Minimum Urine Output
30mL / hr
Low urine output is a sign of hypovolemia or kindney injury
Isotonic
No net fluid shift into or out of RBCs
Fluid = blood
250-375 mOsm/L
Hypertonic
Pulls fluid out of RBCs and into ECF
>375 mOsm/L → High osmolality (fluid enters ECF)

Hypotonic
Fluid moves into RBCs from ECF
<250 mOsm/L → Low osmolality ( Less fluid in ECF)

Isotonic Solutions
TYPES
Normal Saline (0.9% NaCl)
Lactated Ringer’s
Dextrose 5% in Water (D5W)
D5W is isotonic in the bag but hypotonic in body after dextrose is metabolized (contraindicated in fluid resuscitation; hypotonic solution will worsen shock)
INDICATION
Used for fluid resuscitation. Expands ECF w/o causing 3rd spacing
RISKS
Fluid overload in elderly or pts with Heart Failure or Kidney Disease
Hypertonic Solution
TYPES
3 or 5% NaCl
Dextrose 10% in Water (D10W)
Dextrose 5% in NS
Dextrose 5% in LR
Parenteral Nutrition (TPN/PPN)
INDICATIONS
HYPOnatermia
Cerebral edema (due to increased ICP)
Nutritional Support
RISKS
Fluid overload & pulmonary edema
NURSING INTERVENTIONS
Infuse slowly & monitor serum Na closely
Hypotonic Solutions
TYPES
0.45% NaCl
0.33% NaCl
D5W (hypotonic in body)
D2.5W
INDICATIONS
Hypertonic dehydration
Hypernatermia
Gastric fluid loss
Maintenance fluids
RISKS
Avoid in patients at risk for increased intracranial pressure (stroke, head injury) or in third-spacing (ascites, burns, trauma)
Hypotonic causes cells to swell worsening edema that is already present.
Peripheral IV therapy
Assess site regularly and before use
Assess for pain, infiltration, burning, swelling, or redness
Label & document date, gauge, & site
Change continuous sets q96h & intermittent sets q24hrs
Saline Lock
A PIV that is capped & flushed between intermittent doses
Must keep insertion site visible under transparent dressing
Dressing should be clean, dry , & intact
Flushing
Used before and after PIV use to keep IV patent & push all medications into the body.
Uses 3-5 ml NS and up to 10ml
Never push flush against resistenance (may indicate occlusion, or infiltration)
Use slow-push method
Can CNAs flush IVs?
No, at least for most states. Answer is no on NCLEX
Phlebitis
Inflammation of vein wall
TYPES
Mechanical via catheter movement or size
Chemical via irritating drug/solutions
Bacterial
SIGNS

Palpable venous cord
Warmth
Pain & tenderness
Wwelling
GRADING
Use INS Phlebitis scale
TREATMENT
Stop infusion & remove catheter (if grade 2 and +)
Apply warm compress & elevate extremity
Give analgesics
Restart IV in opposite extremity
Culture purulent drainage
INS Phlebitis Scale
Grade 0: no symptoms
Grade 1: Erythema at site, with or w/o pain
Grade 2: Pain at site with erythema and edema
Grade 3: Pain, erythema, edema, streak formation, & palpable venous cord
Grade 4: Grade 3 + palpable venous cord >1 inch & purulent drainage
Infiltration
Non-vesicant solution (is not necrotic) leaks into surrounding tissue
SIGNS (Compare effected extremity with opposite extremity)
Swelling
Coolness
Blanching or taut skin (tight skin)
Slowed or stopped infusion
Leaking at site
Apply light pressure above site, if infusion keeps running, infiltration is likely (means that it is not in the vein)
NURSING ACTIONS
Stop infusion & remove catheter
Elevate & apply warm or cold compress (depending on solution)
Restart IV on opposite extremity
Grade with INS infiltration scale
Obstruction
Partial or complete blockage of catheter
CAUSES
Mechanical : Closed clamp, kinked tubing, extremity position, tight dressing
Thrombotic: Blood clot
Non-thrombotic: Drug or mineral precipitate
NURSING ACTIONS
Trace line from patient to the bag
Reposition extremity
Flush gently w/10mL diameter syringe
NEVER force the flush. If occlusion continues, remove & restart
Extravasion
Vesicant solution leaks into surrounding tissue
Most dangerous complication; causes tissue necrosis, compartment syndrome, & loss of function
May need surgery if complications lead to nerve damage
NURSING ACTIONS
Stop the infusion & disconnect tubing
Aspirate flush to pull out the med
Notify provider
Give antidote per protocol
Elevate extremity
Types of Irritants
Potassium Chloride at low concentrations
Many IV antibiotics
Vesicants
Chemotherapy agents
Vasopressors
Promethazine, vancomycin
Concentrated solutions (ex: dextrose >12.5%, NaCl >3%)
Central Lines
Enters the lower part of SVC, near the cavoatrial junction.
