39
is a controlled
environment designed to maximize
infection control and provide a seamless
flow of patients, personnel, and operative
instruments, equipment, and supplies. The
suite is divided into three distinct areas:
unrestricted, semirestricted, and restricted
surgical suite
40
Designed to maintain surgical asepsis
Divided into unrestricted, semirestricted, and
restricted zones
Specifics of surgical attire are recommended
by Association of PeriOperative Registered
Nurses (AORN)
Equipment is sterile
Airborne bacteria controlled by air flow

oliguria, and anuria
* Hypertension ( increase in BP)
* Dysrhthmias
* DVT
* Pulmonary embolism
* Syncope - Fainting
62

* Presence of an endotracheal tube
* Polypharmacy
* Dehydration and malnutrition
* State of anxiety before surgery
63
what does the complete pain assessment consist of>
Location
* Intensity, assessed using a reliable, valid pain assessment tool
(e.g., verbal descriptor, numeric rating, or visual analogue)
* Quality (e.g., neuropathic pain may be described as “burning”
or “shooting”)
* Factors that relieve and aggravate
* Effect of pain on function
* Comfort–function goal (e.g., for the postoperative patient, link
pain control to the ability to deep-breathe, turn, or ambulate)
64
what are the GI problems?
constipation and diarrhea
N/V
aspiration
wound dehiscence
increase intracranial pressure
increased cardiovascular demand
flatus
ileus
paralytic ileus
65
what are the potential alterations in urinary function?
* Decreased urinary output
* Urinary Retention
* Impaired sphincter control
66
what are the potential integumentary complications>
Surgical site infections ( SSIs)
SSIs are caused by :
* Introduction of endogenous bacteria (from the patient) into the
wound
* Introduction of exogenous contamination (from the surgical
environment) into the wound
* Inability of the individual to resist infection due to reduced immune
capacity (disease, malnutrition, medication) or other factors
Indicators as follows:
* Purulent discharge
* Isolation of organisms from wound fluid or tissue
* Pain, tenderness, local edema, warmth
* Physician or health care team member diagnosis
67
what does a wound assessment consist of>
Appearance: Note the colour of wound, bruising, redness, and
approximation of the incision.
* Size: Note the length, width, depth and shape of the wound
and any signs of the wound opening (i.e., dehiscence or
evisceration).
* Exudate: Check the wound for exudate type (e.g., watery,
purulent), odour, and amount. A small amount of serous
drainage is common, and it changes from sanguineous (red) to
serosanguineous (pink) to serous (clear yellow). Draining will
decrease over time.
* Edema: Excessive swelling may indicate wound complications.
* Pain: Sudden onset or persistent severe incisional pain may
indicate infection, hemorrhage, or hematoma.
* Drains: Note the placement and security of drain or tube.
Check the collection device; empty as required and document.
