The nurse is preparing the client with a right neck mass for magnetic resonance imaging (MRI). Which question should the nurse ask? Select all that apply.

"Have you removed your hearing aid?" "Are you wearing any jewelry?" "Do you have a pacemaker?"

The nurse is preparing the client for magnetic resonance imaging after reports of low back pain. What statement by the client requires action by the nurse?

"I didn't remove my Transderm-Nitro patch." All metal-containing objects must be removed before the procedure, including transdermal patches containing an aluminized backing. The nurse must contact the health care provider before removing transdermal patches. Screening prior to the MRI are done for metal like joint replacements and pacemakers so clients may not be able to have an MRI. Hearing aides may also be made of metal so they may be prohibited with the diagnostic study.

The nurse is assessing a client with a musculoskeletal system condition. Which statement indicates to the nurse that the client is experiencing bone pain?

"The pain feels deep in my legs and keeps me awake at night." Explanation: Bone pain is typically described as a dull, deep ache that is "boring" in nature. This pain is not typically related to movement and may interfere with sleep. Muscular pain is described as soreness or aching and is referred to as "muscle cramps." Joint pain is felt around or in the joint and typically worsens with movement. Fracture pain is sharp and piercing and is relieved by immobilization. Sharp pain may also result from bone infection with muscle spasm or pressure on a sensory nerve.

The older client asks the nurse how best to maintain strong bones. What is the nurse's best response?

"Weight-bearing exercises can strengthen bones." Weight-bearing exercises maintain bone mass. Weight-resistance exercises maintain and strengthen muscles. Cardio training is important for heart health and weight maintenance/reduction. Range-of-motion exercises are essential for joint mobility.

The nurse is providing care to a client following a knee arthroscopy. What would the nurse expect to include in the client's plan of care?

Administering the prescribed analgesic. Explanation: After an arthroscopy, the client's entire leg is elevated without flexing the knee. A cold pack is placed over the bulky dressing covering the site where the arthroscope was inserted. A prescribed analgesic is administered as necessary. The client is allowed to resume his or her usual diet as tolerated.

A client arrives at the orthopedic physician's office stating knee pain sustained while playing soccer. A history and physical assessment is completed. The knee appears reddened with edema. Which other diagnostic testing would the nurse anticipate?

An arthroscopy An arthroscopy is the internal inspection of the joint using an arthroscope. The physician can inspect the joint for injury or deterioration and can also complete therapeutic procedures such as removing bit of torn or floating cartilage. A bone densitometry estimates bone density. A bone scan is used to detect metastatic bone lesions, fractures, or inflammatory disorders. An arthrocentesis is the aspiration of synovial fluid. An arthrocentesis may be completed during an arthroscopy.

A client is experiencing muscle weakness in the upper extremities. The client raises an arm above the head but then loses the ability to maintain the position. Muscular dystrophy is suspected. Which diagnostic test would evaluate muscle weakness or deterioration?

An electromyography Explanation: An electromyography tests the electrical potential of muscles and nerves leading to the muscles. It is done to evaluate muscle weakness or deterioration. A serum calcium test evaluates the calcium in the blood. An arthroscopy assesses changes in the joint. An MRI identifies abnormalities in the targeted area.

Which is useful in identifying acute or chronic tears of the joint capsule or supporting ligaments of the knee, shoulder, ankle, hip, or wrist?

Arthrography Explanation: Arthrography is useful in identifying acute or chronic tears of the joint capsule or supporting ligaments of the knee, shoulder, ankle, hip, or waist. Meniscography is a distractor for this question. Bone densitometry is used to estimate bone mineral density. An EMG provides information about the electrical potential of the muscles and nerves leading to them.

A patient is scheduled for a procedure that will allow the physician to visualize the knee joint in order to diagnose the patient's pain. What procedure will the nurse prepare the patient for?

Arthroscopy Arthroscopy is a procedure that allows direct visualization of a joint through the use of a fiberoptic endoscope. Thus, it is a useful adjunct to diagnosing joint disorders.

What is the term for a rhythmic contraction of a muscle?

