Question 1 of 5
Which of the ff is an initial sign or symptom of acute bronchitis?
Correct Answer: A
Rationale: An initial sign or symptom of acute bronchitis is a nonproductive cough. This type of cough produces little to no phlegm or sputum. As the condition progresses, the cough may become productive, with the production of thick yellow or green mucus. Other common symptoms of acute bronchitis may include chest discomfort, fatigue, mild fever, and sore throat. Labored breathing is more commonly associated with conditions such as pneumonia or asthma, while anorexia and gastric ulceration are not typically initial signs of acute bronchitis.
Question 2 of 5
The activation of B cells in humoral immunity is assisted by which of the following?
Correct Answer: C
Rationale: In humoral immunity, the activation of B cells is facilitated by helper T cells. Helper T cells play a crucial role in coordinating the immune response by interacting with B cells. They secrete cytokines that stimulate B cells to proliferate and differentiate into antibody-secreting plasma cells. Without the assistance of helper T cells, the activation of B cells and the production of antibodies would be impaired. Cytotoxic T cells are involved in cell-mediated immunity, supressor T cells regulate immune response, and neutrophils are involved in phagocytosis and innate immunity, but they do not directly assist in B cell activation in humoral immunity.
Question 3 of 5
The nurse understands that an anaphylactic reaction is considered which of the following types of hypersensitivity reactions?
Correct Answer: A
Rationale: An anaphylactic reaction is considered a Type I hypersensitivity reaction. In Type I hypersensitivity, the immune system produces IgE antibodies in response to an allergen, leading to the release of various inflammatory mediators like histamine. This immediate systemic reaction can cause symptoms such as hives, itching, swelling, difficulty breathing, and in severe cases, anaphylactic shock. These reactions occur quickly, typically within minutes to hours after exposure to the allergen. Anaphylaxis is a medical emergency that warrants immediate intervention with epinephrine and supportive care.
Question 4 of 5
A patient who is being tested for HIV asks what tests are used. The nurse would correct in stating that the tests used to confirm HIV infection are which of the following?
Correct Answer: B
Rationale: ELISA (Enzyme-Linked Immunosorbent Assay) and Western Blot are the two main tests used to confirm HIV infection. ELISA is typically the first test performed to detect HIV antibodies in the blood. If the ELISA test is positive, the Western Blot test is then used to confirm the presence of HIV antibodies and differentiate between HIV-1 and HIV-2 antibodies. Both tests are highly sensitive and specific in diagnosing HIV infection. Other tests like CD4+ count and viral load are used to monitor disease progression but are not used primarily to confirm HIV infection.
Question 5 of 5
The nurse encourages a client with an immunologic disorder to eat a nutritionally balanced diet to promote optimal immunologic function. Autoimmunity has been linked to excessive ingestion of:
Correct Answer: C
Rationale: Excessive ingestion of fat has been linked to autoimmunity. A diet high in saturated and trans fats can lead to chronic inflammation and disrupt the balance of immune cells, potentially triggering autoimmune responses in the body. Conversely, a nutritionally balanced diet that includes healthy fats like omega-3 fatty acids from sources such as fish, nuts, and seeds can help support optimal immunologic function and reduce the risk of autoimmune disorders.
