle mass or configuration will allow the nurse to perform a more focused assessment of abnormal areas. The other assessments are also included in the assessment but are usually done after inspection.
The increased risk for falls in the older adult is most likely due to: A. changes in balance B. Decrease in bone mass C. Loss of ligament elasticity D. Erosion of articular cartilage
Correct answer: a Rationale: Aging can cause changes in a person's sense of balance, making the person unsteady, and proprioception may be altered. The risk for falls also increases in older adults partly because of a loss of strength.
A normal assessment finding of the musculoskeletal system is A. No deformity or crepitation B. muscle and bone strength of 4 C. ulnar deviation and sublaxation D. angulation of bone toward midline
Correct answer: a Rationale: Normal physical assessment findings of the musculoskeletal system include normal spinal curvatures; no muscle atrophy or asymmetry; no joint swelling, deformity, or crepitation; no tenderness on palpation of muscles and joints; full range of motion of all joints without pain or laxity; and muscle strength score of 5.
A pt with tendonitis asks what the tendon does. The nurses's response in based on the knowledge that the tendons A. connect bone to muscle B. provide strength to the muscle C. lubricate joints with synovial fluid D. relieve friction between moving parts
Correct answer: a Rationale: Tendons are composed of dense, fibrous connective tissue that contains bundles of closely packed collagen fibers arranged in the same plane for additional strength. They connect the muscle sheath to adjacent bone
A pt is scheduled for an electromyogram (EMG). The nurse explains that this diagnostic test involves: A. incision or puncture of the joint capsule B. insertion of small needles into certain muscles C. administration of a radioisotope before the procedure D. placement of skin electrodes to record muscle activity
Correct answer: b Rationale: Electromyography (EMG) is an evaluation of electrical potential associated with skeletal muscle contraction. Small-gauge needles are inserted into certain muscles and attached to leads that record electrical activity of muscle. Results provide information related to lower motor neuron dysfunction and primary muscle disease.
The bone cells that function in the resorption of bone tissue are called: A. osteoids B. osteocytes C. osteocytes D. osteoblasts
Correct answer: c Rationale: Osteoclasts participate in bone remodeling by assisting in the breakdown of bone tissue.
While obtaining subjective assessment data r/t to the musculoskeletal system, it is particularly important to ask a pt about other medical problems such as: A. hypertension B. thyroid problems C. diabetes mellitus D. chronic bronchitis
Correct answer: c Rationale: The nurse should question the patient about past medical problems because certain illnesses are known to affect the musculoskeletal system directly or indirectly. These diseases include tuberculosis, poliomyelitis, diabetes mellitus, parathyroid problems, hemophilia, rickets, soft tissue infection, and neuromuscular disabilities.
To prevent muscle atrophy, the nurse teaches the pt with a leg immobilized in traction to perform (select all that apply): A. flexion contraction B. tetanic contractions C. isotonic contractions D. isometric contractions E. extension contractions
Correct answer: d Rationale: Isometric contractions increase the tension within a muscle but do not produce movement. Repeated isometric contractions make muscles grow larger and stronger. Muscular atrophy (i.e., decrease in size) occurs with the absence of contraction that results from immobility.
An 82-year-old patient is frustrated by her flabby belly and rigid hips. What should the nurse tell the patient about these frustrations? A. "You should go on a diet and exercise more to feel better about yourself." B. "Something must be wrong with you because you should not have these problems." C. "You have arthritis and need to go on nonsteroidal antiinflammatory drugs (NSAIDs)." D. "Decreased muscle mass and strength and increased hip rigidity are normal changes of aging."
D. "Decreased muscle mass and strength and increased hip rigidity are normal changes of aging." The musculoskeletal system's normal changes of aging include decreased muscle mass and strength; increased rigidity in the hips, neck, shoulders, back, and knees; decreased fine motor dexterity; and slowed reaction times. Going on a diet and exercising will help but not stop these changes. Telling the patient "Something must be wrong with you..." will not be helpful to the patient's frustrations.
The nurse finds that a patient can flex the arms when no resistance is applied but is unable to flex when the nurse applies light resistance. The nurse should document the patient's muscle strength as level a. 0. b. 1. c. 2. d. 3.
D. A level 3 indicates that the patient is unable to move against resistance but can move against gravity. Level 1 indicates minimal muscle contraction, level 2 indicates that the arm can move when gravity is eliminated, and level 4 indicates active movement with some resistance.
A 54-year-old patient is about to have a bone scan. In teaching the patient about this procedure, the nurse should include what information? A. Two additional follow-up scans will be required. B. There will be only mild pain associated with the procedure. C. The procedure takes approximately 15 to 30 minutes to complete. D. The patient will be asked to drink increased fluids after the procedure.
D. The patient will be asked to drink increased fluids after the procedure. Patients are asked to drink increased fluids after a bone scan to aid in excretion of the radioisotope, if not contraindicated by another condition. No follow-up scans and no pain are associated with bone scans that take 1 hour of lying supine.

The types of bone cells include osteoblasts, osteocytes and osteoclasts. What are their funcionts?
Osteoblasts synthesize organic bone matrix (collagen) and are the basic bone-forming cells. Osteocytes are the mature bone cells. Osteoclasts participate in bone remodeling by assisting in the breakdown of bone tissue.
