Question 1 Report
Fig. 1 shows a nurse measuring the blood pressure of a person during a workplace health check. The monitor displays 128/82 mmHg.
(a) Name the type of blood vessel in the upper arm where blood pressure is measured. [1]
(b) Describe what the two values 128 and 82 represent. [2]
(c) Give two changes in lifestyle that could help a person with persistently high blood pressure. [2]
(d) Explain why high blood pressure can make the heart work harder. [1]
Answer Details
(a) Blood pressure is measured in an artery. [1]
(b) The value 128 mmHg is the pressure when the ventricles contract, called systolic pressure. The value 82 mmHg is the pressure when the ventricles relax, called diastolic pressure. [2]
(c) Suitable lifestyle changes include reducing salt intake and exercising regularly. Maintaining or reaching a healthy body mass, stopping smoking, and reducing alcohol intake are also acceptable. Any two gain credit. [2]
(d) With high blood pressure, the heart has to pump blood against greater pressure or resistance, so it works harder. [1]
