Questions About the Immune System Questions
Question 1 of 5
Systemic lupus erythematosus (SLE)- nurse plan to include in teaching?
Correct Answer: B
Rationale: Step 1: Monitoring body temperature is crucial in SLE patients as fever can indicate disease exacerbation or infection. Step 2: Prompt reporting of any elevations allows for timely intervention and prevents complications. Step 3: Early detection and management of fever can improve outcomes and quality of life for patients. Summary: Choices A, C, and D are incorrect as they do not address the key concerns of monitoring for disease exacerbation or infection in SLE patients.
Question 2 of 5
What is a component of the immune system? Select one that does not apply
Correct Answer: B
Rationale: The correct answer is B: blood vessels. In the immune system, cells, tissues, and organs play crucial roles in defending the body against pathogens. Blood vessels, while important for transporting immune cells and substances, are not considered a direct component of the immune system itself. They serve as conduits for immune cells to travel throughout the body but do not actively participate in immune responses like cells, tissues, and organs do. Blood vessels are essential for the immune system to function effectively, but they are not considered a direct component of the immune system. Therefore, B is the correct answer.
Question 3 of 5
A ferritin level test assesses:
Correct Answer: B
Rationale: The correct answer is B: A ferritin level test assesses how much iron may be stored in the body. Ferritin is a protein that stores iron, so measuring ferritin levels gives an indication of the body's iron stores. Haemoglobin levels are not directly measured by ferritin tests (A). Ferritin levels do not assess the blood's clotting ability (C) or the number of white blood cells (D). These are unrelated to iron storage.
Question 4 of 5
The term petechiae refers to:
Correct Answer: C
Rationale: The term petechiae refers to small red or purple spots on the skin caused by broken blood vessels. These spots are typically pinpoint in size and do not raise above the skin surface. The correct answer is C, as it accurately describes the characteristic appearance of petechiae. Option A is incorrect as petechiae are not large or raised. Option B is incorrect as petechiae are not indicative of an infection. Option D is incorrect as petechiae are not related to deep vein thrombosis.
Question 5 of 5
People with irritable bowel syndrome often suffer with:
Correct Answer: C
Rationale: The correct answer is C: Diarrhoea and constipation. Individuals with irritable bowel syndrome (IBS) can experience alternating episodes of diarrhoea and constipation. This is due to the dysfunction in the gut-brain axis, leading to abnormal contractions in the intestines. Symptoms vary among individuals and can include bloating, abdominal pain, and changes in bowel habits. Diarrhoea and constipation are common manifestations of IBS, affecting different individuals at different times. This makes option C the correct choice. Option A (Diarrhoea) and Option D (Constipation) are incorrect because IBS is characterized by both diarrhoea and constipation, not just one or the other. Option B (Urinary tract infections) is unrelated to IBS symptoms and is not a common manifestation of the condition.
