A nurse is admitting a client who has a history of atrial fibrillation. Which of the following conditions should the nurse recognize atrial fibrillation places the client at risk for?

Rationale:
A. The client takes multiple steps while holding the walker: Taking several steps while holding the walker increases the risk of imbalance and falls. The correct technique is to move the walker forward one step length, ensure all four legs are stable on the ground, and then take a single step toward it before moving the other leg.

B. The client lifts the walker as it is moved forward: The walker should be lifted slightly and placed firmly on the ground to ensure stability with each step. Sliding the walker instead of lifting it can cause uneven movement or tipping, especially on rough surfaces, making lifting the correct method.

C. The client advances the walker and takes a step towards it: This is the proper technique for safe use. The client should advance the walker first, then step forward with the weaker leg, followed by the stronger leg, maintaining balance and even weight distribution.

D. The client grasps the walker by the hand grips on the upper bars: Proper hand placement on the upper hand grips ensures stability and correct posture during ambulation. Holding the walker anywhere else can cause poor control, imbalance, or wrist strain.

Rationale:
A. Elevate the affected forearm with pillows: Elevation helps reduce swelling and promotes venous return, which is critical in the immediate management of a fracture to prevent complications such as increased edema or impaired circulation.

B. Administer Ibuprofen 200 mg PO: The child reports pain at a level of 5, meeting the prescription threshold. Administering analgesia promptly helps manage discomfort and supports cooperation with further interventions, such as casting.

C. Place a nonadherent dressing on the right knee abrasion: While wound care is important, the abrasion is minor and not the most urgent concern. Prioritization focuses on the fractured limb and pain management.

D. Review cast care instructions with the child's parents: Education is important but is not the immediate priority before the cast is applied. It can be provided after the child is stabilized and pain is managed.

E. Explain the cast application procedure to the child: While preparing the child psychologically is important, immediate interventions to reduce pain and swelling take precedence over anticipatory teaching.

F. Apply ice packs to the fingers and along the right forearm: Ice helps reduce swelling and pain in the acute phase of the fracture. Applying ice in combination with elevation supports circulation and comfort while awaiting casting.
