1. Which of the following terms describes the amount of blood ejected per heartbeat?
- A. Stroke volume
- B. Cardiac output
- C. Ejection fraction
- D. Afterload
Correct answer: A
Rationale: The correct answer is A: Stroke volume. Stroke volume refers to the amount of blood ejected by the left ventricle in one contraction. Choice B, Cardiac output, is the total volume of blood pumped by the heart per minute and is calculated by multiplying stroke volume by heart rate. Choice C, Ejection fraction, is the percentage of blood pumped out of the left ventricle with each heartbeat. Choice D, Afterload, refers to the pressure or resistance that the ventricles must overcome to eject blood during systole. Therefore, in the context of the question, the term that specifically describes the amount of blood ejected per heartbeat is stroke volume.
2. When surgery is on-going, who coordinates the activities outside, including the family?
- A. Orderly/clerk C. Circulating Nurse
- B. Nurse Supervisor D. Anesthesiologist
- C.
- D.
Correct answer: B
Rationale: Nursing interventions should be grounded in a deep understanding of the physiological processes involved, ensuring that care provided is both effective and efficient.
3. Substance abuse is different from substance dependence in that, substance dependence:
- A. includes characteristics of adverse consequences and repeated use
- B. requires long term treatment in a hospital based program
- C. produces less severe symptoms than that of abuse
- D. includes characteristics of tolerance and withdrawal
Correct answer: D
Rationale: Understanding the underlying pathology and therapeutic techniques ensures that nursing care is not only reactive but also preventative, reducing the risk of complications.
4. The recommended daily fluid intake of patients maintained using hemodialysis is:
- A. 150 mL plus the volume of urinary output
- B. 500 mL plus the volume of urinary output
- C. 1000 mL plus the volume of urinary output
- D. 1500 mL plus the volume of urinary output
Correct answer: C
Rationale: The correct answer is C: 1000 mL plus the volume of urinary output. Fluid intake is typically restricted in hemodialysis patients to prevent fluid overload. The recommended daily fluid intake for these patients is 1000 mL plus any urinary output. Choice A (150 mL plus the volume of urinary output) is too low and would not provide enough fluid for these patients. Choice B (500 mL plus the volume of urinary output) is also insufficient. Choice D (1500 mL plus the volume of urinary output) is too high and may lead to fluid overload in hemodialysis patients.
5. Which food item interferes with the effectiveness of warfarin?
- A. Cauliflower
- B. Zucchini
- C. Green beans
- D. Broccoli
Correct answer: D
Rationale: Broccoli is high in vitamin K, which can affect the effectiveness of warfarin. Warfarin is an anticoagulant medication that functions by reducing the activity of vitamin K in the body. When one consumes broccoli, which is rich in vitamin K, it could counteract the anticoagulant effect of warfarin, thereby interfering with its effectiveness. On the other hand, cauliflower, zucchini, and green beans do not have significant levels of vitamin K and hence, are not known to impact the effectiveness of warfarin.
