Acquired disease of the heart valves can be a major clinical problem frequently requiring surgical correction. Of the four cardiac valves, the aortic and mitral valves most commonly are involved. Structural changes in the tricuspid valve can occur, but the leading causes of tricuspid valvular disease are changes secondary to left-sided heart failure and pulmonary hypertension secondary to valvular disease of the aortic or mitral valve. Onset of symptoms can be quite sudden (Case 2) when attribut- able to acute changes in structural anatomy of the valve (endocardi- tis, aortic dissection, and ruptured papillary muscle or chordae tendinae). More often, patients present with progressive symptoms, although an acute episode of heart failure or pulmonary edema may draw attention to the disease process. In either situation, proper workup and appropriate medical and surgical therapy are crucial to the long- and short-term well-being of the patient. They come within greatest approximation at the noncoronary sinus of the aortic valve: the ante- rior leaflet of the mitral valve can be viewed, at the time of aortic valve surgery, as lying just below the noncoronary sinus. The normal aortic valve is a three-leaflet structure consisting of the 2 left, right, and noncoronary leaflets.

Specific nursing measures include the following: Assessing all body surfaces and documenting skin integrity every 8 hours Turning and repositioning the patient every 2 hours Providing skin care every 4 hours Assisting the patient to get out of bed to a chair three times a day Improving Cognitive Functioning Although many patients with head injury survive because of resuscitative and supportive technology generic accutane 10mg on-line acne ziana, they frequently have significant cognitive sequelae that may not be detected during the acute phase of injury purchase accutane 20 mg free shipping skin care vitamin c. Cognitive impairment includes memory deficits, decreased ability to focus and sustain attention to a task (distractibility), reduced ability to process information, and slowness in thinking, perceiving, communicating, reading, and writing. Psychiatric, emotional, and relationship problems develop in many patients after head injury (Hsueh-Fen & Stuifbergen, 2004). Resulting psychosocial, behavioral, emotional, and cognitive impairments are devastating to the family as well as to the patient. A neuropsychologist (specialist in evaluating and treating cognitive problems) plans a program and initiates therapy or counseling to help the patient reach maximal potential (Eslinger, 2002). Cognitive rehabilitation activities help the patient to devise new problem-solving strategies. The retraining is carried out over an extended period and may include the use of sensory stimulation and reinforcement, behavior modification, reality orientation, computer-training programs, and video games. Even if intellectual ability does not improve, social and behavioral abilities may. The patient recovering from a traumatic brain injury may experience fluctuations in the level of cognitive function, with orientation, attention, and memory frequently affected. Many types of sensory stimulation programs have been tried, and research on these programs is ongoing (Davis & Gimeniz, 2004).
