A nurse is preparing to administer warfarin to a client who has chronic atrial fibrillation. Which of the following laboratory values should the nurse monitor prior to administering the medication?

Choice A Reason:
"I will apply heat to my affected ankle to decrease swelling." Heat application is generally not recommended for acute injuries like ankle sprains. Heat can increase blood flow and potentially worsen swelling. Cold therapy (like ice) is typically advised in the early stages to reduce inflammation and swelling.
Choice B Reason:
"I can bear full weight on my affected ankle." For a grade 2 ankle sprain, bearing full weight on the affected ankle might not be advisable initially. Grade 2 sprains involve partial tearing of ligaments and usually require some period of rest or limited weight-bearing to allow healing.
Choice C Reason:
"I can dangle my affected ankle from the edge of the bed. “Dangling the affected ankle from the edge of the bed is a common recommendation to help with gentle movement and improve blood flow without putting excessive stress on the injured ankle. This activity can aid in the recovery process and is often recommended.
Choice D Reason:
"I will wrap my affected ankle with an elastic bandage. “Wrapping the affected ankle with an elastic bandage is a supportive measure recommended for managing ankle sprains. It helps provide compression, support, and stabilization to the injured area, assisting in reducing swelling and providing comfort.

Choice A Reason:

Maintaining skin integrity over the blisters is correct. Blisters form as a protective mechanism for the skin underneath. Popping or breaking blisters increases the risk of infection as it exposes the raw skin to bacteria and other contaminants.

Choice B Reason:

Applying ice to the larger blisters is incorrect.

Reason: Applying ice directly to a burn, especially to blisters, can further damage the skin and exacerbate the injury. Ice can cause additional skin damage and can potentially increase pain and delay healing.

Choice C Reason:

Administering ibuprofen for pain is correct. Ibuprofen is an effective over-the-counter pain reliever that can help manage the discomfort caused by a minor burn. It also has anti-inflammatory properties that can reduce swelling associated with burns.

Choice D Reason:

Running cool water over the affected area is correct. Running cool (not cold) water over the burn helps to cool down the burned area, soothes the pain, and helps prevent further damage to the skin. It's recommended to run water over the burn for around 10-15 minutes to effectively cool the area.

Choice E Reason:

Allowing the affected area to remain open to air is incorrect. Keeping a minor burn uncovered can increase the risk of infection as it exposes the burn to external contaminants. Covering the burn with a sterile, non-stick dressing can protect it from further damage and reduce the risk of infection.
