Final answer:
Alex has a cardiovascular system issue, as indicated by his abnormal blood pressure of 135/90 mm Hg, and should take steps to lower it to reduce the risk of cardiovascular disorders.
Step-by-step explanation:
The correct option is B) Cardiovascular system, blood pressure. Alex's blood pressure is 135/90 mm Hg, which is higher than the normal range of 90/60 to 120/80 mm Hg. This indicates that the cardiovascular system is involved. The systolic pressure is the first number (135 mm Hg), which describes the pressure when the heart's ventricles contract and pump blood out. The diastolic pressure is the second number (90 mm Hg), which is the pressure when the ventricles relax and fill with blood. High blood pressure, or hypertension, can lead to cardiovascular disorders and puts stress on the heart, so lowering it is beneficial to Alex's health. Lifestyle changes such as regular cardio exercise, dietary adjustments, and stress management practices can help in reducing blood pressure.
The body system involved in this case is the Cardiovascular system. The vital signs that are abnormal for Alex are blood pressure.
Alex's blood pressure reading of 135/90 mm Hg is considered high. Normal blood pressure is typically between 90/60 and 120/80 mm Hg.
The number 135 in the blood pressure reading refers to the systolic pressure, which is the pressure in the arteries when the heart beats and pumps out blood. The number 90 refers to the diastolic pressure, which is the pressure in the arteries when the heart is at rest between beats.
Alex's doctor would like him to lower his blood pressure because high blood pressure puts strain on the cardiovascular system and increases the risk of heart disease. Some ways to lower blood pressure include maintaining a healthy weight, exercising regularly, eating a balanced diet low in sodium and high in fruits and vegetables, reducing stress, and avoiding smoking and excessive alcohol consumption.
