Cardiovascular System Exam Questions And Answers
1. What procedure uses a catheter to open blocked coronary arteries and improve blood flow to the heart muscle?
- A. Angioplasty
- B. Stent placement
- C. Coronary artery bypass graft (CABG)
- D. Valve replacement
Correct answer: A
Rationale: The correct answer is A, Angioplasty. Angioplasty is a procedure where a catheter is used to open blocked coronary arteries and may involve the insertion of a stent to improve blood flow to the heart muscle. Stent placement (B) is a related procedure but specifically refers to the insertion of a stent. Coronary artery bypass graft (CABG) (C) is a surgical procedure that uses blood vessels to bypass blocked coronary arteries. Valve replacement (D) is a different procedure that involves replacing a heart valve, not opening blocked coronary arteries.
2. When children are research participants, __________.
- A. Investigators need to seek the opinion of others if in doubt about the harmful effects of research.
- B. They have the right to concealment of their identity on information collected in the course of research.
- C. There is a need to inform them or their parents of the results of the research.
- D. Informed consent of their parents as well as others who act on their behalf should be obtained.
Correct answer: D
Rationale: When children are research participants, it is essential to obtain informed consent from their parents or others who act on their behalf. This is to ensure that the child's rights and well-being are protected during the research process. Informed consent is a fundamental ethical principle in research involving children, as they may not have the capacity to fully understand the implications of their participation. Choice A is incorrect because seeking the opinion of others when in doubt about harmful effects is not a substitute for informed consent. Choice B is incorrect because children do not have an absolute right to conceal their identity in research, especially when it comes to ensuring their safety and well-being. Choice C is incorrect as it is important to inform children or their parents about the results of the research to maintain transparency and respect for their participation.
3. A client scheduled for surgery cannot sign the operative consent form because he has been sedated with opioid analgesics. The nurse should take which best action regarding the informed consent?
- A. Obtain a court order for the surgery
- B. Sign the informed consent on behalf of the client
- C. Send the client to surgery without the consent form being signed
- D. Obtain a telephone consent from a family member, with the consent being witnessed by two healthcare providers
Correct answer: D
Rationale: In situations where a client is unable to sign the consent form, obtaining a telephone consent from a family member, with the consent being witnessed by two healthcare providers, is the best course of action. This ensures that the client's best interests are considered and that proper authorization is obtained. Option A, obtaining a court order, is not necessary in this scenario and could delay the surgery. Option B, signing the consent on behalf of the client, is not appropriate as it may raise ethical and legal concerns. Option C, sending the client to surgery without a signed consent form, is not advisable as it violates the principles of informed consent and places the client at risk.
4. Freud's psychosexual stage that occurs between the ages of 3 and 5 is the ________ stage.
- A. oral
- B. anal
- C. phallic
- D. genital
Correct answer: C
Rationale: Freud's psychosexual stage that occurs between the ages of 3 and 5 is the phallic stage. During this stage, children focus on the genitals and start to identify with the same-sex parent while developing the superego. Choice A, the oral stage, occurs during infancy (0-1 year), where gratification is centered around the mouth. Choice B, the anal stage, occurs between the ages of 1 and 3, focusing on toilet training. Choice D, the genital stage, is the final stage in Freud's theory, occurring from puberty onwards, where the focus is on mature sexual relationships.
5. What role does culture play in the development of psychopathology?
- A. Culture has little impact on psychopathology.
- B. Culture is crucial in understanding the development of psychopathology.
- C. Culture has a moderate impact on the development of psychopathology.
- D. Culture determines the onset of psychopathology.
Correct answer: B
Rationale: Culture is crucial in understanding the development of psychopathology. It influences beliefs, norms, values, and behaviors, which can significantly impact the manifestation and understanding of psychopathological conditions. Choice A is incorrect because culture does have a substantial impact on psychopathology. Choice C is not as strong as choice B in emphasizing the significance of culture. Choice D is incorrect as culture is one of many factors influencing the onset of psychopathology, not the sole determinant.
