TB Ch: 39 - Activity and Exercise Flashcards
A nurse observes a patient rising from a chair slowly by pushing on the chair arms. Which type of tension and contraction did the nurse observe?
a. Eccentric tension and isotonic contraction
b. Eccentric tension and isometric contraction
c. Concentric tension and isotonic contraction
d. Concentric tension and isometric contraction
ANS: A
This movement causes eccentric tension and isotonic contraction. Eccentric tension helps control the speed and direction of movement. For example, when using an overhead trapeze, the patient slowly lowers himself to the bed. The lowering is controlled when the antagonistic muscles lengthen. By pushing on the chair arms and rising eccentric tension and isotonic contraction occurred. In concentric tension, increased muscle contraction causes muscle shortening, resulting in movement such as when a patient uses an overhead trapeze to pull up in bed. Concentric and eccentric muscle actions are necessary for active movement and therefore are referred to as dynamic or isotonic contraction. Isometric contraction (static contraction) causes an increase in muscle tension or muscle work but no shortening or active movement of the muscle (e.g., instructing the patient to tighten and relax a muscle group, as in quadriceps set exercises or pelvic floor exercises).
A nurse notices that a patient has a structural curvature of the spine associated with vertebral rotation. Which condition will the nurse most likely find documented in the patient’s medical record?
a. Scoliosis
b. Arthritis
c. Osteomalacia
d. Osteogenesis
ANS: A
Scoliosis is a structural curvature of the spine associated with vertebral rotation. Osteogenesis imperfecta is an inherited disorder that makes bones porous, short, bowed, and deformed. Osteomalacia is an uncommon metabolic disease characterized by inadequate and delayed mineralization, resulting in compact and spongy bone. Arthritis is an inflammatory joint disease characterized by inflammation or destruction of the synovial membrane and articular cartilage and by systemic signs of inflammation.
A nurse is caring for a patient who has some immobility from noninflammatory joint degeneration. The nurse is teaching the patient about this process. Which information will the nurse include in the teaching session?
a. This will affect synovial fluid.
b. This will affect the body systemically.
c. This involves mostly non–weight-bearing joints.
d. This involves overgrowth of bone at the articular ends.
ANS: D
Joint degeneration, which can occur with inflammatory and noninflammatory disease, is marked by changes in articular cartilage combined with overgrowth of bone at the articular ends. Degenerative changes commonly affect weight-bearing joints. Synovial fluid is normal in noninflammatory diseases. Inflammatory joint disease (e.g., arthritis) is characterized by inflammation or destruction of the synovial membrane and articular cartilage and by systemic signs of inflammation.
The nurse is providing care to a patient who is bedridden. The nurse raises the height of the bed. What is the rationale for the nurse’s action?
a. Narrows the nurse’s base of support.
b. Allows the nurse to bring feet closer together.
c. Prevents a shift in the nurse’s base of support.
d. Shifts the nurse’s center of gravity farther away from the base of support.
ANS: C
Raising the height of the bed when performing a procedure prevents bending too far at the waist and shifting the base of support. Balance is maintained by proper body alignment and posture through two simple techniques. First, widen the base of support by separating the feet to a comfortable distance. Second, increase balance by bringing the center of gravity closer to the base of support.
A nurse is following the no-lift policy when working to prevent personal injury. Which type of personal back injury is the nurse most likely trying to prevent?
a. Thoracic
b. Cervical
c. Lumbar
d. Sacral
ANS: C
The most common back injury for nurses is strain on the lumbar muscle group, which includes the muscles around the lumbar vertebrae. While cervical, thoracic, and sacral can occur, lumbar is the most common.
The nurse is caring for a patient in the emergency department with an injured shoulder. Which type of joint will the nurse assess?
a. Fibrous
b. Synovial
c. Synergistic
d. Cartilaginous
ANS: B
Synovial joints, or true joints, such as the hinge type at the elbow, are freely movable and the most mobile, numerous, and anatomically complex body joints. Fibrous joints fit closely together and are fixed, permitting little, if any, movement such as the syndesmosis between the tibia and the fibula. Synergistic is a type of muscle, not joint. Cartilaginous joints have little movement but are elastic and use cartilage to unite separate bony surfaces such as the synchondrosis that attaches the ribs to the costal cartilage.
The nurse is caring for a patient with inner ear problems. Which goal is the priority?
a. Maintain balance.
b. Maintain proprioception.
c. Maintain muscle strength.
d. Maintain body alignment.
ANS: A
Within the inner ear are the semicircular canals, three fluid-filled structures that help maintain balance. Proprioception is the awareness of the position of the body and its parts, and proprioceptors are located on nerve endings, not the inner ear. Muscle strength is maintained with activity and exercise. Although body alignment is important, it is not maintained by the inner ear.
A nurse is teaching a health promotion class about isotonic exercises. Which types of exercises will the nurse give as examples?
a. Swimming, jogging, and bicycling
b. Tightening or tensing of muscles without moving body parts
c. Quadriceps set exercises and contraction of the gluteal muscles
d. Push-ups, hip lifting, pushing feet against a footboard on the bed
ANS: A
Examples of isotonic exercises are walking, swimming, dance aerobics, jogging, bicycling, and moving arms and legs with light resistance. Isometric exercises involve tightening or tensing of muscles without moving body parts. Examples include quadriceps set exercises and contraction of the gluteal muscles. Examples of resistive isometric exercises are push-ups and hip lifting, as well as placing a footboard on the foot of the bed for patients to push against with their feet.
