A phlebotomist is performing a venipuncture on a patient who is allergic to alcohol. Which of the following is an appropriate antiseptic to use in place of alcohol?
Sterile water
Antiseptic foam
Chlorhexidine
Saline
The Correct Answer is C
Choice A Reason:
Sterile water is not an antiseptic; it does not contain antimicrobial agents. While it can be used to rinse a site, it will not disinfect the area before a venipuncture procedure. Therefore, it is not an appropriate substitute for alcohol in this context.
Choice B Reason:
Antiseptic foam may contain alcohol or other disinfectants. If it is alcohol-free, it could be a suitable alternative. However, without specific information about the ingredients, it cannot be assumed to be an appropriate choice for a patient allergic to alcohol.
Choice C Reason:
Chlorhexidine is a commonly used antiseptic for skin preparation before medical procedures, including venipuncture. It is effective against a broad spectrum of bacteria and is an appropriate alternative for patients who have an allergy to alcohol-based antiseptics.
Choice D Reason:
Saline solution is not an antiseptic. It is a sterile solution of sodium chloride in water and does not have antimicrobial properties. Like sterile water, it is not suitable for disinfecting the venipuncture site.

Correct Answer is B
Explanation
Choice A Reason:
Positioning the needle at a 45° angle to the skin is not the recommended approach for venipuncture using a butterfly needle on dorsal hand veins. The correct angle for insertion is usually less than 45°, often around 15-30°, to ensure a shallow entry and reduce the risk of going through the vein.
Choice B Reason:
Holding the needle by the wings of the butterfly is the correct technique. This allows for better control and stability during insertion. The wings are designed to be held between the thumb and forefinger, providing an easy grip for the phlebotomist to maneuver the needle with precision.
Choice C Reason:
Instructing the patient to hold the collection tubes is not standard practice and could lead to pre-analytical errors. The phlebotomist should maintain control of the tubes to ensure proper blood flow and fill volume, as well as to prevent contamination or accidents.
Choice D Reason:
Applying the tourniquet at the antecubital area is not specific to the use of a butterfly needle for venipuncture on dorsal hand veins. While a tourniquet is used to engorge the veins and make them more prominent, its placement may vary depending on the selected puncture site and is not the action in question here.
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.
