Exam 1 Chapter 5 Flashcards
surgical classifications
diagnostic (eg. biopsy, exploratory laparotomy)
curative (eg. excision of a tumor or an inflamed appendix)
reparative (eg.multiple wound repair)
reconstructive or cosmetic (eg. mammoplasty or a facelift)
palliative (eg. to relieve pain or correct a problem-gastrostomy tube)
Emergent surgery
patient requires immediate attention; disorder may be life-threatening. without delay. Eg: severe bleeding bladder or intestinal obstruction fractured skull gunshot or stab wounds extensive burns.
Urgent surgery
within 24-30 hours
Eg:
acute gallbladder infection
kidney or ureteral stones
Required surgery
patient needs to have surgery plan within a few weeks or months Eg: prostatic hyperplasia without bladder obstruction thyroid disorders cataracts
Elective surgery
patient should have surgery failure to have surgery not catastrophic Eg: Repair of scars simple hernia vaginal repair
Optional surgery
decision rests with patient
Eg:
cosmetic surgery
surgical intervention should be tailored to?
patient’s symptoms
overall functional
health status
predicted benefit of the intervention
Elderly people frequently do not report symptoms because?
fear of serious illness.
acceptance of symptoms as part of the aging process.
Protective measures for the elderly patients
adequate padding for tender areas.
moving patient slowly
protecting bony prominences
Surgical risk for the elderly patients
decrease ability to respond to stress.
increase vulnerability to changes in circulating volume and blood O2 levels.
pulmonary edema (excessive or rapid IV solutions).
increase susceptibility to hypothermia.
skin complications.
airway occlusion
surgical risk for the obese patient
dehiscence
wound infections.
shallow respirations when supine=hypoventilation and pulmonary complications.
nursing management for the obese patient before surgery.
careful assessment of the cardiopulmonary status.
thorough wound assessments.
when does the preoperative phase begins and ends?
begins when the decision to proceed with surgical intervention is made, and ends with the transfer of the patient onto the OR table.
Nursing activities during the preoperative phase
base line evaluation of..
H and P (history and physical)
emotional assessment
previous anesthetic
identification of allergies or genetic issues.
ensuring necessary labs have been done or will be performed.
arranging appropriate consultations
providing education about recovery from anesthesia and postoperative care.
what is the primary purpose of the informed consent process for surgical services?
To ensure patients, or their representative is provided information necessary to enable him or her to evaluate the proposed surgery before agreeing to it.
who obtains the informed consent?
it is the responsibility of the performing surgeon.
How should the nurse determined patient’s nutritional needs?
measurement of body mass index (BMI) and waist circumference.
Normal BMI
18.5-24.9
BMI of less than 18.5
underweight
great than 25 BMI
overweight
BMI greater than 30
obese
A waist circumference measurement of greater than 40 inches for men and 35 inches in women is associated with?
increased cardiac risk.
Nutrients important for wound healing.
protein Arginine (amino acid) carbohydrates and fats water Vitamin C, E, A, K, B complex magnesium copper zinc
Alcohol withdrawal syndrome or delirium tremens may be anticipated?
between 48 and 72 hours.
The patient with diabetes undergoing surgery is at risk for?
hypoglycemia = during anesthesia or postoperatively from inadequate carbohydrates or excessive administration of insulin. hyperglycemia= stress of surgery because it triggers increased release of catecholamines .
surgical patients with type 1 diabetes are at risk for developing?
ketoacidosis : absence or inadequate amount of insulin. SxS: hyperglycemia ketosis dehydration electrolyte loss acidosis polydipsia polyuria acetone breath (fruity odor similar to overripe apples)
signs of adrenal insufficiency
hyponatremia hypoglycemia hyperkalemia weakness fatigue
patients with uncontrolled thyroid disorders (hyperthyroid) are at risk for?
thyrotoxicosis
patients with hypothyroid disorders are at risk for?
respiratory failure
Foods to determine latex allergies
bananas
avocados
kiwi
chestnuts
An important outcomes of the psychosocial assessment.
determination of the extent and role of the patient’s support network.
value and reliability of all available support systems.
level of functioning.
typical daily activities.
The effect of corticosteroids-Prednisone (Deltasone) with Anesthetics.
cardiovascular collapse if discontinued suddenly.
Tx: bolus of corticosteroid may be administered intravenously immediately before or after surgery.
Diuretics Hydrochlorothiazide (HydroDiuril) effect of interaction with Anesthetics.
may cause excessive respiratory depression resulting from associated electrolyte imbalance.
Phenothiazines Chlorpromazine (Thorazine) effect of interaction with anesthetics.
may increase the hypotensive of anesthetics.
Tranquilizers Diazepam (Valium) effect of interaction with anesthetics
may cause anxiety, tension, and seizures with withdrawn suddenly.
Insulin effect of interaction with anesthetics
IV insulin may need to be administered to keep the blood sugar within normal range.
Antibiotics Erythromycin (Ery-Tab) effect of interaction with anesthetics.
when combined with a curariform muscle relaxant, never transmission is interrupted .
apnea from respiratory paralysis may result.
Anticoagulants warfarin (Coumadin) effect of interaction with anesthetics.
increase the risk of bleeding.
Antiseizure medications
effect of interaction with anesthetics
IV administration may be needed to keep patient seizure free.
Monoamine Oxidase (MAO) Inhibitors Phenelzine sulfate (Nardil) effect of interaction with anesthetics.
may increase the hypotensive action.
Thyroid Hormone Levothyroxine sodium (Levothroid) effect of interaction with anesthetics.
IV administration may be needed during the postoperative period to maintain thyroid levels.
Central core disease (CCD)
genetic disorder presents in neonatal.
muscle weakness and hypotonia and mild facial weakness.
risk the risk of developing MH-malignant hyperthermia.
Duchenne muscular dystrophy and Becker dystrophy genetic disorders.
muscular dystrophies
risk for developing MH
Hyperkalemic periodic paralysis.
genetic disorder.
causes episodes of extreme muscle weakness.
associated with MH
King-Denborough syndrome
rare genetic disorder
musculoskeletal abnormalities.
associated with MH.
Preoperative Teaching
start in at the time of PAT
continues until patient arrives in OR
extends to discharge.
what is the goal of promoting coughing?
mobilize secretions, so they can be removed.
what may occur with infective coughing after surgery?
atelectasis (collapse of the alveoli)
pneumonia
