Which of the following is the size of the border around the edge of a Mayo tray that is considered contaminated in a sterile field?
1/4 inch
1/2 inch
1 inch
1 1/2 inches
The Correct Answer is C
A. 1/4 inch: A 1/4 inch border is too small to be considered a standard contaminated area. The correct border size is larger.
B. 1/2 inch: A 1/2 inch border is also not standard; the correct contaminated border is larger.
C. 1 inch: The standard for sterile fields is to consider a 1-inch border around the edge of the sterile field as contaminated. This helps to prevent inadvertent contamination of sterile items.
D. 1 1/2 inches: A 1 1/2 inch border is unnecessarily large and exceeds the standard 1-inch margin considered contaminated.

Correct Answer is B
Explanation
A. Instruct the patient to collect the specimen and return it to the laboratory: For a valid drug screening, the specimen should be collected in the presence of a medical professional to prevent tampering.
B. Measure and record the temperature of the specimen: Measuring and recording the temperature of the urine specimen is important to ensure that the sample is fresh and has not been tampered with or substituted.
C. Pre-label the specimen container prior to collection: The container should be labeled after the specimen is collected to avoid mix-ups and to ensure accurate tracking.
D. Have the patient begin collecting the specimen mid-stream: The specimen for drug testing should typically be collected as a first-morning or a mid-stream sample to ensure accuracy, but this can vary based on specific protocols.
Correct Answer is B
Explanation
A. Implied consent: Implied consent is typically used in emergency situations where verbal or written consent cannot be obtained and is not suitable for elective procedures like a colonoscopy.
B. Informed consent: For a colonoscopy, which is an invasive procedure, informed consent is required. This involves providing the patient with detailed information about the procedure, its risks, benefits, and alternatives.
C. Prior authorization: Prior authorization is related to insurance coverage and is not typically obtained by the medical assistant; it is usually handled by the billing department or insurance coordinator.
D. Immunization records: Immunization records are not required for a colonoscopy; they are more relevant for vaccinations and certain other procedures.