IS STILL A VENOUS LINE (The SVC is a large vein)
ADVANTAGES
Lasts longer and more reliable than PIV
Draws blood samples w/o need for 2 IVs
Able to give vesicants, TPN, chemo, and hyperosmolar solutions
Can give KCl (potassium chloride) at faster rates (up to 20mEq/hr)
Can measure Central Venous Pressure (CVP) → Gives info on fluid status
Long-term venous access
DISADVANTAGES
CLABSI → Monitor for fever, chills, redness, drainage at site
Sepsis
Due to direct connection of catheter to the heart
Only use central lines when necessary. Use PIV if possible to prevent increased CLABSI risk.
Thrombosis (DVT) → Monitor for arm, neck, or face swelling, and pain
Ways to Prevent CLASBI
Hand Hygiene
Scrubbing the hub
Dressing change
Skin wipes
Types of Central Line
Non-tunneled
Tunneled
Implanted ports
Open Tips
Valve Tips
Tunneled Central Line
Travels under the skin before reaching the SVC.
Makes it safer to prevent CLASBI in long term use.
EX: Hickman
Non-tunneled Central Line
Enters directly into SVC
EX: central venous catheter, PICC lines
Implanted ports
“Port-a-cath”. Placed completely under the skin
Uses a special type of needle to inject meds
WHEN ACCESSING
Clean site using sterility
Assess site for redness, pain, etc
Put needles in & flush w/NS
WHEN DE-ACCESSING
Flush w/ Heparin to maintain patency
Should be routinely flushed & locked once per month even without use.

EJ Line
Is a peripheral line in the neck, NOT a central line
PIV enter small veins
Peripherally Inserted Central Catheter (PICC)
Placed in a large vein of arm and then enters SVC, has two access ports to provide connection for fluids and meds.
Can used same arm w/PICC to take blood pressure
Central vs Peripheral IVs
Central → Inserted into large veins and into SVC
Peripheral → Inserted into small veins
PICC lines vs Midlines
PICC lines are inserted at the arm and the cather extends into the SVC. Midlines is also inserted at the arm, but the catether stops at the armpit and does not enter the SVC
Can also give TPN in PICC but not midlines
Power Injectable Devices
Power PICC/ Power Port → Used for contrast dye for CT test & etc
What needs to be done when IVs are placed?
Must confirm tip position via chest X-ray
Document the date, catheter type, number of lumens, length, site, tip confirmation, and sign with initials.
Complications of Central Line Insertion
Arterial puncture, bleeding, or hematoma
Pneumothorax (especially with subclavian & jugular lines due to proximity to lungs)
Air embolism (Pt will have sudden SOB, chest pain, and hypotension. Make sure catheter is clamped, turn pt to the left, place Pt in Tredelanburg, and give O2)
Catheter malposition
Catheter shears off, causing catheter embolism
What does a correct PICC dressing look like?
Clean, dry, & intact
Labeled w/ date & times
Visible insertion site
How to Remove Central Lines
Implanted Ports → Surgically removed
PICC & non-tunneled CVC → Removed by trained RNs per policy
Place pt supine or in Trendelenburg
Have patient perform Valsalva → Hold breath or hum as catheter is removed. Helps raise chest pressure to prevent air from being pulled in, reducing the risk of air embolisms.
Apply pressure until bleeding stops, then apply an air-occlusive dressing for 24hrs
Keep patient supine for 30 mins
Make sure the removed catheter tip is intact and matches documented length.
