Multiple Choice Questions on Immune System Questions
Question 1 of 5
The primary nursing intervention to prevent bacterial endocarditis is which of the following?
Correct Answer: A
Rationale: The correct answer is A because counseling parents of high-risk children about the importance of prophylactic antibiotics before dental procedures is the primary nursing intervention to prevent bacterial endocarditis. This is crucial as dental procedures can introduce bacteria into the bloodstream, leading to endocarditis in susceptible individuals. Choice B is incorrect because preventing dental procedures altogether is not necessary, rather ensuring prophylactic antibiotics are administered before procedures is key. Choice C, encouraging restricted mobility, is not a recommended intervention for preventing endocarditis. Choice D focuses on observing for complications rather than preventing the condition in the first place, making it an incorrect choice.
Question 2 of 5
Which of the following statements is false?
Correct Answer: B
Rationale: The correct answer is B because hematopoietic stem cells give rise to all blood cell types, including both white and red blood cells. The other choices are true: A is correct as hematopoiesis does occur in various locations, C is true as hematopoietic stem cells can self-renew, and D is accurate as platelets do participate in clotting to prevent blood loss. Overall, B is the only statement that is false in this context.
Question 3 of 5
The nurse is caring for someone with a low red blood cell (erythrocyte) count. The nurse explains the function of the erythrocyte is to (select ONE that apply.)
Correct Answer: B
Rationale: Step 1: Erythrocytes carry oxygen bound to hemoglobin. This is correct as they transport oxygen from the lungs to the body tissues. Step 2: Erythrocytes also carry some carbon dioxide. This is the correct answer because they pick up carbon dioxide from the tissues and transport it to the lungs for exhalation. Step 3: Erythrocytes do not assist with clotting, which is primarily the role of platelets and certain proteins in the blood. Step 4: Erythrocytes do not assist with immunity, as that function is mainly carried out by white blood cells.
Question 4 of 5
Which nutrient is necessary for erythropoiesis? Select one that does not apply.
Correct Answer: B
Rationale: The correct answer is B: Vitamin C. Vitamin C is not necessary for erythropoiesis, the process of red blood cell production. Iron is essential for hemoglobin synthesis, Vitamin B12 is needed for DNA synthesis in red blood cells, and Folic acid is crucial for cell division and growth in erythropoiesis. Vitamin C plays a role in collagen production and immune function, but it is not directly involved in red blood cell formation.
Question 5 of 5
Which nursing care should be prioritized when caring for a patient recovering from a bone marrow biopsy? Select one that does not apply.
Correct Answer: C
Rationale: The correct answer is C: Administer sedatives. Administering sedatives is not a priority when caring for a patient recovering from a bone marrow biopsy because sedatives are not typically needed for this procedure. The priority nursing care should focus on assessing for excess bleeding (A), providing analgesics for pain relief (B), and monitoring vital signs (D) to ensure the patient's safety and recovery. Sedatives may not be necessary and could potentially mask important signs or symptoms that need immediate attention. Prioritizing the assessment for bleeding, pain management, and monitoring vital signs ensures the patient's well-being and identifies any complications early on.