Clonus Clonus is a rhythmic contraction of the muscle. Atrophy is a shrinkagelike decrease in the size of a muscle. Hypertrophy is an increase in the size of a muscle. Crepitus is a grating or crackling sound or sensation that may occur with movement of ends of a broken bone or irregular joint surface.

Which term refers to the shaft of the long bone?

Diaphysis Explanation: The diaphysis is primarily cortical bone. An epiphysis is an end of a long bone. Lordosis refers to an increase in lumbar curvature of spine. Scoliosis refers to lateral curving of the spine.

A client is diagnosed with a fracture of a diarthrosis joint. What is an example of this type of joint?

Elbow Explanation: A diarthrosis joint, like the elbow, is freely movable. The skull is an example of an immovable joint. The vertebral joints and symphysis pubis are amphiarthrosis joints that have limited motion.

Which diagnostic test would the nurse expect to be ordered for a client with lower extremity muscle weakness?

Electromyograph (EMG) Explanation: The EMG provides information about the electrical potential of the muscles and the nerves leading to them. The test is performed to evaluate muscle weakness, pain, and disability. An arthrocentesis, bone scan, and biopsy does not measure muscle weakness.

The nurse is performing a musculoskeletal assessment for a client whose right leg muscles exhibit no tone and are limp. Which descriptor should the nurse use to document this condition?

Flaccid Explanation: The term flaccid describes muscles that have no tone or are limp. Spastic describes muscles that have greater-than-normal tone. Atonic describes muscles that are not enervated and become soft and flabby. Atrophic describes muscles deterioration that occurs with lack of use and exercise.

The nurse is reporting on the results of client blood work to the oncoming nurse. Upon reviewing the data, it is noted that the client has an elevated uric acid level. Which inflammatory process would the nurse screen for on shift rounds?

Gout

Which of the following is the most common site of joint effusion?

Knee The most common site for joint effusion is the knee. If inflammation or fluid is suspected in a joint, consultation with a provider is indicated. The elbow, hip, and shoulder are not the most common site of joint effusion.

Which of the following deformity causes a exaggerated curvature of the lumbar spine?

Lordosis Explanation: Lordosis is an exaggerated curvature of the lumbar spine. Scoliosis is a lateral curving deviation of the spine. Kyphosis is an increased forward curvature of the thoracic spine. Steppage gait is not a type of spinal deformity.

The client presents with an exaggeration of the lumbar spine curve. How does the nurse interpret this finding?

Lordosis Explanation: Lordosis is an exaggeration of the lumbar spine curve. Kyphosis is an exaggerated convex curvature of the thoracic spine.

The nurse is preparing to assess the spine of an older adult. Which actions will the nurse take during this assessment? Select all that apply.

Measure height Ask the client to bend backward Ask the client to bend forward at the waist

An instructor is describing the process of bone development. Which of the following would the instructor describe as being responsible for the process of ossification?

Osteoblasts Explanation: Osteoblasts secrete bone matrix (mostly collagen), in which inorganic minerals, such as calcium salts, are deposited. This process of ossification and calcification transforms the blast cells into mature bone cells, called osteocytes, which are involved in maintaining bone tissue. Cortical bone is dense hard bone found in the long shafts; cancellous bone is spongy bone found in the irregular rounded edges of bone.

Which cells are involved in bone resorption?

Osteoclasts Osteoclasts carry out bone resorption by removing unwanted bone while new bone is forming in other areas. Chondrocytes are responsible for forming new cartilage. Osteoblasts are bone-forming cells that secrete collagen and other substances. Osteocytes, derived from osteoblasts, are the chief cells in bone tissue.

A 10-year-old boy who was brought to the emergency room after a skiing accident is diagnosed with a fracture of the distal end of the femur. Why is this type of fracture significant?

Potential growth problems may result from damage to the epiphyseal plate. The distal and proximal ends of a long bone are called epiphyses, which are composed of cancellous bone. The epiphyseal plate, which separates the epiphyses from the diaphysis, is the center for longitudinal growth in children. Its damage can be a critical indictor of potential growth problems if fractured. All other choices are wrong.

