A phlebotomist should recognize that proper hand hygiene can result in which of the following?
A decrease in the incidence of health care-associated infections
An increase in the accuracy of laboratory results
A decrease in the rejection of laboratory specimens
An increase in the potential sources of pathogens
The Correct Answer is A
Choice A Reason:
Proper hand hygiene is one of the most effective measures to prevent the spread of infections within health care settings. By thoroughly cleaning hands, phlebotomists and other health care workers can significantly reduce the transmission of pathogens that can lead to health care-associated infections (HAIs). These infections are a major cause of morbidity and mortality among hospitalized patients and can be prevented by adhering to strict hand hygiene protocols.
Choice B Reason:
While hand hygiene is crucial for preventing contamination and infection, it does not directly increase the accuracy of laboratory results. The accuracy of laboratory results is more dependent on the proper collection, handling, and processing of specimens, as well as the precision of the testing equipment and methodologies used.
Choice C Reason:
Good hand hygiene can help decrease the rejection of laboratory specimens by preventing contamination. Contaminated specimens can lead to inaccurate results and may need to be recollected, which is inconvenient for the patient and can delay diagnosis and treatment. However, the primary outcome of proper hand hygiene is the prevention of HAIs, rather than the reduction of specimen rejection.
Choice D Reason:
Proper hand hygiene leads to a decrease, not an increase, in the potential sources of pathogens. By effectively removing germs from the hands, the risk of transmitting infectious agents is minimized. This is essential in a health care setting where patients may be vulnerable to infections due to weakened immune systems or open wounds.

Correct Answer is C
Explanation
Choice A reason:
A 16-gauge needle is quite large and is typically used for rapid fluid administration or blood donation in adults. It is not suitable for pediatric patients due to the size of their veins and the potential for causing trauma and discomfort.
Choice B reason:
An 18-gauge needle is also large and commonly used for adult patients in situations where larger volumes of blood are needed quickly. For a 6-year-old patient, this gauge would be too large and could cause significant pain and increase the risk of damaging the vein.
Choice C reason:
A 23-gauge needle is recommended for pediatric patients, including those who are 6 years old. It is small enough to minimize discomfort and the risk of injuring the vein, yet it allows for adequate blood flow for collection³. This size needle is often used with a winged infusion set, which is suitable for the smaller, more fragile veins of pediatric patients.
Choice D reason:
A 27-gauge needle is very small and is typically used for intradermal injections or for very small veins, such as those in neonates. While it would cause minimal discomfort, it may not provide an adequate flow rate for venipuncture in a 6-year-old patient.
Correct Answer is C
Explanation
Choice A reason:
The laboratory accession number is a unique identifier assigned to a patient's specimen once it is received by the laboratory. While it is an important piece of information, it is not provided by the physician's office to the phlebotomist for specimen collection. Instead, it is generated by the laboratory after the specimen is collected and submitted for analysis.
Choice B reason:
The Physician's NPI (National Provider Identifier) number is a unique identification number for covered health care providers in the United States. While it is used for billing and identification purposes, it is not the information that the physician's office needs to provide to a phlebotomist for the purpose of specimen collection.
Choice C reason:
The laboratory requisition form is the correct document that should be provided by the physician's office. This form contains the patient's demographic information, the tests ordered by the physician, special instructions for specimen collection, and any other pertinent information required for proper specimen handling and testing.
Choice D reason:
The physician's encounter form typically contains details of the patient's visit, including services provided, diagnoses, and billing information. It is not specifically used for laboratory specimen collection and therefore is not the information that should be provided to a phlebotomist for this purpose.
