5
Q
when does preoperative assessment occur
A

6
Q
what is the purpose of the preoperative assessment
A
- obtain health info
- determine expectations
- provide and clarify info on procedure
- assess emotional state and readiness
- begin some postoperative teaching
- current medications
7
Q
what are the 9 goals of nursing assessment
A
- determine psychological status to reinforce coping strategies
- **establish baseline data
- identify medications and herbs taken that may affect surgical outcome

- identify any psychosocial needs of the client
- ensure all preoperative consultations are complete and communicate mobility/sensory deficits to the team
8
Q
psychosocial assessment of factors that can influence surgery
A
- excessive stress
- age, past experience, current health, socioeconomic status
- communication is key for lowering stress
- identify stressors
9
Q
what can anxiety do, what interventions can we do
A
- can impair cognition, deicison-making, and coping abilities
- can arise from lack of knowledge, unrealistic expectations, conflict interventions and religious/cultural beliefs
interventions:

Q
malignant hyperthermia**
A
- inherited genetic mutation

Q
which allergies should an RN be aware of in preop
A
- drug and non-drug
- latex allergy: screen for risk factors
- history of reactions suggesting latex allergy
13
Q
what is the CVS considerations b4 surgery that should be documented
A
- baseline VS recorded
- lab reports
- ECG, cardiac ultrasound
- use of cardiac drugs, presence of pacemaker
14
Q
What should be considered from the respiratory system in preop
A
- history of dyspnea, coughing, or sputum

16
Q
What should be considered from the urinary system in preop
A
- history of urinary or renal disease
- renal function tests (Cr and BUN)
- report problems voiding
- renal dysfunction can contribute to: electrolyte/fluid imbalance, increased risk for infection, impaired wound healing, etc
17
Q
What should be considered from the hepatic system in preop
A
- consider presence of liver disease if there is a history of: jaundice, hepatitis, alcohol abuse, cirrhosis
18
Q
What should be considered from the integumentary system in preop

- recognizing potential mobility restrictions postoperatively
19
Q
What should be considered from the musculoskeletal system in preop
A
- identify any MSK issues: arthritis, chronic back pain

- bring mobility aids to surgery
- report problems affecting neck or spine
20
Q
What should be considered from the endocrine system in preop
A
- diabetes
- risk for hyper/hypoglycemia/ketosis
- CVS alterations
- delayed wound healing and infection
- baseline capillary blood glucose preop
- clarify if usual dose of insulin should be given - thyroid dysfunction
- hyper/hypothyroidism are surgical risks due to elevated metabolic rate
21
Q
What should be considered from the immune system in preop
A
- pt’s w a history of compromised immune sys or use of immunosuppressive drugs can have:
1. delayed wound healing
2. increased risk for infection
22
Q
What should be considered from the fluid/electrolyte imbalance in preop
A
- vomiting, diarrhea, or difficulty swallowing
- identify drugs that alter status (diuretics)
- evaluate serum electrolyte levels
- NPO status (additional fluid/electrolytes prior to surgery if dehydration occurs
23
Q
What should be considered from the nutritional status/GI system in preop
A
- underweight (provide extra padding to prevent pressure ulcers)
- obesity (increased risk for cardiac and pulmonary complications)
- GI sys
24
what are some elective surgery preoperative teaching
teaching occurs in pre-admission clinic, same-day admission unit and inpatient unit

what are some emergency surgery preoperative teaching
- teaching occurs in ER or inpatient unit if there is time