Parenteral Nutrition (PN)
Nutrients give via IV that bypasses the GI tract
Contains dextrose, amino acids, lipids, electrolytes, vitamins, & water
TYPES
Total Parenteral Nutrition (TPN)
Peripheral Parenteral Nutrition (PPN)
TPN
Meets full nutritional needs. Highly concentrated, so it is requires a central line (where blood flow is higher and dilutes TPN faster)
Access: Central Line
Osmolarity: HYPERtonic, 900 mOsm/L and above
Dextrose Concentration: 15-25% or higher
Duration: Long-term use
Nutrition: Can meet full nutritional needs in a small volume
Main Risks: CLASBI (due to central line use), metabolic complications, refeeding (due to Hx of malabsorption)
PPN
Lower-concentration formula through a peripheral vein. Used short-term or supplementally
Access: Peripheral IV in a large vein
Osmolarity: 900 mOsm/L or less
Dextrose: Less than 10%
Duration: Short-term (less than 2 weeks)
Nutrition: Often partial, requires large volumes
Main Risks: Phlebitis, infiltration, fluid overload
When is parenteral nutrition used?
It is used only when the GI tract cannot be safely used. If the gut is working, use it. Enteral nutrition (feeding tube into GI tract) is safer and better for the GI system. Save PN for those who really need it
When is PN most commonly used?
Bowel obstructions → Mechanical blockage of GI tract
Prolonged ileus → Decreased GI motility
Short Bowel Syndrome → Not enough absorptive bowel to meet nutritional needs
High-output fistula → Not receiving nutrients via food; just increases output
Severe pancreatitis → Given when enteral feeding is not tolerated
Severe Malabsorption → Intractable vomiting or diarrhea; severe GI toxicity
What is the main energy source in parenteral nutrients?
Dextrose. It contains glucose which is the biggest driver of energy
3.4 kcal per gram
2 in 1 Formulations
Includes Dextrose & Amino Acids. Hung for MAX 24 hrs; needs tubing changed every 24 hours.
Should be a clear to slightly yellow color
Lipids are given separately from bag
3 in 1 Formulations (TNA)
Contains Dextrose, Amino acids, & Lipids. Hung for MAX 24 hours; tubing is changed every 24 hours
Discard any PN that is still hanging if time limit is reached, even if volume remains, to prevent bacterial growth.
Should be a uniform milky white
Discard if there is separation or oil droplets
Hanging PN (like med admin)
Verify → Check bag with MAR, double-check pt allergies
Inspect → 2-in-1 should be clear, 3-in-1 should be white
Warm PN
Prepare → Use aseptic technique, new tubing & filter, scrub hub before connection.
Connect to correct lumen
Why is a filter used in PN?
It traps particles and large fat droplets before it reaches the patient.
If filter is clogged, DO NOT remove clogs. Replace it and notify pharmacy
Lipid Emulsion
Hung for max 12 hours, tubing is changed every 12 hours
Has risk of growing bacteria faster than in a mixed bag.
Hypoglycemia Risk in PNs
Assess Blood sugar in the first 24-48 hours of PN
If the bag is interrupted/delayed, hang 10% dextrose at the same rate to prevent hypoglycemic risk (NEVER speed up PN rate to “catch up”
When stopping PN, taper off. Check glucose 30-60 mins after stopping
Monitoring Patients on PN
Blood glucose (q4-6h when starting)
Weight (same scale & time)
Record I&Os
Vitals & temp q4h
Monitors electrolytes, BUN, creatinine, Mg, & P
Monitor triglycerides & LFTs
Monitor Line site & dressing every shift
What is the most common metabolic complication?
Hyperglycemia.
Is caused by dextrose load stress, infection, steroid use, and diabetes
Treated with insulin and reduced dextrose
How does hypoglycemia occur in PN use
Caused by sudden interruption or delay to PN.
Signs → Shakiness, sweating, tachycardia, confusion
Prevention → Hang DW10 if PN is interrupted and taper instead of abruptly stopping PN.
Refeeding Syndrom
Occurs when feeding restarts after starvation. Insulin drives phosphorus, potassium, and magnesium into cells, so serum levels drop
NURSING ACTION
Monitor for drops in phosphorus, potassium, or magnesium q12h within first 5 days; fluid retention, arrhythmias, resp failure, and confusion
PREVENTION
start low with PN (only 10-20 kcal/kg/day) and slowly advance.
Give thiamine 100 mg before feeding everyday for 5-7 days
Correct electrolytes
MOST AT RISK
Low MBI
Significant weight loss
Little to no intake fro 5-7 days
Alc use disorder
Eating disorders
Signs of CLABSI
Fever
Chills
Rise in WBC
Glucose is harder to manage
Redness or drainage at site
Does TPN or PPN have a higher risk for phlebitis and infiltration?
PPN because it is peripherally administered.
Should assess the site often and restart at the first sign of problems.
