Cardiovascular System Exam Questions
1. What test measures the electrical activity of the heart over a period of time, typically 24 to 48 hours?
- A. Holter monitor
- B. Echocardiogram
- C. Stress test
- D. Arterial blood gas (ABG)
Correct answer: A
Rationale: The correct answer is A, Holter monitor. A Holter monitor is a portable device that records the electrical activity of the heart over a period of 24 to 48 hours. It is used to detect arrhythmias and other heart conditions. Choice B, Echocardiogram, is a test that uses sound waves to create images of the heart's structure and function, not focused on the electrical activity. Choice C, Stress test, evaluates the heart's function under stress but does not monitor electrical activity over an extended period. Choice D, Arterial blood gas (ABG), measures the levels of oxygen and carbon dioxide in the blood, unrelated to measuring the electrical activity of the heart over time.
2. Dr. Torrez believes that how conflicts between biological drives and social expectations are resolved determines the person's ability to learn, to get along with others, and to cope with anxiety. Dr. Torrez accepts the __________.
- A. psychoanalytic perspective
- B. psychosocial theory
- C. cognitive-developmental theory
- D. social learning theory
Correct answer: A
Rationale: Dr. Torrez's belief about conflicts between biological drives and social expectations influencing a person's ability to learn, get along with others, and cope with anxiety aligns with the psychoanalytic perspective. This perspective, developed by Sigmund Freud, focuses on the unconscious mind, early childhood experiences, and the resolution of inner conflicts as important factors in shaping personality and behavior. The other choices are incorrect because psychosocial theory, cognitive-developmental theory, and social learning theory do not specifically focus on conflicts between biological drives and social expectations as central to understanding human behavior and development.
3. What should the nurse do if a patient experiences abdominal cramping during enema administration?
- A. Lower the height of the solution container
- B. Increase the flow of the enema solution
- C. Stop the procedure and remove the tubing
- D. Continue the enema at a slower rate
Correct answer: A
Rationale: When a patient experiences abdominal cramping during enema administration, the nurse should lower the height of the solution container. This adjustment can help alleviate the cramping by reducing the speed and pressure of the solution entering the colon. Increasing the flow of the enema solution (Choice B) can exacerbate the cramping. Stopping the procedure and removing the tubing (Choice C) may be necessary in extreme cases but is not the initial step. Continuing the enema at a slower rate (Choice D) may not effectively address the cramping, making it less optimal than lowering the height of the solution container.
4. What is the common denominator of all forms of heart failure?
- A. Pulmonary edema
- B. Jugular venous distention
- C. Peripheral edema
- D. Reduced cardiac output
Correct answer: D
Rationale: The correct answer is D: Reduced cardiac output. All forms of heart failure share the common denominator of reduced cardiac output, which leads to inadequate tissue perfusion. Pulmonary edema (choice A) is a consequence of heart failure but not the common denominator. Jugular venous distention (choice B) and peripheral edema (choice C) are signs of heart failure but do not represent the common denominator shared by all forms.
5. A client has a history of excessive drinking, which has led to multiple arrests for driving under the influence (DUI). The client states, 'I work hard to provide for my family. I don't see why I can't drink to relax.' The nurse recognizes the use of which defense mechanism?
- A. Projection
- B. Rationalization
- C. Regression
- D. Sublimation
Correct answer: B
Rationale: The correct answer is Rationalization. The client is using rationalization as a defense mechanism by justifying their excessive drinking as a way to relax due to working hard to provide for their family. Rationalization involves creating logical excuses to justify unacceptable feelings or behaviors. Projection involves attributing one's unacceptable feelings or thoughts to others. Regression is reverting to an earlier stage of development in the face of unacceptable thoughts or impulses. Sublimation is the channeling of unacceptable impulses into socially acceptable activities.
