Q

What are nursing implications for the administration of all blood components, including donation, processing, and administration, and complications?

A

DONATION
American Red Cross donation requirements
Type and Cross
A, B, O, AB
Rh+ & Rh –
FFP requires ABO but not Rh compatibility
Platelets are not typically cross-matched for ABO compatibility
Testing
Autologous donation
Intraoperative blood salvage- cannot be stored

TRANSFUSION
Blood Administration
Only with NS, Never medications or other fluids through blood tubing
Never medications or other fluids through blood tubing
Only through appropriate filter tubing, change tubing after 2 units (check hospital policy)
Administration time per unit should not exceed 3 ½ hours
Platelets or FFP:
Infuse each unit over 30-60 minutes
FFP requires ABO but not Rh compatibility testing
Platelets typically not cross-matched
steps:
verify Dr order- hgb of 10- anemic, below 8- needs blood transfusion
Obtain consent
Assess IV site & patency
Obtain blood from blood bank
Check accuracy of blood label and pts ID
Baseline VS & assessment
Start the infusion
VS & assessment recheck
Monitor transfusion reactions

complications: occurs in the first 10-15 minutes or first 50cc of blood
Febrile nonhemolytic reaction- chills, fever, HA, flushing tachycardia, anxiety
Acute hemolytic reaction- low back pain, hypotension, tachycardia, fever & chills, chest pain, tachypnea, hemoglobinuria, can be immediate
Allergic reaction- hives, pruritus, facial flushing, SOA, brochospasm, anxiety
Circulation overload-
Bacterial contamination-
Disease acquisition- Hepatitis, AIDS

implications
stop transfusion (maintain line with normal NS) & notify DR
change IV tubing
treat symptoms
recheck crossmatch record with unit
hemolytic reactions-
obtain 2 blood samples distal to infusion site
obtain first UA- test for hemoglobinuria
monitor F & E

Q

chronic myeloid leukemia

A

Increases with age – 65 average
See it rarely under 20
Men more likely to get it

Pathophysiology- a genetic change takes place in an early (immature) version of myeloid cells - the cells that make red blood cells, platelets, and most types of white blood cells (except lymphocytes). The leukemia cells grow and divide, building up in the bone marrow and spilling over into the blood. In time, the cells can also settle in other part of the body, including the spleen.

22
Q

chronic lymphoid leukemia

A

Pathophysiology- In chronic leukemia, the cells can mature partly but not completely. They generally do not fight infection as well as normal white blood cells do. The leukemia cells survive longer than normal cells, and build up, crowding out normal cells in the bone marrow.

27
Q

Type I Diabetes

A

Destruction of pancreatic beta cells
Decreased insulin production,
Increased glucose production by liver
Fasting hyperglycemia

Glucose derived from food cannot be stored in liver but instead remains in bloodstream = post-parandial (after meals) hyperglycemia

28
Q

Type II Diabetes

A

Insulin resistance = decreased tissue sensitivity to insulin
Intracellular reactions are diminished – making insulin less effective at stimulating glucose uptake by the tissue

Impaired insulin secretion

Usually a slow progression and can go undetected for many years

29
Q

Diabetic Ketoacidosis (DKA)

A
  1. Hyperglycemia: There is no insulin, so no glucose entering the cells, All the glucose is in the bloodstream , And production and release of glucose by the liver is increased
  2. Dehydration and electrolyte loss: The kidneys attempt to rid the body of the excess glucose , Glucose – along with water and electrolytes – are excreted
  3. Metabolic acidosis: Breakdown of fat (lipolysis) to free fatty acids and glycerol occur  The free fatty acids are then converted into ketone bodies by the liver  Ketone bodies accumulate leading to metabolic acidosis

occurs with type 1 diabetes

clinical manifestations
Clinical Manifestations
Polyuria
Polydipsia
Marked fatigue
Blurred vision 
Weakness
Headache
Orthostatic hypotension 
GI symptoms (nausea, vomiting, abdominal pain)
Acetone breath (fruity odor)
Hyperventilation w/ very deep (not labored) respirations - Kussmaul
Mental status changes 

Assessment and Diagnostic Findings
High blood glucose (300-800 mg/dL)
Low serum bicarbonate (0-15 mEq/L)
Low serum pH (6.8-7.3)
Presence of ketone bodies in blood and urine
Depending on amount of water loss:
Sodium and Potassium may be low, normal, or high
Creatinine, BUN, and hematocrit may be high

