These are true in needle and
syringe preparation, except:
a. they must be sterile and dry e.
NIL
b. they must not be clogged
c. the syringe must be disposable
d. the needle must be fixed firmly into the hub of the syringe
3.
The tourniquet is applied in
this manner:
a. too tight to make veins
prominent e. NIL
b. not too tight nor too loose
c. loose to avoid hematoma
d. it does not matter how you apply it
4.
The following may be employed
to make veins prominent, except:
a. opening and closing the fist e.
NIL
b. palpating the vein
c. raising the arm
d. immersing the arm in warm water
5.
These are true in applying
antiseptic to site of puncture , except:
a. 70 % isopropyl alcohol is used e.
NIL
b. cleanse the site in a CIRCULAR manner
c. allow the site to dry before puncturing
d. sterilize once
6.
The following techniques are
observed in inserting the needle, except:
a. the ball of the pad of the index finger is placed alongside the hub
b. the bevel of the needle should be facing upwards
c. the angle of the needle and syringe should be 45 degrees
d. the needle should be held in line with the vein
e. NIL
7.
When withdrawing blood, the
following should be observed, except:
a. when the needle is in the vein, slowly pull back the plunger
b. keep your eyes on the needle
c. do not wiggle the needle around
d. when the needle is accidentally pulled out ,re-enter the vein
without removing the tourniquet to ensure non-entry of air
e. NIL
8.
If blood fails to enter the
syringe, the following may be the
reasons, except:
a. the needle is not in the vein
b. the needle has not gone far enough
c. the needle has gone through the vein
d. the tourniquet was tied too tightly
e. NIL
9.
In releasing the tourniquet,
the following should be observed, except:
a. before releasing the tourniquet, the fist should be opened
b. withdraw the needle first, before releasing the tourniquet
c. pull on either side of the tourniquet to release it
d. the tourniquet can be released as soon as blood enters the syringe
e. NIL
10. The following should be observed when withdrawing the needle,
except:
a. the needle should be jerked
out of the vein very rapidly to minimize pain
b. the needle should be withdrawn in a smooth gentle motion
c. an antiseptic pad is applied to the wound
d. the antiseptic can be
betadine
e. NIL
11. In transferring blood to the test tube, the following are observed,
except:
a. hold the plunger so that it does not slip out of the barrel
b. remove the needle from the syringe before dispensing blood
c. let the blood ooze at the sides of the tube
d. to avoid clotting, dispense rapidly by squirting directly into the
test tube
e. NIL
12. In cleaning the needle and syringe, the following are observed,
except:
a. if they are not disposable (glass), they should be washed
immediately
b. use tap water or distilled water to wash glass syringes
c. plastic syringes are disposed of properly
d. needles should not be thrown into
biohazard puncture proof –containers but recapped
13. Hematoma is the bluish discoloration of the skin which may be due to
the following, except:
a. failure have the needle
completely in the vein
b. failure to release the tourniquet before withdrawing blood
c. jerking the needle out of the vein
d. the needle is withdrawn smoothly
e. NIL
14. The following are advantages of venipuncture, except:
a. good for micro- determinations
b. large amounts of blood can be
collected
c. repeated determinations can be done
d. ideal for blood chemistry determinations
e. NIL
15. The following are drawbacks of venipuncture, except:
a. requires more time, skills and equipment
b. difficult to perform on infants
c. requires minute amount of blood which are difficult to collect
d. many complications can occur
e. NIL
