What is the first intervention of the nurse for changing the dressing to a painful burn?

Choice A rationale:

Irrigating with sterile saline before swabbing can dilute the wound specimen and reduce the accuracy of the culture results. This is because the saline can wash away some of the bacteria that are present in the wound, making it more difficult to identify the specific bacteria that are causing the infection.

Additionally, swabbing the center of the wound may not collect a representative sample of the bacteria present, as bacteria can often be found in higher concentrations at the edges of the wound. This is because the edges of the wound are often where the tissue is most damaged and where the bacteria are able to enter the body more easily.

Choice B rationale:

Obtaining a sample of the drainage from the dressing on the wound may not be as accurate as collecting a sample directly from the wound. This is because the drainage may contain bacteria from the surrounding skin or environment, which could contaminate the culture results.

Additionally, the drainage may not contain a representative sample of the bacteria present in the wound, as some bacteria may not be able to drain out of the wound.

Choice D rationale:

Collecting a tissue sample from the wound during a surgical procedure is the most accurate way to obtain a culture. However, this is not always feasible or necessary.

It is often possible to obtain an accurate culture by collecting a sample from the wound using a sterile swab. This is a less invasive procedure and can be done at the bedside.

Choice A rationale:

A lactose-free diet does not contraindicate acupuncture therapy. Lactose intolerance is a digestive condition that does not affect blood clotting or the ability to receive acupuncture safely.

Acupuncture needles are very fine and do not typically cause bleeding. Even if minor bleeding occurs, it is not a concern for individuals without bleeding disorders.

Therefore, a lactose-free diet does not pose a risk for acupuncture.

Choice B rationale:

Thrombocytopenia is a condition characterized by a low platelet count. Platelets are essential for blood clotting. Acupuncture involves the insertion of needles into the skin. This can cause minor bleeding, even when performed correctly.

In individuals with thrombocytopenia, even minor bleeding can be difficult to control and may lead to excessive bruising or hematoma formation.

Therefore, thrombocytopenia is a contraindication to acupuncture therapy due to the increased risk of bleeding complications.

Choice C rationale:

Herniated lumbar disks are a common condition that can cause back pain. Acupuncture is often used to treat back pain, including pain caused by herniated disks.

Studies have shown that acupuncture can be effective in reducing pain and improving function in patients with herniated disks.

Therefore, the presence of herniated lumbar disks does not contraindicate acupuncture therapy.

Choice D rationale:

Latex and strawberry allergies are not contraindications to acupuncture therapy. Acupuncture needles are typically made of stainless steel, which does not contain latex.

Additionally, acupuncture does not involve the use of strawberries or any other substances that are common allergens. Therefore, latex and strawberry allergies do not pose a risk for acupuncture.
