wk 10 study questions

Question 1

perivascular placement

Answer 1

Placement of the needle outside of the blood vessel

Question 2

You are restraining a dog for the administration of an intravenous drug into the animal’s cephalic vein. The needle has been placed into the vein and the person administering the drug is ready to give it. Should you release your digital pressure from the vein as the drug is being administered?

Answer 2

Release your pressure so the drug may enter the vessel if pressure is maintained the drug will not have anywhere to go

Question 3

You are restraining a dog for the purpose of obtaining a blood sample. The needle has been inserted into the vein and the person drawing the blood sample is ready to withdraw the sample. Should you continue to distend the vein or release your digital pressure from the vein as the sample is being drawn?

Answer 3

Maintain pressure because if pressure is released the vein will collapse

Question 4

occluded

Answer 4

Pressure is being applied to stop the blood flow in order to draw a sample; “press and roll” and tourniquet

Question 5

why must the aspiration of the blood sample into the collecting syringe not be done too forcefully

Answer 5

may cause vein to collapse, pain to
patient, and hemolysis

Question 6

Three reasons why a liberal amount of alcohol is applied to the venipuncture site prior to the procedure

Answer 6

Alcohol cleans hair, wets down the hair, and helps visualize the vein

Question 7

The name and location of the 3 veins that are most commonly used when obtaining a blood sample from the dog are?

Answer 7

cephalic, saphenous, jugular

Question 8

What should be done when transferring a blood sample to a blood tube from the syringe that the sample was collected in?

Answer 8

• remove needle
• remove stopper
• squirt sample into tube
• replace stopper and gently invert sample to mix
  *To reduce hemolysis and damage to blood cell

Question 9

EDTA

Answer 9

anticoagulant

Question 10

Why shouldn’t tubes containing a blood sample be shaken vigorously?

Answer 10

can cause hemolysis of sample

Question 11

You are going to obtain a blood sample for a routine CBC on Toby. The procedure used in this clinic is to transfer the sample from the collection syringe to a vacutainer blood tube. There are a number of tubes available that are used for different tests. What type should you use for this situation? How will you distinguish the proper tube from the others?

Answer 11

A tube containing EDTA; Color and label indicating edta (purple)

Question 12

When venipuncture is to be performed on the right cephalic vein, what side of the animal should the restrainer stand?

Answer 12

left side

Question 13

hematoma? causes? prevent it? treat it?

Answer 13

• Blood pooling under the skin
• Pulling out too soon, not enough pressure after pulling out, and “jabbing blindly”
• Say “release” apply pressure for min 10 seconds

Question 14

Where is the medial saphenous vein located? another name?

Answer 14

Medial aspect of rear leg; femoral vein

Question 15

The medical saphenous vein can be used to obtain small blood samples or administer intravenous drugs. One problem that this vessel is particularly prone to when used for venipuncture is How can the severity of the problem be lessened?

Answer 15

Hematomas; Small needle, pressure applied immediately and longer than normal

Question 16

Give 2 reasons why some medication must be administered intravenously?

Answer 16

drug must rapidly reach high blood levels, drug would be highly irritating or cause tissue necrosis administered IM or SC, insufficient absorption would take place if administered by IM or SC route

Question 17

The most common vessel used to give drugs intravenously to dogs is?

Answer 17

cephalic

Question 18

You are preparing supplies to obtain a blood sample. You have attached the correct size needle to the syringe. What else should you do to the syringe to prepare it for the procedure? Why?

Answer 18

Loosen the plunger; To avoid excess pressure when aspirating

Question 19

When inserting a needle into a vein, what position should the needle “bevel” be in?

Answer 19

up

Question 20

You have performed venipuncture and successfully obtained a blood sample. You had prepared the syringe by adding 1 drop of EDTA prior to performing the venipuncture. What should you do with the syringe immediately after obtaining the sample?

Answer 20

Sample should be mixed to distribute edta into sample

Question 21

Certain drugs can only be given intravenously. Why?

Answer 21

Irritating to tissues

Question 22

necrosis? How is it relevant when considering intravenous injections?

Answer 22

Tissue becomes inflamed and necrotic; If the injection goes perivascular, necrosis may occur