The nurse is caring for a client who experienced a crushing injury of the lower extremities. Which of the following symptoms is essential to be reported to the physician?

Pulselessness Explanation: Neurovascular checks (circulation, sensation, motion) are essential with a crushing injury. The absence of a pulse is a critical assessment finding to report to the physician. The other options are symptoms that need regular assessment.

A patient has a fracture of the right femur sustained in an automobile accident. What process of fracture healing does the nurse understand will occur with this patient?

Reactive phase, reparative phase, remodeling phase The process of fracture healing occurs over three phases. These include the following: Phase I: Reactive phase; Phase II: Reparative phase; and Phase III: Remodeling phase.

Which of the following is the final stage of fracture repair?

Remodeling The final stage of fracture repair consists of remodeling the new bone into its former structural arrangement. During cartilage calcification, enzymes within the matrix vesicles prepare the cartilage for calcium release and deposit. Cartilage removal occurs when the calcified cartilage is invaded by blood vessels and becomes reabsorbed by chondroblasts and osteoclasts. Angiogenesis occurs when new capillaries infiltrate the hematoma, and fibroblasts from the periosteum, endosteum, and bone marrow produce a bridge between the fractured bones.

Which statement reflects the progress of bone healing?

Serial x-rays are used to monitor the progress of bone healing. Serial x-rays are used to monitor the progress of bone healing. The type of bone fractured, the adequacy of blood supply, the surface contact of the fragments, and the general health of the client influence the rate of fracture healing. Adequate immobilization is essential until x-ray shows evidence of bone formation with ossification.

A client has a fracture that is being treated with open rigid compression plate fixation devices. What teaching will the nurse reinforce to the client about how the progress of bone healing will be monitored?

Serial x-rays will be taken. Serial x-rays are used to monitor the progress of bone healing. The plate need not be disturbed. An arthroscopy is used to visualize joints. While the bone will heal without interference, monitoring of bone healing is needed to ensure further adjustments are not necessary.

A client undergoes an invasive joint examination of the knee. What will the nurse closely monitor the client for?

Serous drainage When the client undergoes an invasive knee joint examination, the nurse should inspect the knee area for swelling, bleeding, and serous drainage. An invasive joint examination does not cause lack of sleep or appetite, depression, or shock. The client may be in shock due to the injury itself.

The nurse is assessing the client for scoliosis. What will the nurse have the client do to perform the assessment?

Stand behind the client and ask the client to bend forward at the waist. Scoliosis is characterized by a lateral curvature of the spine. The nurse stands behind the client and asks the client to bend forward at the waist for the nurse to examine the spine curvature. The nurse cannot see the spine by standing beside the client or in front of the client. The spinal curve cannot be seen by watching the client walk.

A patient is scheduled for a bone marrow biopsy. The nurse explains to the family that the bone marrow is located mainly in four areas. The nurse tells the family that the site to be used would be the:

Sternum The sternum, along with the ilium, vertebrae, and ribs are responsible for producing red blood cells and are used for bone marrow aspiration sites.

The nurse assesses soft subcutaneous nodules along the line of the tendons in a patient's hand and wrist. What does this finding indicate to the nurse?

The patient has rheumatoid arthritis. The subcutaneous nodules of rheumatoid arthritis are soft and occur within and along tendons that provide extensor function to the joints. Osteoarthritic nodules are hard and painless and represent bony overgrowth that has resulted from destruction of the cartilaginous surface of bone within the joint capsule. Lupus and neurofibromatosis are not associated with the production of nodules.

Which term refers to a grating or crackling sound or sensation?

crepitus Crepitus may occur with movement of the ends of a broken bone or irregular joint surface. Callus is fibrous tissue that forms at the fracture site. Clonus refers to rhythmic contraction of muscle. Fasciculation refers to the involuntary twitch of muscle fibers.

A client has an exaggerated convex curvature of the thoracic spine. What is this condition called?

kyphosis Explanation: Kyphosis is an exaggerated convex curvature of the thoracic spine. Lordosis is an excessive concave curvature of the lumbar spine. Scoliosis is a lateral curvature of the spine. Diaphyses are the long shafts of bones in the arms and legs.

