Where do you place tourniquet on geriatric patient?

Back

For geriatric blood draws, place it 1-2 inches above the chosen vein or use a blood pressure cuff at a lower pressure, ensuring it's not overly tight and removed within one minute to prevent bruising and vein collapse.

Lactic acid test

Back

A lactic acid test measures the level of lactic acid in the blood. Lactic acid is a byproduct of muscle metabolism that accumulates when there is not enough oxygen in the body's tissues.

What do you do when drawing ABG?

Back

An ABG test procedure involves puncturing an artery, most commonly the radial artery in the wrist, to collect a blood sample for analysis. The procedure includes performing an Allen's test to ensure adequate circulation to the hand, sterilizing the site, inserting a heparinized syringe to collect a sample, and then applying firm pressure to the puncture site for several minutes to stop any bleeding.

What should you do if you hear hiss sound during venipuncture?

Back

f you hear a hissing sound during venipuncture, stop the procedure, slightly withdraw and/or reposition the needle, as the hiss indicates air is being sucked in because the vein wasn't fully entered or was missed. If adjusting doesn't work, remove the needle, address the puncture site, and consider a new site to avoid further complications.
