Which laboratory report finding would support the nurse's conclusion that a patient has thalassemia major? Select all that apply.
One, some, or all responses may be correct.

Increased bilirubin levels.

Increased reticulocyte level.

Increased mean corpuscular volume.

Increased total iron-binding capacity.

Answer and Explanation

Correct Answer : A,B,D

Choice A rationale:

Increased bilirubin levels can occur in thalassemia major due to the destruction of red blood cells, leading to elevated bilirubin, which is a breakdown product of hemoglobin. This elevation can contribute to jaundice and other symptoms.

Choice B rationale:

Thalassemia major leads to the destruction of red blood cells, causing the bone marrow to release more reticulocytes (immature red blood cells) into the bloodstream. Therefore, an increased reticulocyte level is expected in thalassemia major.

Choice C rationale:

Increased mean corpuscular volume (MCV) is not a typical finding in thalassemia major. Thalassemia major is characterized by microcytic (smaller than normal) red blood cells, leading to a decreased MCV.

Choice D rationale:

Thalassemia major causes increased iron absorption by the intestines, leading to elevated total iron-binding capacity (TIBC) TIBC measures the body's capacity to bind and transport iron in the blood, and elevated levels are seen in conditions with increased iron demand, such as thalassemia major.

Correct Answer is D

Explanation

Choice A rationale:

Adequate platelet production does not explain the prolonged bleeding times in von Willebrand disease. These patients often have normal platelet counts, but their platelets do not function properly due to the absence or dysfunction of von Willebrand factor.

Choice B rationale:

Deficiency in intrinsic clotting system factor is not the primary cause of prolonged bleeding times in von Willebrand disease. The deficiency or dysfunction of von Willebrand factor, a protein that helps platelets adhere to the blood vessel walls and clot properly, is the key issue in this disorder.

Choice C rationale:

Impairment of the thrombin fibrinogen reaction does not directly relate to von Willebrand disease. This disorder primarily involves platelet dysfunction and variable factor VIII deficiencies, leading to prolonged bleeding times.

Choice D rationale:

Variable factor VIII deficiencies and platelet dysfunction are characteristic of von Willebrand disease. Factor VIII helps with blood clotting, and its deficiency, along with impaired platelet function, contributes to the prolonged bleeding times in patients with von Willebrand disease.

A. Restricting all visitors. B. Placing the patient in a private room. C. Advising the patient to use only an electric shaver. D. Wearing a gown and gloves when in direct contact with the patient.

Correct Answer is B

Explanation

Choice A rationale:

Restricting all visitors might be beneficial in preventing infections, but it is not the most important strategy for a patient with neutropenia. The main concern is the risk of infections due to the compromised immune system.

Choice B rationale:

Placing the patient in a private room is crucial for a neutropenic patient. Neutropenia, characterized by a low absolute neutrophil count (ANC), significantly compromises the patient's immune system, making them highly susceptible to infections. Isolating the patient helps minimize the risk of exposure to pathogens, reducing the likelihood of infections.

Choice C rationale:

Using an electric shaver instead of a razor is advisable to prevent cuts and minimize the risk of skin infections. While this is a good practice, it is not the most important strategy compared to isolating the patient and using personal protective equipment (PPE) during direct patient care.

Choice D rationale:

Wearing a gown and gloves when in direct contact with the patient is essential to prevent the spread of infections. This is a necessary measure, but isolating the patient in a private room takes precedence as it minimizes the risk of exposure to pathogens, providing a safer environment for the neutropenic patient.
