Specimen Collection And Testing Quiz!

When collecting a specimen, it is important to wash your hands both before and after the procedure. Washing your hands before ensures that you have clean hands to prevent any potential contamination of the specimen. Washing your hands after helps to remove any potential pathogens or contaminants that may have been acquired during the collection process. By washing your hands both before and after, you can minimize the risk of cross-contamination and maintain proper hygiene standards.

The information that must be put on the specimen label includes the type of specimen, client's name and address, and the date and time. All of these details are important for proper identification and tracking of the specimen. The type of specimen helps in determining the appropriate tests to be conducted, while the client's name and address ensure that the results are correctly associated with the right individual. The date and time provide a record of when the specimen was collected, which is crucial for monitoring any changes or trends over time.

The correct answer is "Right specimen, time, amount, and container." When collecting specimens, it is important to ensure that the right specimen is collected to accurately diagnose and treat the patient. The time at which the specimen is collected is also crucial as certain tests may require specific timing. The amount of the specimen collected should be sufficient for testing purposes. Lastly, the container used to collect the specimen should be appropriate to maintain its integrity and prevent contamination.

A sputum specimen is collected to determine problems in the respiratory or pulmonary system. Sputum is the mucus that is coughed up from the lower respiratory tract. By analyzing the sputum, healthcare professionals can identify any abnormalities or infections in the respiratory system, such as pneumonia, tuberculosis, or chronic obstructive pulmonary disease (COPD). Therefore, the correct answer is respiratory or pulmonary.

Gloves should be put on before touching bedpan, patient, or specimen to prevent the transmission of any potential pathogens or contaminants between the healthcare worker and the patient or specimen. This helps to maintain hygiene and reduce the risk of infection.

The best time to collect a sputum specimen is first thing in the morning. This is because during the night, mucus and secretions accumulate in the airways, making it easier to produce a sputum sample. Additionally, the sputum collected in the morning is less likely to be contaminated with food particles from meals, providing a more accurate sample for analysis.

The urine for a 24-hour specimen must be stored in a refrigerator or on ice. This is because refrigeration or keeping the urine on ice helps to preserve the integrity of the specimen and prevent bacterial growth. Storing the urine at a low temperature also helps to slow down any chemical reactions that may occur, ensuring that the sample remains stable and accurate for further analysis.

A midstream clean catch urine specimen refers to the process of cleaning the genital area before collecting a urine sample. The area is cleaned off to remove any contaminants, and then a small amount of urine is voided before collecting the specimen. This helps to ensure that the sample collected is free from any external contaminants and is a more accurate representation of the urine composition.

Collecting urine from an indwelling Foley catheter can lead to a major potential problem of urinary infection from contamination. This is because indwelling Foley catheters are prone to bacterial colonization, which can result in urinary tract infections. The presence of the catheter increases the risk of introducing bacteria into the urinary system, leading to infection. Therefore, collecting urine from an indwelling Foley catheter can increase the chances of contamination and subsequent urinary infection.

A stool that is black in color might indicate the presence of blood or iron. The dark color of the stool is typically caused by the oxidation of blood in the gastrointestinal tract. This can occur due to bleeding in the upper digestive system, such as from ulcers or tumors, or from the consumption of iron-rich foods or supplements. Therefore, the presence of blood or iron can be inferred from the black color of the stool.

The urine collected at 7 a.m. on the first day is discarded because it represents the first voiding of the day, which may contain residual urine from the previous night. To ensure accurate results, the collection of a 24-hour urine specimen typically starts with discarding the first void and collecting all subsequent urine for the next 24 hours.

The urine collected at 7 a.m. on the last day is saved when collecting a 24-hour urine specimen. This is because a 24-hour urine collection requires collecting all urine produced over a 24-hour period, including the urine collected at 7 a.m. on the last day. Saving this urine is important to ensure an accurate measurement of various substances in the urine, such as creatinine or protein, which may be used for diagnostic purposes.

The correct answer is 1-2 tbsp. This is the appropriate amount of stool needed for a specimen.

In general, specimens for determining the concentration of body constituents should be collected when the patient is in a basal state (ie, in the early morning after awakening and about 12 to 14 hours after the last ingestion of food).
