Question 1

Which of the following tests is affected by the patient's position?&#10;A) Chloride&#10;B) PT&#10;C) Protein&#10;D) Sodium

Accepted Answer

Protein levels can be affected by the patient's position due to changes in plasma volume. When a person moves from a lying to a standing position, there is a decrease in plasma volume, which can lead to a relative increase in protein concentration.

Question 2

Collections for which department require a special patient identification system in addition to the hospital ID bracelet?&#10;A) Blood bank&#10;B) Chemistry&#10;C) Coagulation&#10;D) Hematology

Accepted Answer

Blood bank collections require a special patient identification system in addition to the hospital ID bracelet due to the importance of accurate patient identification for blood transfusion safety.

Question 3

What is the term used to describe a vein that is hardened due to repeated venipunctures, chemotherapy, or disease?&#10;A) Blocked&#10;B) Edematous&#10;C) Occluded&#10;D) Sclerosed

Accepted Answer

A vein that is hardened due to repeated venipunctures, chemotherapy, or disease is called a sclerosed vein.

Question 4

What condition can be caused by the removal of lymphoid tissue as part of a mastectomy?&#10;A) Anemia&#10;B) Hemoconcentration&#10;C) Lymphostasis&#10;D) Syncope

Accepted Answer

Lymphoid tissue is important for the immune system and drainage of fluids. Removal of this tissue can cause lymphostasis, a condition where lymphatic vessels cannot properly drain fluids, leading to swelling and potential infection. Anemia, hemoconcentration, and syncope are not directly related to the removal of lymphoid tissue.

Question 5

What is the maximum amount of time that a tourniquet can be left on?&#10;A) 30 seconds&#10;B) 1 minute&#10;C) 2 minutes&#10;D) 5 minutes

Accepted Answer

The answer of What is the maximum amount of time...

Question 6

A large amount of bleeding into the tissues surrounding a puncture site (i.e., in a patient who takes anticoagulant medication) can cause what condition?&#10;A) Compartment syndrome&#10;B) Infection&#10;C) Nerve damage&#10;D) Vein collapse

Accepted Answer

Compartment syndrome is a condition in which increased pressure within a muscle compartment causes decreased blood flow, which can lead to muscle and nerve damage. Bleeding into the tissues surrounding a puncture site can increase pressure within the muscle compartment, especially in patients taking anticoagulant medication, which can prolong bleeding. This can lead to compartment syndrome. Infection, nerve damage, and vein collapse are not directly related to bleeding into the tissues.

Question 7

Which of the following can cause hemolysis of a blood specimen?&#10;A) Using a needle with a larger gauge than necessary&#10;B) Not mixing the tubes that contain anticoagulant&#10;C) Using a small-gauge needle and a large vacuum tube&#10;D) Using a syringe to draw the specimen

Accepted Answer

Using a small-gauge needle and a large vacuum tube can cause hemolysis of a blood specimen, as the force of the vacuum can cause the red blood cells to rupture.

Question 8

During a prolonged hospitalization, a patient requiring many lab tests may develop what condition as a result of multiple blood samples being drawn?&#10;A) Anemia&#10;B) Edema&#10;C) Hemoconcentration&#10;D) Reflux

Accepted Answer

Multiple blood samples being drawn over a prolonged hospitalization can lead to anemia, as it can result in a decrease in the number of red blood cells and hemoglobin in the bloodstream. This can be especially problematic for patients who are already anemic or have conditions that put them at risk for anemia. Edema, hemoconcentration, and reflux are not directly related to the frequent drawing of blood samples.

Question 9

A patient has a seizure while you are performing a venipuncture. What should you do?&#10;A) Finish collecting the specimen and then call the nurse for help.&#10;B) Remove the tourniquet and needle immediately and call the nurse for help.&#10;C) Call the lab for help restraining the patient so you can obtain the sample.&#10;D) Ignore the seizure and continue the procedure as usual.

Accepted Answer

The safety and well-being of the patient should always be the top priority. Therefore, the needle and tourniquet should be removed immediately to prevent any injury to the patient. Once this is done, the nurse should be called to assist in managing the seizure and providing any necessary medical attention. Collecting the specimen can wait until the patient's safety is secured.

Question 10

What is the medical term for fainting?&#10;A) Emesis&#10;B) Hematoma&#10;C) Lymphostasis&#10;D) Syncope

Accepted Answer

Syncope is the medical term for fainting, which is a temporary loss of consciousness due to a lack of blood flow to the brain. Emesis refers to vomiting, hematoma refers to a collection of blood outside of blood vessels, and lymphostasis refers to the stagnation of lymphatic fluid.

Question 11

Which of the following may cause a hematoma?&#10;A) Going through the back side of the vein when inserting the needle&#10;B) Using a needle of too-small gauge&#10;C) Using a needle of too-large gauge&#10;D) Leaving the tourniquet on for longer than 1 minute

Accepted Answer

The answer of Which of the following may cause a...

Question 12

The emergency department has requested a that blood alcohol level be drawn on a patient. What is the proper way to obtain the specimen?&#10;A) Clean the site with alcohol and perform a routine venipuncture.&#10;B) Clean the site with Betadine (povidone-iodine) and perform a routine venipuncture.&#10;C) Call the lab to get a phlebotomist who is experienced in drawing from arteries.&#10;D) Use alcohol to clean the site and perform a dermal puncture.