Ankylosis:
Stiffness or fixation of a joint, usually caused by destruction of articular cartilage and subchondral bone
Type of cartilage and where they are found:
Types of cartilage tissue include: hyaline: The most common, is found in the trachea, bronchi, nose, epiphyseal plate and articular surfaces of bones. elastic: Is found in ear, epiglottis and larynx fibrous: Tough tissue found between vertebral discs and the bones of the pelvic girdle, knee and shoulder
scoliosis
a lateral S-shaped curvature of the thoracic and lumbar spine
The increased risk for falls in the older adult is most likely due to a.changes in balance. b.decrease in bone mass. c.loss of ligament elasticity. d.erosion of articular cartilage.
a.changes in balance Aging can cause changes in a person's sense of balance, making the person unsteady, and proprioception may be altered. The risk for falls also increases in older adults partly because of a loss of strength.
A patient with tendonitis asks what the tendon does. The nurse's response is based on the knowledge that tendons a.connect bone to muscle. b.provide strength to muscle. c.lubricate joints with synovial fluid. d.relieve friction between moving parts.
a.connect bone to muscle Tendons are composed of dense, fibrous connective tissue that contains bundles of closely packed collagen fibers arranged in the same plane for additional strength. They connect the muscle sheath to adjacent bone.
While performing passive range of motion for a patient, the nurse puts the ankle joint through the movements of (select all that apply) a.flexion and extension. b.inversion and eversion. c.pronation and supination d.flexion, extension, abduction, and adduction. e.pronation, supination, rotation, and circumduction.
a.flexion and extension. b.inversion and eversion. Common movements that occur at the ankle include inversion, eversion, flexion, and extension.
A normal assessment finding of the musculoskeletal system is a.no deformity or crepitation. b.muscle and bone strength of 4. c.ulnar deviation and subluxation. d.angulation of bone toward midline.
a.no deformity or crepitation Normal physical assessment findings of the musculoskeletal system include normal spinal curvatures; no muscle atrophy or asymmetry; no joint swelling, deformity, or crepitation; no tenderness on palpation of muscles and joints; full range of motion of all joints without pain or laxity; and muscle strength score of 5.
contracture
an abnormal, usually permanent condition of a joint, characterized by flexion and fixation; may be caused by atrophy and shortening of muscle fibers resulting from immobilization or by loss of the normal elasticity of connective tissues or the skin, such as from the formation of extensive scar tissue over a joint
kyphosis
anteroposterior or forward bending of spine with convexity of curve in posterior direction; common at thoracic and sacral levels
A patient is scheduled for an electromyogram (EMG). The nurse explains that this diagnostic test involves a.incision or puncture of the joint capsule. b.insertion of small needles into certain muscles. c.administration of a radioisotope before the procedure. d.placement of skin electrodes to record muscle activity.
b.insertion of small needles into certain muscles Electromyography (EMG) is an evaluation of electrical potential associated with skeletal muscle contraction. Small-gauge needles are inserted into certain muscles and attached to leads that record electrical activity of muscle. Results provide information related to lower motor neuron dysfunction and primary muscle disease
While obtaining subjective assessment data related to the musculoskeletal system, it is particularly important to ask a patient about other medical problems such as a.hypertension. b.thyroid problems. c.diabetes mellitus. d.chronic bronchitis.
c.diabetes mellitus The nurse should question the patient about past medical problems because certain illnesses are known to affect the musculoskeletal system directly or indirectly. These diseases include tuberculosis, poliomyelitis, diabetes mellitus, parathyroid problems, hemophilia, rickets, soft tissue infection, and neuromuscular disabilities.
When grading muscle strength, the nurse records a score of 3, which indicates a.no detection of muscular contraction. b.a barely detectable flicker of contraction. c.active movement against full resistance without fatigue. d.active movement against gravity but not against resistance.
d. active movement against gravity but not against resistance Muscle strength score of 3 indicates active movement only against gravity and not against resistance
To prevent muscle atrophy, the nurse teaches the patient with a leg immobilized in traction to perform (select all that apply) a.flexion contractions. b.tetanic contractions. c.isotonic contractions. d.isometric contractions. e.extension contractions.
d.isometric contractions Isometric contractions increase the tension within a muscle but do not produce movement. Repeated isometric contractions make muscles grow larger and stronger. Muscular atrophy (i.e., decrease in size) occurs with the absence of contraction that results from immobility.
arthrocentesis
incision or puncture of joint capsule to obtain samples of synovial fluid from within joint cavity or to remove excess fluid; used for diagnostic purposes, to instill medications, and to remove fluid from the joints to relieve pain
arthroscopy
insertion of an arthroscope into a joint for visualization or surgery
lordosis
lumbar spinal deformity resulting in anteroposterior curvature with concavity in posterior direction
isometric contractions
muscular contraction that increases tension but does not produce movement
What are some effects of aging on the musculoskeletal system?
o Increased bone resorption and decreased bone formation cause a loss of bone density, contributing to development of osteopenia and osteoporosis. o Tendons and ligaments become less flexible; movement becomes stiff. • Osteoarthritis and osteoporosis are NOT NORMAL consequences of aging.
the main functions of bone are:
support, protection of internal organs, voluntary movement, blood cell production, and mineral storage.
atrophy
wasting of muscle, characterized by decreased circumference and flabby appearance leading to decreased function and tone
