1.
List the four rules when collecting specimens:
Correct Answer
A. Right specimen, time, amount and container
Explanation
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.
2.
When collecting a specimen, when should you wash your hands?
Correct Answer
B. Before and after
Explanation
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.
3.
When should you put on gloves?
Correct Answer
B. Before touching bedpan, patient, or specimen
Explanation
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.
4.
What information must be put on the specimen label?
Correct Answer
D. All of the above
Explanation
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.
5.
A routine specimen should be collected:
Correct Answer
B. When the patient is in basal state
Explanation
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).
6.
When collecting a 24-hour urine specimen:
What is done with the urine collected at 7 a.m. on the first day?
Correct Answer
B. Discard
Explanation
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.
7.
When collecting a 24-hour urine specimen:
What is done with the urine collected at 7 a.m. on the last day?
Correct Answer
A. Saved
Explanation
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.
8.
When collecting a 24-hour urine specimen:
Where must the urine for a 24-hour specimen be stored?
Correct Answer
D. Refrigerator or on ice
Explanation
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.
9.
When collecting a 24-hour urine specimen:
What is a midstream clean catch urine specimen?
Correct Answer
B. Area is cleaned off and specimen is saved after a small amount has been voided
Explanation
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.
10.
When collecting a 24-hour urine specimen:
What is a major potential problem with collecting urine from an indwelling Foley catheter?
Correct Answer
A. Urinary infection from contamination
Explanation
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.
11.
The amount of stool needed for a specimen is ________________.
Correct Answer
C. 1-2 tbsp.
Explanation
The correct answer is 1-2 tbsp. This is the appropriate amount of stool needed for a specimen.
12.
A stool that is black in color might indicate the presence of _____________ or ____________.
Correct Answer
C. Blood or Iron
Explanation
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.
13.
The best time to collect a sputum specimen is __________________.
Correct Answer
A. First thing in morning
Explanation
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.
14.
A sputum specimen is collected to determine problems in the ___________system.
Correct Answer
C. Respiratory or pulmonary
Explanation
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.
