Nursing Elites

1. A nurse is caring for a client who has cancer and is receiving total parenteral nutrition (TPN). Which of the following lab values indicates the treatment is effective?

• A. Hct 43%
• B. WBC 8,000/uL
• C. Albumin 4.2 g/dL
• D. Calcium 9.4 mg/dL

Correct answer: C

Rationale: The correct answer is Albumin 4.2 g/dL. Albumin is a protein produced by the liver and is a key indicator of nutritional status. In a client receiving total parenteral nutrition (TPN), an increase in albumin level indicates that the treatment is effective in providing adequate nutrition support. Hct (hematocrit), WBC (white blood cell count), and calcium levels are not direct indicators of the effectiveness of TPN in this context.

2. Which type of fatty acid has carbon atoms connected by two or more double bonds?

• A. Saturated fatty acids
• B. Monounsaturated fatty acids
• C. Trans fatty acids
• D. Polyunsaturated fatty acids

Correct answer: D

Rationale: The correct answer is D. Polyunsaturated fatty acids. Polyunsaturated fatty acids have two or more double bonds in their carbon chains, making them less stable and more prone to oxidation. This characteristic distinguishes them from saturated fatty acids (Choice A), which have single bonds between carbon atoms providing stability. Monounsaturated fatty acids (Choice B) contain only one double bond, and trans fatty acids (Choice C) can have varying numbers of double bonds but are not specifically defined by having two or more double bonds.

3. 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.

4. A client with a body mass index of 28 is seeking dietary advice. Which of the following actions should the nurse take?

• A. Encourage the client to continue their current daily caloric intake.
• B. Recommend a total fiber intake of 12g per day.
• C. Advise the client to add 500 calories per day to their diet.
• D. Refer the client to a weight-loss support group.

Correct answer: D

Rationale: Referring the client to a weight-loss support group is the most appropriate action for a client with a body mass index of 28. This action can provide the necessary support, guidance, and motivation to help the client achieve their weight loss goals. Encouraging the client to continue their current daily caloric intake (Choice A) may not address the need for weight loss. Recommending a total fiber intake of 12g per day (Choice B) is important for overall health but may not directly address weight loss. Advising the client to add 500 calories per day to their diet (Choice C) would not be beneficial for weight loss in this scenario.

5. Compared to the typical American diet, what does the DASH diet provide more of?

• A. More saturated fats
• B. Fewer whole grains
• C. More fruits and vegetables
• D. Fewer dairy products

Correct answer: C

Rationale: The correct answer is C. The DASH diet, which stands for Dietary Approaches to Stop Hypertension, emphasizes the consumption of fruits and vegetables, which are high in potassium, fiber, and antioxidants. These nutrients help lower blood pressure. Therefore, compared to the typical American diet, the DASH diet provides more fruits and vegetables. Choices A, B, and D are incorrect. The DASH diet doesn't focus on providing more saturated fats or fewer whole grains or dairy products. In fact, it encourages the consumption of whole grains and low-fat dairy products to promote a balanced and healthy diet.
