What is the primary reason a tourniquet should not be left on a patient's arm for more than one minute?

PPE stands for Personal Protective Equipment and includes gloves, gowns, masks, and eye protection used to prevent exposure to infectious agents.
Which condition causes a patient's veins to be difficult to locate and may require a butterfly needle on a hand vein?

What is 'iatrogenic anemia' in the context of phlebotomy?
Answer: Anemia induced by excessive blood draws by healthcare providers
Iatrogenic anemia refers to anemia caused by repeated or excessive blood draws by medical staff, a recognized concern especially in ICU patients.
Which term describes a collapsed vein during venipuncture when vacuum draw pressure is too high?
Answer: Vein collapse
Vein collapse occurs when the vacuum pressure of an evacuated tube exceeds the pressure inside a fragile or small vein, cutting off blood flow.
Which blood culture collection technique is critical to prevent contamination?
Answer: Scrubbing the venipuncture site with 70% isopropyl alcohol followed by chlorhexidine or povidone-iodine
Blood cultures require a two-step antiseptic technique—alcohol followed by chlorhexidine or povidone-iodine—to minimize false-positive results from skin flora contamination.
