, 1. A nurse observes a patient rising from a chair slowly by pushing on the
j j j j j j j j j j j j j j




chair arms.Which type of tension and contraction did the nurseobserve?
j j j j j j j j j j




a. Eccentrictension andisotonic contraction j j j j




b. Eccentrictensionand isometric contraction j j j j




c. Concentrictension andisotonic contraction j j j j




d. Concentric tension andisometric contraction j j j j




ANS:A j




This movement causes eccentric tension and isotonic contraction. Eccentric tension helps control the
j j j j j j j j j j j j j




speed and direction of movement. For example, when using an overhead trapeze, the patient slowly
j j j j j j j j j j j j j j j




lowers himself to the bed. The lowering is controlled when the antagonistic muscles lengthen. By
j j j j j j j j j j j j j j j




pushing on the chair arms and rising eccentric tension and isotonic contraction occurred. In concentric
j j j j j j j j j j j j j j j




tension, increased muscle contraction causes muscle shortening, resulting in movement such as when a
j j j j j j j j j j j j j j




patient uses an overhead trapeze to pull up in bed. Concentric and eccentric muscle actions are
j j j j j j j j j j j j j j j j




necessary for active movement and therefore are referred to as dynamic or isotonic contraction.
j j j j j j j j j j j j j j




Isometric contraction (static contraction) causes an increase in muscle tension or muscle work but no
j j j j j j j j j j j j j j j




shortening or active movement of the muscle (e.g., instructing the patient to tighten and relax a muscle
j j j j j j j j j j j j j j j j j




group, as in quadriceps set exercises or pelvic floor exercises).

2. A nurse notices that a patient has a structural curvature of the spine
j j j j j j j j j j j j




associated with vertebral rotation. Which condition will the nurse most likelyfind documented in the

patient’s medical record? j j




a. Scoliosis


b. Arthritis
c. Osteomalacia
d. Osteogenesis j
