Drawing more than the recommended amount of an infant's blood volume may result in which of the following conditions?

Choice A Reason:
Disposing of contaminated materials is a part of standard infection control practices. While it is important to dispose of materials that may be contaminated with blood or bodily fluids properly, this action is not specific to the aseptic technique used during venipuncture.

Choice B Reason:
Performing hand hygiene once daily is not sufficient for maintaining aseptic technique. Aseptic technique requires hand hygiene before and after each patient contact, especially before procedures like venipuncture to prevent the transmission of pathogens.

Choice C Reason:
Completing quality control procedures is an essential part of laboratory practice and patient safety but is not directly related to the aseptic technique of venipuncture. Quality control ensures the accuracy and reliability of test results rather than preventing infection.

Choice D Reason:
Cleansing the skin with sodium hypochlorite, or a similar disinfectant, is a critical step in aseptic technique for venipuncture. This action reduces the microbial load on the skin, thereby minimizing the risk of introducing pathogens into the bloodstream during needle insertion.

Choice A Reason:
Warfarin does not typically require a fasting state before blood is drawn for testing. The medication's effect on clotting factors is independent of food intake. Therefore, a fasting requirement is not anticipated for patients taking warfarin unless specified for other concurrent tests.

Choice B Reason:
There is no need for an alternate antiseptic due to warfarin use. Standard antiseptic procedures are sufficient when drawing blood from patients on warfarin. The choice of antiseptic would be more influenced by patient allergies or specific institutional protocols.

Choice C Reason:
Patients on warfarin have an increased bleeding time because the medication is an anticoagulant, which means it works to prevent blood clots by thinning the blood. This can lead to prolonged bleeding after a venipuncture, and phlebotomists should be prepared to apply pressure for a longer time to ensure hemostasis.

Choice D Reason:
Placing a specimen on ice is not a standard procedure for blood samples taken for warfarin monitoring, which is typically done through a PT/INR test. This test measures the time it takes for blood to clot and is not affected by temperature in the same way that tests for certain enzymes or gases might be.
