Verified step by step guidance

1. Understand the concept of an observation: In scientific terms, an observation is a statement based on something that is directly seen, heard, or measured, without interpretation or assumption.
2. Analyze each statement to determine if it is an observation: Look for statements that describe a direct measurement or sensory experience.
3. Evaluate the first statement: 'Repeated studies show that lowering sodium in one's diet will lead to a decrease in blood pressure.' This is a conclusion drawn from studies, not a direct observation.
4. Evaluate the second statement: 'During an assessment in the doctor's office, the nurse records that the patient's resting pulse as 32 beats per minute.' This is a direct measurement and thus qualifies as an observation.
5. Evaluate the remaining statements: The third and fourth statements involve beliefs or interpretations, which are not direct observations. Therefore, the second statement is the correct example of an observation.
