The following statements are all false. Circle the one or two words that make the statement false and write the correct word(s) that would make the statement true in the space provided.
1. The modified Allen test checks for the presence of collateral circulation to the hand via the RADIAL artery.
2. Arterial puncture is typically LESS painful than venipuncture.
3. COLOR is, in fact, a reliable indicator of successful arterial puncture.
PUMP?* not sure
4. The proper angle of needle insertion for femoral artery puncture is -45- degrees.
5. STEADY STATE for ABG collection, means the patient has had no food.
6. Specimens for electrolyte testing in addition to arterial blood gas (ABG) analysis should be transported ON ICE.
7. After performing arterial puncture, the RESPIRATION is checked distal to ensure no damage has occurred during the draw.
8. Injury to the intima, or inner wall of the artery, can lead to a HEMATOMA.
9. PHLEBITIS is a complication associated with arterial puncture.
The femoral artery is the SECOND choice for arterial puncture for ABGs.
List eight hazards or complications of arterial puncture.
2. Artery damage
7. Thrombus formation
8. Vasovagal response
List seven sampling errors associated with ABG collection.
1. Air bubbles
2. Delay in analysis
3. Improper mixing
4. Improper syringe
5. Obtaining venous blood by mistake
6. Use of improper anticoagulant
7. Use of too much or too little heparin
List eight criteria for specimen rejection and state how you wold prevent such a rejection from happening.
1. Air bubbles in the specimen
1. Securing the attachment of the needle to the syringe can help minimize air bubbles.
2. Clotted specimen
2. Make sure to properly mix the sample after collection; also be sure to use heparin syringe.
3. Hemolysis of the specimen
3. Make sure not to pull too fast on the syringe; make sure that it is filled up slowly.
4. Improper or absent ID or other labeling requirements
4. Make sure to appropriately label the sample before leaving the patient.
5. Improper transportation temperature
5. ABGs are typically transported at room temperature if analyzed ASAP; if sample cannot be analyzed ASAP, put the sample on ice and make sure the sample's temperature remains between 1C and 5C during transport.
6. Inadequate volume of specimen for the test (QNS)
6. Make sure you have enough volume of the specimen for the test and in proportion to the anticoagulant in the syringe.
7. Prolonged delay in delivery to the lab
7. Make sure to deliver it to the lab for analysis ASAP; otherwise, put it on ice.
8. Wrong type of syringe used
8. Make sure to use a special heparin syringe to prevent clotting and prevent erroneous results.
A physician sends a patient to a hospital outpatient laboratory with the stat order shown below.
1. What effect does a high WBC have on ABGs?
WBCs continue to consume oxygen after collection. A high WBC count means that oxygen will be consumed at a higher rate than in a specimen with a normal WBC count.
2. How many draws will it take to collect specimens for all of the ordered tests?
Just one draw will be necessary, because ABGs and Lytes testing is a panel test.
3. What type of syringe should be used to collect the ABG specimen?
A special heparinized syringe should be used.
4. How should the specimen(s) be transported?
The specimen should be transported at room temperature and should be analyzed within 5 minutes of collection.
