Terms in this set (23) Science MedicinePhysiotherapy Save The bone cells that function in the resorption of bone tissue are called

• osteoids.
• osteocytes.
• osteoclasts.
• osteoblasts.

Correct answer: c

Rationale: Osteoclasts participate in bone

remodeling by assisting in the breakdown of bone tissue.

While performing passive range of motion for a patient, the nurse puts the ankle joint through the movements of (select all that apply)

• flexion and extension.
• inversion and eversion.
• pronation and supination
• flexion, extension, abduction, and

adduction.

• pronation, supination, rotation, and

circumduction.

Correct answers: a, b

Rationale: Common movements that occur at the

ankle include inversion, eversion, flexion, and extension.To prevent muscle atrophy, the nurse teaches the patient with a leg immobilized in traction to perform (select all that apply)

• flexion contractions.
• tetanic contractions.
• isotonic contractions.
• isometric contractions.
• 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.

A patient with tendonitis asks what the tendon does. The nurse's response is based on the knowledge that tendons

• connect bone to muscle.
• provide strength to muscle.
• lubricate joints with synovial fluid.
• 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.The increased risk for falls in the older adult is most likely due to

• changes in balance.
• decrease in bone mass.
• loss of ligament elasticity.
• 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.

While obtaining subjective assessment data related to the musculoskeletal system, it is particularly important to ask a patient about other medical problems such as

• hypertension.
• thyroid problems.
• diabetes mellitus.
• 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.When grading muscle strength, the nurse records a score of 3, which indicates

• no detection of muscular

contraction.

• a barely detectable flicker of

contraction.

• active movement against full

resistance without fatigue.

• 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).
