A profile is
- A.
  
  A general screening test
- B.
  
  A quantitative laboratory test
- C.
  
  A number of related laboratory test
- D.
  
  Dorsal view of the patient
Correct Answer
C. A number of related laboratory test

Explanation
The correct answer is "a number of related laboratory tests." This means that a profile refers to a collection or group of laboratory tests that are related to each other in some way. It suggests that these tests are conducted together to provide a comprehensive evaluation of a specific aspect or condition being assessed.

A specimen is
- A.
  
  The removal of blood from the antecubital veins
- B.
  
  A small representative of body sample
- C.
  
  The surgical removal and examination of tissue
- D.
  
  The clinical analysis of urine sample
Correct Answer
B. A small representative of body sample

Explanation
The correct answer is "a small representative of body sample." A specimen refers to a small portion or sample of a larger entity, in this case, a body sample. It is commonly used in medical and scientific contexts to analyze and study various aspects of the body, such as cells, tissues, or fluids. By examining a specimen, healthcare professionals and researchers can gain insights into the overall health and functioning of an individual.

The purpose of cleansing the site selected for venipuncture is
- A.
  
  To cause the veins to be more prominent
- B.
  
  To allow blood flow to the area
- C.
  
  To decrease circulation in the arteries
- D.
  
  To carry microorganisms away from the puncture site
Correct Answer
D. To carry microorganisms away from the puncture site

Explanation
The purpose of cleansing the site selected for venipuncture is to carry microorganisms away from the puncture site. Cleansing the site helps to remove any dirt, bacteria, or other microorganisms present on the skin, reducing the risk of introducing them into the bloodstream during the venipuncture procedure. This helps to prevent infection and ensure the safety of the patient.

The following may cause hematoma
- A.
  
  Pressure applied to the puncture site after the needle is removed
- B.
  
  Removing the tourniquet before the needle is removed
- C.
  
  Using proper venipuncture technique
- D.
  
  Inserting the needle through the vein and puncturing the opposite wall
Correct Answer
D. Inserting the needle through the vein and puncturing the opposite wall

Explanation
Inserting the needle through the vein and puncturing the opposite wall can cause hematoma because it can result in damage to the surrounding tissues and blood vessels. This can lead to bleeding and the accumulation of blood in the area, causing a hematoma to form. The other options mentioned, such as pressure applied to the puncture site after the needle is removed or removing the tourniquet before the needle is removed, may cause minor bleeding but are less likely to result in a hematoma. Using proper venipuncture technique is important to minimize the risk of complications, including hematoma formation.

The purpose of the tourniquet is to
- A.
  
  Increase pressure and the prominence of veins
- B.
  
  Prevent hematoma
- C.
  
  Decrease oxygen level
- D.
  
  Monitor blood pressure
Correct Answer
A. Increase pressure and the prominence of veins

Explanation
A tourniquet is a device used to apply pressure to a limb or extremity to control bleeding. By increasing pressure, it constricts blood vessels and promotes the prominence of veins. This helps in improving the visibility and accessibility of veins, making it easier to perform medical procedures such as drawing blood or inserting an IV. The other options, preventing hematoma, decreasing oxygen level, and monitoring blood pressure, are not the primary purposes of a tourniquet.

Whole blood is obtained
- A.
  
  By using a tube containing an anticoagulant
- B.
  
  By centrifuging a clotted specimen
- C.
  
  By using a red stoppered tube
- D.
  
  By using a tube that doesnt contain an anticoagulant
Correct Answer
A. By using a tube containing an anticoagulant

Explanation
Whole blood is obtained by using a tube containing an anticoagulant because anticoagulants prevent the blood from clotting. When blood is drawn into a tube with an anticoagulant, it ensures that the blood remains in a liquid state, which is necessary for various laboratory tests and procedures. Without an anticoagulant, the blood would clot, making it unsuitable for certain analyses. Therefore, using a tube containing an anticoagulant is the correct method for obtaining whole blood.

Venipuncture needles should be discarded
- A.
  
  Directly into the garbage
- B.
  
  They are reused not disgarded
- C.
  
  Directly into an autoclave bag
- D.
  
  Into a sharps container
Correct Answer
D. Into a sharps container

Explanation
Venipuncture needles should be discarded directly into a sharps container because they are considered biohazardous waste. Sharps containers are specifically designed to safely contain and dispose of sharp objects such as needles to prevent injuries and the spread of infections. Discarding the needles into the garbage or an autoclave bag would not provide the same level of safety and could potentially put others at risk. Additionally, the statement that the needles are reused is incorrect, as single-use needles should never be reused.

If a vein feels lumpy or ropey when palpated it is probably
- A.
  
  Flabby
- B.
  
  Deep
- C.
  
  Tortuous
- D.
  
  Superficial
Correct Answer
C. Tortuous

Explanation
If a vein feels lumpy or ropey when palpated, it is likely to be tortuous. This means that the vein is twisted or has a winding course. This can be caused by various factors such as aging, genetics, or certain medical conditions. When a vein becomes tortuous, it may appear swollen or bulging, and can sometimes be painful.

Ferhentine to Celsius
- A.
  
  5/9(F-32)
- B.
  
  9/5+32 (C)
- C.
  
  5/9-32F
- D.
  
  9/5(C+32)
Correct Answer
A. 5/9(F-32)

Explanation
The given equation, 5/9(F-32), is the correct formula to convert temperature from Fahrenheit to Celsius. This formula involves subtracting 32 from the Fahrenheit temperature and then multiplying the result by 5/9. This conversion is necessary because the Fahrenheit scale uses a different zero point and different size units compared to the Celsius scale.

Which term means death of the heart muscle
- A.
  
  Myocardial infarction
- B.
  
  Angina pectoris
- C.
  
  Cardiomyopathy
- D.
  
  Myocardial angina
Correct Answer
A. Myocardial infarction

Explanation
Myocardial infarction refers to the death of the heart muscle due to a lack of blood supply. This occurs when there is a blockage in the coronary arteries, which are responsible for supplying oxygenated blood to the heart. The blockage can be caused by a blood clot or a buildup of plaque in the arteries. Without proper blood flow, the heart muscle becomes damaged and can eventually die. This condition is commonly known as a heart attack. Angina pectoris refers to chest pain or discomfort that occurs when the heart muscle does not receive enough blood and oxygen. Cardiomyopathy is a disease of the heart muscle that affects its ability to pump blood effectively. Myocardial angina is not a recognized medical term.