The nurse is screening children for scoliosis. What nursing assessment finding is indicative of scoliosis?

lateral curvature of the spine Scoliosis is characterized by a lateral curvature of the spine. Loss of inches in height is seen with osteoporosis. Contracture of the wrists is a connective tissue problem. Crepitus of the knee joint is seen with joint movements.

A client scheduled to undergo an electromyography asks the nurse what this test will evaluate. What is the correct response from the nurse?

muscle weakness Electromyography tests the electric potential of the muscles and nerves leading to the muscles. It is done to evaluate muscle weakness or deterioration, pain, disability, and to differentiate muscle and nerve problems. A bone biopsy is done to identify bone composition. Bone densitometry is done to evaluate bone density. A bone scan would be appropriate to detect metastatic bone lesions.

Which serum level indicates the rate of bone turnover?

osteocalcin Serum osteocalcin (bone GLA protein) indicates the rate of bone turnover. Serum myoglobin is assessed to evaluate muscle trauma. Serum enzyme levels of creatinine kinase and aspartate aminotransferase become elevated with muscle damage.

Each bone is composed of cells, protein matrix, and mineral deposits. Which type of bone cell works to repair a bone fracture?

osteocytes During times of rapid bone growth or bone injury, osteocytes function as osteoblasts to form new bone.

The nurse is assigned to a client admitted with advanced Parkinson's disease. What type of gait correlates with Parkinson's disease?

shuffling A variety of neurologic conditions are associated with abnormal gaits, such as spastic hemiparesis gait (stroke), steppage gait (lower motor neuron disease), and shuffling gait (Parkinson's disease). Scissors gait is seen in cerebral palsy.

A nurse practitioner assesses a patient's movement in his left hand after a cast is removed. The nurse asks the patient to turn his wrist so the palm of his hand is facing up. This movement is known as:

supination

A client has undergone arthroscopy. After the procedure, the site where the arthroscope was inserted is covered with a bulky dressing. The client's entire leg is also elevated without flexing the knee. What is the appropriate nursing intervention required in caring for a client who has undergone arthroscopy?

Apply a cold pack at the insertion site. After covering the arthroscope insertion site with a bulky dressing and elevating the client's entire leg, the nurse needs to apply a cold pack at the site to minimize any chances of swelling.

A client has just undergone arthrography. What is the most important instruction for the nurse to include in the teaching plan?

Report joint crackling or clicking noises occurring after the second day. After undergoing arthrography, the client must be informed that he or she may hear crackling or clicking noises in the joints for up to 2 days, but if noises occur beyond this time, they should be reported. These noises may indicate the presence of a complication, and therefore should not be ignored or treated by the client. Massage is not indicated. The client need not be asked to avoid sunlight or dairy products.

Skull sutures are an example of which type of joint?

Synarthrosis Skull sutures are considered synarthrosis joints and are immovable. Amphiarthrosis joints allow limited movement, such as a vertebral joint. Diarthrosis joints are freely movable joints such as the hip and shoulder. Aponeuroses are broad, flat sheets of connective tissue.

The nurse working in the orthopedic surgeon's office is asked to schedule a shoulder arthrography. The nurse determines that the surgeon suspects which finding?

Tear in the joint capsule Arthrography is useful in identifying acute or chronic tears of the joint capsule or supporting ligaments of the knee, shoulder, ankle, hip, or waist. X-rays are used to diagnose bone fractures. Bone densitometry is used to estimate bone mineral density. An electromyogram (EMG) provides information about the electrical potential of the muscles and nerves leading to them.

A client is seen in the emergency room for a knee injury that happened during a basketball game. Diagnostic tests reveal torn cords of fibrous connective tissue that connect muscles to bones. What type of tear has this client sustained?

Tendon Explanation: Tendons are broad, flat sheets of connective tissue that attach muscles to bones, soft tissue, and other muscles. Ligaments bind bones together. A bursa is a synovial-filled sac, and fascia surround muscle cells.