An adolescent tells the nurse that a health professional said the fibrous tissue that connects bone and cartilage was strained in a sporting accident. On which structure will the nurse focus an assessment?
a. Tendon
b. Ligament
c. Synergistic muscle
d. Antagonistic muscle
ANS: B
Ligaments are white, shiny, and flexible bands of fibrous tissue that bind joints and connect bones and cartilage. Tendons are strong, flexible, and inelastic as they serve to connect muscle to bone. Muscles attach bone to bone. Synergistic muscles contract to accomplish the same movement. Antagonistic muscles cause movement at the joint.
A nurse is developing an exercise plan for a middle-aged patient. In which order will the nurse instruct the patient to execute the plan, beginning with the first step?
- Design the fitness program.
- Assemble equipment.
- Assess fitness level.
- Monitor progress.
- Get started.
a. 5, 1, 3, 2, 4
b. 1, 2, 3, 5, 4
c. 2, 5, 3, 1, 4
d. 3, 1, 2, 5, 4
ANS: D
Five steps to beginning an exercise program are Step 1: Assess fitness level; Step 2: Design the fitness program; Step 3: Assemble equipment; Step 4: Get started; and Step 5: Monitor progress.
The nurse gives instructions to a nursing assistive personnel (NAP) regarding exercise for a patient. Which action by the NAP indicates a correct understanding of the directions?
a. Determines the patient’s ability to exercise
b. Teaches the patient how to do the exercises
c. Reports the patient got dizzy after exercising
d. Advises the patient to work through the pain
ANS: C
The NAP notifies the nurse if a patient reports increased fatigue, dizziness, or light-headedness when obtaining preexercise and/or postexercise vital signs. The nurse first must assess the patient’s ability and tolerance to exercise. The nurse also teaches patients and their families how to implement exercise programs. The NAP can prepare patients for exercise (e.g., putting on shoes and clothing, providing hygiene needs, and obtaining preexercise and postexercise vital signs). The NAP can help the patient exercise.
The nurse is starting an exercise program in a local community as a health promotion project. Which information will the nurse include in the teaching session?
a. A cool-down period lasts about 5 to 10 minutes.
b. The purpose of weight training is to bulk up muscles.
c. Resistance training is appropriate for warm-up and cool-down periods.
d. Aerobic exercise should be done 3 to 5 times per week for about 20 minutes.
ANS: A
The cool-down period follows the exercise routine and usually lasts about 5 to 10 minutes. The purposes of weight training from a health perspective are to develop tone and strength and to simulate and maintain healthy bone. Stretching and flexibility exercises are ideal for warm-up and cool-down periods. The recommended frequency of aerobic exercise is 3 to 5 times per week or every other day for approximately 30 minutes.
The patient is eager to begin an exercise program with a 2-mile jog. The nurse instructs the patient to warm up. The patient does not want to waste time with a “warm-up.” Which information will the nurse share with the patient?
a. The warm-up in this case can be done after the 2-mile jog.
b. The warm-up prepares the body and decreases the potential for injury.
c. The warm-up allows the body to readjust gradually to baseline functioning.
d. The warm-up should be performed with high intensity to prepare for the coming challenge.
ANS: B
The warm-up activity prepares the body for activity and decreases the potential for injury and should not be omitted. It usually lasts about 5 to 10 minutes and may include stretching, calisthenics, and/or aerobic activity performed at a lower intensity. The warm-up is before the exercise, while the cool-down period is after the exercise. The cool-down, not the warm-up, allows the body to readjust gradually to baseline functioning and provides an opportunity to combine movement such as stretching with relaxation-enhancing mind-body awareness. The warm-up should not be a high-intensity workout.
The nurse is caring for a patient who cannot bear weight but needs to be transferred from the bed to a chair. The nurse decides to use a transportable hydraulic lift. What will the nurse do?
a. Place a horseshoe-shaped base on the opposite side from the chair.
b. Remove straps before lowering the patient to the chair.
c. Hook longer straps to the bottom of the sling.
d. Attach short straps to the bottom of the sling.
ANS: C
The nurse should attach the hooks on the strap to the holes in the sling. Short straps hook to top holes of the sling; longer straps hook to the bottom of the sling. The horseshoe-shaped base goes under the side of the bed on the side with the chair. Position the patient and lower slowly into the chair in accordance with manufacturer guidelines to safely guide the patient into the back of the chair as the seat descends; then remove the straps and the mechanical/hydraulic lift.
The nurse is preparing to move a patient to a wheelchair. Which action indicates the nurse is following recommendations for safe patient handling?
a. Mentally reviews the transfer steps before beginning
b. Uses own strength to transfer the patient
c. Focuses solely on body mechanics
d. Bases decisions on intuition
ANS: A
Safe patient handling includes mentally reviewing the transfer steps before beginning the procedure to ensure both the patient’s and your safety. Use the patient’s strength when lifting, transferring, or moving when possible. Body mechanics alone do not protect the nurse from injury to the musculoskeletal system when moving, lifting, or transferring patients. After completing the assessment, nurses use an algorithm to guide decisions about safe patient handling.
