ATI Pathophysiology Exam 3 Questions
Question 1 of 5
Which of the following describes passive immunity?
Correct Answer: B
Rationale: Passive immunity is the transfer of pre-formed antibodies from one individual to another, providing immediate but temporary protection. In this case, the correct answer is the transfer of antibodies from the mother to the baby, as it describes the concept of passive immunity. Choice A, vaccination against the disease, refers to active immunity where the individual's immune system is stimulated to produce antibodies. Choice C, cuts or wounds that are infected and heal, is unrelated to immunity. Choice D, having the disease in question, does not describe passive immunity but rather acquiring active immunity through exposure to the pathogen.
Question 2 of 5
What lab results would be noted in a client with leukocytosis?
Correct Answer: A
Rationale: Leukocytosis is a condition characterized by an elevated white blood cell count, typically in response to infection or inflammation. Therefore, the correct answer is an increased white blood cell count (Choice A). Increased platelet count (Choice B) is not a typical finding in leukocytosis. Choices C and D, decreased white blood cell count and decreased platelet count respectively, are opposite to what would be expected in leukocytosis and are therefore incorrect.
Question 3 of 5
What occurs in a client with polycythemia?
Correct Answer: C
Rationale: The correct answer is C: Increased red blood cells being produced. Polycythemia is a condition characterized by an elevated number of red blood cells in the blood. This increased concentration of red blood cells can lead to blood thickening and potentially result in complications such as blood clots. Choices A, B, and D are incorrect because polycythemia does not involve deficient plasma, increased lymphatic fluid production, or a deficient number of red blood cells.
Question 4 of 5
Which of the following are signs and symptoms of myocardial infarction?
Correct Answer: A
Rationale: The correct answer is A. Persistent chest pain that may radiate to the arm is a classic symptom of myocardial infarction. This pain is typically described as crushing, pressure-like, or squeezing. Choice B is incorrect because brief sternal chest pain on inspiration is not characteristic of myocardial infarction. Choice C is incorrect because rapid respirations with left-sided weakness and numbness are not typical symptoms of myocardial infarction. Choice D is incorrect because left upper quadrant abdominal pain that radiates to the back and shoulder is not a common presentation of myocardial infarction.
Question 5 of 5
Which of the following is a cause of edema?
Correct Answer: A
Rationale: The correct answer is A: Decreased plasma proteins. Edema can be caused by decreased plasma proteins, which reduce the osmotic pressure that keeps fluid in the blood vessels. Hypotension (choice B) is low blood pressure and is not a direct cause of edema. Dehydration (choice C) involves a lack of body fluid, but it is not a direct cause of edema. Polyuria (choice D) is excessive urination and not a direct cause of edema.
