Pt 1 (Perioperative) Flashcards
What is the difference between an urgent and an emergent surgery
An emergency surgery must be done right away to save the patient’s life, whereas an urgent surgery is performed to prevent any additional problems like removing a gallbladder to prevent stones.
What is an ablative surgery
Removing a body part (amputation)
What is the difference between constructive and cosmetic surgery
Constructive is to restore function to a body part (repairing cleft palate), while cosmetic is to improve personal appearance
Describe a patient classified as ASA I
They are a normal healthy patient (nonsmoking, no-minimal alcohol use, etc.)
Describe a patient classified as ASA II
They have mild systemic disease (smoker, social alcohol drinker, pregnant, obese, controlled DM/HTN, mild lung disease)
Describe a patient classified as ASA III
They have severe systemic disease (uncontrolled DM/HTN, COPD, morbidly obese, hepatitis, alcohol abuse, pacemaker, moderate reduction of cardiac ejection fraction).
Describe a patient classified as ASA IV
They have severe systemic disease that is a constant threat to their life (Recent MI, CVA, TIA, ongoing cardiac ischemia or severe valve dysfunction, sepsis, disseminated intravascular coagulation, end-stage renal disease not having dialysis)
What is a moribund patient
A patient who is not expected to survive without the surgery
What does AORN stand for and what do they do
Association of periOperative Registered Nurses - they set standards and guidelines
What type of allergies would I want to know about before surgery
Latex or penicillin
If a patient is not sure if they are allergic to latex, what can you ask them
If they have a reaction when eating apples, avocados, bananas, celery, chestnuts, melons, papayas kiwis, raw potatoes/tomatoes? Or if they have a reaction when blowing up a balloon? If they have a reaction to the elastic in their underwear
Is it our job to explain the surgical procedure to the patient
No - that’s the physician’s job
What does ectomy stand for
Excision or removal of “appendectomy”
What does lysis stand for
Destruction of “electrolysis”
What does orrhaphy stand for
Repair or suture “Herniorrhaphy”
What does oscopy stand for
Looking into “Endoscopy”
What does ostomy stand for
Creation of opening into “Colostomy”
What does plasty stand for
Repair or reconstruction of “mammoplasty”
Besides allergies, what else do we want to screen for?
- Blood thinners
- Cultural (Jehovah witness)
- History of A-fib (can lead to blood clots)
What is a big plus of ambulatory surgeries, where you are going home the same day
You do not have to stay overnight in the hospital, where you are at risk for hospital acquired infections
Define local anesthesia
Usually given in your ambulatory setting, patient is healthy, they can tolerate the procedure, they’re not nervous, there is no sedation or loss of consciousness, they can go home the same day and eat and drink regularly.
What is regional anesthesia
It “blocks” a central nerve (spinal) or a group of nerves (ex plexus). That body region becomes numb. Usually for orthopedic procedures. If a patient has comorbidities, they will also probably get something to put them to sleep, so their HR doesn’t spike during surgery. Also given for C-sections. (you are still conscious)
What is a person at risk for when they receive a local anesthetic (from lidocaine)
Local anesthetic systemic toxicity (LAST)
What are early symptoms of LAST 5
- Ringing or whoosing in ears
- Confusion
- Metallic taste
- Oral numbness
- Dizziness
If left untreated, what can LAST lead to
Seizures, coma and dysrhythmias
What is the difference between a spinal and epidural anesthesia
A spinal anesthesia is injected into the cerebrospinal fluid, while an epidural is injected into the epidural space and does not enter the cerebrospinal fluid (you can’t feel anything, but you can still move (does not block motor, only blocks sensory) - versus spinal, where you can’t move or feel anything)
Is intubation required for sedation
In mild to moderate, the patient is usually breathing on their own. For Deep sedation, they may need to be intubated.
What can a patient be intubated with under general anesthesia
Laryngeal mask airway (LMA) or a trachea tube.
Why would a person be put under general anesthesia
- Surgery may be long
- Need muscles to be relaxed
- May be uncomfortable positions
- Ventilation may need to be controlled
- Patient refused local or regional techniques
- Uncooperative
What is a fat embolism (risk during surgery)
Where subcutaneous fat can travel into the bloodstream and into your lungs
What are normal albumin levels
3.4-5.4
What can a deficiency in albumin indicate
- Liver or kidney disease.
- Body is not absorbing enough protein.
What is our main goal in preop
- Provide baseline data
- Identify risk factors
What other goals do we want to accomplish in preop
- Prepare patient for surgery
- Patient teaching
- Complete our checklist
- Interprofessional communication
What if the patient believes that they are going to die in the surgery
Notify the provider right away - the strong emotional state may put stress on the surgery (surgery might be delayed due to this)
If a patient has had juice or milk to drink before surgery, what should you do
Call anesthesia to inform them
What is the total surgical period called
Perioperative care
When assessing the respiratory system, what things should we ask
- If they have had a cold or fever recently (if they have had an upper respiratory infection - surgery will probably be delayed)
- If they have used their inhaler recently - have them bring it with them to take a few puffs the morning of to help open up the airways.
- STOP BANG - for patients with sleep apnea, have them bring in their CPAP to use in the recovery room.
- Want to know if they smoke, smoking should be stopped 6 weeks prior to surgery.
- If they have COPD
If a patient has COPD, what are they at high risk for after surgery
- Hypoxemia (low oxygen in blood)
- Atelectasis (alveoli become deflated)
What do you want to assess for in the nervous system

- Is and Os
- If they look dehydrated
- Do they look emaciated
- How is their skin turgor
- Kidney disease
- Chronic UTIs
- Renal function test (labs)
- If a woman may be pregnant
Why is renal dysfunction scary for surgery
Renal dysfunction can lead to f&e imbalances, coagulopathies (blood doesn’t clot), increased risk for infection and impaired wound healing.
When assessing the hepatic (liver) system, what are we looking for 8
We are checking for signs of liver disease
- Are they itchy
- Do they have an altered mental status
- Do we see jaundice
- Ask about alcohol and tylenol
- History of hepatitis
- Obese - can indicate liver dysfunction
- Enlarged abdomen
- Perform a liver function test
Impaired hepatic function can cause what risks
Clotting abnormalities and adverse responses to drugs
What do we want to assess for the integumentary system
- If they have any present cuts, document, in case they think we gave them the cut after surgery or they get an infection
- Note any skin breakdown
- History of pressure sores - may need more padding
What do we assess for in musculoskeletal
- Assess any numbness/tingling
- If they have a history of arthritis
- Test ROM/strength
- Patients will usually be on muscle relaxants
What is one major concern we have for the endocrine system
If the patient is diabetic
If the patient is diabetic, what are we doing
Don’t have them take oral diabetic medication the morning of surgery, if they are on insulin - take half of the dose.
- Check their sugar before surgery and during.
What are we assessing for with fluid and electrolytes
If the patient has had any episodes that might impact F&E, like vomiting, diarrhea or completing a bowel prep.
- Check electrolyte levels before surgery
- Be careful with older adults, they are less adaptive and more prone to overhydration or dehydration
What if a patient has a BMI greater than 40
Notify the OR team so they can prep.
What if a patient is underweight
They may need more padding then usual
What assessments do we want to do for nutritional status
