While collecting a blood sample, the patient slumps over in the phlebotomy chair. Which of the following actions should the phlebotomist take first?
A. Stop the procedure.
Stopping the procedure is the first and most critical action a phlebotomist should take if a patient slumps over during blood collection. The patient's safety is the primary concern, and continuing the procedure could cause further harm. The phlebotomist should immediately remove any needles or equipment from the patient to prevent injury.
B. Alert the supervisor.
Alerting the supervisor is an important step, but it should come after ensuring the patient is safe and the procedure has been stopped. The supervisor will need to be informed of the incident to help manage the situation and provide assistance as needed.
C. Document the incident.
Documenting the incident is a necessary step for legal and medical records. However, it is not the first action to take. The patient's immediate well-being takes precedence over documentation, which can be completed after the situation is under control and the patient is stable.
D. Slide the patient to the floor.
Sliding the patient to the floor may be necessary if the patient is at risk of falling from the chair. However, this should only be done after the procedure has been stopped, and if it is safe to move the patient. If the patient is unconscious, the phlebotomist may need to initiate CPR, which is best performed on a flat surface.

Similar Questions
Which of the following types of tests is a phlebotomist allowed to perform according to CLIA regulations?
A. Occult blood detection
Occult blood detection is a test that a phlebotomist is allowed to perform according to CLIA regulations. This test is typically used to detect hidden blood in the stool, which can be an early sign of colorectal cancer or other digestive system diseases. It is considered a waived test under CLIA, meaning it is simple and carries a low risk for an incorrect result.
B. Flow cytometry
Flow cytometry is a complex test that requires specialized training and equipment. It is used to analyze the physical and chemical characteristics of particles in a fluid as they pass through at least one laser. Phlebotomists are not typically trained to perform this type of analysis, as it falls under the category of high complexity testing.
C. Genetic molecular
Genetic molecular tests are used to detect specific sequences in DNA or RNA that may or may not lead to disease. These tests are complex and require specialized knowledge and equipment. They are not within the scope of practice for phlebotomists, who are trained primarily in blood collection.
D. Electrophoresis
Electrophoresis is a laboratory technique used to separate DNA, RNA, or protein molecules based on their size and electrical charge. This type of test is also complex and requires specialized training and equipment, which is beyond the scope of a phlebotomist's duties.

When calculating total blood volume for a full-term, 2-day-old infant, which of the following information should a phlebotomist consider?
A. Apgar score
The Apgar score is a quick test performed on a newborn at 1 and 5 minutes after birth. The 1-minute score determines how well the baby tolerated the birthing process. The 5-minute score tells the healthcare provider how well the baby is doing outside the mother's womb. While it is an important indicator of a newborn's health, it does not directly influence the calculation of total blood volume.
B. Height
Height is a measure of the length of a person's body. In the context of a 2-day-old infant, height is not a practical or necessary measurement for determining blood volume. Blood volume is more closely related to weight than to height, especially in the case of infants.
C. Head circumference
Head circumference is a measurement of the size of a child's head and is used to monitor brain growth. While it can provide valuable information about a child's development, it is not used to calculate blood volume. The total blood volume of an infant is not determined by the size of the head but rather by the overall weight.
D. Weight
Weight is the correct factor to consider when calculating total blood volume for a full-term, 2-day-old infant. The standard formula to estimate an infant's total blood volume is approximately 80 {mL/kg} of body weight. Therefore, knowing the infant's weight in kilograms is essential for this calculation.

When a phlebotomist's hands are visibly soiled with blood or body fluids, which of the following decontamination agents should the phlebotomist use to clean them?
A. Alcohol-based hand rub
An alcohol-based hand rub is generally used for hand hygiene when the hands are not visibly soiled. It is effective against many types of microbes but is not the best option for hands that are visibly dirty or contaminated with proteinaceous materials, such as blood or body fluids. The CDC recommends washing hands with soap and water in these situations.
B. Sterile water rinse
Sterile water rinse alone is not sufficient for cleaning hands that are visibly soiled. While sterile water can be used to rinse off debris, it does not have the cleaning or antimicrobial properties necessary to properly decontaminate the hands.
C. Soap and water
Soap and water are the recommended decontamination agents when hands are visibly soiled with blood or body fluids. The physical action of handwashing, combined with the detergent properties of soap, effectively removes soil and transient microorganisms. The CDC guidelines specifically state that hands should be washed with soap and water when they are visibly dirty or contaminated with proteinaceous materia.
D. Alcohol rinse
An alcohol rinse, similar to an alcohol-based hand rub, is not adequate for cleaning visibly soiled hands. Alcohol is a disinfectant that is effective against many germs when used on clean hands but does not remove visible dirt or organic material well.
