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 nurse is caring for a client who is receiving parenteral nutrition. Which of the following findings indicates the therapy is effective?

A. Client has soft, formed bowel movements.
B. Client’s mucous membranes are pink.
C. Client reports ability to complete ADLs.
D. Client’s blood glucose level is within the expected reference range.

Correct answer: D

Rationale: The correct answer is D because having a blood glucose level within the expected reference range indicates that parenteral nutrition is effectively meeting the client's nutritional needs. Choices A, B, and C are incorrect because soft, formed bowel movements, pink mucous membranes, and the ability to complete activities of daily living do not directly reflect the effectiveness of parenteral nutrition therapy.

5. A healthcare provider is evaluating a client who reports paresthesia of the hands and feet. The provider should identify this manifestation as an indication of which of the following dietary deficiencies?

A. Iron
B. Riboflavin
C. Vitamin C

Iron deficiency is more commonly associated with anemia symptoms like fatigue and pallor. Riboflavin deficiency can cause mouth and skin changes. Vitamin C deficiency is linked to scurvy symptoms like bleeding gums and easy bruising.
