Where is the best place to apply the tourniquet?
-
About 3 to 4 in. Above the venipuncture site
-
Distal to the venipuncture site on the forearm
-
Distal to the wrist bone if drawing a hand vein
-
Immediately above the venipuncture site.
Correct Answer
A. About 3 to 4 in. Above the venipuncture siteExplanation
The best place to apply the tourniquet is about 3 to 4 inches above the venipuncture site. This is because applying the tourniquet above the venipuncture site helps to occlude the veins and increase blood flow, making it easier to locate and access the veins for the procedure. Placing the tourniquet too close to the venipuncture site may cause discomfort or restrict blood flow too much, while placing it too far away may not provide enough occlusion for successful venipuncture.Rate this question:

In performing venipuncture, the needle is inserted:
-
As you prefer.
-
Bevel facing up.
-
Bevel site down.

There is a sign above the patient's bed that reads, "No blood pressures or venipuncture, right arm," the patient has an intravenous (IV) line in the left forearm. You have a request to collect a complete blood count (CBC) on the patient. How should you proceed?
-
Ask the patient's nurse to collect the specimen from the IV.
-
Ask the patient's nurse what to do when the sign is posted.
-
Collect a CBC from the right arm without using a tourniquet.
-
Collect the specimen from the left hand by finger puncture.
Correct Answer
A. Collect the specimen from the left hand by finger puncture.Explanation
The correct answer is to collect the specimen from the left hand by finger puncture. This is because the sign above the patient's bed specifically states that no blood pressures or venipuncture should be done on the right arm. Therefore, using a tourniquet and collecting a CBC from the right arm would go against this instruction. Asking the patient's nurse what to do when the sign is posted is not necessary as the sign already provides clear instructions. Collecting the specimen from the left hand by finger puncture is a safe and appropriate method to obtain the CBC without violating the instructions on the sign.Rate this question:

Outpatients who have previously fainted during a blood draw should be:
-
Allowed to sit up in order to carefully watch the draw.
-
Asked to lie down, or sit in a reclining drawing chair.
-
Drawn in a separate roam that has first-aid equipment.
-
Permitted to sit in a chair if accompanied by an adult.
Correct Answer
A. Asked to lie down, or sit in a reclining drawing chair.Explanation
Patients who have previously fainted during a blood draw should be asked to lie down or sit in a reclining drawing chair. This is because lying down or reclining helps to prevent fainting episodes by improving blood flow to the brain. It allows the patient to be in a more comfortable and relaxed position, reducing the likelihood of fainting during the procedure. Sitting up or being in a regular chair may not provide the same level of support and could increase the risk of fainting.Rate this question:

Correct Answer
A. NewbornExplanation
Newborns are the type of inpatient who are most likely to have more than one ID band.

These ID bands help to maintain the safety and security of newborns during their hospital stay.Rate this question:

When is the best time to release the tourniquet during venipuncture?
-
After the last tube has been filled completely
-
After the needle is withdrawn and covered
-
NsAs soon as blood begins to flow into the tube
-
As soon as the needle penetrates the skin
Correct Answer
A. NsAs soon as blood begins to flow into the tubeExplanation
The best time to release the tourniquet during venipuncture is as soon as blood begins to flow into the tube. Releasing the tourniquet at this point ensures that the blood flow is not obstructed and allows for a smooth and continuous collection of the sample. Releasing it too early, such as after the needle is withdrawn or covered, may result in inadequate blood flow and an incomplete sample. Similarly, releasing it after the last tube is filled completely may cause unnecessary discomfort to the patient. Releasing it as soon as the needle penetrates the skin is also not ideal as it may lead to excess bleeding before the collection process begins.Rate this question:

Doing this before obtaining a blood specimen from a child is a bad idea:
-
Establishing rapport which the child
-
Greeting the parents and the child
-
Telling the child it will not hurt
-
Telling the child what to expect
Correct Answer
A. Telling the child it will not hurtExplanation
Telling the child that the blood specimen will not hurt before obtaining it is a bad idea because it can create false expectations and lead to a loss of trust. If the child experiences pain during the procedure, they may feel betrayed and become fearful of future medical procedures. It is better to prepare the child for the possibility of discomfort while reassuring them that the healthcare professional will do their best to minimize any pain or discomfort.Rate this question:
