Which of the following refers to the process of cleaning up a blood specimen spill on a counter?

Choice A Reason:
Encouraging the patient to chew gum during the procedure may serve as a distraction, which can be helpful for some patients. However, this is not a widely recommended practice for reducing needle phobia. Distraction techniques can be beneficial, but they should be tailored to the individual patient's preferences and should not interfere with the procedure.

Choice B Reason:
Instructing the patient to lie supine during the procedure can help prevent fainting and reduce anxiety for some patients. This position is often used for patients who have a history of fainting or feel dizzy during blood draws. However, it is not specifically targeted at managing needle phobia.

Choice C Reason:
Placing the patient's elbow joint at 90 degrees of flexion is a standard practice to stabilize the arm and provide an optimal angle for venipuncture. While this is a necessary step in the procedure, it does not directly address the patient's needle phobia.

Choice D Reason:
Warming the site for 10 minutes before venipuncture is a technique used to enhance vein visibility and elasticity, making the venipuncture easier and potentially less painful. This can be particularly helpful for patients with needle phobia, as a smoother and quicker procedure may reduce anxiety and discomfort.

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.
