med surg Ch. 16
refers to a pt admitted to hospital
(Ambulatory) Pt who goes to the surgical area the day of surgery and returns home the same day.
Performed to determine the origin and cause of a disorder or the cell type for cancer.
: breast biopsy, colonoscopy
Performed to resolve a health problem by repairing or removing the cause.
: appendectomy, hysterectomy
Performed to improve a pts functonal ability.
: Total knee replacement, hip replacement
To relieve symptoms of a disease process, but does not cure.
: Colostomy, nerve root resection, tumor rebulking
Planned for correction of a nonacute problem.
: cataract removal, hernia repair, total joint replacement
Requires prompt intervention; may be life threatening if tx is delayed more than 24-48 hr.
: Intestinal or bladder obstruction, kidney or ureteral stones, bone fx, eye injury
Requires immediate intervention because of life-threatening consequences.
: Gunshot or stab, severe bleeding, abdominal aortic aneurysm, compound fx, appendectomy
No significant risk; often done with local anesthesia
: Incision and drainage (I&D), Implantation of a venous access device (VAD), muscle biopsy
Greater risk; usually longer and more extensive than a minor procedure
: Mitral valve replacement, pancreas transplant, lymph node dissection
only the most overtly affected areas involved in the surgery
: simple/partial mastectomy
Extensive surgery beyond area obviously involved; directed at finding a root cause
: Radical prostatectomy, radical hysterectomy
Minimally invasive surgery (MIS)
Surgery performed in a body cavity or body area with endoscopy; can correct problems, remove organs, take tissue for biopsy, re-route blood vessels and drainage systems.
: Arthroscopy, tubal ligation, hysterectomy, lung lobectomy, caronary artery bypass, cholecystectomy
Carbon monoxide on oxygen-binding sites of the hemoglobin molecule, which decreases oxygen delivery to organs. (Comen in smokers)
collapse of alveoli; reduces gas exchange and causes intolerance of anesthesia (commen problem after general anesthesia)
Blood donation made by the pt a few weeks before surgery
Directed blood donation
Family or friends donate blood exclusively for their use.
# of serious problems
# of deaths
awakening during nighttime sleep because of a need to void
scant amt of urine
What is needed for wound healing and blood clotting?
K, Vit C and B
0.5-1.1 mg/dl or 44-97 umol/L
Blood urea nitrogen (BUN)
10-20 mg/dl or 2.1-7.1 mmol/L
Prothrombin time (pro time, PT)
11-12.5 sec, 85% to 100%, or 1:1.1 patient-control ratio
International normalized ratio (INR)
Partial thromboplastin time, activated (aPTT)
females 18-44: 12-16 g/dl or 117-155 g/L
Females 18-44: 35-45%
Which drugs are commonly allowed with a sip of water before surgery?
Drugs for cardiac disease, respiratory disease, seizures, and HTN.
What is the purpose of coughing?
to expel secretions, keep the lungs clear, allow full aeration, and prevent pneumonia and atelectasis
What is a common sign of a DVT?
Sudden swelling in one leg; the pt may feel a dull ache in the calf area that becomes worse with ambulation.
What are the benefits of mobility?
Stimulates int. motility, enhances lung expansion, mobilizes secretions, promotes venous return, prevents joint rigidity, and relieves pressure.
