1. What is the main purpose of health informatics?
- A. To manage patient care
- B. To store patient records
- C. To enhance clinical decision making
- D. To improve healthcare policies
Correct answer: C
Rationale: The main purpose of health informatics is to enhance clinical decision making. While managing patient care (choice A) and storing patient records (choice B) are important functions within health informatics, the primary goal is to improve decision making processes by utilizing technology and data. Improving healthcare policies (choice D) is not the main purpose of health informatics, although it can be a byproduct of better-informed decision making.
2. The origin of the term 'anatomy' is related to
- A. the Greek word for 'function.'
- B. the name of the first anatomist.
- C. the Greek word for 'cutting up.'
- D. the function of internal organs.
Correct answer: the Greek word for 'cutting up.'
Rationale: The correct answer is C: the Greek word for 'cutting up.' The term 'anatomy' originates from the Greek words 'ana' (up) and 'temnein' (to cut), which means 'cutting up' or 'dissection.' This term refers to the process of dissecting bodies to study their structure. Choices A, B, and D are incorrect because 'anatomy' is not related to the Greek word for 'function,' the name of the first anatomist, or the function of internal organs, but rather to the act of cutting up for study and examination.
3. The client has a do-not-resuscitate (DNR) order. The family asks the nurse to ignore the DNR if the client codes. What is the nurse's responsibility?
- A. Follow the family's wishes
- B. Explain that the DNR must be honored
- C. Ignore the DNR and proceed with CPR
- D. Perform CPR if the client codes
Correct answer: B
Rationale: The correct answer is B: 'Explain that the DNR must be honored.' The nurse's responsibility is to follow the DNR order, as it is a legal and ethical obligation. Choice A is incorrect because following the family's wishes would go against the established DNR order. Choice C is incorrect as ignoring the DNR order is not appropriate. Choice D is also incorrect as performing CPR would be contrary to the client's expressed wishes in the DNR order.
4. 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.
5. What intervention is needed for a patient with a chest tube and an air leak?
- A. Tighten the connections of the chest tube system
- B. Replace the chest tube
- C. Clamp the chest tube
- D. Continue to monitor the chest tube
Correct answer: A
Rationale: The correct intervention for a patient with a chest tube and an air leak is to tighten the connections of the chest tube system. This step helps prevent air leaks and ensures the proper functioning of the chest tube. Choice B, replacing the chest tube, is not necessary as tightening the connections should be attempted first. Clamping the chest tube (Choice C) is not recommended as it can lead to complications by obstructing the drainage system. Continuing to monitor the chest tube (Choice D) without taking action may result in worsening of the air leak. Therefore, the priority intervention is to tighten the connections of the chest tube system.
