Activity 1

Data Table 1

Pulse Point	Palpated (yes/no)?	Notes
Temporal
Carotid
Radial
Brachial
Popliteal

Which arterial pulse was easiest to feel? Explain your answer.

Data Table 2

Pulse Point	1-Minute Count	15-Second Count	15-Second Count x 4
Radial
Pulse point of choice (indicate which):

Would it be more accurate to measure the pulse for 15 seconds or for a full minute? Explain your answer.

Radial
Pulse point of choice (indicate which):

Data Table 4

Pulse Point	1-Minute Count

Pulse point of choice (indicate which):

Compare your results for Data Tables 3 and 4. Were the number of heart beats per minute approximately the same for each position, standing vs. supine? Why or why not?

Activity 2

Data Table 5

1-Minute Count	15-Second Count	15-Second Count x 4	Cardiac output (CO)

Activity 3

Data Table 6

Arm position	Systolic pressure	Diastolic pressure
Level with the heart
Lower than the heart
Above the heart

Based on your results, was there a difference in blood pressure readings depending on the position of the arm? Explain your answer. Which arm position would provide the most accurate blood pressure reading?

Based on the results reported in Data Table 6, what is your systolic/diastolic blood pressure reading, and would it be considered normal, high, or prehypertension?

Data Table 7

Pressure	Value
Systolic pressure
Diastolic pressure

Activity 4

Data Table 8

RR Interval (small squares)	RR Interval Duration (seconds)	Heart Rate (bpm)

Based on the results reported in Data Table 8, does the person have a heart rate in the normal range for an adult at rest? If not, in what way does it vary from normal?
