Nursing Elites

1. A hemoglobin electrophoresis is done to evaluate for sickle cell disease. The report reveals the person has HbAS, which means the person:

• A. is normal with no sickle cell disease.
• B. is a sickle cell carrier.
• C. has sickle cell anemia.
• D. has thalassemia.

Correct answer: B

Rationale: HbAS indicates sickle cell trait, not full-blown sickle cell anemia. Choice A is incorrect because HbAS indicates the presence of the sickle cell trait. Choice C is incorrect as sickle cell anemia is characterized by HbSS, not HbAS. Choice D is incorrect as thalassemia is a different type of hemoglobin disorder not indicated by HbAS.

2. A patient is receiving intravenous amphotericin. Which of the following assessments warrants the discontinuation of the antifungal agent?

• A. Sodium level of 138 mEq/L
• B. Hematocrit of 39%
• C. Blood urea nitrogen of 60 mg/dL
• D. AST level of 10 Unit/L

Correct answer: C

Rationale: Intravenous amphotericin can cause nephrotoxicity, leading to increased blood urea nitrogen levels. Elevated blood urea nitrogen (BUN) indicates impaired renal function, which is a known adverse effect of amphotericin. Therefore, a BUN level of 60 mg/dL warrants the discontinuation of the antifungal agent. The other options, such as a sodium level of 138 mEq/L, hematocrit of 39%, and AST level of 10 Unit/L, are within normal ranges and not indicative of the need to discontinue amphotericin therapy.

3. 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.

4. Which goal is a priority for a client with a DSM-IV-TR diagnosis of delirium and the nursing diagnosis Acute confusion related to recent surgery secondary to traumatic hip fracture?

• A. The client will complete activities of daily living.
• B. The client will maintain safety.
• C. The client will remain oriented.
• D. The client will understand communication.

Correct answer: B

Rationale: The correct answer is B: 'The client will maintain safety.' For a client with delirium, especially in the context of acute confusion post-surgery, safety is the top priority. Delirium can lead to disorientation, impaired decision-making, and increased risk of falls or accidents. Ensuring the client's safety by implementing measures to prevent harm is crucial. Choices A, C, and D are important but not the priority in this scenario. Completing activities of daily living, remaining oriented, and understanding communication are relevant goals but come after ensuring the client's safety in the presence of delirium and acute confusion.

5. When the maternal immune system becomes sensitized against antigens expressed by the fetus, what type of immune reaction occurs?

• A. Autoimmune
• B. Anaphylaxis
• C. Alloimmune
• D. Allergic

Correct answer: C

Rationale: When the maternal immune system becomes sensitized against antigens expressed by the fetus, an alloimmune reaction occurs. In this situation, the mother's immune system recognizes the fetus as foreign due to differences in antigens, leading to an immune response against the fetus. Choice A, 'Autoimmune,' is incorrect because it refers to the immune system mistakenly attacking the body's own cells and tissues. Choice B, 'Anaphylaxis,' is not the correct answer as it is a severe allergic reaction that can be life-threatening. Choice D, 'Allergic,' is also incorrect as it refers to an immune response triggered by allergens, not antigens expressed by the fetus.
