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 C

Explanation

Choice A rationale:

Buffers do not excrete weak acids; instead, they help regulate the pH of bodily fluids by preventing drastic changes in acidity or alkalinity.

Choice B rationale:

Buffers do not secrete hydrogen ions. In fact, buffers can either absorb or release hydrogen ions to maintain a stable pH.

Choice C rationale:

To convert strong acids to weak acids is the correct answer. Buffers are substances that can neutralize both acids and bases, helping to maintain a stable pH in a solution. They achieve this by accepting hydrogen ions from strong acids or donating hydrogen ions to strong bases, converting them into weaker acids or bases, respectively.

Choice D rationale:

Buffers do not convert ammonia to ammonium ions. This conversion is a part of the body's acid-base regulation system, but it is not the primary function of buffers.

A. Mexican Americans have higher rates of good blood pressure control. B. Mexican Americans are more likely to receive treatment for hypertension. C. Mexican Americans have the highest prevalence of hypertension in the world. D. Mexican Americans have lower levels of awareness of hypertension and its treatment.

Correct Answer is D

Explanation

Choice A rationale:

This statement is incorrect. Mexican Americans do not have higher rates of good blood pressure control compared to other populations.

Choice B rationale:

This statement is incorrect. Mexican Americans are not more likely to receive treatment for hypertension compared to other populations.

Choice C rationale:

This statement is incorrect. While hypertension is prevalent among Mexican Americans, stating they have the highest prevalence of hypertension in the world is inaccurate. The prevalence of hypertension is influenced by various factors and can vary across different regions globally.
