b. if the blood glucose meter has been dropped and or to check performance of the system.

c. if the test strip container was left open or exposed to extreme cold, heat, or humidity.

e. when test results contradict clinical symptoms or anytime questionable results are obtained.

f. all of the above.

Explanation:

To determine the correct answer, we analyze each option:

• Option a: Daily quality control before patient testing is a standard practice to ensure meter accuracy.
• Option b: Dropping the meter or checking system performance requires quality control to verify accuracy.
• Option c: Test strip exposure to extreme conditions can affect results, so quality control is needed.
• Option d: Opening a new box of test strips may introduce variability, so quality control is appropriate.
• Option e: Contradictory or questionable results warrant quality control to check the meter.

Since all these situations (a - e) require running quality controls, the correct option is f.

Answer:

f. All of the above.
