The nurse is caring for a client in the telemetry unit and notices the rhythm below. The client is unresponsive and pulseless. After calling for assistance, what should be the nurse's next action?

A. Teach the client how to change the pacemaker dressing: Client education is important but not a priority in the immediate post-procedure phase. Dressing changes should initially be performed using sterile technique by clinical staff to prevent infection at the insertion site.

B. Immobilize the affected arm using a sling: After pacemaker insertion, the affected arm (usually on the side of the implantation) should be immobilized or limited in movement to prevent lead dislodgment. Elevating the arm above the shoulder or excessive motion can compromise pacemaker lead placement during the early healing period.

C. Arrange for ancillary personnel to feed the client: Assistance with feeding is only necessary if the client has physical or cognitive limitations. This is not a routine or priority intervention following pacemaker insertion unless clinically indicated by other assessments.

D. Monitor urine output every two hours: Frequent monitoring of urine output is not directly related to pacemaker insertion unless there are other concerns such as fluid imbalance or renal dysfunction. It's not a standard intervention in the immediate care plan for this procedure.

A. Increase in systolic blood pressure 10 mmHg above client's norm: A mild increase in systolic blood pressure is not a specific indicator of mitral stenosis progression. Blood pressure fluctuations may occur due to various factors and are not typically used as a primary marker of worsening valve disease.

B. reports dyspnea after walking up 2 flights of stairs: Exertional dyspnea is a common early symptom of mitral stenosis due to reduced left atrial emptying and pulmonary congestion. However, this does not necessarily indicate worsening unless the symptom becomes more severe or occurs with minimal exertion.

C. Jugular vein distention and +3 peripheral edema: These are signs of right-sided heart failure, which may result from long-standing mitral stenosis leading to pulmonary hypertension and subsequent right ventricular hypertrophy and failure. This indicates disease progression and worsening cardiac function.

D. Complaints of epigastric pain after eating a large meal: Epigastric discomfort is not a typical symptom of mitral stenosis and is more likely related to gastrointestinal issues. It does not reflect the status or progression of the cardiac condition.
