Which herbal supplement is likely to exacerbate symptoms for a patient with rheumatoid arthritis?

Choice A rationale:

A patient's last bowel movement being 4 days ago does not directly increase their risk of pulmonary embolism (PE). While constipation can be a risk factor for deep vein thrombosis (DVT), which can lead to PE, it is not a significant risk factor on its own.

It's important to assess for other risk factors for DVT, such as immobility, recent surgery, or a history of blood clots, in conjunction with constipation.

Choice C rationale:

A platelet count of 45,000/mm^3 is low (thrombocytopenia), but it does not directly increase the risk of PE.

In fact, a low platelet count can sometimes hinder clot formation. However, it's important to monitor patients with thrombocytopenia for bleeding risks, as they may be more prone to bleeding complications.

Choice D rationale:

While receiving a transfusion of two units of packed red blood cells can increase blood viscosity, which could theoretically slightly increase the risk of PE, it is not a major risk factor.

Patients who receive transfusions are often already at an elevated risk of PE due to other underlying conditions or surgeries. It's essential to assess for other risk factors in these patients.

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.
