1. Which of the following lab values is associated with a decreased risk of cardiovascular disease?

• A. high HDL cholesterol
• B. low HDL cholesterol
• C. low total cholesterol
• D. low triglycerides

Correct answer: B

Rationale: High HDL cholesterol is associated with a decreased risk of cardiovascular disease because HDL cholesterol is known as 'good' cholesterol. It helps remove other forms of cholesterol, like LDL cholesterol, from the bloodstream, reducing the risk of plaque buildup in the arteries. Low HDL cholesterol (Choice B) is actually a risk factor for cardiovascular disease because it means there is less of the 'good' cholesterol to perform its protective functions. Low total cholesterol (Choice C) and low triglycerides (Choice D) are not necessarily associated with a decreased risk of cardiovascular disease, as the balance and types of cholesterol play a more crucial role in heart health.

2. A test that can correctly identify those who do not have a given disease is:

• A. specific.
• B. sensitive.
• C. negative culture
• D. marginal finding.

Correct answer: A

Rationale: The correct answer is 'specific.' Specificity refers to the ability of a test to correctly identify individuals who do not have a particular disease. In this case, when the client's lab culture report is negative for the suspected infection, a specific test would correctly identify that the client does not have the disease. 'Sensitive' (Choice B) is incorrect as sensitivity refers to the ability of a test to correctly identify individuals who do have the disease. 'Negative culture' (Choice C) is incorrect as it does not describe the test's ability but rather the result itself. 'Marginal finding' (Choice D) is irrelevant to the concept being tested in this question.

3. A client is told that his test is positive, but in fact, the client does not have the disease tested for. Which type of false report is this an example of?

• A. positive
• B. false positive
• C. negative
• D. false negative

Correct answer: B

Rationale: The correct answer is 'false positive.' A false-positive result occurs when a test result is labeled positive in error, when the actual result is negative. In this scenario, the client received a positive test result incorrectly, as he does not have the disease being tested for. Choice A ('positive') is too vague and does not specify that the result was incorrect. Choice C ('negative') is the opposite of what happened in the scenario. Choice D ('false negative') refers to a situation where a test result is labeled negative incorrectly, which is not the case in this scenario.

4. 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.

5. A nurse is planning client assignments for the day. Which task should the nurse assign to the nursing assistant (unlicensed assistive personnel)?

• A. Recording the urinary output for a client with renal calculi whose urine must be strained
• B. Dressing change instructions for a client who had a mastectomy 2 days ago
• C. Reporting abnormal lab values to the health care provider for a client scheduled for a laparoscopic cholecystectomy
• D. Preprocedural teaching for a client scheduled for a cardiac stress test

Correct answer: A

Rationale: The nurse is legally responsible for client assignments and must assign tasks based on state nursing practice act guidelines and job descriptions provided by the employing agency. The nursing assistant is trained to measure, collect, and strain urine, making recording urinary output for a client with renal calculi a suitable task for the nursing assistant. This task falls within the nursing assistant's role description. Dressing change instructions for a client who had a mastectomy involve a higher level of skill and knowledge, beyond the scope of a nursing assistant. Reporting abnormal lab values to the health care provider for a client scheduled for a laparoscopic cholecystectomy requires interpretation and clinical judgment, which is typically not within the nursing assistant's role. Preprocedural teaching for a client scheduled for a cardiac stress test involves providing detailed information and education, which is usually the responsibility of a licensed nurse or other qualified healthcare provider.
