Metformin A client who had cardiac surgery 24 hours ago has had a urine output averaging 20 mL/hour for 2 hours. The client received a single bolus of 500 mL of intravenous fluid. Urine output for the subsequent hour was 25 mL. Daily laboratory results indicate that the blood urea nitrogen level is 45 mg/dL (16 mmol/L) and the serum creatinine level is 2.2 mg/dL (194 mcmol/L). On the basis of these findings, the nurse would anticipate that the client is at risk for which problem? Acute Kidney Injury The nurse is reviewing an electrocardiogram rhythm strip. The P waves and QRS complexes are regular. The PR interval is 0.16 seconds, and QRS complexes measure 0.06 seconds. The overall heart rate is 64 beats/minute. Which action should the nurse take? Continue to monitor A client is wearing a continuous cardiac monitor, which begins to sound its alarm. The nurse sees no electrocardiographic complexes on the screen. Which is the priority nursing action? Check the client's status and lead placement. The nurse is evaluating a client's response to cardioversion. Which assessment would be the priority? Status of airway The nurse is caring for a client who has just had implantation of an automatic internal cardioverter-defibrillator. The nurse should assess which item based on priority? Activation status of the device, heart rate cutoff, and number of shocks it is programmed to deliver A client's electrocardiogram strip shows atrial and ventricular rates of 110 beats/minute. The PR interval is 0.14 seconds, the QRS complex measures 0.08 seconds, and the PP and RR intervals are regular. How should the nurse correctly interpret this rhythm? Sinus tachycardia The nurse is assessing the neurovascular status of a client who returned to the surgical nursing unit 4 hours ago after undergoing aortoiliac bypass graft. The affected leg is warm, and the nurse notes redness and edema. The pedal pulse is palpable and unchanged from admission. How should the nurse correctly interpret the client's neurovascular status? The neurovascular status is normal because of increased blood flow through the leg. The nurse is evaluating the condition of a client after pericardiocentesis performed to treat cardiac tamponade. Which observation would indicate that the procedure was effective? A rise in blood pressure A client with variant angina is scheduled to receive an oral calcium channel blocker twice daily. Which statement by the client indicates the need for further teaching? "My spouse told me that since I have developed this problem, we are going to stop walking in the mall every morning." The nurse is monitoring a client with acute pericarditis for signs of cardiac tamponade. Which assessment finding indicates the presence of this complication? Muffled or distant heart sounds The home care nurse is providing instructions to a client with an arterial ischemic leg ulcer about home care management and self-care management.

Stop smoking because it causes cutaneous blood vessel spasm The nurse is developing a plan of care for a client with varicose veins in whom skin breakdown occurred over the varicosities as a result of secondary infection. Which is a priority intervention? Elevate the legs higher than the heart The nurse in the medical unit is reviewing the laboratory test results for a client who has been transferred from the intensive care unit (ICU). The nurse notes that a cardiac troponin T assay was performed while the client was in the ICU. The nurse determines that this test was performed to assist in diagnosing which condition? Myocardial infarction The nurse is caring for a client with cardiac disease who has been placed on a cardiac monitor. The nurse notes that the client has developed atrial fibrillation and has a rapid ventricular rate of 150 beats/minute. The nurse should next assess the client for which finding? Hypotension The nurse is performing an assessment on a client with a diagnosis of left-sided heart failure. Which assessment component would elicit specific information regarding the client's left-sided heart function? Listening to lung sounds The nurse is participating in a class on rhythm strip interpretation. Which statement by the nurse indicates an understanding of a PR interval of 0.20? "This is a normal finding." The nurse in the medical unit is assigned to provide discharge teaching to a client with a diagnosis of angina pectoris. The nurse is discussing lifestyle changes that are needed to minimize the effects of the disease process. The client continually changes the subject during the teaching session. The nurse interprets that this client's behavior is most likely related to which problem?
