ATI Pathophysiology Exam 3
1. When arterial blood pressure declines, the kidneys secrete a hormone to increase blood pressure and peripheral resistance. What is this hormone called?
- A. Renin
- B. Antidiuretic hormone
- C. Atrial natriuretic
- D. Insulin
Correct answer: A
Rationale: Renin is the correct answer. When arterial blood pressure decreases, the kidneys release renin, which triggers a series of reactions ultimately leading to an increase in blood pressure and peripheral resistance. Antidiuretic hormone (choice B) is involved in water retention, atrial natriuretic hormone (choice C) promotes sodium excretion and lowers blood pressure, and insulin (choice D) regulates glucose metabolism, not blood pressure.
2. Nurse Isabelle enters the room of a client with a cognitive impairment disorder and asks what day of the week it is, what the date, month, and year are, and where the client is. The nurse is attempting to assess:
- A. confabulation.
- B. delirium.
- C. orientation.
- D. perseveration.
Correct answer: C
Rationale: The correct answer is C: "orientation." Nurse Isabelle is assessing the client's orientation by asking questions about time (day, date, month, year), place, and person. This assessment helps determine the client's awareness of their surroundings and situation. Confabulation (choice A) is the unintentional fabrication of details or events to fill in memory gaps and is not being assessed in this scenario. Delirium (choice B) is a state of acute confusion and disorientation, usually with a rapid onset, which is different from assessing orientation. Perseveration (choice D) refers to the persistent repetition of a response, statement, or behavior and is not the focus of the assessment being conducted by Nurse Isabelle in this situation.
3. What is the characteristic of the condition of leukemia?
- A. A benign growth of skin cells
- B. A malignant growth of skin cells
- C. A malignant growth of white blood cells
- D. A benign growth of white blood cells
Correct answer: C
Rationale: The correct answer is C: 'A malignant growth of white blood cells.' Leukemia is a type of cancer that affects the blood and bone marrow, leading to an overproduction of abnormal white blood cells. These cells are malignant and impair the normal function of healthy blood cells. Choices A, B, and D are incorrect because leukemia does not involve skin cells or benign growths; instead, it specifically refers to the abnormal proliferation of white blood cells.
4. An older adult patient has just sheared the skin on her elbow while attempting to boost herself up in bed, an event that has precipitated acute inflammation in the region surrounding the wound. Which of the following events will occur during the vascular stage of the patient's inflammation?
- A. Outpouring of exudate into interstitial spaces
- B. Chemotaxis
- C. Accumulation of leukocytes along epithelium
- D. Phagocytosis of cellular debris
Correct answer: A
Rationale: During the vascular stage of inflammation, there is an outpouring of exudate into the interstitial spaces, leading to swelling and edema. Choice B, chemotaxis, occurs during the cellular stage of inflammation, where leukocytes move to the site of injury in response to chemical signals. Choice C, accumulation of leukocytes along the epithelium, is not a typical event during the vascular stage. Phagocytosis of cellular debris, as in choice D, mainly occurs during the resolution stage of inflammation.
5. What is the cause of swelling during acute inflammation?
- A. Collagenase
- B. Fluid exudate
- C. Lymphocytic margination
- D. Anaerobic glycolysis
Correct answer: B
Rationale: Swelling during acute inflammation is primarily caused by the accumulation of fluid exudate in the affected tissues. This fluid exudate contains proteins and cells that leak from blood vessels due to increased vascular permeability. Collagenase (Choice A) is an enzyme that breaks down collagen and is not directly responsible for swelling. Lymphocytic margination (Choice C) is the process where white blood cells line up along the blood vessel walls, which does not directly cause swelling. Anaerobic glycolysis (Choice D) is a metabolic process that occurs in the absence of oxygen and is not related to the mechanism of swelling in acute inflammation.