Decreased or missed dose of insulin
Illness or infection
Undiagnosed/untreated diabetes

Management
Rehydration: (Fluid loss from polyuria, hyperventilation, diarrhea, and vomiting)
GIVE IV FLUIDS!!!
May need as much as 6-10 L
Start with NS at rapid rate – 0.5-1L per hour for 2-3 hours
Then ½NS for continued rehydration for several more hours
When blood glucose reaches 300 or less – switch to D5W to prevent decline in blood glucose level
MONITOR FLUID VOLUME STATUS!!!
Frequent vital signs
Lung assessments
Monitoring intake and output
Monitor for signs/symptoms of fluid overload

Restoring Electrolytes: IV potassium slowly
POTASSIUM REPLACEMENT!!!!
As much as 40 mEq/hour may be needed for several hours to avoid dysrhythmias that occur with hypokalemia
Frequent ECG and lab monitoring

Reversing Acidosis
GIVE INSULIN!!!!
IV Regular insulin is given at a slow, continuous rate
Hourly blood glucose measurements
Blood glucose levels are usually corrected before acidosis is corrected  IV insulin may be continued for 12-24 H until serum bicarbonate levels increase to at least 15-18 mEq/L

SICK DAY RULES
Never eliminate insulin doses when nausea and vomiting
Take insulin dose and then attempt to consume frequent small portions of carbs
Drink fluids every hour to prevent dehydration
Assess blood glucose and urine ketones every 3-4 hours

If patient cannot take fluids without vomiting, or if elevated glucose or ketone levels persist – call provider!

Monitoring and Managing Potential Complications
Fluid Overload
Hypokalemia
Cerebral Edema

30
Q

Hyperglycemic Hyperosmolar Syndrome (HHS)

A
  1. Hyperglycemia: Lack of effective insulin to prevent hyperglycemia , but enough insulin is present to prevent the breakdown of fat , So no ketosis and acidosis occur
  2. Hyperosmolarity: Persistent hyperglycemia causes osmotic diuresis , results in loss of water and electrolytes
Clinical Manifestations
Hypotension 
Dehydration 
Tachycardia
Variable neurologic signs 

Assessment and Diagnostic Findings
High blood glucose (600-1200 mg/dL)
Osmolality (>320 mOsm/kg)
High BUN and Creatinine

Causes
Infection or acute illness
Medications that exacerbate hyperglycemia
Treatments such as dialysis

Management
Rehydration
Restoring Electrolytes
Insulin Administration

Rehydration
Very similar to management in DKA
Restoring Electrolytes
Very similar to management in DKA
Insulin Administration
Less of important role because not needed for reversal of acidosis
Insulin is given at a continuous low rate

Monitoring and Managing Potential Complications

Keep blood flowing to feet
DO NOT – walk barefoot, use heating pads, wear open-toed shoes, soak the feet, shave calluses

33
Q

diabetes in the hospital

A

Blood glucose levels tend to increase due to stress

Management of glucose control very important during perioperative period
Frequent blood glucose monitoring
May need to use IV insulin
Monitor closely post-operative for cardiovascular complications, wound infections, and skin breakdown

change in diets
NPO
Usual dosage of rapid or intermediate acting insulin must be changed
Continue to give basal dose insulin
Frequent blood glucose monitoring
Clear Liquids
A lot of clear liquids contain simple carbohydrates – try to use diet types
Glucose tests and insulin administration should match mealtimes
Enteral Tube Feeding
Often results in increased levels of glucose
If continuous tube feeding, regularly scheduled intervals of insulin given
Must be cautious if tube feeding is temporarily discontinued or paused

HYPERGLYCEMIA DURING HOSPITALIZATION
Reasons:
Changes in usual treatment regimen
New medications introduced or routine medications changed
Use of IV dextrose in fluids
Overly vigorous treatments for hypoglycemia
Inappropriate withholding of insulin
Inappropriate use of “sliding scales”
Mismatched timing of meals and insulin
NURSING INTERVENTIONS
Nursing Interventions:

Monitor blood glucose levels
Test blood glucose before a meal served and administer insulin at that time
Use NS as much as possible, and not IV fluids with dextrose
Avoid overly vigorous treatment of hypoglycemia

HYPOGLYCEMIA DURING HOSPITALIZATION
Reasons:
Overuse of “sliding scale” insulin
Not changing insulin dosage when dietary intake is decreased
Overly vigorous treatment of hyperglycemia