Complications to PPN
Fluid overload (weight gain of more than 1kg per day)
Electrolyte imbalance
Hypertriglyceridemia
PN-associated liver disease (elevated liver enzymes & cholestasis from long-term PN)
RBC storage
up to 42 days refrigerated at 1-6c
Unused blood must be returned to blood bank
Platelet storage
Lasts 5 days at room temp. IS NEVER REFRIDGERATED

Expected Response: INR, PT, and aPTT decrease to normal
Key Points: Must be ABO-compatible; use within 24 hours of thawing
Which blood product has the highest risk for bacterial contamination?
Platelets due to being at room temperature. Has the highest risk for bacterial contamination and sepsis.
Blood Transfusion Verification & Administeration
Must obtain consent for each new situation
Must verify type & cross match (ABO & Rh factor), want a negative result
Must use Y-tubing that is 18-20 gauge, prime only with 0.9% NaCl, never run blood with meds or other fluids at the same time.
Must start blood infusion with 30 mins of receiving from blood bank
Must complete infusion within 4 hours of spiking the bag
Must assess baseline vital signs before administering blood
Stay with the patient for the first 15 mins and reassess vitals signs and ask about symptoms after 15 mins.
Then reassess vital signs every hour
After transfusion is complete, reassess vitals again and flush with normal saline.
What should a nurse do if a patient needs a blood transfusion but has only one IV that is running IV antibiotics and pain meds?
Call for a 2nd IV, give time sensitive pain meds and antibiotics first before transfusion.
What should a nurse do if a patient is called for an MRI but needs a transfusion?
Start the transfusion after the MRI because it is time sensitive or if the transfusion is already running, finish the transfusion before doing MRI.
Transfusion Reactions
Occurs when blood is not ABO and Rh compatible
SIGNS
Febrile (rise of >1.8F)
Give antipyretics (acetaminophen)
Allergy (urticaria (hives)pruritis, flushing, anaphylaxis)
Give antihistamines. Give fluids, epinephrine, & airway support if anaphylaxis
Feeling of impending doom

TRALI (lung injury) → will see sudden hypoxemia, pul edema within 6 hrs not caused by fluid overload
Give O2 & resp support
Sepsis (high fever, rigors, hypotension)
Direct COOMBS
Looks for antibodies stuck onto RBCs after a transfusion
Indirect COOMBS
Looks for antibodies in plasma inside the bloodstream before a transfusion
Nursing Actions for Blood Tranfusion Reactions
STOP the transfusion → Disconnect line, pull back to remove as much blood as possible
Keep vein open by hanging NS on NEW tubing
Assess patient → VS, symptoms, & recheck pt ID & blood label
Notify Provider & blood bank
Send blood back to blood bank
Treat and document
Liver Function
Helps to breakdown hormones & drugs, filters waste (converts ammonia to urea), and makes bile.
IF damage to liver → Will have jaundice (due to inability to remove bilirubin from bloodstream), have increased ammonia leading to confusion and change in LOC, and causes decrease clotting factors, increasing risk for bleeding
Liver Function Tests (LFTs)
ALT & AST
ALT
Measures amount of alanine aminotransferase (a type of liver enzyme) inside liver cells
Normal range: 7-55 u/L
Increases in liver damage
AST
Measures amount of aspartate aminotransferase (a type of liver enzyme) in liver cells.
Normal range: 10-40 u/L
Increases in liver injury, indicates damage due to alcohol
Bilirubin
Normal: 0.1-1.2
Jaundice occurs when >2-3mg/dL
Ammonia
Normal range: 15-45 u/dL
Increases in advanced liver disease, indicates encephalopathy
Hepatitis
Inflammation of the liver caused by viral infections (Type A,B, C, & D), alcohol, drugs, and autoimmune disease
Acute = <6months , Chronic = >6 months
Pathophysiology
Virus damages hepatocytes, causing impaired bile flow, clotting, glucose regulation, protein metabolism, & detoxification
If acute, hepatic cells will regenerate and usually make a full recovery
If chronic, will have ongoing hepatocyte destruction leading to fibrosis, then cirrhosis, then liver failure.
