1. When performing CPR, at what rate should chest compressions be applied?

A. 100 per minute
B. 60 per minute
C. As quickly as possible
D. 200 per minute

Correct answer: A

Rationale: During CPR, chest compressions should be applied at a rate of 100 compressions per minute in order to effectively circulate blood and oxygen to vital organs. Option A, '100 per minute,' is the correct answer as it aligns with the recommended compression rate in CPR guidelines. Option B, '60 per minute,' is incorrect as it is too slow and may not provide adequate circulation. Option C, 'As quickly as possible,' is vague and does not specify the recommended compression rate. Option D, '200 per minute,' is incorrect as it exceeds the recommended rate and may not be as effective in maintaining perfusion.

2. Mr. Thomas is a well-groomed 68-year-old male patient who had prostate surgery two days ago. He has an indwelling catheter and a urinary drainage bag. You have weighed him at 9 am each morning for 3 mornings in a row. Today, on the 4th day, his morning weight is 3 pounds more than it was the day before. Why could he have gained these 3 pounds in one day, on a 1000 calorie diet?

A. It is obvious that his visitors have been sneaking him junk food from the local fast-food restaurant.
B. It may be that his urinary drainage bag was not emptied today and it was emptied on previous days.
C. It is obvious that the scale is broken and it should be replaced immediately to prevent these false weights.
D. A 3-pound weight gain is not significant enough to question and should just be noted.

Correct answer: B

Rationale: The correct answer is that the weight gain may be due to the urinary drainage bag not being emptied today, while it was emptied on previous days. This scenario is common and can lead to an increase in weight that is not related to food intake. Choice A is incorrect because assuming visitors are sneaking junk food is speculative and not based on facts. Choice C is incorrect as there is no evidence to suggest the scale is broken. Choice D is incorrect because any unexplained weight gain should be investigated further, even if it seems insignificant at first.

3. The nurse is reviewing the hot/cold theory of health and illness. Which statement best describes the basic tenets of this theory?

A. The causation of illness is based on supernatural forces that influence the humors of the body.
B. Herbs and medicines are classified based on their physical characteristics of hot and cold and the humors of the body.
C. The four humors of the body consist of blood, yellow bile, black bile, and phlegm.
D. The treatment of disease consists of adding or subtracting cold, heat, dryness, or wetness to restore the balance of the humors of the body.

Correct answer: D

Rationale: The hot/cold theory of health and illness is based on the four humors of the body: blood, phlegm, black bile, and yellow bile. These humors regulate the basic bodily functions, described in terms of temperature, dryness, and moisture. The treatment of disease in this theory involves adding or subtracting cold, heat, dryness, or wetness to restore the balance of the humors. Choice A is incorrect as the theory is not based on supernatural forces but on the balance of bodily humors. Choice B is incorrect as herbs and medicines are not classified solely based on their physical characteristics of hot and cold in this theory. Choice C is incorrect as the four humors are blood, phlegm, black bile, and yellow bile, not spiritual connectedness or social aspects. Therefore, the correct choice is D, as it accurately reflects a foundational tenet of the hot/cold theory of health and illness.

4. Which of the following may represent an upper airway obstruction?

A. Retractions
B. Elongated expiratory phase
C. Stridor
D. Expiratory wheezing

Correct answer: C

Rationale: Stridor is the sound produced by turbulent airflow through a partially obstructed upper airway. It is a classic sign of upper airway obstruction. While an elongated expiratory phase may indicate lower airway obstruction, stridor specifically points to an upper airway issue. Retractions are also often seen in upper airway obstruction due to the increased effort of breathing. Expiratory wheezing, on the other hand, is more indicative of lower airway conditions such as asthma or chronic obstructive pulmonary disease (COPD).

5. Many Asians believe in the yin/yang theory, which is rooted in the ancient Chinese philosophy of Tao. Which statement most accurately reflects this philosophy's view of "health"??

A. A person is able to work and produce.
B. A person is happy, stable, and feels good.
C. All aspects of the person are in perfect balance.
D. A person is able to care for others and function socially.

Correct answer: C

Rationale: In the yin/yang theory rooted in ancient Chinese philosophy, health is believed to exist when all aspects of a person are in perfect balance. This includes physical, mental, emotional, and spiritual well-being. Choice C accurately reflects this philosophy's view of health. Choices A, B, and D do not capture the essence of the yin/yang theory. Being able to work and produce, being happy and stable, or caring for others and functioning socially, while important, do not encompass the holistic balance emphasized in the yin/yang theory.
