Long term steroid therapy cannot be abruptly stopped because?
Higher steroid levels are needed during stress.
Complications that a nurse would correctly explain to a patient can be prevented with early postoperative ambulation
Pneumonia can be prevented with lung expansion promoted by ambulation
The nurse is caring for a patient with a bowel resection. What would indicate that the patient's gastrointestinal tract is resuming normal function
- Presence of flatus
- It occurs with normal bowel functions
Bowel is not functioning when:
Firm abdomen & absent bowel sounds
After surgery, patient's urine is dark amber & concentrated? Why?
The sympathetic nervous system saves fluid in response to stress of surgery
The patient develops a low-grade fever 18 hours post-operarively & has diminished breath sounds. What should the nurse do to prevent complications?
- Encourage coughing & deep breathing
- -Ambulate patient as ordered
May be elective, urgent or emergency
Purpose: To preserve life, repair or remove body part
Purpose: To restore function, remove skin lesion & to correct deformities
May be major or minor. Make or confirm diagnosis
Ex: breast diagnosis
Usually major. Diseased body part removed.
Ex: Appendectomy, Amputation
To restore function to traumatized or malfunctioning tissue
Ex: Scar revision, plastic surgery
To replace organs or structures that are diseased
Ex: heart, kidney, liver & cornea
Influencing factors of surgery
- Age: old & young don't tolerate surgical procedures
- Physical condition: Pt's with chronic disease or health problems require longer recovery periods.
- Nutritional factors:
Vitamin B (Thiamine) is for
Vitamin C is for
Blocks central awareness centers in brains, Administered by IV, inhalation
-Loss of consciousness, sensation, skeletal muscle relax & reduction of reflex
Minimal, can move
Surface/ topical applied directly to skin & mucous membranes
Used in minor procedures like skin biopsy / suturing
Anesthesia in nerve trunk
Via lumbar puncture into subarachnoid space
-Protects the client, physician & the health care institution, legal document
-Description of the procedure /Treatment
-Name & qualification of person performing procedure
-Explanation of risks involved
-Explains alternatives/ possible effects of not having treatment
-Info. that patient has the right to refuse treatment
Consent forms are not legal if:
- client is considered a minor, confused, unconscious, sedated, mentally incompetent
- -consent in these instances may be given by parent/guardian
Height, weight, VS, general appearance, provides base line data
-status of skin
*Immunologic status:history of allergies, immunosuppression common with radiation & chemo therapy
*Abd status: Bowel sounds, size, shape, last BM
*Endocrine status: in uncontrolled diabetes, hazard in hypoglycemia from anesthesia
*Neurologic status: Mood, motor & sensory function, follows all commands
Pre-operative Physical Assessment
The edges of the wound are approximated with staples or sutures. Minimal scarring.
-occurs in a clean wound
1st intention (Primary)
The wound is left open & allowed to heal by inside/out. Scarring is usually big w/ longed healing.
-Large, irregular or infected wounds
-Pressure ulcers are or chronic wounds are treated this way.
2nd intention (Secondary)
An infected wound is left open until there is no evidence of infection & the wound is then surgically closed.
-Granulation tissue fills in for some wound healing & then edges are approximated
-Wider scarring occurs
3rd intention (tertiary)
White blood cells, dead & live bacteria, warm, reddened, & tender and may have drainage (pus).
place the patient in low fowlers position with flexed knees. Cover the wound w/ sterile dressings or towels moistened w/ warm sterile normal saline. -Notify Dr. immediately of surgical emergency.
-Apply gentle pressure over the wound
-Monitor VS for evidence of shock
-Prepare pt for immediate surgery
If dehiscence or evisceration occur:
Mostly clear portion of blood, large #s of RBC's
Composed of fluid & cells escaping from blood vessels
Caused by bacterial invasion
WHat kind of asepsis for dressing changes
Excessive blood loss wither internally or externally
-May occur from a slipped suture, clot or stress on operative site
-Assess for restlessness
Goal: stopping the bleeding, replacing the blood volume
-Intervention: Pressure dressing to bleeding
Partial or total disruption of wound layers
-Goal: prevention- good nutritional status promotes wound healing, aseptic technique
-If superficial, may only need steristrips
Spilling of viscera thru the incision
-Goal: good nutrition
-Interventions: Cover wound area w/ a saline soaked sterile towel
-DO NOT TRY TO PUSH ORGANS INSIDE
Provides a sinus tract
For bile drainage after a gall bladder
Decreases dead space by collecting drainage usually after abdominal surgery
Decreases dead space by collecting drainage usually w/ orthopedic surgery
Purpose: Inspect for healing & sign of infection
Advantages: absorbs drainage, protect the wound, used as pressure dressing, splint or immobilize the wound
Supplies: Cleansing agent, Dressing, Tape, / montgomery straps
-Cause: Decreased blood flow, decreased circulation to body part, decreased oxygen called ischemia
-Risk: bony prominents
Superficial layer (epidermis/dermis)
Damage or necrosis of subcutaneous tissue
Damage to muscle-bone
Chronic renal disease
For dehisced surgical incisions that resist healing, aids in healing the incision.
-Applies negative pressure to wound edges
Vac (vacuum assisted closure)
Removal by cutting
Suture of or repair
Formation of a permanent artificial opening
Incision or cutting into
Formation or repair
Not smoking increases the action of the lungs defense mechanisms & makes more hemogoblin available to carry oxygen during surgery.
Long term alcohol use causes nutritional & liver damage. It can create bleeding problems, fluid volume imbalances & drug metabolism alterations.
Collapse of the lung caused by hypoventilation or mucous obstruction preventing some alveoli from opening & being fully ventilated
Do this hourly while awake, sets of 5, for 24-48 hours postoperatively
Prevents atelectasis by increasing lung volume, alveoli expansion & venous return
-For elderly & people w/ respiration problems
-sit at 45 degrees
-Take 2 normal breaths
-Inhale until target is reached
-hold for 3-5 seconds
Perform 10 sets of breaths each hour
causes the patient to loose sensation, consciousness, & reflexes.
-Acts directly on the central nervous system
Blocks nerve impulses along the nerve where it is injected, resulting in the loss of sensation to a region of the body w/o the loss of consciousness
Local anesthesia (regional)
A localized collection of extravasated blood, usually clotted, in an organ, space or tissue
