A nurse is interpreting the cardiac rhythm strip of a client who was admitted with syncope.
Which of the following images indicates that the client has atrial fibrillation?

A. Constipation: While constipation can be uncomfortable, it is not typically considered an immediate threat to a patient's health in a cardiac unit setting. It requires assessment and intervention but is not the highest priority.

B. Indigestion can be a subtle symptom of myocardial infarction (MI) or acute coronary syndrome (ACS), particularly in older adults, women, or clients with diabetes. Clients experiencing "indigestion" may be describing chest discomfort, which requires immediate assessment to rule out a cardiac event. Early identification and intervention for cardiac symptoms are critical to prevent further complications.

C. Swollen ankles can indicate fluid retention, which is a common sign of heart failure. While this symptom requires attention, it does not typically indicate an immediate life-threatening issue compared to potential cardiac ischemia associated with "indigestion."

D. Urinary frequency: This could be related to medications or other conditions. While it should be addressed, it is not the most critical issue compared to potential acute cardiac symptoms.

A. Taking the client to the bathroom after administering a preoperative sedative increases the risk of falls.
B. Surgical site verification should be completed before administering the preoperative medication.
C. Teaching should be done before giving the medication, as the sedative may impair learning and recall.
D. Raising the side rails helps ensure client safety by preventing falls after the medication has been administered.
