A medical assistant is preparing a patient for a colonoscopy. Which of the following should the assistant obtain from the patient prior to the procedure?

Correct answer: C
A. Taking aspirin within 12 hr of testing: Aspirin does not generally impact spirometry results.
B. Using sedatives within 1 hr of testing: While sedatives might affect breathing, they are not commonly noted as a significant factor for spirometry test preparation.
C. Exercising 2 hr prior to testing: Exercise can temporarily affect lung function, so it's advised to avoid vigorous exercise before a spirometry test to ensure accurate results.
D. Eating a heavy meal 4 hr prior to testing: Although a heavy meal might cause some discomfort, it is less likely to affect the spirometry results compared to exercise.

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.
