Wagner, 6e Chapter 13/Alterations in Cardiac Output End of Chapter NCLEX 1. A client is admitted with newly diagnosed aortic valve stenosis. The nurse closely monitors this client for development ... of which cardiac dysrhythmia that may cause immediate decompensation? 1. Premature ventricular contractions 2. Premature atrial contractions 3. Atrial fibrillation 4. Sinus bradycardia Answer: 3 Rationale: 1. While development of PVCs may decrease cardiac output, decompensation would not be immediate. 2. Premature atrial contractions will cause some decrease in cardiac output, particularly if they occur frequently. However, decompensation will not be immediate. 3. When a client with aortic valve stenosis develops atrial fibrillation, atrial contractions are not effective. This results in immediate decompensation from reduced cardiac output. 4. If sinus bradycardia is slow enough, decompensation will occur. However, this is true of all clients and is not limited to those with aortic stenosis. Cognitive level: Analyzing Nursing Process: Assessment Client Need: Physiological Integrity/Physiological Adaptation LO #12. A client has been diagnosed with infective endocarditis. Which teaching information should the nurse provide to this client? (Select all that apply.) 1. “You will probably be on antibiotic therapy for at least two weeks.” 2. “Infective endocarditis usually affects the muscle in the wall of your heart.” 3. “Most people who develop infective endocarditis are smokers.” 4. “It is very important that you take your antibiotics on time and according to the directions provided.” 5. “You will have several blood tests done to determine which antibiotic is necessary.” Answer: 4, 5 Rationale: 1. Antibiotic therapy for infective endocarditis generally lasts at least six weeks if not longer. 2. Infective endocarditis affects the valves of the heart. 3. Infective endocarditis is most often associated with preexisting heart disease and physiological states that decrease the immune status. Examples are extremes of age, surgery, and IV drug use.
