A phlebotomist is preparing to collect a capillary blood specimen from a patient using the aseptic technique. Which of the following cleansing agents should the phlebotomist use?
Povidone-iodine
Hand sanitizer
70% isopropyl alcohol
10% chlorine bleach solution
The Correct Answer is C
Choice A Reason:
Povidone-iodine is an antiseptic used for skin disinfection before and after surgery. It has a broad spectrum of antimicrobial activity, but it is not the preferred choice for capillary blood collection due to the potential interference with certain laboratory tests. Povidone-iodine needs to be completely dried to avoid hemolysis of the sample, which can affect test results.
Choice B Reason:
Hand sanitizer is generally used for hand hygiene and not for the disinfection of the site for blood specimen collection. While it is effective in killing germs on the skin, it contains emollients and gelling agents that can contaminate the blood sample and interfere with laboratory tests.
Choice C Reason:
70% isopropyl alcohol is the most commonly used disinfectant for aseptic technique in capillary blood collection. It is effective against a broad range of microorganisms and evaporates quickly, leaving no residue that could contaminate the sample. It is important to allow the alcohol to dry completely before performing the puncture to prevent stinging and sample dilution.
Choice D Reason:
A 10% chlorine bleach solution is not typically used for skin disinfection in blood collection due to its harshness and potential to cause skin irritation and damage. It is more commonly used for disinfecting surfaces and equipment in healthcare settings.

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:
Notifying the provider about the error is an important step, but it does not correct the error in the patient's chart. Communication with the provider ensures that they are aware of the mistake and can make informed decisions regarding patient care. However, the physical correction of the documentation is also necessary to maintain accurate medical records.
Choice B Reason:
Asking an administrator to erase the error is not a recommended practice. Erasing or using correction fluid can make the chart appear tampered with, which can have legal implications. It is essential that the original entry remains visible to preserve the integrity of the medical record.
Choice C Reason:
Striking a line through the error and initialing is the correct method for correcting a written error in a patient's chart¹². This approach allows the original entry to remain legible, which is crucial for legal and clinical reasons. It also shows that the correction was made by an authorized individual, as the initials indicate who made the change.
Choice D Reason:
Erasing the error and entering the correct information is not an acceptable practice for the same reasons as choice B. It is important not to remove or conceal the original entry, as this could be considered falsifying medical records.
