Musculoskeletal System Questions Flashcards
A patient is being assessed for range-of-joint movement. The nurse asks him to move his arm in toward the center of his body. What is this movement called?
a. Flexion
b. Abduction
c. Adduction
d. Extension
ANS: C
Moving a limb toward the midline of the body is called adduction; moving a limb away from the midline of the body is called abduction. Flexion is bending a limb at a joint; and extension is straightening a limb at a joint.
A patient tells the nurse that she is having a hard time bringing her hand to her mouth when she eats or tries to brush her teeth. The nurse knows that for her to move her hand to her mouth, she must perform which movement?
a. Flexion
b. Abduction
c. Adduction
d. Extension
ANS: A
Flexion, or bending a limb at a joint, is required to move the hand to the mouth. Extension is straightening a limb at a joint. Moving a limb toward the midline of the body is called adduction; abduction is moving a limb away from the midline of the body.
What are the functional units of the musculoskeletal system?
a. Bones
b. Joints
c. Muscles
d. Tendons
ANS: B
Joints are the functional units of the musculoskeletal system because they permit the mobility needed to perform the activities of daily living. The skeleton (bones) is the framework of the body. There are three types of muscles: skeletal, smooth, and cardiac and
they produce movement when they contract. Tendons are strong fibrous cords that attach skeletal muscles to the bones. The other
options are not correct.
When reviewing the musculoskeletal system, the nurse should recall that hematopoiesis takes place where?
a. Liver
b. Spleen
c. Kidneys
d. Bone marrow
ANS: D
The musculoskeletal system functions to encase and protect the inner vital organs, to support the body, to produce red blood cells (hematopoiesis) in the bone marrow, and to store minerals. The other options are not correct. The liver has many functions such as detoxifying the blood, production of bile, and synthesis of proteins needed for blood to clot, but hematopoiesis is not one of its functions. The spleen has many functions such as filtering the blood as part of the immune system, recycling old red blood cells, and storing platelets and white bloods cells but it is not the location of hematopoiesis. The kidney also has many functions such as maintaining fluid balance, filtering minerals, and production of hormones that help stimulate red blood cells production; however,
it is not the location of hematopoiesis.
What are the fibrous bands that run directly from one bone to another, strengthen the joint, and help prevent movement in undesirable directions called?
a. Bursa
b. Tendons
c. Cartilage
d. Ligaments
ANS: D
Fibrous bands running directly from one bone to another that strengthen the joint and help prevent movement in undesirable directions are called ligaments. The other options are not correct.
The nurse notices that a woman in an exercise class is unable to do one-person jump rope. What does the nurse know that the shoulder must be able to do in order for one to be able to do one-person jump rope?
a. Inversion
b. Supination
c. Protraction
d. Circumduction
ANS: D
Circumduction is defined as moving the arm in a circle around the shoulder. This movement is necessary to perform one-person jump rope. Inversion is the moving of the sole of the foot inward at the ankle. Supination is turning the forearm so the palm is down. Protraction is moving a body part forward and parallel to the ground.
What is the articulation of the mandible and the temporal bone called?
a. Intervertebral foramen
b. Condyle of the mandible
c. Temporomandibular joint
d. Zygomatic arch of the temporal bone
ANS: C
The articulation of the mandible and the temporal bone is the temporomandibular joint. The other responses are not correct.
To palpate the temporomandibular joint, where should the nurse place his or her fingers?
a. The depression inferior to the tragus of the ear
b. The depression superior to the tragus of the ear
c. The depression anterior to the tragus of the ear
d. The depression posterior to the tragus of the ear
ANS: C
The temporomandibular joint can be felt in the depression anterior to the tragus of the ear. The other locations are not correct.
Of the 33 vertebrae in the spinal column, which is correct?
a. 5 lumbar
b. 5 thoracic
c. 7 sacral
d. 12 cervical
ANS: A
There are 7 cervical, 12 thoracic, 5 lumbar, 5 sacral, and 3 to 4 coccygeal vertebrae in the spinal column.
If an imaginary line were drawn connecting the highest point on each iliac crest. What vertebra would that line cross?
a. First sacral
b. Fourth lumbar
c. Seventh cervical
d. Twelfth thoracic
ANS: B
An imaginary line connecting the highest point on each iliac crest crosses the fourth lumbar vertebra. The other options are not
correct.
The nurse is explaining to a patient that there are shock absorbers in his back to cushion the spine and to help it move. What is the nurse referring to as shock absorbers?
a. Vertebral column
b. Nucleus pulposus
c. Vertebral foramen
d. Intervertebral disks
ANS: D
Intervertebral disks are elastic fibrocartilaginous plates that cushion the spine similar to shock absorbers and help it move. The vertebral column is the spinal column itself. The nucleus pulposus is located in the center of each disk. The vertebral foramen is the
channel, or opening, for the spinal cord in the vertebrae.
