Strengthen the muscles while keeping the joints stationary.
Rationale: An exercise program is recommended to strengthen muscles after arthroplasty. Isometric (or muscle-setting) exercises strengthen muscles but keep the joint stationary during the healing process. Isometric exercise costs little in terms of time and money but these are not necessarily primary reasons for using it. Isometric exercises may help improve a client’s morale by promoting self-care but this is not the reason for doing them. Isometric exercise will not help prevent joint stiffness; the joint is kept stationary.
Rationale: Crackles are auscultated over fluid-filled alveoli. Crackles heard on lung auscultation do not have to be associated with cyanosis. Bronchospasm and airway narrowing generally are associated with wheezing sounds.
irrigate the NG tube gently with normal saline solution if ordered.
Rationale: The nurse can gently irrigate the tube if ordered, but must be careful not to reposition it. Repositioning can cause bleeding. The nurse should apply suction continuously — not every hour. The nurse shouldn’t clamp the NG tube postoperatively because secretions and gas will accumulate, stressing the suture line.
