NEW QUESTION # 69
When using a bariatric blood pressure cuff instead of a tourniquet for an obese patient, the blood pressure cuff should be inflated to:
- A. Just below the patients systolic pressure
- B. Just below the patients diastolic pressure
- C. Just above the patient's diastolic pressure
- D. Just above the patient's systolic pressure
Answer: B
Explanation:
When using a bariatric blood pressure cuff instead of a tourniquet for an obese patient, the blood pressure cuff should be inflated to just below the patient's diastolic pressure. The phlebotomist should begin by measuring the patients' blood pressure and then adjusting the pressure. The cuff should not be so tight that it is painful for the patient Whereas most tourniquets are approximately 18 inches in length, bariatric tourniquets are available in longer lengths.
NEW QUESTION # 70
When collecting a blood specimen from a patient in an isolation room, the phlebotomist should place the collection tray:
- A. On a table or chair outside of the room
- B. On a table or chair immediately inside the room
- C. On the bedside table
- D. At the nurse's station or another secured area
Answer: D
Explanation:
When collecting a blood specimen from a patient in an isolation room, the phlebotomist should collect the needed supplies and place the collection tray at the nurse's station or in another secured area. The tray should not be left unattended in a public area. Any supplies taken into the isolation room are considered contaminated and cannot then be used for other patients, so they must be properly disposed of. Tourniquets used for isolation rooms should be dedicated to the patient or disposable.
NEW QUESTION # 71
Following capillary blood collection from a heel or finger, a bandage should be applied to the collection site of patients who are:
- A. 6 months or older
- B. 3 months or older
- C. 2 years or older
- D. 1 year or older
Answer: C
Explanation:
Following capillary blood collection from a heel or finger, a bandage should be applied to the collection site of patients who are 2 years old or older. Newborns and infants younger than 2 should not be bandaged for two reasons. First, the bandage may pose a choking risk because of the child's tendency to put things in the mouth. Second, the skin is too friable and may become irritated or tear when the bandage is removed.
NEW QUESTION # 72
The laboratory test that is most affected by hemolysis is:
- A. TP
- B. K
- C. Acid phosphatase
- D. Ca
Answer: C
Explanation:
Of the laboratory tests listed, the test that is most affected by hemolysis is K (potassium). Other tests that are equally affected include LH (lactate dehydrogenase), AST (aspartate aminotransferase), and the CBC (complete blood count). Fe (serum iron), ALT (alanine aminotransferase, and T4 (thyroxine) are also noticeably affected. Tests that are only mildly affected include P (phosphorous), TP (total protein), albumin, Mg (magnesium), Ca (calcium), and acid phosphatase.
NEW QUESTION # 73
Blood draws for a GTT in pregnancy are usually done at _______ after the test begins.
- A. 30 minutes, 60 minutes, 90 minutes, and 2 hours
- B. 2 hours, 4 hours, 6 hours, and 8 hours
- C. 1 hour, 2 hours, and 3 hours
- D. 30 minutes, 1 hour, 2 hours, and 4 hours
Answer: C
Explanation:
Blood draws for a GTT (glucose tolerance test) in pregnancy, which is done to screen for gestational diabetes, are usually done at I hour, 2 hours, and 3 hours after the test begins. Prior to beginning the timed portion of the test, a FBS (fasting blood sugar) is checked to ensure that the level is within a safe range. If so, the patient drinks the glucose solution within S minutes and the timed period of the test begins. The patient should be advised to eat no food and only drink water during the testing period. There are other variations of the GTT that require different testing intervals.
NEW QUESTION # 74
HCV exposure may occur through:
- A. Urine
- B. Phlebotomy procedures
- C. Semen
- D. Sexual contact
Answer: D
Explanation:
Hepatitis C virus (HCV) infection may occur through exposure to blood and serum and is primarily transmitted through sexual contact and needle sharing. However, it is rarely found in urine or semen and is not associated with phlebotomy procedures.
NEW QUESTION # 75
Which of the following statements regarding obtaining a blood specimen from a patient is FALSE?
- A. The name of the ordering physician on the ID band should not differ from that on the requisition form.
- B. Patient identity should always be verified.
- C. The phlebotomist should ask the patient's permission before collecting blood.
- D. The patient has the right to refuse the blood draw.
Answer: A
Explanation:
Occasionally, the name of the ordering physician, room number, or bed number on the patients ID band may differ from these details on the requisition form. Patient identity must always be verified before collecting blood. As part of informed consent, patients have the right to refuse any blood draw (with a few legal exceptions such as court-ordered drug testing); thus, the phlebotomist must ask the patients permission before collecting blood.
