Nursing Elites

1. If a patient complains of dizziness, which term below best describes this feeling?

• A. Contraindication
• B. Sign
• C. Objective data
• D. Symptom

Correct answer: D

Rationale: The correct answer is D: 'Symptom.' Dizziness is a symptom because it is a subjective experience reported by the patient. A 'contraindication' refers to a specific situation in which a drug, procedure, or surgery should not be used because it may be harmful. A 'sign' is an objective finding that can be observed or measured. 'Objective data' refers to measurable and observable information about a patient's condition, which is usually obtained through physical examination or diagnostic tests. Therefore, in this case, 'Symptom' is the best term to describe the patient's feeling of dizziness.

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 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.

4. The registered nurse is teaching a class on inflammation and explains that which cell is the predominant phagocyte arriving early at inflammatory and infection sites?

• A. Macrophages
• B. Mast cells
• C. Monocytes
• D. Neutrophils

Correct answer: D

Rationale: Neutrophils are the correct answer as they are the predominant phagocytes arriving early at inflammatory and infection sites. Neutrophils are part of the body's innate immune system and are among the first responders to sites of inflammation or infection. They play a crucial role in engulfing and destroying pathogens. Macrophages, although important phagocytes, usually arrive later at the site. Mast cells are involved in allergic reactions and not primarily phagocytes. Monocytes are precursors to macrophages and are not the predominant phagocytes arriving early at inflammatory sites.

5. A patient is prescribed estradiol (Estrace) for hormone replacement therapy. What should the nurse monitor during this therapy?

• A. Blood pressure
• B. Blood glucose levels
• C. Liver function tests
• D. Kidney function tests

Correct answer: C

Rationale: During estradiol therapy, the nurse should monitor liver function tests. Estradiol can potentially impact liver function, making it essential to assess for any signs of liver dysfunction. Monitoring blood pressure (Choice A) is not directly related to estradiol therapy. While blood glucose levels (Choice B) should be monitored in patients taking certain medications like corticosteroids or antipsychotics, it is not typically necessary for patients on estradiol therapy. Kidney function tests (Choice D) are not the priority for monitoring during estradiol therapy, as the liver is more commonly affected.
