Nursing Elites

1. How should the nurse prepare a patient who is to receive a Schilling test for pernicious anemia?

• A. Administer radioactive cobalamin and measure its excretion time
• B. Measure antigen-antibody immune complexes
• C. Measure serum ferritin and total iron-binding capacity
• D. Administer folate and evaluate folate content in a blood serum sample

Correct answer: A

Rationale: The correct answer is A. To prepare a patient for a Schilling test for pernicious anemia, the nurse should administer radioactive cobalamin and measure its excretion time. This test is specifically designed to assess the absorption of vitamin B12. Choices B, C, and D are incorrect because they do not align with the preparation and procedure of a Schilling test. Measuring antigen-antibody immune complexes, serum ferritin, or total iron-binding capacity, as well as administering folate and evaluating folate content, are not part of the Schilling test protocol.

2. A patient is prescribed testosterone gel for hypogonadism. What important instruction should the nurse provide regarding the application of this medication?

• A. Apply the gel to the chest or upper arms.
• B. Apply the gel to the face and neck.
• C. Apply the gel to the genitals for maximum absorption.
• D. Apply the gel to the scalp and back.

Correct answer: A

Rationale: The correct answer is to apply the testosterone gel to the chest or upper arms. This is recommended to minimize the risk of unintentional transfer of the medication to others, especially women and children, through skin contact. Applying the gel to the face, neck, or genitals is not advised as it can lead to unintended exposure to others. Additionally, applying the gel to the scalp or back is not appropriate as these areas are not indicated for absorption of testosterone.

3. A 35-year-old male has enlarged lymph nodes in the neck and a mediastinal mass. He was diagnosed with Hodgkin lymphoma. Which of the following abnormal cells would the nurse expect to find with this disease?

• A. Merkel cell
• B. Schwann cell
• C. Reed-Sternberg cell
• D. Kupffer cell

Correct answer: C

Rationale: Reed-Sternberg cells are characteristic of Hodgkin lymphoma. These large abnormal cells have a bi-lobed or multi-lobed nucleus and are essential for diagnosing Hodgkin lymphoma through histological examination. Merkel cells are associated with Merkel cell carcinoma, Schwann cells are related to nerve sheaths, and Kupffer cells are liver macrophages. Therefore, choices A, B, and D are incorrect for Hodgkin lymphoma.

4. DiGeorge syndrome is a primary immune deficiency caused by:

• A. Failure of B cells to mature
• B. Congenital lack of thymic tissue
• C. Failure of formed elements of blood to develop
• D. Selective IgG deficiency

Correct answer: B

Rationale: DiGeorge syndrome is caused by a congenital lack of thymic tissue, which plays a crucial role in T cell development and maturation, leading to immune deficiency. Choice A is incorrect because DiGeorge syndrome primarily affects T cells, not B cells. Choice C is incorrect as it is too broad and not specific to the thymus. Choice D is incorrect as selective IgG deficiency is a different condition unrelated to DiGeorge syndrome.

5. The canola plant's genome is altered to produce an herbicide-resistant crop. The canola oil produced from this crop is an example of a:

• A. pesticide-free food.
• B. saturated fat food.
• C. genetically modified food.
• D. product that is pure.

Correct answer: C

Rationale: The correct answer is C: genetically modified food. Canola plants with altered genomes to be herbicide-resistant are an example of genetically modified organisms (GMOs). Genetically modified foods have their genetic material modified for various purposes, such as enhancing resistance to pests, herbicides, or improving nutritional content. Choice A, 'pesticide-free food,' is incorrect because genetic modification does not necessarily make the food pesticide-free. Choice B, 'saturated fat food,' is incorrect as it does not relate to the genetic modification of the canola plant. Choice D, 'product that is pure,' is too vague and does not specifically address the genetic modification aspect of the canola plant.
