A nurse in a pediatric unit is caring for a group of clients. For which of the following diseases should the nurse implement droplet precautions?

- A: An INR of 1.1 is within the normal range, indicating normal blood clotting ability, which is essential for wound healing. A normal INR does not pose a risk for delayed wound healing.
- B: Hyperemesis can lead to dehydration and malnutrition, both of which are detrimental to wound healing. Dehydration reduces blood volume and flow, impairing the delivery of oxygen and nutrients to the wound site, while malnutrition can weaken the immune response and the formation of new tissue.
- C: An HbA1C level of 5.6% is at the high end of the normal range and does not typically indicate diabetes or impaired glucose control, which are risk factors for delayed wound healing.
- D: While uncontrolled pain can be a concern for patient comfort and may indirectly affect wound healing by reducing mobility, it is not a direct risk factor for delayed wound healing like hyperemesis is.

A. Povidone-iodine may be used as a wound cleanser, but the method described here (using cotton balls) is not typically recommended as it can leave fibers in the wound.

B. Administering oral analgesia prior to wound irrigation may be appropriate for pain management but is not directly related to understanding wound irrigation technique.

C. Warming irrigation solution in a microwave oven can lead to uneven heating and potential tissue damage. This method is not recommended for warming irrigation solution.

D. Irrigating the wound from the top to the bottom ensures that contaminants are flushed away from the wound site, reducing the risk of infection and promoting healing. This indicates an understanding of proper wound irrigation technique.
