A
butterfly
16
Q

17
Q
Device used to deliver long term IV therapy ranging from weeks to years used for chemotherapy medication, blood or blood products hyper alimentation and monitoring central venous pressure. They’re also use for patients with poor veins to reduce the trauma of repeated IV starts. Increases patient comfort and helps reduce anxiety and patients who must have frequent venous access:
A
Central venous IV
18
Q
Small, flexible, plastic tube, the tip of which is placed in the superior or inferior vena cava or the right atrium. It is inserted to a central vein that is one that lives in the chest cavity or that is linked directly to the right atrium the main access veins used, or the internal and external jugular in the sub, clavicle veins Sometimes the femoral vein:
A
Central venous access device or catheter CVD or CVC
19

25
When a separate or secondary infusion line is needed the most popular set up is a:
medication administration set or Add-a-line or mini bag
26
The device that controls the intravenous infusion rate by monitoring either the drops per minute the IV said delivers for the volume of fluid delivered:
controller
27
A number of these pumps are available operating on different principles to deliver IV solutions, conveniently and accurately some units comprise more than one pump, allowing for the delivery of multiple IV solutions for one. Patient concurrently these devices, exert pressure on the IV tubing providing accurate delivery of a program volume offer, read outs of how much solution has infused at how much remains to be absorbed and will set an alarm if some thing obstruct the infusion or if the IV bag runs dry
electronic fusion pump
28
A mechanism by which a patient can self administer analgesic intravenously with the assistance of a computerized pump. It allows for the introduction of specific doses of preset intervals into the IV line.
patient controlled analgesia
29
A chamber added to an IV line between the bag and the line to control volumes more closely. It is used to ensure safety when the volume of fluid delivered must be carefully monitored often with children.
The Buritrol
30
No devices are needed. When gravity is used to deliver IV solution bag is on an IV port is held higher than the IV site solution drips into the tubing and into the patient vain by gravity, the nurse, regulates infusion rate by manually adjust in the roller clamp on the IV tubing to the required gtt/min
IV gravity based system
31
Device that provides intervenous access when needed without continuous infusion. It sits in the van, and must be flushed a specific intervals with saline solution or heparin solution.
Heparin, Hep-Lock, saline lock, PRN adaptor
32
A medication given into the vein or into an ongoing IV infusion, using a syringe and needle
IV push or IVP
33
Ivy orders must have the following components which provide the nurse with the information they required to carry them out:
flow rate
Start date
Stop date
Solution ordered
34
Common IV solutions:
Ringers lactate solution
2/3 and 1/3
D5W
Normal saline
5% dextrose and 0.9 NaCl.
0.45% NaCl.
35
IV solution containing water, electrolytes, sodium potassium, calcium chloride, used for milder cases of metabolic, acidosis for dehydration, and for shock, burn patients who have lost a lot of extra cellular fluid in order,l
Ringers lactate solution
36
IV solution one of the most frequently ordered, contains 3.3% glucose and 0.3% sodium chloride. Main purpose of the solution is maintaining adequate hydration, normal fluid balance. It is used for maintenance purposes versus restorative or resuscitative purposes.
2/3 and 1/3
37
IV solution also written as 5% DW means 5% dextrose in water solution is used primarily to replace water loss as in dehydrated patience and to provide some nutrients about 200 cal per liter. It is not provide electrolytes frequently used to keep the van open when the physician wants access to the van through an IV line but has not ordered a saline lock to keep the van open sometimes the physician order a certain amount of solution for hour and sometimes not.
D5W
38
Can also be written as 0.9% NaCl solution of pure ordinary salt made up of sodium and chloride in water, referred to as a physiological or isotonic because it will not alter normal electrolyte balance. It is used to treat patients who have lost a lot of body fluids as from hemorrhage, the solution restores electrolyte balance, but it’s not contain any calories, and unlike dextros solutions will not interfere with the sugar levels in a person with diabetes. It is the only intravenous fluid that may be run with blood. The moment the blood stops long, this solution will kick in. It is also used to flush the tubing … all IV meds are mixed in this solution and is used for keeping the vein open unless the patient is severely compromised with somesuch condition has congestive heart failure and should not have any also used to flush wounds and eyes because it’s not irritating
Normal Saline
39
The solution is used to treat, dehydration, another fluid for daily maintenance of body, fluids, and nutrition. It is similar to normal saline.
D5NS 5% dextrose and 0.9 NaCl
40
this has equal proportions of sodium and chloride, but half the sodium chloride of normal saline is often used to dilute acid in the blood when a patient is experiencing metabolic acidosis a condition in which the body is too acidic. It may be a better maintenance fluid, if larger amounts have to be administered.
0.45% NaCl
41
med given to hemophiliacs for clotting:
Factor VIII or 8 or cryoprecipitate
42
Why would a surgeon order prophylaxis
Blood usually packed cells available for patients having major surgery in case of excessive blood loss during surgery crossmatch for a patient and held in love for him or her
43
 When someone has two fewer red blood cells their number causes is usually treated with the infusion of packed cells
anemia
44
Any situation in which a person loses an excessive amount of blood usually over 750 cc is called hemorrhage. This causes the body to go into shock most effective way to treat massive haemorrhage is by blood replacement.
acute blood loss
45
Before receiving a blood transfusion, patient must have a:
Group and screen, and then the blood must be crossmatch
46
Types of blood products:
whole blood
Platelets

Cryo-precipitate
47
Ordered as a unit of blood approximately 520 cc of donated blood maybe used to treat excessive blood loss resulting from trauma surgery or burns but is not frequently ordered
Whole blood
48
Extracted from whole blood in order for someone with thrombocytopenia or a low blood platelet count. Anyone with these is at risk for bleeding disorder in particular disseminated, intravascular coagulopathy, potentially fatal condition, characterized by widespread bleeding, and these are ordered by the unit.
Platelets
49
derived from whole blood contains all coagulation or clotting factors and is given to patients with coagulation defects. One unit is approximately 225 cc
Fresh, frozen plasma
50
This most commonly ordered blood product, red blood cells separated from whole blood by a process, called centrifugation may be used to correct anaemia when extra volume is not desirable for a patient because it does not contain white blood cells opposes less risk of minor reactions doctor might order crossing type for two units
Packed cells
51
This is a protein extracted from the blood, and is often used to expand fluid volume within the blood vessels
Albumin
52
Part of the fresh, frozen plasma that contains a clotting factor called factor VIII it is most commonly given to patients with haemophilia to help control bleeding
cryoprecipitate
53

cross-matched and typed (group & cross)
54
factors affecting nutritional needs:
genetics
age
gender
pregnancy
activity
illness
55
how does genetics affect nutritional needs?
basal metabolic rate is amount of energy expended in a given period
56
how does age affect nutritional needs?
metabolic rate usually slows with age, fewer calories required
57
how does gender affect nutritional needs?
men tend to need more calories than woman because they are larger and have more muscle mass
58
how does pregnancy affect nutritional needs?
Adjust daily caloric intake to ensure health/well nourished baby. Diet high in protein is important
59
how does activity affect nutritional needs?
uses more calories/increases metabolic rate…less activity means u require less calories
60
how does illness affect nutritional needs?
extra calories/protein are needed to promote tissue repair & recovery. Fever raises metabolic rate as does trauma such as surgery
