Question 1

A registered nurse is teaching nursing students about CD4 cells. Which statements made by a student nurse indicate effective teaching?

Accepted Answer

CD4 cells, also known as T-helper cells, are a type of T cell that plays a crucial role in the immune system by assisting other cells in mounting an immune response. They do not directly attack antigens or produce immunoglobulins; instead, they help activate other immune cells. The human immunodeficiency virus (HIV) specifically targets and destroys these cells, which is why option D is correct. Option E is also correct because it accurately describes the role of CD4 cells in cell-mediated immunity.

Question 2

A registered nurse is teaching a student nurse about the diagnosis of AIDS. Assess the statements made by the student nurse and identify the statements that indicate effective learning.

Accepted Answer

- A) The HIV RNA assay is indeed used to measure the viral load in clients with AIDS, which is an important aspect of monitoring the progression of the disease and the effectiveness of treatment.- E) The Western Blot test is used as a confirmatory test for HIV antibodies after an initial positive result from a screening test like ELISA, making it a critical step in the diagnosis of HIV.

Question 3

A registered nurse is teaching a student nurse about the diagnosis and treatment of hypogammaglobulinemia. Assess the statements made by the student nurse and identify the statements that indicate the need for further teaching.

Accepted Answer

Statement A is incorrect as hypogammaglobulinemia can be diagnosed at any age, not just at 1 year old. Statement E is incorrect as live vaccines should not be given to clients with hypogammaglobulinemia. The other statements (B, C, and D) are correct and do not require further teaching.

Question 4

Which is an autoimmune disease?

Accepted Answer

Rheumatoid arthritis is an autoimmune disease in which the body's immune system mistakenly attacks the joints, causing inflammation and damage. Osteoarthritis is a degenerative joint disease, and Type II diabetes is a metabolic disorder.

Question 5

A registered nurse is teaching a student nurse about interpreting blood test reports and urinalysis reports of clients with systemic lupus erythematosus (SLE). Which statements made by the student nurse indicate effective teaching?

Accepted Answer

B) Erythrocyte sedimentation rate (ESR) is a commonly used test for monitoring the degree of inflammation in clients with SLE. It is often high in clients with SLE due to the underlying chronic inflammation.
C) Leukopenia (low white blood cell count) and thrombocytopenia (low platelet count) are common hematological manifestations of SLE due to the autoimmune destruction of blood cells. These can be detected through blood testing. 
A) While a high ANA level is common in clients with SLE, it is not specific to SLE and can also be found in other autoimmune disorders and even in healthy individuals. 
D) C-reactive protein (CRP) is an acute phase protein that increases in response to inflammation. It is often elevated in acute SLE flares, not low. 
E) Urinalysis reports of clients with SLE may show proteinuria, hematuria, or signs of kidney inflammation, but not bacteriuria and pyuria which are indicative of a urinary tract infection.
