Introduction to Critical Care Nursing 8th Edition Questions
Question 1 of 5
A nurse is learning about the types of different cells involved in the inflammatory response. Which principles does the nurse learn? (Select the one that does not apply.)
Correct Answer: A
Rationale: The correct answer is A because basophils are not only involved in the general inflammatory process but are primarily associated with allergic reactions. Basophils release histamine and other chemicals that contribute to allergic responses. Choice B is incorrect because eosinophils do increase during allergic reactions and parasitic invasion. Choice C is correct as macrophages are known to participate in multiple episodes of phagocytosis, clearing pathogens and debris. Choice D is also correct as monocytes do differentiate into macrophages once they enter body tissues to perform their immune functions.
Question 2 of 5
A patient admitted to the coronary care unit (CCU) with an ST-segment-elevation myocardial infarction (STEMI) is restless and anxious. The blood pressure is 86/40 mm Hg, and heart rate is 132 beats/min. Based on this information, which patient problem is the priority?
Correct Answer: D
Rationale: The correct answer is D: Decreased cardiac output. In a patient with STEMI, a low blood pressure and high heart rate indicate decreased cardiac output, which is a life-threatening condition. Addressing this issue is crucial to prevent further complications like cardiogenic shock. Anxiety (A), acute pain (B), and stress management (C) are important but not immediate priorities in this scenario. Managing the patient's hemodynamic stability is paramount to ensure adequate tissue perfusion and prevent further deterioration.
Question 3 of 5
A patient is admitted to the hospital with possible acute pericarditis. What diagnostic test would the nurse expect the patient to undergo?
Correct Answer: B
Rationale: The correct answer is B: Echocardiography. This is because echocardiography is a non-invasive imaging test that can help visualize the pericardium and assess for signs of pericarditis. It can show if there is fluid around the heart or any inflammation. Blood cultures (A) are not typically used to diagnose pericarditis, as it is not an infectious process. Cardiac catheterization (C) is an invasive procedure used to evaluate coronary artery disease, not pericarditis. 24-hour Holter monitor (D) is used to monitor heart rhythms over a period of time and is not typically used in the initial diagnosis of acute pericarditis.
Question 4 of 5
A patient with acute shortness of breath is admitted to the hospital. Which action should the nurse take during the initial assessment of the patient?
Correct Answer: C
Rationale: The correct answer is C because during an acute episode of respiratory distress, it is essential to quickly gather specific information about the current situation. This allows the nurse to assess the severity of the issue, identify potential causes, and provide immediate interventions. Asking specific questions about the episode helps in determining the onset, triggers, associated symptoms, and any previous similar episodes. This information guides the nurse in prioritizing care and initiating appropriate interventions promptly. Choice A is incorrect because asking the patient to lie down for a full physical assessment is not appropriate during acute respiratory distress as it delays crucial information gathering. Choice B is incorrect as completing the health history and checking for allergies can be done after addressing the immediate respiratory distress. Choice D is incorrect because delaying the physical assessment for pulmonary function tests is not indicated in the acute management of respiratory distress.
