Question: A patient has a blood pressure reading of 120/80 mmHg. If the systolic pressure increases by 10% and diastolic pressure decreases by 5%, what will be the new reading?

Options:

  1. 132/76
  2. 130/78
  3. 128/75
  4. 134/80

Correct Answer: 132/76

Solution: 

New systolic = 120 * 1.10 = 132 mmHg; New diastolic = 80 * 0.95 = 76 mmHg. New reading = 132/76.

Questions & Step-by-Step Solutions

A patient has a blood pressure reading of 120/80 mmHg. If the systolic pressure increases by 10% and diastolic pressure decreases by 5%, what will be the new reading?
  • Step 1: Identify the original systolic and diastolic pressures. The original systolic pressure is 120 mmHg and the original diastolic pressure is 80 mmHg.
  • Step 2: Calculate the new systolic pressure. To do this, increase the original systolic pressure by 10%. This means you multiply 120 mmHg by 1.10 (which is 100% + 10%). So, 120 * 1.10 = 132 mmHg.
  • Step 3: Calculate the new diastolic pressure. To do this, decrease the original diastolic pressure by 5%. This means you multiply 80 mmHg by 0.95 (which is 100% - 5%). So, 80 * 0.95 = 76 mmHg.
  • Step 4: Combine the new systolic and diastolic pressures to get the new blood pressure reading. The new reading is 132/76 mmHg.
  • Percentage Change – Understanding how to calculate percentage increases and decreases in numerical values.
  • Blood Pressure Readings – Knowledge of how blood pressure is represented and the significance of systolic and diastolic values.
