Common Quiz Questions and Answers

Many quizzes focus on the operation, maintenance, and troubleshooting of the Nova StatStrip Glucose Meter. Here are some common questions you might encounter, along with detailed answers and explanations:

Question 1: What type of sample can be used with the Nova StatStrip Glucose Meter?

Answer: The Nova StatStrip Glucose Meter is designed to use capillary, venous, or arterial whole blood samples. This flexibility allows healthcare providers to choose the most appropriate sampling method based on the patient's condition and clinical setting.

Explanation: Using whole blood is crucial because the meter is calibrated specifically for this type of sample. Plasma or serum samples, which are sometimes used in laboratory settings, are not appropriate for the StatStrip meter and can lead to inaccurate results.

Question 2: What is the measuring range of the Nova StatStrip Glucose Meter?

Answer: The measuring range is typically 10 to 600 mg/dL (0.6 to 33.3 mmol/L).

Explanation: This wide range allows the meter to accurately measure glucose levels in patients with both hypoglycemia (low blood sugar) and hyperglycemia (high blood sugar). It’s important to be aware of this range to interpret results correctly and take appropriate clinical action.

Question 3: How often should quality control (QC) testing be performed on the Nova StatStrip Glucose Meter?

Answer: Quality control testing should be performed according to the facility's policies and procedures, but generally:

• At least once per day.
• With each new lot of test strips.
• Whenever the meter is dropped or damaged.
• If results seem questionable.

Explanation: QC testing ensures that the meter is functioning correctly and providing accurate results. It involves running control solutions with known glucose concentrations and comparing the meter readings to the expected values. Regular QC testing helps to identify and correct any issues with the meter or test strips.

Question 4: What type of technology does the Nova StatStrip Glucose Meter use to measure glucose?

Answer: The Nova StatStrip uses electrochemical biosensor technology.

Explanation: This technology involves a chemical reaction between glucose in the blood sample and specific enzymes on the test strip. The reaction generates an electrical current that is proportional to the glucose concentration. The meter measures this current and converts it into a glucose reading.

Question 5: What should you do if you get an error code on the Nova StatStrip Glucose Meter?

Answer: The appropriate action depends on the specific error code, but generally you should:

1. Consult the meter's user manual for the meaning of the error code.
2. Troubleshoot the issue based on the manual's recommendations (e.g., reinsert the test strip, check the sample volume).
3. If the error persists, contact the appropriate support personnel (e.g., point-of-care coordinator, biomedical engineering).

Explanation: Error codes indicate that something is preventing the meter from functioning correctly. It’s important to address these errors promptly to avoid inaccurate results. The user manual is the best resource for understanding and resolving error codes.

Question 6: How do you clean the Nova StatStrip Glucose Meter?

Answer: To clean the meter:

1. Turn off the meter.
2. Use a soft, lint-free cloth slightly dampened with a mild disinfectant solution recommended by the manufacturer.
3. Gently wipe the exterior surfaces of the meter.
4. Avoid getting moisture in the test strip port or other openings.
5. Allow the meter to air dry completely before use.

Explanation: Proper cleaning and disinfection are essential to prevent the spread of infection. Always follow the manufacturer's recommendations for cleaning solutions and procedures.

Question 7: What are some common interferences that can affect the accuracy of the Nova StatStrip Glucose Meter?

Answer: While the StatStrip is designed to minimize interferences, some substances can still affect accuracy, including:

• Hematocrit: Extremely high or low hematocrit levels can interfere with glucose readings.
• Ascorbic Acid (Vitamin C): High concentrations of ascorbic acid can lead to falsely elevated glucose readings.
• Uric Acid: Elevated uric acid levels may also cause interference.
• Paracetamol (Acetaminophen): In some cases, high doses of paracetamol can affect glucose results.

Explanation: Understanding potential interferences is crucial for interpreting glucose results accurately, especially in patients with complex medical conditions. If interference is suspected, it may be necessary to confirm the result with a laboratory test.

Question 8: How is the Nova StatStrip Glucose Meter connected to the hospital information system (HIS)?

Answer: The Nova StatStrip can be connected to the HIS through wired or wireless network connections.

Explanation: Connectivity allows for seamless transmission of glucose results to the patient's electronic medical record (EMR). This improves efficiency, reduces the risk of transcription errors, and facilitates timely clinical decision-making.

Question 9: What are the storage requirements for Nova StatStrip test strips?

Answer: Test strips should be stored:

• In their original, unopened container.
• At room temperature, as specified by the manufacturer (typically 15-30°C or 59-86°F).
• Away from direct sunlight and moisture.

Explanation: Improper storage can damage the test strips and lead to inaccurate results. Always check the expiration date before use and discard any expired or damaged strips.

Question 10: What type of data management software is compatible with the Nova StatStrip Glucose Meter?

Answer: The Nova StatStrip is compatible with NovaNet data management software.

Explanation: NovaNet is a software system designed to manage and analyze data from Nova Biomedical point-of-care devices. It provides features for quality control, operator management, and data reporting.
