Hematologic System Assessment Questions Questions
Question 1 of 5
Which of the following best describes the movement of a T cell through a lymph node?
Correct Answer: D
Rationale: The correct answer is D because T cells enter the lymph node via the bloodstream through high endothelial venules and exit via efferent lymphatics. This process allows them to circulate between lymph nodes and peripheral tissues to survey for pathogens. Option A is incorrect because efferent lymphatics carry lymph away from the lymph node. Option B is incorrect as T cells enter via the bloodstream, not afferent lymphatics. Option C is incorrect as T cells exit via efferent lymphatics, not afferent lymphatics.
Question 2 of 5
Which statement made by the nurse indicates an understanding of the clinical manifestations of anemia from acute blood loss?
Correct Answer: B
Rationale: The correct answer is B because feeling lightheaded and experiencing a drop in blood pressure upon standing are common clinical manifestations of anemia from acute blood loss. This indicates that the body is not able to adequately supply oxygen to tissues due to decreased red blood cell count. Option A is incorrect as focusing solely on high iron diet overlooks the immediate need for medical intervention. Options C and D are incomplete, thus cannot be evaluated.
Question 3 of 5
A nurse is assessing a client who has pericarditis. Which of the following manifestations should the nurse expect?
Correct Answer: A
Rationale: The correct answer is A: Dyspnea with hiccups. Pericarditis is inflammation of the pericardium, leading to chest pain worsened by lying flat and relieved by sitting upright. Dyspnea (shortness of breath) may occur due to compression of the heart by fluid or inflammation. Hiccups can result from irritation of the diaphragm. Fever with chills (choice C) is more indicative of an infectious process. Tachycardia alone (choice D) is a nonspecific symptom and can occur in various conditions, but pericarditis typically presents with a combination of symptoms including chest pain and dyspnea.
Question 4 of 5
A nurse is planning care for a client who is having a percutaneous transluminal coronary angioplasty (PTCA) with stent placement. Which of the following actions should the nurse anticipate in the post-procedure plan of care?
Correct Answer: A
Rationale: The correct answer is A: Monitor for bleeding. After PTCA with stent placement, the nurse should anticipate monitoring the client for signs of bleeding at the catheter insertion site. This is crucial as bleeding is a common complication post-procedure. The nurse should assess the insertion site regularly for any signs of bleeding, such as swelling, hematoma, or active bleeding. Prompt identification and management of bleeding can prevent further complications. Summary of why other choices are incorrect: B: Administer beta blockers - Beta blockers are not typically administered immediately post-PTCA with stent placement. They may be part of the long-term management for cardiac conditions but are not a priority post-procedure. C: Increase fluid intake - While maintaining adequate hydration is important for overall health, increasing fluid intake is not a specific post-procedure intervention for PTCA with stent placement. D: Restrict all movement - Restricting all movement post-PTCA with stent placement is not necessary. Encouraging
Question 5 of 5
A nurse is assessing for cardiac tamponade on a client who had coronary artery bypass grafts. Which of the following actions should the nurse take?
Correct Answer: A
Rationale: The correct answer is A: Auscultate blood pressure for pulsus paradoxus. This is the most appropriate action because pulsus paradoxus is a key sign of cardiac tamponade, where there is an abnormal drop in blood pressure during inspiration. This occurs due to increased pressure on the heart caused by fluid accumulation in the pericardial sac. Checking for chest pain (B) may not be specific to cardiac tamponade. Monitoring ECG for ST changes (C) is important but may not be as immediate as assessing for pulsus paradoxus. Assessing respiratory rate (D) is also important but may not be as specific to cardiac tamponade as checking for pulsus paradoxus.
