The SBAR Approach for Effective Communication
SBAR is an acronym that correlates to:
Situation: Brief statement of the problem or issue being addressed
EX: Hello, Dr. Jones. This is Steve, the registered nurse caring for Ms. Sandra Williams in
Room 732 on South Wing. I am contacting you because she arrived from the post-anesthesia
care unit (PACU) and has not voided in more than 6 hours. Vitals will be here also
Background: Data related to the current situation
EX: She was admitted to the hospital this morning, and you performed a lumbar laminectomy
this morning for a herniated disc at L4–L5.Assessment: Summary of causes, significance, severity of situation
EX:Ms. Williams is complaining of inability to void. According to her operative reports, she
received 1,500 mL of IV fluid during the surgical procedure and in the PACU, and the
indwelling catheter was removed prior to transfer from the PACU 6 hours ago; at the time, she
had 800 mL of urine output. She has received an additional 250 mL of IV fluid since arriving on
the unit.
Recommendation: Specific actions needed to address the situation
EX: I recommend that an intermittent catheterization be performed at this time.

****In medical surgical nursing your biggest responsibility is to make sure your patient
understands an procedure and they understand their discharge teaching
****The nurse has to have empathy, be caring, and have compassion
Chapter 15
Use 18g for IV blood products
Always make sure you have consent for everything consent is your biggest responsibility
(Surgeon gets consent)
Make sure patient understands the procedure and everything that follows. Make sure that the patient
has no questions
(Nurses responsibility)
They need to know the doctors name
Informed Consent
Components include:
Consent for procedure itself
Name of surgeon to perform surgery
Reason intervention will benefit the patient
Alternative options to surgery
Consent for anesthesia
Consent to administer blood products
***Although obtaining consent is not the role of the nurse but that of the provider, it is the
nurse’s responsibility to ensure that the patient has all the information needed to make an
informed decision about the procedure being offered
Obtaining Consent
The role of the surgeon is to obtain consent for the procedure. The surgeon is solely responsible
for obtaining consent in the presence of the patient and one witness.
The role of the preoperative nurse is to clarify information and ensure patient understanding.
Nurses correct common misconceptions and ease concerns of the patient, family members, or
support persons
Advanced Directives
Defines patient’s wishes
Name a power of attorney
SurgeryCorrect patient
Correct procedure
Correct Surgical Site
*** Always remember my right may be your left and your left may be my right she make sure
your on the correct side
Always assess patients
Their medical history is important( always ask about bleeding problems)
Make sure patients has understanding of how to use assistant devices incase needed
Surgical and anesthesia history
Do you have poor healing, any pervious surgeries, negative responds to anesthesia, or any
allergies
***If allergies put on alert bracelet
Last oral intake
Guidelines dependent upon institution and population
Full stomach increases risk for aspiration
***A patient who has eaten within 8 hours is at risk of aspiration, the introduction of food particles into
the lungs through emesis
***According to recent guidelines for elective procedures, the patient may be advised to be NPO 6 to 8
hours for solid foods and 2 hours for clear fluids.
Physical preparations
Intravenous line
An IV line is inserted during the preoperative admission, typically for the purpose of the
administration of anesthesia and fluids during the surgery. An 18-gauge catheter is preferred
because this size is required for the administration of all blood products.
Bowel and bladder preparation
Patients receiving abdominal, intestinal, gynecological, or rectal surgery may be asked to
perform a bowel preparation. This may be done by use of an enema or gentle laxatives that the
patient self-administers at home the night before the procedure. The nurse should confirm and
document that this preparation has been performed. Patients scheduled for abdominal,
gynecological, or long procedures may also require the insertion of an indwelling catheter to
drain urine. This will keep the bladder empty during a procedure, preventing injury to the
bladder. It also allows the surgical team to monitor output in the operating room and PACU.
Skin preparation
Prior to surgery, skin preparation is done to help prevent infection at the surgical site. Patients
may be instructed to shower and wash with Betadine or hexachlorophene soap prior to
admission. A surgical shave may be necessary depending on the patient’s skin type and the
location of the incision. If a shave is appropriate, the nurse uses a sterile electric clipper. A razor
is not recommended because of the risk of infection caused by small nicks in the skin that may
occur with a razor.
Medications
Preoperative medications may be required. Patients with preoperative anxiety may be prescribed
a benzodiazepine such as midazolam HCl, diazepam, or lorazepam. Antiemetics such asmetoclopramide HCl or ondansetron HCl may be used preoperatively if a patient has a history of
nausea and vomiting due to anesthesia.
