1. What is the first step in the scientific method?

A. Conduct an experiment
B. Make an observation and ask a question
C. Formulate a hypothesis
D. Reach a consensus

Correct answer: B

Rationale: The first step in the scientific method is to make an observation and ask a question. This is because the scientific method is a systematic process of investigation that begins with observing a phenomenon or asking a question about it. This is followed by formulating a hypothesis (Choice C), designing and conducting an experiment to test the hypothesis (Choice A), and analyzing the results to reach a consensus or conclusion (Choice D). Therefore, choices A, C, and D are incorrect as they represent steps that occur after the initial observation and question.

2. A client is being taught how to follow a low-purine diet for gout management. Which statement indicates the client understands the teaching?

A. "I will need to limit the number of fruit servings each day."?
B. "I should avoid eating liver and other organ meats."?
C. "I can drink only white wine."?
D. "I should choose red meat instead of poultry."?

Correct answer: B

Rationale: The correct answer is B. Organ meats like liver are high in purines, which can exacerbate gout symptoms. Choosing to avoid such foods is essential in following a low-purine diet. Option A is incorrect because fruits are generally low in purines and are not usually restricted in a low-purine diet. Option C is incorrect as white wine, just like other types of alcohol, should be consumed in moderation or avoided due to its purine content. Option D is incorrect because red meat, including beef and lamb, is high in purines and should be limited in a low-purine diet.

3. Carmen discovers that the DASH diet contains more fiber and ____ compared to that of the typical American diet.

A. vitamin C
B. iron
C. potassium
D. sodium

Correct answer: C

Rationale: The correct answer is C: 'potassium.' The DASH diet is rich in potassium, which helps lower blood pressure, making it more effective than the typical American diet, which is often low in this essential mineral. Choice A, 'vitamin C,' is incorrect as the comparison is about fiber and another nutrient, not vitamin C. Choice B, 'iron,' is incorrect as the discussion is about fiber and a mineral that helps lower blood pressure, not iron. Choice D, 'sodium,' is incorrect as the DASH diet actually focuses on reducing sodium intake for better blood pressure control, so it wouldn't be a nutrient found in higher amounts compared to the typical American diet.

4. Major complications of diabetes include damage to the:

A. stomach, liver, and pancreas
B. eyes, nerves, and kidneys
C. skin, blood vessels, and lungs
D. brain, pituitary gland, and thyroid gland

Correct answer: B

Rationale: The correct answer is B: eyes, nerves, and kidneys. In diabetes, major complications result from damage to small blood vessels that supply these organs. Damage to the eyes can lead to retinopathy, to the nerves causing neuropathy, and to the kidneys causing nephropathy. Choices A, C, and D are incorrect as they do not represent the typical major complications associated with diabetes.

5. Which of the following terms refers to a process by which an individual receives education about the recognition of stress reactions and management strategies for handling stress, which may be instituted after a disaster?

A. Critical incident stress management
B. Follow-up
C. Debriefing
D. Defusion

Correct answer: A

Rationale: Critical incident stress management is a process that provides individuals with education about recognizing stress reactions and strategizing management techniques for handling stress after a disaster. Choice B, 'Follow-up', is incorrect because it generally refers to continuing care after initial treatment, not specifically to stress management education. Choice C, 'Debriefing', is a process where individuals involved in a critical event are brought together to discuss the event and their reactions to it. It can be part of the critical incident stress management process, but it doesn't cover the whole process. Choice D, 'Defusion', is a technique used in the immediate aftermath of a traumatic event to help individuals process their experiences, but it does not encompass the full range of education about stress recognition and management strategies.
