1. In the recent technological innovations, which of the following describe researches that are made to improve and make human life easier?
- A. Pure research
- B. Basic research
- C. Applied research
- D. Experimental research
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.
2. What is the movement of water from an area of lower solute concentration to one of higher solute concentration called?
- A. Hypodipsia
- B. Hypernatremia
- C. Hypokalemia
- D. Osmosis
Correct answer: D
Rationale: The correct answer is D, Osmosis. Osmosis is the process where water moves from an area of low solute concentration to an area of high solute concentration. This movement equalizes the solute concentration in intracellular and extracellular fluids. Choices A, B, and C are incorrect because they do not describe the movement of water based on solute concentration levels.
3. 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.
4. The RR nurse should monitor for the most common postoperative complication of:
- A. hemorrhage
- B. endotracheal tube perforation
- C. osopharyngeal edema
- D. epiglottis
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.
5. When a nurse signs a consent form, which ethical principle is being observed regarding the patient?
- A. Autonomy
- B. Justice
- C. Accountability
- D. Beneficence
Correct answer: A
Rationale: The correct answer is 'Autonomy'. Autonomy refers to the patient's right to make their own decisions, which is being honored when a nurse signs a consent form. While beneficence (Choice D) is an important ethical principle that involves acting in the patient's best interest, it is not what is being primarily observed in this instance. Justice (Choice B) refers to fairness and equal treatment and is not specifically relevant to this scenario. Accountability (Choice C) pertains to being answerable for one's actions and decisions, but again, it is not the principle directly observed in this situation. Therefore, when a nurse signs a consent form, it is the principle of autonomy that is being observed.
