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: The correct answer is that the person is a sickle cell carrier. In HbAS, 'Hb' stands for hemoglobin, 'A' indicates normal hemoglobin, and 'S' indicates the sickle cell trait. Individuals with HbAS are carriers of the sickle cell trait but do not have sickle cell disease. Choice A is incorrect because having the sickle cell trait means carrying the gene for sickle cell disease. Choice C is incorrect as sickle cell anemia is a different condition where individuals have two copies of the abnormal hemoglobin gene, resulting in the disease. Choice D is incorrect because thalassemia is a separate genetic disorder affecting the production of hemoglobin, not related to the sickle cell trait.

2. After a patient is exposed to a specific antigen, B cells will differentiate into:

• A. B cytotoxic cells
• B. Plasma cells
• C. Bursal cells
• D. Clonal equivalents

Correct answer: B

Rationale: After exposure to a specific antigen, B cells undergo differentiation into plasma cells. Plasma cells are responsible for producing antibodies in response to the antigen. Choice A ('B cytotoxic cells') is incorrect because B cells do not differentiate into cytotoxic cells; cytotoxic cells are typically associated with T cells. Choice C ('Bursal cells') is incorrect as bursal cells are specific to birds and not relevant to human immune responses. Choice D ('Clonal equivalents') is incorrect as it does not describe the differentiation process of B cells exposed to antigens.

3. A client presents to the emergency department with complaints of chest pain and shortness of breath. The client's ECG shows ST-segment elevation. What is the priority nursing intervention?

• A. Administer aspirin as prescribed.
• B. Prepare the client for emergent coronary angiography.
• C. Administer oxygen therapy.
• D. Initiate CPR.

Correct answer: B

Rationale: In a client presenting with chest pain, shortness of breath, and ST-segment elevation on ECG, the priority nursing intervention is to prepare the client for emergent coronary angiography. This procedure is crucial in diagnosing and treating acute myocardial infarction promptly. Administering aspirin (Choice A) is important but not the priority over emergent coronary angiography. Administering oxygen therapy (Choice C) is supportive but does not address the underlying cause of the ST-segment elevation. Initiating CPR (Choice D) is not the priority in this scenario as the client is stable and conscious.

4. Cushing syndrome is characterized by which disorder?

• A. Hypocortisolism
• B. Exophthalmos
• C. Hypercortisolism
• D. Hyperpigmentation

Correct answer: C

Rationale: Cushing syndrome is characterized by hypercortisolism, which is an excessive amount of cortisol in the body. Choice A, 'Hypocortisolism,' is incorrect as Cushing syndrome is associated with elevated cortisol levels. Choice B, 'Exophthalmos,' refers to bulging eyes and is not a characteristic feature of Cushing syndrome. Hyperpigmentation, as mentioned in choice D, can be present in Cushing syndrome due to increased ACTH levels stimulating melanocytes, but it is not the defining characteristic of the syndrome.

5. A female patient is prescribed medroxyprogesterone acetate (Provera) for dysfunctional uterine bleeding. What should the nurse include in the patient education?

• A. This medication may cause breakthrough bleeding or spotting.
• B. This medication may cause weight gain.
• C. This medication may increase your risk of developing diabetes.
• D. This medication may increase your risk of breast cancer.

Correct answer: A

Rationale: The correct answer is A. Medroxyprogesterone acetate (Provera) can cause breakthrough bleeding or spotting, which is a common side effect of this medication. Choices B, C, and D are incorrect because weight gain, increased risk of diabetes, and increased risk of breast cancer are not commonly associated side effects of medroxyprogesterone acetate. Therefore, the nurse should focus on educating the patient about the potential for breakthrough bleeding or spotting.
