ATI Pathophysiology Exam 2 Questions
Question 1 of 5
If a patient complains of dizziness, which term below best describes this feeling?
Correct Answer: D
Rationale: The correct answer is D: 'Symptom.' Dizziness is a symptom because it is a subjective experience reported by the patient. A 'contraindication' refers to a specific situation in which a drug, procedure, or surgery should not be used because it may be harmful. A 'sign' is an objective finding that can be observed or measured. 'Objective data' refers to measurable and observable information about a patient's condition, which is usually obtained through physical examination or diagnostic tests. Therefore, in this case, 'Symptom' is the best term to describe the patient's feeling of dizziness.
Question 2 of 5
What is the primary role of albumin in the blood?
Correct Answer: C
Rationale: The correct answer is C: Maintain osmotic pressure and fluid balance. Albumin plays a crucial role in maintaining osmotic pressure by helping to retain fluid within the blood vessels. This function is essential for regulating blood volume and preventing fluid from leaking out into tissues. Choices A, B, and D are incorrect because albumin is not primarily responsible for transporting oxygen, acting as a clotting factor, or functioning as an immune response molecule in the blood.
Question 3 of 5
A patient has acute respiratory failure (ARF). Which of the following would the nurse expect to find?
Correct Answer: B
Rationale: In acute respiratory failure, hypoxemia (low blood oxygen) and hypercapnia (high blood carbon dioxide) are commonly observed. Choice A is incorrect because alkalosis (high pH) and hyperventilation are not typically seen in acute respiratory failure. Choice C is incorrect as it mentions alkalosis and high potassium, which are not characteristic of acute respiratory failure. Choice D is also incorrect because elevated sodium and acidosis are not typically associated with acute respiratory failure.
Question 4 of 5
A patient has a heart attack that leads to progressive cell injury resulting in cell death with severe cell swelling and breakdown of organelles. What term would the nurse use to define this process?
Correct Answer: D
Rationale: The correct answer is D: Necrosis. Necrosis is the process of cell death characterized by cell swelling, breakdown of organelles, and eventual rupture, often following ischemic injury like a heart attack. Choices A, B, and C are incorrect. Adaptation refers to the ability of cells to adjust to changes in their environment. Pathologic calcification is the abnormal deposition of calcium salts in tissues. Apoptosis is a programmed cell death that occurs in a controlled, orderly manner.
Question 5 of 5
What are the major mechanisms of spinal cord injuries?
Correct Answer: D
Rationale: The correct answer is D. Spinal cord injuries commonly occur due to hyperextension, hyperflexion, and compression. Hyperextension and hyperflexion refer to the excessive bending or stretching of the spinal cord, while compression is the exertion of pressure on the spinal cord. These mechanisms can lead to damage such as contusions, lacerations, and compression of the spinal cord. Choices A, B, and C are incorrect as they do not accurately represent the major mechanisms of spinal cord injuries.
