The nurse has just received a change-of-shift report for 4 clients on the coronary step-down unit. Which client will the nurse assess first?

A. A client who underwent coronary angioplasty yesterday who is requesting to sit in the bedside chair: Sitting in a chair is a routine activity and does not indicate an immediate change in clinical status. While safety and mobility should be assessed, this client is stable and does not require immediate priority over acute symptoms. B. A client with dilated cardiomyopathy who developed dyspnea and agitation 1 hour prior to shift change: Dyspnea and agitation are signs of possible acute decompensated heart failure, hypoxia, or pulmonary edema. These symptoms indicate a potentially life-threatening change in condition and require immediate assessment to ensure airway, breathing, and hemodynamic stability. This client has the highest priority. C. A client who is two days postoperative coronary artery bypass grafting and has a temperature of 100.6°F: A mild postoperative fever is relatively common and may reflect normal inflammatory response. While it should be monitored, it is not immediately life-threatening and is lower priority compared with acute respiratory distress. D. A client with mitral valve stenosis who is scheduled for a balloon valvuloplasty later today: Preoperative assessment and preparation are important, but unless the client is unstable, this is not as urgent as new-onset dyspnea and agitation. Preprocedure evaluation can be addressed after assessing acute changes in other clients.
