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. Serum calcium levels are not directly indicative of hypervolemia.

B. A urine specific gravity of 1.001 indicates dilute urine, which is a common finding in hypervolemia as the kidneys attempt to excrete excess fluid.

C. Serum sodium levels within the normal range (e.g., 138 mEq/L) are not indicative of hypervolemia.

D. Urine pH of 6.1 is within the normal range and does not specifically indicate hypervolemia.

A. Set up the sterile field 7.6 cm (3 in) below waist level - While it's important to maintain a sterile field, the specific height mentioned is not a standard requirement.

B. Hold the bottle of sterile solution with the palm over the label while pouring - This is

incorrect because it increases the risk of contaminating the solution by touching the label.

C. Place the sterile items within 1 cm (0.4 in) of the edge of the sterile border - This is the correct action as it ensures that sterile items are easily accessible without reaching over the sterile field, minimizing the risk of contamination.

D. Place the lid of a bottle of sterile solution within the sterile field - Placing the lid inside the sterile field increases the risk of contamination, as the lid is not considered sterile.
