1. In which of the following conditions might increased cortisol levels be found?

• A. Cushing's syndrome
• B. Addison's disease
• C. Renal failure
• D. Congestive heart failure

Correct answer: A

Rationale: Cushing's syndrome is characterized by increased cortisol levels due to the overproduction of cortisol by the adrenal glands. This excess cortisol can lead to various symptoms and complications. Addison's disease is associated with decreased cortisol levels as it results from adrenal insufficiency, making it an incorrect choice in this context. Renal failure and congestive heart failure are not typically linked to abnormal cortisol levels, further indicating that they are not the conditions where increased cortisol levels are found.

2. Which of the following represents a normal serum potassium level?

• A. 1.5 mEq/L
• B. 3.0 mEq/L
• C. 4.0 mEq/L
• D. 6.0 mEq/L

Correct answer: C

Rationale: The correct answer is 4.0 mEq/L. Normal serum potassium levels typically range from 3.5-5.5 mEq/L. Choice A (1.5 mEq/L) is below the normal range, Choice B (3.0 mEq/L) is also below the normal range, and Choice D (6.0 mEq/L) is above the normal range. Therefore, the only option within the normal range is Choice C (4.0 mEq/L).

3. The nurse is teaching a client about communicable diseases and explains that a portal of entry is:

• A. a vector.
• B. a source, like contaminated water.
• C. food.
• D. the respiratory system.

Correct answer: D

Rationale: The correct answer is 'the respiratory system.' A portal of entry is the path through which a microorganism enters the body. In the case of communicable diseases, the respiratory system can serve as a portal of entry for pathogens such as viruses or bacteria. Choices A, B, and C are incorrect. A 'vector' is an organism that transmits disease, not the entry point for pathogens. Contaminated water or food can act as sources or reservoirs of disease-causing microorganisms, not portals of entry.

4. The nurse acts as an advocate for the nursing profession by performing all of the following activities except:

• A. encouraging political involvement by nurses with their legislators.
• B. acting as a first-aid provider for a children's athletic team.
• C. precepting newly licensed nurses in the work situation.
• D. encouraging as many persons to become nurses as possible.

Correct answer: D

Rationale: The nurse acts as an advocate for the nursing profession by encouraging appropriate persons to become nurses, by being a positive role model and mentor, and by communicating the needs of nurses in the most professional manner possible to those making the laws. Encouraging as many persons as possible to become nurses may not align with the advocacy role, as the focus should be on quality rather than quantity. Choices A, B, and C are activities that align with being an advocate for the nursing profession by promoting political involvement, providing first aid, and precepting newly licensed nurses, respectively.

5. What is a predisposing factor for cancer of the tongue?

• A. tobacco use
• B. obesity
• C. sun exposure
• D. eating sweets

Correct answer: A

Rationale: Tobacco use is a well-established predisposing factor for cancer of the tongue. Smoking or chewing tobacco can lead to the development of oral cancers, including those affecting the tongue. Obesity, sun exposure, and eating sweets are not directly linked to an increased risk of tongue cancer. Obesity may be associated with other types of cancer, sun exposure can lead to skin cancer, and eating sweets is not a known risk factor for tongue cancer. Therefore, the correct answer is tobacco use, as it has a strong association with the development of tongue cancer, making it a significant predisposing factor.