NEW QUESTION # 76
A primary function of the endothelium (tunica interna) of an artery is to:
- A. Promote blood clotting.
- B. Attach the artery to surrounding tissue.
- C. Provide elasticity to accommodate blood flow.
- D. Prevent blood clotting.
Answer: D
Explanation:
A primary function of the endothelium (tunica interna-the inner layer) of an artery is to prevent blood clotting through secretion of biochemicals that inhibit platelet aggregation. The endothelium provides a smooth surface for the blood to flow through and secretes substances that constrict or dilate the arteries. The middle layer is the tunica media, which is the thickest part of the arterial wall. The tunica media contains muscle and connective tissue to provide strength and elasticity. The tunica externa (the outer layer, aka tunica adventitia), attaches the artery to the surrounding tissue.
NEW QUESTION # 77
For most POC pregnancy tests, when is the earliest point at which the test will be accurate?
- A. 14 days after unprotected sex
- B. Anytime
- C. I day after a missed period
- D. I week after a missed period
Answer: C
Explanation:
For most point-of-care (POC) pregnancy tests, the earliest time at which the test will be accurate is 1 day after a missed period. If the patient is unsure about when her period is due, then the test can be taken 21 days after unprotected sex Some newer tests are now able to detect pregnancy even before a missed period. However, testing too early can sometimes produce a false negative, so tests taken after a missed period are usually more accurate. Testing is carried out with a urine sample.
NEW QUESTION # 78
To prevent hemoconcentration during venipuncture, the phlebotomist should:
- A. Massage the area until a vein is located.
- B. Ask the patient to vigorously pump his or her fist.
- C. Ask the patient to release his or her fist when blood flow begins.
- D. Redirect the needle several times until a vein is located.
Answer: C
Explanation:
To prevent hemoconcentration during venipuncture, the phlebotomist should ask the patient to release his or her fist when blood begins to flow: fist-pumping may increase blood potassium levels and should not be encouraged. Excessively massaging the site or probing or redirecting the needle multiple times may result in hemoconcentration.
NEW QUESTION # 79
Under which of the following conditions is underfilling additive tubes NOT acceptable?
- A. As a time-saving strategy
- B. When drawing blood from anemic patients
- C. When drawing blood from children
- D. When using a red top or SST
Answer: A
Explanation:
Underfilling additive tubes as a time-saving device is unacceptable. Underfilling is acceptable when obtaining larger amounts of blood is inadvisable, such as when drawing blood from infants, children, or severely anemic adults. Short-draw serum tubes such as red tops and serum separator tubes (SSTs) are acceptable provided that the specimen is not hemolyzed and there is enough of the specimen for testing.
NEW QUESTION # 80
If a patient reports a history of episodes of syncope, the most appropriate response is to:
- A. Provide smelling salts (ammonia inhalant).
- B. Place the patient in a recumbent position.
- C. Reassure the patient that venipuncture is not painful.
- D. Encourage the patient to do deep breathing and relaxation exercises.
Answer: B
Explanation:
If a patient reports a history of episodes of syncope, the most appropriate response is to place the patient in a recumbent position, either lying flat or reclining in a chair, so that he or she does not fall or experience injury if an episode of syncope occurs. Syncope is fainting that occurs with a sudden drop in blood pressure, and is sometimes associated with stress or fear. Patients who are fearful of needles or the sight of blood are especially at risk for syncope during venipuncture.
NEW QUESTION # 81
Which of the following is an example of vector transmission?
- A. Tuberculosis
- B. HIV
- C. Bubonic plague
- D. Salmonella infection
Answer: C
Explanation:
The transmission of bubonic plague by fleas from rodents is an example of vector transmission. Tuberculosis is spread via airborne transmission. Transmission of salmonella though handling contaminated food and transmission of human immunodeficiency virus (HIV) infection via a blood transfusion are examples of vehicle transmission.
NEW QUESTION # 82
The gray matter of the brain is composed of:
- A. Myelinated axons
- B. Nonmyelinated axons
- C. Schwann cells
- D. Synapses
Answer: B
Explanation:
The white matter of the brain is composed of myelinated axons; it is given its white color by the myelin sheath. Nonmyelinated axons are not covered by the myelin sheath and are known as the gray matter. Schwann cells produce the fatty substance that makes up the myelin sheath. Synapses are areas between neurons over which nerve impulses jump to transmit messages.
NEW QUESTION # 83
Which of the following tests requires that the specimen be chilled?
