Which white blood cells are involved in releasing histamine during an allergic reaction?
- A. Basophils
- B. Monocytes
- C. Eosinophils
- D. Neutrophils
Correct Answer: A
Rationale: Basophils are a type of white blood cell that are involved in releasing histamine during an allergic reaction. When an allergen triggers the immune system, basophils release histamine and other chemical mediators. Histamine plays a key role in the inflammatory response associated with allergies, leading to symptoms such as itching, hives, and swelling. Basophils are known for their role in allergic reactions and are an important part of the body's defense against parasites and in the inflammatory response.

Correct Answer: B
Rationale: For a client with polycythemia vera, there is an increased risk for thrombus formation due to the increased viscosity of the blood. Wearing thromboembolic stockings or support hose can help promote circulation, prevent stasis, and reduce the risk of thrombus formation. Compression stockings provide external pressure to the legs, which helps prevent blood from pooling and clotting. This intervention is commonly recommended for patients at risk for thrombus formation to improve blood flow in the lower extremities and reduce the risk of deep vein thrombosis (DVT) and pulmonary embolism.

Which of the ff factors predisposes a client to the development of TB?
- A. Exposure to toxic gases
- B. Congenital abnormalities
- C. Obstruction by tumor
- D. Malnutrition
Correct Answer: D
Rationale: Malnutrition predisposes a client to the development of Tuberculosis (TB) because a lack of proper nutrition weakens the immune system, making the individual more susceptible to infections such as TB. Adequate nutrition is essential for maintaining a healthy immune system that can effectively fight off pathogens. Malnourished individuals are less able to mount a strong immune response, thus increasing their vulnerability to contracting TB and experiencing more severe symptoms and complications from the disease.
