Questions on the Immune System Questions
Question 1 of 5
What is a consideration for patients taking colchicine?
Correct Answer: A
Rationale: The correct answer is A because colchicine commonly causes gastrointestinal (GI) upset as a side effect. This is due to its mechanism of action on the gastrointestinal tract. Retinal damage (B), bone marrow suppression (C), and hepatotoxicity (D) are not commonly associated with colchicine use, making them incorrect choices. It's crucial to monitor patients for GI symptoms when taking colchicine to ensure their safety and manage any adverse effects promptly.
Question 2 of 5
The nurse is assessing a client for signs and symptoms of systemic lupus erythematosus (SLE). Which of the following would be consistent with this disorder? (Select one that does not apply.)
Correct Answer: C
Rationale: The correct answer is C: Painful, deformed small joints. This is consistent with systemic lupus erythematosus (SLE) as it can cause joint pain and inflammation, leading to joint deformities. A: Discoid rash on skin exposed to sunlight is a characteristic of cutaneous lupus, not systemic lupus. B: Urinalysis positive for casts and protein is more indicative of lupus nephritis, a complication of SLE affecting the kidneys. D: Pain on inspiration is more suggestive of pleurisy, a common symptom in SLE but not specific to the disease.
Question 3 of 5
A patient with thalassemia has been found to have high iron levels. Which of the following agents would be appropriate for management of this patient?
Correct Answer: C
Rationale: The correct answer is C: Deferoxamine. Thalassemia patients often require blood transfusions, leading to iron overload. Deferoxamine is an iron-chelating agent that helps remove excess iron from the body. Ferrous sulphate (A) is an iron supplement and would worsen iron overload. Hydroxycobalamin (B) is a form of vitamin B12 and is not indicated for iron overload. Iron dextran (D) is another form of iron supplement and would also exacerbate the iron overload in this patient. Therefore, the appropriate choice is C as it directly addresses the issue of high iron levels in thalassemia patients.
Question 4 of 5
During a secondary humoral response:
Correct Answer: D
Rationale: During a secondary humoral response, memory B cells are activated, leading to a faster and more robust production of Ig antibodies than in the primary response. IgG antibodies, in particular, are produced in higher amounts and persist longer than IgM antibodies. This is because memory B cells are already primed to quickly differentiate into plasma cells upon re-exposure to the same antigen, resulting in a more rapid and efficient immune response. Therefore, choice D is correct. Choices A, B, and C are incorrect because they do not accurately reflect the characteristics of a secondary humoral response.
Question 5 of 5
A client arrives at the health care clinic and tells the nurse that she was just bitten by a tick and would like to be tested for Lyme disease. The client tells the nurse that she removed the tick and flushed it down the toilet. Which actions are most appropriate?
Correct Answer: B
Rationale: The correct answer is B: Inform the client to plan to have a blood test 4 to 6 weeks after a bite to detect the presence of the disease. Rationale: 1. Lyme disease testing is most accurate 4-6 weeks post-bite due to the time required for antibodies to develop. 2. Testing too early may result in false negatives. 3. Waiting allows for accurate detection and timely treatment if needed. Summary of Other Choices: A: Incorrect. Arthralgia is just one symptom; testing is needed for accurate diagnosis. C: Incorrect. While prevention is important, this does not address the immediate need for testing. D: Incorrect. Antibiotics should not be started without proper diagnosis to avoid unnecessary medication.