Medications
You need to know if the patient takes any medications or herbal medications
3’G’s Ginger. Ginkgo Biloba, Garlic
Taking anticoagulants
Priority assessments
Cardiovascular
Respiratory
Integumentary
Priority labs
CBC
PTT/INR
You want to try to prevent DVT (DVT Prophylaxis)- Sequential compression devices
Prevent Pneumonia- Incentive Spirometer(Inhale than breathe out) use at least 10 in an hour
Also do deep breathing and coughing
Always remove jewelry and prosthetics before surgery
****Patient teaching is very important they should verbalize and demonstrate their
understanding
Chapter 16
Impatient- Require close monitoring and recovery more than 24 hours after completion
Same day- Require less than 24 hours of monitored recovery
Elective Surgery- The patient Chooses
Urgent Surgery- May not be up to the patient
***The patient has the right to deny any produce

Age related changes
Senescence – Normal age-related changes in organ systems
*Sclerosis – Hardening of tissue due to fibrous tissue overgrowth
Stenosis – Narrowing or constricting of a passage or orifice
*Atrophy – Wasting away or decrease in the size of an organ
*Calcification – Calcium and calcium salts are deposited in abnormal locations, like blood
vessels
Risk factors Cardiovascular problems
Stoke
Hypertension
High cholesterol
Diabetes
Smoking
Obesity
Poor Diet
Physical activity
Common Illnesses
Pneumonia – Older adults at higher risk due to decrease in lung’s elastic recoil, weakened cough
reflex, weakened diaphragm strength, and impaired swallowing
Chronic obstructive pulmonary disease – Smoking is greatest risk factor
Dementia – Progressive cognitive decline that affects a person’s social and occupational
functioning
Depression – Difficult to diagnose in older adults and may include low energy levels, difficulty
sleeping, less appetite, aches and pains, difficulty remembering details
Parkinson’s disease – Degenerative condition primarily affecting movement, causing tremor,
rigidity, gait disturbance, and speech disturbance
Cerebrovascular accident – Stroke; vascular disease manifesting as paralysis, weakness, speech
and vision impairment
Episodic memory diminishes with age – Evident in tasks requiring learning and recall of items
that are not meaningful, for example, phone numbers
Free recall diminishes – The ability to recall unrelated words from a list decreasesWorking memory ability decreases – The ability to multitask successfully declines with aging,
along with reduced ability to process complex incoming information
Semantic memory maintained or may increase – Memory of facts and meanings and intellectual
ability are unchanged
Processing speed decreases – If speed is not crucial, information is retrieved as well as in
younger people
Increased risk of dehydration
General decline in bladder function and capacity.
Sexual dysfunction related to hormone decreases, organ atrophy, and decreased sexual fluids
Senses of taste and smell diminish, making food seem less appealing
Premature feelings of fullness leading to malnutrition
Constipation and impaction
Dentition/chewing limiting available foods
Dysphagia leading to aspiration or pocketing of food
***Delirium- Is a quick onset of confusion
***Dementia- Slow and progressive over time
Always ask about medications and what and when are they taking these meds
Polypharmacy- Taking any and everything not really knowing what it is
You want to protect them from abuse and watch for S&S
Ask about their living will and do they have an DNR
Medicaid- Medical coverage to low income families. The state and government share the cost
Medicare- Is very important to elderly. Is a federal program that provides health care to people
65+
Part A(Hospital Insurance) – Covers inpatient hospital stays
Part B(Medical insurance)- Covers doctors services
Part C- Private companies that cover what part A and B don’t
Part D(Prescription)- Covers medication cost
***Some parts some people can’t get
*** When you document you want to watch what you put in when it comes to Medicare
*** Always remember safety is a priority with elderly
***Everything decreases but blood pressure
Chapter 8
Intracellular fluid (ICF) – about two thirds by volume, contained in cells
Extracellular fluid (ECF) – consists of two major subdivisions
Plasma – the fluid portion of the blood
Interstitial fluid (IF) – fluid in spaces between cells
2500 ml/ day in so 2500ml/ day out
Whatever the patient takes in it needs to come outUrine output 1500mL / 30ml/hr
Osmosis-Low concentration to high concentration
Diffusion- High concentration to low concentration
Fluid Spacing
First spacing
normal distribution of fluids in the ICF & ECF compartments
Second spacing
abnormal accumulation of interstitial fluid as seen in edema
Third spacing
accumulation of fluid in portions of the body which is not easily exchanged with the rest of the
ECF
Regulates Water Balance
Hypothalamic
Pituitary
Release of ADH
Increase in plasma osmolality or decrease in blood volume will stimulate thirst and the
release of ADH
Signs and Symptoms of Diabetes
Polyuria: LOTS of urine 4L to 24 L per day
Polydipsia: body’s way of trying to keep water in the body….crave water/ice
Dry mucous membranes, dry skin, decrease skin tugor…very dehydrated
Urine diluted….low urinary specific gravity
Hypotension (due to the severe dehydration and remember ADH is responsible for
constricting blood vessels…here the vessel will be dilated which causes hypotension) Extreme fatigue and muscle pain/weakness
Hypernatremic (due to the concentrate sodium in the body from low water levels)
Solutions
Isotonic(NO CHANGE)
No change in the concentration of solute and water in the bloodstream
Osmosis neither moves water into the circulation nor pulls it out.
0.9 NACL ; LR; D5W (functions as hypotonic once glucose is metabolized)
Treatment for ECF deficits – expands ECF volume
Hypotonic(BIG CELLS)
Lower osmolality than blood serum
More water (relative to solute) is being infused than is already present in the vessel and inside
the cells.
Therefore, water moves into the cells
Indicated for hypernatremia and hyperosmolar conditions Replaces cellular fluid & provides free
water
Can cause cerebral edema and Hypotension from intravascular depletion
Contraindicated in edema and third spacing
0.45 NS (1/2 NS) , D5 .45
Hypertonic(SMALL CELLS)
Higher osmolality than blood serum
Osmosis pulls water out of the cells
Cell shrinkage
Increased osmolality of ECF - expands it
Indications: Hyponatremia
3% NACL, D10W, D50W
Plasma Volume Expanders
Stays in the intravascular compartment and increases oncotic pressure
Colloids
Protein solutions - albumin (5% or 25%)
Synthetic molecules - Dextran, Hespan (Hetastarch)
Whole blood or packed red blood cells [PRBCs]
**Indicated for fluid losses from ECF (hemorrhage or sepsis)
Edema(Swelling)2mm or less = +1
Slight pitting, No visible distortion, Disappears rapidly
2-4mm = +2
Somewhat deeper pit, No readably detectable distortion, Disappears in 10-15 seconds
4-6mm = +3
Pit is noticeably deep, May last more than 1 minute, Dependent extremity looks fuller and swollen (4-
6mm)
6-8mm = +4
Pit is very deep, Lasts as long as 2-5 minutes, Dependent extremity is grossly distorted (6-8mm)
