The first drop of blood should be wiped away during a dermal puncture to remove any potential contaminants from the skin surface, such as tissue fluid, dirt, or debris. This helps ensure that the sample collected is representative of the blood and not influenced by external factors. Additionally, wiping away the first drop can help minimize the risk of hemolysis or skewed results caused by interstitial fluid.

Which fingers should be used for dermal puncture to obtain capillary blood specimens?
For dermal puncture to obtain capillary blood specimens, the recommended fingers are typically the middle or ring finger of the non-dominant hand. These fingers have adequate blood supply and are less likely to be calloused compared to the index finger. The puncture should be made on the side of the fingertip to minimize discomfort and maximize blood flow. In infants, the heel is often used for this procedure.
What happens when you warm the site of a dermal puncture?
Increases blood flow to the site
Is there another name for dermal puncture?
capillary blood collection
What is dermal puncture?
Dermal puncture refers to a technique used to obtain capillary blood samples by pricking the skin using a lancet or needle. It is commonly done on the finger, heel, or other suitable site for blood collection in medical settings such as hospitals, clinics, or laboratories.
List a test that is taken from a dermal puncture and explain why this preferred over a venipuncture?
One example of a test taken from a dermal puncture is a blood glucose test. Dermal punctures are preferred for this test as they are less invasive, cause minimal discomfort, and can be easily performed on individuals with difficult-to-access veins such as infants or elderly patients.
When it is best to perform a dermal puncture rather than a venipuncture on children?
A dermal puncture is preferred over a venipuncture in young children, especially infants, when obtaining small blood samples is necessary, such as for blood glucose monitoring or when only a few drops of blood are required. It minimizes discomfort and reduces the risk of complications associated with larger needles and venous access. Additionally, dermal punctures are often more convenient and can be performed quickly at the point of care.
Skin puncture blood most closely resembles what kind of fluid?
Skin puncture blood most closely resembles venous blood, which is the blood collected from veins for laboratory tests. However, it may contain some interstitial fluid due to the puncture of capillaries in the skin during the collection process.
When collecting blood from a dermal puncture which test should be colleted first?
Order of Draw: Yellow (SSP) Light Blue Red Gold/Tiger Top Light Green/Tiger Green Dark Green Lavender Pink White Gray Yellow (ACD) Dark Blue
How do you detect arterial puncture and if it happens what should you do?
I assume the 'puncture' is accidental. An arterial puncture is characterized by bright red blood (as opposed to darker venous blood). Arterial cuts bleed fast and forceful, often in time with the heartbeat. If that happens, get thee to an emergency room-quick!
Should there be blood in my IV line?
No, there should not be blood in your IV line. If you see blood in the IV line, it may indicate a problem such as a dislodged catheter or vein puncture, and you should notify your healthcare provider immediately.
Is 2 percent the dermal blood vessels in your body?
no
Is blood drawn from veins or arteries during a medical procedure?
Blood is typically drawn from veins during a medical procedure, as veins are more accessible and less risky to puncture compared to arteries.
