It is important to disregard their current interests in favor of exercise.! c.! No physical benefit can be gained without a formal exercise program.! d.! Adjustments to exercise programs may have to be made to prevent problems.! ! !! ANS: D! Exercise is extremely beneficial for older adults, but adjustments to an exercise program may have to be made for those of advanced age to prevent problems.

When developing an exercise program for any older adult, consider not only the person’s current activity level, range of motion, muscle strength and tone, and response to physical activity, but also the person’s interests, capacities, and limitations. Older adults who are unable to participate in a formal exercise program are able to achieve the benefits of improved joint mobility and enhanced circulation by simply stretching and exaggerating movements during performance of routine activities of daily living.! !!

The recommended frequency of workouts should be twice a day.! c.! An exercise prescription should incorporate aerobic exercise only.! d.! The purpose of weight training is to bulk up muscles.! ! !! ANS: A! A sedentary lifestyle contributes to the development of health-related problems.

A holistic approach is taken to develop overall fitness and includes warm-ups, aerobic exercise, resistance training, weight training, and so forth. The recommended frequency of aerobic exercise is 3 to 5 times per week or every other day for approximately 30 minutes. Crosstraining is recommended for the patient who prefers to exercise every day. Some patients use weight training to bulk up their muscles. However, the purposes of weight training from a health perspective are to develop tone and strength and to simulate and maintain healthy bone.! !! DIF: Understand! REF:! 796-797! ! OBJ:!

Allows the body to readjust gradually to baseline functioning.! b.! Prepares the body and decreases the potential for injury.! c.! Should not involve stretching exercises because they can lead to injury.! d.!

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. It usually lasts about 5 to 10 minutes and may include stretching, calisthenics, and/or aerobic activity performed at a lower intensity. The cool-down period 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.! !!

TOP:! Assessment! MSC:! Teaching/Learning! ! ! ! Many patients find it difficult to incorporate an exercise program into their daily lives because of time constraints. For these patients, it is beneficial to reinforce that many ADLs are used to accumulate the recommended 30 minutes or more per day of moderate-intensity physical activity. When instructing these patients, the nurse explains that! ! 14.! a.! Housework is not considered an aerobic exercise.! b.! To strengthen back muscles, the patient should bend using back muscles.! c.! Daily chores should begin with gentle stretches.! d.!

The patient should stick to one chore until it is done before beginning a new one.! ! !! ANS: C! Daily chores should begin with gentle stretches. Housework is considered aerobic exercise. To make it more aerobic, work faster and scrub harder. Bend your legs rather than your back to prevent back injury. Alternate cleaning activities to prevent overworking the same muscle groups.! !!

The nurse is developing an exercise plan for someone diagnosed with congestive heart failure and exercise intolerance. In doing so, the nurse should! ! a.! Plan for 20 minutes of continuous aerobic activity and increase as tolerated.! b.! Perform 6-minute walks at the patient’s pace at least 2 times a day.! c.! Instruct the patient that he should not take his beta blocker medication on exercise days.! d.! Encourage a high-calorie diet to plan for extra calorie expenditure.! ! !! ANS: B! For the diagnosis of exercise intolerance, the patient should begin by performing 6minute walks at his own pace at least twice a day.

The patient would not be able to tolerate 20 minutes of continuous aerobic activity. Patients should be instructed to take medications as ordered. Low-calorie, low-sodium, and high-protein diets are best for this type of patient.! !! DIF: Apply! REF:! 755! ! OBJ:!

Teaching/Learning! ! ! Which of the following exercise activities would most likely provide the opportunity for mind-body awareness?! 16.! a.! Warm-up activity! b.! Resistance training! c.! Aerobic exercise! d.! Cool-down activity! ! !! ANS: D! The cool-down period allows the body to readjust gradually to baseline functioning and provides an opportunity to combine movement such as stretching with relaxationenhancing mind-body awareness. The warm-up activity prepares the body and decreases the potential for injury. Aerobic exercise includes running, bicycling, jumping rope, and so forth, and is the main portion of exercise activity; it precedes the cool-down period.

Resistance training increases muscle strength and endurance and is associated with improved performance of daily activities but not with enhancing mind-body awareness.! !! DIF: Analyze! REF:! 757! ! OBJ:! Describe important factors to consider when planning an exercise program for patients across the life p and for those with specific chronic illnesses.! TOP:! Evaluation! MSC:! Teaching/Learning! ! ! The patient is brought to the emergency department with possible injury to his shoulder. To help determine the degree of injury, the nurse should evaluate! ! 17.! a.!

The patient’s gait.! b.! The patient’s range of motion.! c.! Fine motor coordination.! d.! Activity tolerance.! ! !! ANS: B! Assessing range of motion is one assessment technique used to determine the degree of damage or injury to a joint. Gait is the manner or style of walking. It may have little bearing on the shoulder damage. Assessing fine motor coordination would be beneficial in helping to assess the patient’s ability to perform tasks but would not help in evaluating the shoulder. Activity tolerance refers to the type and amount of exercise or activity a person is able to perform.