- A. CBC
- B. Lactic acid
- C. Potassium
- D. Uric acid
Answer: B
Explanation:
The specimen for a lactic acid test must be chilled. Other tests that require a chilled specimen include catecholamines, ammonia, pyruvate, adrenocorticotropic hormone, parathyroid hormone, metanephrines (plasma), and gastrin. Chilling the specimen slows the cell metabolism that otherwise continues and protects analytes that are altered by heat. Most specimens that require chilling are chilled in an ice-and-water slurry. A few specimens, such as homocysteine in the gel tube, are chilled on a cooler rack.
NEW QUESTION # 84
Which of the following activities is allowed in the laboratory?
- A. Pipetting by mouth
- B. Telephoning
- C. Smelling chemicals
- D. Drinking fluids
Answer: B
Explanation:
Telephoning such as to report a test result is allowed in the laboratory, although personal calls should not be made during working hours. Drinking and eating are prohibited in the lab. Other prohibitions include handling contact lenses, storing food for human consumption, pipetting by mouth, and smoking. Mechanical pipettes must be used because of the risk of ingesting substances when pipetting by mouth. Chemicals should never be tasted or smelled because of the risk of toxicity.
NEW QUESTION # 85
The hemoglobin A1c POC test reflects the average blood glucose level for the previous:
- A. 2-3 months
- B. 7-10 days
- C. 5 weeks
- D. 2-3 days
Answer: A
Explanation:
The hemoglobin A1c point-of-care (POC) test reflects the average blood glucose level for the previous 2-3 months. Glucose attaches to hemoglobin A in RBCs and remains for the life of the cells. The typical life of an RBC is approximately 120 days. Hemoglobin A1c is a better predictor of glucose control and the possibility of diabetes complications than serum glucose is. The normal value for hemoglobin A1c is less than 5.7%.
NEW QUESTION # 86
Intraoperative blood collection may be used in which type of surgery?
- A. Pediatric
- B. Cancer
- C. Lower GI tract
- D. Transplant
Answer: D
Explanation:
Intraoperative blood collection is used for procedures in which the estimated amount of blood loss is 20% or more of the patient's blood volume. The blood is collected from the incision site, filtered, washed, and returned to the patient via an IV: it is a form of auto transfusion. It is typically used in patients undergoing cardiac, vascular, gvmecologic, trauma, or transplant surgery. Intraoperative blood collection is not used for cancer or lower GI tract surgery or for infants or small children due to the risk of anemia or cardiac arrest.
NEW QUESTION # 87
Laboratory accreditation agencies generally require that laboratories follow the standards set by which of the following?
- A. CMS
- B. CAP
- C. FDA
- D. CLSI
Answer: D
Explanation:
Laboratory accreditation agencies generally require that laboratories follow the standards of the CLSI (Clinical and Laboratory Standards Institute). CLSI, a nonprofit membership agency, publishes the Procedures for the Collection of Diagnostic Blood Specimens by Venipuncture: Approved Standard, which outlines the order of draw. CLSI provides voluntary consensus standards, guidelines, and reports as well as supporting products, such as software and wall charts. CLSI is ANSI (American National Standards Institute) accredited.
NEW QUESTION # 88
If, after obtaining a blood sample, a phlebotomist accidentally experiences a needlestick that does not draw blood, the phlebotomist should:
- A. Wash the site with soap and water and take no further action.
- B. Wash the site with soap and water and report the incident.
- C. Flush the site with running water for 20 minutes and report the incident.
- D. Wipe the site with an alcohol swab and verify that there is no bleeding.
Answer: B
Explanation:
If a phlebotomist obtains a blood sample and then accidentally experiences a needlestick that does not draw blood, the phlebotomist should wash the site with soap and water. The incident must be reported as soon as possible to a supervisor, and needlestick protocol should be followed. This may include testing and/or prophylaxis for communicable diseases such as HIV, depending on the patients health history. In some cases, the patient may also be tested for communicable diseases in order to determine the risk to the phlebotomist.
NEW QUESTION # 89
During a blood draw and collection in multiple vacuum tubes, if the third tube fails to fill, the most appropriate initial response is to:
- A. Call for assistance.
- B. Insert the needle deeper into the vein.
- C. Discontinue the venipuncture and try a different site.
- D. Try a different vacuum tube.
Answer: D
Explanation:
During a blood draw and collection in multiple vacuum tubes, if the third tube fails to fill, the most appropriate initial response is to try a different vacuum tube. Tubes sometimes lose their vacuum. If the new tube also does not fill, then the phlebotomist should check to make sure that the entire bevel of the needle is completely under the skin. If a new tube does not solve the problem and the needle is in the correct place, the venipuncture may need to be discontinued and a new site tried.
