Question 1: Calculate the gradient of the blood sugar level change over time if the blood sugar increased from 80 mg/dL to 140 mg/dL over a period of 4 hours.

Answer: 15

Question 2: A patient’s heart rate drops from 90 bpm to 60 bpm over 15 minutes. What is the rate of change of heart rate per minute?

Answer: −2

Question 3: Plot the graph of blood pressure readings (systolic) taken at 8AM (120 mmHg) and 2PM (140 mmHg). Use the grid for graphing.

Answer:

Question 4: The number of days a patient takes medication is plotted against the reduction in symptoms. If symptoms decrease from 8 units to 2 units over 10 days, find the gradient of this change.

Answer: −0.6

Question 5: A medicine’s effectiveness is measured by the reduction of symptoms over days. If the symptoms decrease from 15 to 3 over 6 days, what is the gradient of this decrease?

Answer: -2

Question 6: A patient’s cholesterol level drops from 220 mg/dL to 180 mg/dL over 5 weeks. Calculate the weekly rate of change.

Answer: -8

Question 7: In a clinical trial, the blood pressure of a patient increases from 130 mmHg to 150 mmHg over 3 hours. Find the gradient of this change.

Answer: 6.67

Question 8: A medication causes a decrease in pain level from 9 to 4 over 8 hours. Determine the rate of change of pain level per hour.

Answer: -0.625

Question 9: Identify and correct the mistake: A student calculates the gradient as (140 - 80) / (4 - 0) = 70, but the actual change was from 80 mg/dL to 140 mg/dL over 4 hours.

Answer: Incorrect calculation, the actual gradient is (140 - 80) / (4 - 0) = 15, not 70.

Question 10: If a medication reduces blood sugar from 200 mg/dL to 150 mg/dL over 5 days, what is the average daily decrease in blood sugar levels?

Answer: -10

Question 11: A doctor records the change in patient’s blood pressure from 125 mmHg to 135 mmHg over 2 hours. Calculate the gradient of the blood pressure increase.