Damage to the shoulder would affect this, but this would not have a direct bearing on the amount of damage done to the shoulder.! !! DIF: Apply! REF:! 752-753! ! OBJ:!

Joint motion is greater than normal.! c.!

The patient has arthritis.! d.! The elbow cannot be moved (frozen).! ! !! ANS: B! Increased mobility (beyond normal) of a joint may indicate connective tissue disorders, ligament tears, or possible joint fractures. Limited range of motion often indicates inflammation such as arthritis, fluid in the joint, altered nerve supply, or contractures (frozen joints).! !! DIF: Analyze! REF:! 752-753! ! OBJ:! Assess patients for impaired mobility and activity intolerance.! TOP:! Evaluation! MSC:! Teaching/Learning! ! ! ! The patient has been bedridden for several months owing to severe congestive heart disease.

In determining a plan of care for this patient that will address his activity level, the nurse formulates which of the following nursing diagnoses?! ! 19.! a.! Fatigue related to poor physical condition! b.! Impaired gas exchange related to decreased cardiac output! c.! Decreased cardiac output related to decreased myocardial contractility! d.! Activity intolerance related to physical deconditioning! ! !! ANS: D! When activity and exercise are problems for a patient, nursing diagnoses often focus on the individual’s ability to move. The diagnostic label directs nursing interventions.

In this case, physical deconditioning must be addressed relative to activity level, perhaps leading to 6-minute walks twice a day. Physical deconditioning is the cause of fatigue as well, so it would take priority over that diagnosis. Decreased cardiac output and myocardial contractility are serious concerns that must be addressed before activity intolerance to keep the patient safe and to help determine the level of exercise that the patient can tolerate, but reconditioning of the patient’s body will help improve contractility and cardiac output.! !!

Formulate nursing diagnoses for patients experiencing problems with impaired mobility and activity intolerance.! TOP:! Implementation!! MSC:! Teaching/Learning! ! The patient weighs 450 lbs (204. 5 kg) and complains of shortness of breath with any exertion. His health care provider has recommended that he begin an exercise program. He states that he can hardly get out of bed and just cannot do anything around the house. To focus on the cause of the patient’s complaints, the nurse devises which of the following nursing diagnoses?! ! 20.! a.! Activity intolerance related to excessive weight! .! Activity intolerance related to bed rest! c.! Impaired gas exchange related to shortness of breath! d.! Imbalanced nutrition: less than body requirements! ! !! ANS: A! The diagnostic label directs nursing interventions. This requires the correct selection of related factors. For example, Activity intolerance related to excess weight gain requires very different interventions than if the related factor is prolonged bed rest. In this case, the intolerance is related to the patient’s excessive weight. He is not on bed rest, although he claims that it is difficult for him to get out of bed.

Shortness of breath is a symptom, not a cause, of Impaired gas exchange, making this nursing diagnosis ineffective. The patient certainly has an imbalance of nutrition, but it is more than body requirements.! !! DIF: Apply! REF:! 753! ! OBJ:!

Range-of-motion exercises should be started 2 days after the patient is stable.! d.!

Range-of-motion exercises should be done on major joints only.! ! !! ANS: B! When patients cannot participate in active range of motion, the nurse must institute passive range of motion to maintain joint mobility and prevent contractures. Passive range of motion can be substituted for active when needed. For the patient who does not have voluntary motor control, passive range-of-motion exercises are the exercises of choice. Unless contraindicated, the nursing care plan includes exercising each joint (not just major joints) through as nearly a full range of motion as possible.

Initiate passive range-of-motion exercises as soon as the patient loses the ability to move the extremity or joint.! !! DIF: Understand! REF:! 759! ! OBJ:!

Some patients experience orthostatic hypotension—a drop in blood pressure that occurs when the patient changes from a horizontal to a vertical position. Assist the patient to a position of sitting at the side of the bed, and dangle for 1 to 2 minutes before standing. The nurse needs to provide support at the waist so that the patient’s center of gravity remains midline. This is achieved with the use of a gait belt. A gait belt encircles the patient’s waist and may have handles attached for the nurse to hold while the patient ambulates.

In the discussion of body mechanics, two of these functions —support and movement—are most important. In support, bones serve as the framework and contribute to the shape, alignment, and positioning of body parts. In movement, bones together with their joints constitute levers for muscle attachment. As muscles contract and shorten, they pull on bones, producing joint movement. Protection involves encasing the soft tissue organs in a protective cage. Mineral storage helps to strengthen bones but also helps regulate blood levels of certain nutrients. Hematopoiesis is the formation of blood cells.! !! DIF: Remember!