SYMPTOMS
Will have systemic immune complexes → Rashes, arthritis, fever, vasculitis (inflammation of blood vessels), glomerulonephritis
Acute Hepatitis Symptoms
Pts are usually asymptomatic
TRIAD → Jaundice, dark (cola-colored) urine, clay-colored stool
Pruritis
RUQ tenderness
Hepatomegaly
Chronic Hepatitis Symptoms
Anemia
Easy bruising or bleeding
Spider angiomas (spider-like dilations of blood vessels)
Caused by excess estrogen that is not broken down by live due to damage
palmar erythema
!! Chronic can progress to cirrhosis, portal hypertension, and liver failure
Hepatitis A
Transmission: Fecal-oral (via contaminated food or water). IS ONLY ACUTE
S&S: Can be asymptomatic, flu-like symptoms, may have Triad symptoms (jaundice, dark colored urine, and clay colored stool)
Treatment: Supportive care only, usually resolves on its own
Prevention: 2 dose vaccine series
Prophylaxis: Hep A vaccine or immunoglobulin after 2 weeks if exposure
Outcomes: usually a full recovery, no carrier state or chronic hepatitis
Hepatitis B
Transmission: Blood & body fluids (sexual, perinatal, shared needles). Can be acute or chronic
S&S: Can be asymptomatic. May have rashes or arthralgia (joint pain)
Treatment: If acute: supportive care, if chronic: oral antivirals (-vir meds)
Prevention: 2- or 3-dose vaccine series
Prophylaxis: HBIG & hep B vaccine within 24 hours of exposure
Outcomes: May be severe; carrier state possible. Increased risk for chronic hepatitis, cirrhosis, and liver cancer.
Hepatitis C
Transmission: Blood-borne (usually via injection drug use/sharing needles).
S&S: Usually asymptomatic or mild
Treatment: Oral direct-acting antivirals for 8-12 weeks
Prevention: No vaccine (only screenings in all adults at least once)
Prophylaxis: No post-exposure prophylaxis, only follow-up testing and treatment is infected
Outcomes: Chronic infection, increased risk of cirrohsis & liver cancer. Is curable with antivirals
Hep C = Chronic
Cirrhosis
End-stage chronic liver disease develops over years to decades. Is non-reversible but has treatment
Disorganized regeneration of liver cells causes fibrosis & nodules
Causes distorted vessels that impede blood flow, causing portal hypertension.
HTN leads to hypoxia & poor cell nutrition, leading to decreased liver function
NURSING ACTION: Give PPI’s, electrolyte replacement, & vit K (for clotting factors)
CAUSES
Chronic hepatitis (B & C)
Alcohol-associated liver disease
MASLD (metabolic dysfunction-associated steatotic liver disease)
Hemochromatosis
MANIFESTATIONS
If early, very few symptoms → Fatigue, enlarged liver (hepatomegaly)
Other body systems will compensate for liver, so labs seem normal
If late, other systems can no longer compensate for the liver (decompensated) → will see liver failure & portal hypertension
Jaundice
Ascites
Peripheral edema
Liver becomes small & nodular
Skin → spider angiomas, palmar erythema, pruritus
Blood → anemia, leukopenia, increased bleeding risk
Neuro → encephalopathy, peripheral neuropathy
DIAGNOSTICS

US, CT, & MRI to visual liver size, nodules, & ascities
Liver biopsy: Gives a definitive diagnosis
Endoscopy: Screens for varices
COMPLICATIONS
Portal hypertension → increased venous pressure in portal vein
Esophageal & gastric varices (vessel dilations)
Periperal edema
Abdominal ascites → can become infected & lead to bacterial gastritis
Hepatic encephalopathy
Nursing Interventions for Varices & Bleeding
Prevent bleeding → Do screening endoscopy, give non-selective beta-blockers (-lols), avoid alc & NSAIDs
Do Balloon tamponade to stop bleeding; do TIPS if bleeding persists
Do Band ligation for varices (pinches dilated vessel with band)
Give vit K & platelets as ordered to decrease bleeding risk
Monitor INR, platelets, H&H, hematemesis, & melena
Ascities
A complication of cirrohosis that occurs when portal hypertension causes protein to shift into lymph space, changing the osmotic pressure, and causes fluid to leak into peritonial cavity (3rd spacing)
Hypoalbuminemia (low albumin): Decreases colloid oncotic pressure, causing fluid to shift out of vessels
Hyperaldosteronism (high albumin): Increased Na reabsorption leads to water retention
TREATMENT
Paracentesis (uses needle to remove fluid)
Give IV albumin if >5 L of fluid is removed
TIPS (transjugular intraheptaic portosystemic shunt)
Procedure that shunts blood from portal vein directly to hepatic vein to lower portal blood pressure.
Allows albumin to bypass liver
Used for recurrent variceal bleeding or ascites
RISK: Increases risk for infection and worsening encephalopathy.