The nurse is providing patient education for a man who has been diagnosed with a rotator cuff injury. When explaining the structures involved in his injury, what should the nurse include?
a. Nucleus pulposus
b. Medial epicondyle
c. Glenohumeral joint
d. Articular processes
ANS: C
A rotator cuff injury involves the glenohumeral joint, which is enclosed by a group of four powerful muscles and tendons that support and stabilize it. The other options are not in or near the rotator cuff or shoulder. The nucleus pulposus is located in the center of each intervertebral disk. The articular processes are projections in each vertebral disk that lock onto the next vertebra, thereby stabilizing the spinal column. The medial epicondyle is located at the elbow.
During an interview, the patient states, “I can feel this bump on the top of both of my shoulders—it doesn’t hurt but I am curious about what it might be.” What should the nurse tell this patient?
a. “That is the subacromial bursa.”
b. “That is the acromion process.”
c. “That is the glenohumeral joint.”
d. “That is the greater tubercle of the humerus.”
ANS: B
The bump of the scapula’s acromion process is felt at the very top of the shoulder. The other options are not correct.
The nurse is checking the range of motion in a patient’s knee and knows that the knee is capable of which movement(s)?
a. Circumduction
b. Flexion and extension
c. Inversion and eversion
d. Supination and pronation
ANS: B
The knee is a hinge joint, permitting flexion and extension of the lower leg on a single plane. The knee is not capable of circumduction, inversion, eversion, supination, or pronation.
A patient is visiting the clinic for an evaluation of a swollen, painful knuckle. The nurse notices that the knuckle above his ring on the left hand is swollen and that he is unable to remove his wedding ring. What is the name of this patient’s affected joint?
a. Tibiotalar
b. Interphalangeal
c. Tarsometatarsal
d. Metacarpophalangeal
ANS: D
The joint located just above the ring on the finger is the metacarpophalangeal joint. The interphalangeal joint is located distal to the metacarpophalangeal joint. The tarsometatarsal and tibiotalar joints are found in the foot and ankle.
The nurse is assessing a patient’s ischial tuberosity. How should the nurse position the patient to palpate the ischial tuberosity?
a. Standing
b. Flexing the hip
c. Flexing the knee
d. Lying in the supine position
ANS: B
The ischial tuberosity lies under the gluteus maximus muscle and is palpable when the hip is flexed. The other options are not correct.
The nurse is examining the hip area of a patient and palpates a flat depression on the upper, lateral side of the thigh when the patient is standing. What is the nurse palpating?
a. Iliac crest
b. Ischial tuberosity
c. Greater trochanter
d. Gluteus maximus muscle
ANS: C
The greater trochanter of the femur is palpated when the person is standing, and it appears as a flat depression on the upper lateral side of the thigh. The iliac crest is the upper part of the hip bone; the ischial tuberosity lies under the gluteus maximus muscle and
is palpable when the hip is flexed; and the gluteus muscle is part of the buttocks. The iliac crest is the upper part of the hip bone (not lateral); the ischial tuberosity lies under the gluteus maximus muscle and is palpable when the hip is flexed (not standing); and
the gluteus muscle is part of the buttocks. The flat depression in the upper lateral side of the thigh that the nurse is palpating is the greater trochanter.
What is articulated with the tibia and fibula in the ankle joint?
a. Talus
b. Cuboid
c. Calcaneus
d. Cuneiform bones
ANS: A
The ankle or tibiotalar joint is the articulation of the tibia, fibula, and talus. The other bones listed are foot bones and not part of the ankle joint.
A woman who is 8 months pregnant comments that she has noticed a change in her posture and is having lower back pain. The nurse tells her that during pregnancy, women have a posture shift to compensate for the enlarging fetus. What is the term for this shift in posture?
a. Lordosis
b. Scoliosis
c. Ankylosis
d. Kyphosis
ANS: A
Lordosis compensates for the enlarging fetus, which would shift the center of balance forward. This shift in balance, in turn, creates a strain on the low back muscles, felt as low back pain during late pregnancy by some women. Scoliosis is lateral curvature of portions of the spine; ankylosis is extreme flexion of the wrist, as observed with severe rheumatoid arthritis; and kyphosis is an enhanced thoracic curvature of the spine. Scoliosis is lateral curvature of portions of the spine; ankylosis is extreme flexion of the wrist, as observed with severe rheumatoid arthritis; and kyphosis is an enhanced thoracic curvature of the spine. The symptoms this patient is experiencing are lordosis.
An 85-year-old patient comments during his annual physical examination that he seems to be getting shorter as he ages. Why does height decrease with aging?
a. The vertebral column shortens.
b. Long bones tend to shorten with age.
c. A significant loss of subcutaneous fat occurs.
d. A thickening of the intervertebral disks develops.
ANS: A
Postural changes are evident with aging and decreased height is most noticeable due to shortening of the vertebral column. Long bones do not shorten with age. Intervertebral disks actually get thinner with age. Subcutaneous fat is not lost but is redistributed to
the abdomen and hips.
