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. A metallic taste in the mouth is a common side effect of the contrast dye used in IV urography procedures and is not typically a cause for concern.

B. Abdominal fullness may occur due to the administration of fluids during the procedure and is not usually a priority finding unless it persists or is severe.

C. Feeling flushed and warm may be a transient reaction to the contrast dye and does not typically require immediate intervention unless accompanied by other symptoms.

D. Swollen lips could indicate an allergic reaction to the contrast dye, which can progress rapidly and potentially lead to a severe reaction such as anaphylaxis. This is the priority finding requiring immediate attention.

A. Adjusting the straps on the harness once per week is not recommended. The straps should only be adjusted by a healthcare provider to ensure proper fit and alignment, as incorrect adjustments can compromise the effectiveness of the treatment.

B. Using ultra-thin diapers applied over the straps is incorrect. Diapers should be placed under the harness to prevent soiling and maintain the harness's effectiveness. Placing diapers over the straps can interfere with proper positioning.

C. Maintaining the child in a prone position while the harness is in place is not necessary. The Pavlik harness is designed to keep the hips in a flexed and abducted position, and the infant can remain in various positions that are comfortable and safe.

D. Gently massaging the skin under the straps once per day is correct. This helps prevent skin irritation and promotes circulation. Guardians should also check for redness or irritation and ensure the harness fits properly to avoid pressure injuries.
