1. Why is atherosclerosis dangerous to arterial function?
- A. It diminishes central circulation
- B. It causes decreased blood pressure on artery walls
- C. It narrows the arterial lumen so a clot can easily block it
- D. It increases arterial elasticity
Correct answer: C
Rationale: Atherosclerosis is dangerous to arterial function because it narrows the arterial lumen, increasing the risk of a clot completely blocking the blood flow. This can lead to severe cardiovascular events such as heart attacks or strokes. Choice A is incorrect since atherosclerosis does not primarily diminish central circulation, but rather, it impedes local blood flow where the plaque is present. Choice B is also incorrect as atherosclerosis increases the pressure on artery walls due to the narrowed space for blood flow, not decrease it. Lastly, choice D is incorrect as atherosclerosis causes the arteries to lose their elasticity, not increase it.
2. Which vitamin deficiency is most likely to cause bleeding disorders?
- A. Vitamin A
- B. Vitamin E
- C. Vitamin K
- D. Vitamin D
Correct answer: C
Rationale: Vitamin K is essential for blood clotting as it plays a crucial role in the activation of clotting factors. Deficiency of Vitamin K can lead to impaired blood clotting, resulting in bleeding disorders. Vitamin A is more associated with vision and skin health, not blood clotting. Vitamin E is known for its antioxidant properties and role in immune function, not specifically related to bleeding disorders. Vitamin D plays a key role in calcium absorption and bone health, but it is not directly linked to blood clotting or bleeding disorders.
3. What is the most effective way to limit the number of microorganisms in the hospital?
- A. Using strict aseptic technique in all procedures
- B. Wearing a mask and gown when caring for all patients with communicable diseases
- C. Sterilizing all instruments
- D. Handwashing
Correct answer: A
Rationale: The most effective way to limit the number of microorganisms in the hospital is by using strict aseptic technique in all procedures. This approach ensures that the risk of introducing harmful microorganisms into the hospital environment or patients is minimized. Choice B, wearing a mask and gown when caring for patients with communicable diseases, is important but not as comprehensive as using aseptic technique in all procedures. Sterilizing all instruments (Choice C) is crucial for preventing infections but may not address all avenues of microorganism transmission. Handwashing (Choice D) is a fundamental practice in infection control but alone may not be as effective as utilizing aseptic techniques in all procedures to limit microorganisms in the hospital.
4. A client was rushed in the E.R showing a whitish, leathery and painless burned area on his skin. The nurse is correct in classifying this burn as:
- A. First degree burn C. Third degree burn
- B. Second degree burn D. Partial thickness burn
- 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.
5. The type of medicine that proposes that a person's inherent "life force" can foster self-healing is known as _____ medicine.
- A. homeopathic
- B. integrative
- C. naturopathic
- D. Ayurvedic
Correct answer: C
Rationale: Naturopathic medicine is based on the belief that a person's inherent "life force" can promote self-healing, often using natural therapies and lifestyle changes.
