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. Weight loss while using a diaphragm is not typically an urgent concern and may be related to dieting; the client should be advised to follow up with her primary care provider for further

evaluation.

B. Cramping and bleeding are common side effects following an IUD insertion and typically do not require immediate attention unless severe or accompanied by other concerning symptoms;

the client should be advised to monitor her symptoms and follow up if they worsen.

C. Breakthrough bleeding is a common side effect of starting oral contraceptives and may resolve on its own after a few cycles; the client should be advised to continue taking her pills as prescribed and to follow up if the bleeding persists or worsens.

D. Shoulder pain following a laparoscopic procedure may indicate a potential complication such as referred pain from gas used during the procedure or more serious issues such as internal bleeding or organ injury; the client should be instructed to come to the clinic for further

evaluation and management.

A. Apply oxygen at 3 L/min per nasal cannula: While oxygenation is important, there is no

indication in the scenario that the client requires oxygen supplementation at this time. Checking oxygen saturation would be more relevant if there were respiratory concerns.

B. Review the chest x-ray report: This is the most appropriate action before initiating the IV

infusion to ensure proper placement of the central venous catheter and absence of complications such as pneumothorax or malposition.

C. Flush the catheter with sterile water: Flushing the catheter with sterile water is not necessary before starting the infusion, especially without confirming proper catheter placement through chest x-ray.

D. Obtain a peripheral blood glucose level: While monitoring blood glucose levels may be

important in certain clinical situations, it is not directly relevant to initiating an IV infusion of Ringer's lactate via a central venous catheter.
