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.

While physicians and nurses play essential roles in patient care, they are not typically the primary professionals involved in monitoring drug-nutrient interactions. Therefore, choices A, B, and C are incorrect.

A. Palm oil
B. Peanut oil

Correct answer: C

Rationale: Canola oil is lower in saturated fats compared to palm oil, peanut oil, and stick margarine, making it a healthier option for clients at risk for heart disease. Palm oil is high in saturated fats, peanut oil has a moderate amount of saturated fats, and stick margarine is also high in saturated fats and trans fats, which are not heart-healthy choices.
