Question 1

Before urinalysis testing, a urine specimen needs to be in which of the following states?&#10;A) Filtered and at refrigerator temperature&#10;B) At room temperature and well-mixed&#10;C) Centrifuged and at room temperature&#10;D) At body temperature and well-mixed

Accepted Answer

Before urinalysis, a urine specimen should be at room temperature and well-mixed to ensure that the test results accurately reflect the substances present in the urine. This helps in obtaining a uniform sample for analysis.

Question 2

Which of the following is a recording of the electrical activity of the heart?&#10;A) Cardiac troponin&#10;B) BNP&#10;C) ECG&#10;D) PTT

Accepted Answer

ECG (electrocardiogram) is a recording of the electrical activity of the heart, which shows the heart's rhythm, rate, and any abnormalities. Cardiac troponin and BNP are blood tests used to diagnose heart damage and heart failure, respectively. PTT (partial thromboplastin time) is a blood test used to monitor the effectiveness of blood-thinning medications.

Question 3

The detection of HCG in a patient sample is useful in the diagnosis of what condition?&#10;A) Anemia&#10;B) Heart attack&#10;C) Kidney disease&#10;D) Pregnancy

Accepted Answer

HCG, or human chorionic gonadotropin, is a hormone produced by the placenta during pregnancy. Therefore, the detection of HCG in a patient sample is useful in the diagnosis of pregnancy.

Question 4

What type of sample is used for a rapid strep test?&#10;A) Blood&#10;B) Feces&#10;C) Throat swab&#10;D) Urine

Accepted Answer

A throat swab is used for a rapid strep test.

Question 5

A normal electrocardiogram (ECG or EKG) consists of a tracing of five prominent points, which are abbreviated in what manner?&#10;A) A B C D E&#10;B) J K L M N&#10;C) P Q R S T&#10;D) V W X Y Z

Accepted Answer

P Q R S T are the five prominent points in a normal ECG and they stand for the electrical events that occur during one heartbeat. A B C D E are used to denote different waves and segments in certain ECG interpretations, but not in a normal ECG. J K L M N and V W X Y Z are not used in any ECG interpretations.

Question 6

Which of the following procedures is important when drawing blood at a patient's home and is not necessary in a hospital building?&#10;A) Be sure the patient is sitting or reclining in a safe position.&#10;B) Carry a cell phone for emergencies.&#10;C) Make sure the patient has stopped bleeding before leaving.&#10;D) Ensure that the materials used during the procedure are properly removed and disposed of.

Accepted Answer

Carrying a cell phone for emergencies is specifically important when drawing blood at a patient's home because it ensures the phlebotomist can call for help if an emergency arises, unlike in a hospital where help is readily available.

Question 7

Which of the following agencies decides whether a given test is a CLIA-waived test?&#10;A) AMA&#10;B) CLIA&#10;C) FDA&#10;D) OSHA

Accepted Answer

The FDA (Food and Drug Administration) is responsible for deciding whether a given test is CLIA-waived, based on its complexity and the potential risk of erroneous results.

Question 8

Blood levels of which of the following analytes are increased in congestive heart failure?&#10;A) APTT&#10;B) BNP&#10;C) Cardiac troponin&#10;D) PT

Accepted Answer

Blood levels of B-type natriuretic peptide (BNP) are increased in congestive heart failure. APTT and PT are coagulation tests and are not directly related to heart failure, while cardiac troponin is increased in myocardial infarction but not specific to heart failure.

Question 9

A complete heartbeat, consisting of depolarization and repolarization, is also known as which of the following?&#10;A) Cardiac cycle&#10;B) Conduction cycle&#10;C) P-wave cycle&#10;D) Sinoatrial cycle

Accepted Answer

The cardiac cycle refers to the complete sequence of events that occurs during a single heartbeat, including depolarization and repolarization. The other answer choices, such as the conduction cycle, P-wave cycle, and sinoatrial cycle, refer to specific aspects of the heart's electrical activity but do not encompass the entirety of a single heartbeat.

Question 10

Coumadin (warfarin) therapy can be monitored using which of the following tests?&#10;A) ACT&#10;B) APTT&#10;C) Potassium&#10;D) PT

Accepted Answer

PT (prothrombin time) is the preferred test to monitor Coumadin therapy as it measures the clotting time of the extrinsic pathway of coagulation, which is affected by Coumadin. A higher PT indicates that the patient is more anticoagulated, while a lower PT indicates that the patient is less anticoagulated. ACT (activated clotting time) and APTT (activated partial thromboplastin time) are tests used to monitor heparin therapy, not Coumadin therapy. Potassium is not a test used to monitor Coumadin therapy.

Question 12

Which of the following is a POCT used to screen for colon cancer and gastric ulcers?&#10;A) Cardiac troponin T&#10;B) BNP&#10;C) Occult blood&#10;D) PTT
