A phlebotomist is preparing to perform a venipuncture. Which of the following needle positions should the phlebotomist use?
Bevel down at a 30° angle
Bevel up at a 45° angle
Bevel up at a 30° angle
Bevel down at a 45° angle
The Correct Answer is C
Choice A reason:
Having the bevel down at a 30° angle is not the correct needle position for venipuncture. The bevel of the needle should be facing up to allow for a smoother insertion and to minimize the risk of damaging the vein or causing discomfort to the patient.
Choice B reason:
Positioning the bevel up at a 45° angle is not recommended for venipuncture as this angle is too steep and could lead to the needle penetrating through the vein, potentially causing a hematoma or other complications.
Choice C reason:
The bevel up at a 30° angle is the correct position for venipuncture. This position allows the phlebotomist to insert the needle with the bevel facing upwards, which is the sharpest part of the needle, ensuring a clean entry into the vein. The 30° angle is shallow enough to enter the vein without going through it and causing injury.
Choice D reason:
A bevel down at a 45° angle is incorrect for the same reasons as choice B. Additionally, with the bevel down, the non-beveled side, which is duller, would make the initial contact with the skin, potentially causing more pain and making it more difficult to penetrate the vein.

Correct Answer is D
Explanation
Choice A reason:
Collecting stool directly into a sterile container is not related to providing a sputum specimen. Stool samples are collected for different types of tests, such as fecal occult blood tests or microbiological cultures, and are not used for respiratory assessments.
Choice B reason:
Discarding the first urine of the day and collecting for 24 hours is a procedure for a 24-hour urine collection test, which is used to assess kidney function and other conditions. This process is unrelated to sputum specimen collection, which is used to evaluate respiratory infections or conditions.
Choice C reason:
Aggressively swabbing the inside of the cheek is a method used to collect cells for DNA testing or to check for oral infections. This action does not pertain to sputum collection, which requires a sample from the lower respiratory tract.
Choice D reason:
Taking a deep breath and then expectorating (coughing up and spitting out) is the correct method for providing a sputum specimen. This technique ensures that the sputum comes from deep within the lungs, which is necessary for accurate analysis of respiratory pathogens or cells.
Correct Answer is C
Explanation
Choice A reason:
While ensuring that employees receive training regarding workplace hazards is important, it is not the general concept behind standard precautions. Training is a part of the broader safety measures but does not encompass the core idea of standard precautions, which is to prevent infection transmission.
Choice B reason:
Providing information about hazardous chemicals within the environment is related to the Right-to-Know standard, which is part of the Hazard Communication Standard. This is not the main concept of standard precautions, which focus on preventing the spread of infections, particularly in healthcare settings.
Choice C reason:
Assuming that all body fluids are potentially infected with bloodborne pathogens is the essence of standard precautions. This approach dictates that healthcare workers should treat all body fluids as if they are infectious and therefore use appropriate protective measures to prevent exposure and transmission of diseases.
Choice D reason:
Maintaining a workplace free of environmental hazards is a broad occupational safety goal but does not specifically describe the general concept behind standard precautions. Standard precautions are more focused on infection control practices rather than the broader scope of all environmental hazards.
