Answer :

To determine the expected blood pressure for a 15-year-old patient, let's evaluate the provided options and identify which one aligns with common medical guidelines.

Here are the options presented:

- a) 91/50
- b) 120/80
- c) 113/67
- d) 90/47

Let's analyze each option in the context of standard and healthy blood pressure values for adolescents:

1. Option a) 91/50
- This blood pressure reading is relatively low. While it might be plausible for some very athletic teenagers, it is not typically expected for the average 15-year-old.

2. Option b) 120/80
- This blood pressure reading is normal for an adult but may be considered slightly high for a 15-year-old. Adolescents often have lower blood pressure values compared to adults.

3. Option c) 113/67
- This reading falls within the range of normal blood pressure for a 15-year-old. It is neither too high nor too low, making it a balanced option that is expected for adolescent age.

4. Option d) 90/47
- This reading is quite low and usually would not be expected in a healthy 15-year-old without some specific health conditions or circumstances.

Given these observations, option c) 113/67 is the most appropriate and expected blood pressure for a 15-year-old patient.

Therefore, the correct answer is:
☐ a)
☐ b)
☑ c) 113/67
☐ d) 90/47
