24

Local anesthesia
25
In a patient with spinal anesthesia, what do you have to watch especially for?
Respiratory paralysis, drop in blood pressure, and loss of sensation in fingers and toes

How can respiratory paralysis be prevented in patients with spinal anesthesia?
Elevation of the upper body

Vasodilation associated with the block
28

29
What is the nurse's responsibilities for a patient in conscious sedation?
Monitor and check the airway, LOC, O2 saturation and ECG
30
What increases the risks of anesthesia?
Fluid and electrolyte imbalance, respiratory complications, cardiovascular disease, obesity, diabetes, renal disease, and sleep apnea
31
Why does sleep apnea increase the risk of anesthesia?
Can't metabolize anesthesia well
32
Why does obesity increase the risk of anesthesia?
Patients are often malnourished and the meds are desponsited in the fatty tissue
33
What happens during surgery to mess up fluid and electrolyte balances?
Increase in ADH and aldosterone, stress hormones are released, and platelet aggregation increases
34
Why are malnourished patients at a higher risk of surgical complications?
Negative nitrogen balance can cause impaired healing
35
Why does diabetes increase surgical risk for complication?
Increased susceptibility to infection, impaired wound healing
36
Why do respiratory problems increase the risk for surgical complications?
Difficulty clearing secretions, reduces means to compensate for acid/base alterations
37
Why does liver disease increase the risk for surgical complications?
Alters drug metabolism, impairs wound healing, impaired clotting times
38
What preoperative diagnostic tests should be run on patients?
CBC with diff, coagulation studies, BUN, creatinine, ECG, pulmonary function tests, and type and cross match
39
What is the duty of the physician in obtaining informed consent?
Explain the nature and reason for the surgery, who will be performing it, all available options and risks
40
What is the nurse's responsibility in obtaining informed consent?
Witness the explanation and the signature
41
Minimally, what must be verified by all members of the surgical team?
Patient's identity, correct site and side, correct patient position, and agreement on the proposed procedure
42
Why are patients made NPO before surgical procedures?
To ensure that the stomach contains a limited volume of gastric secretions to decrease the risk of aspiration
43
Which types of drugs are commonly allowed on the day of a surgical procedure, despite NPO status?
Drugs for cardiac disease, respiratory disease, seizures, and hypertension
44
What teachings should a nurse do for the preoperative patient?
Diaphragmatic breathing, splinting, leg exercises, turning and mobility, equipment, medications
45
How can the nurse monitor fluid and electrolyte balance in a preoperative patient?
Weigh them
46
What is the most important way to prevent surgical infection?
Antibiotics before surgery
47
What must be in the patient's chart before surgery?

48
When do the 3 surgical time outs occur?
Before anesthesia, before surgery starts, and before the patient leaves the OR
49
Registered nurses who coordinate, oversee, and are involved in the patient's nursing care in the OR
Circulating nurses
50
Prepares supplies and equipment on the sterile field, maintains safety, does a sharps count
Scrub nurse
51
When are counts of the equipment performed?
Before the procedure, during the procedure as items are added, at the closure of the first layer of the surgical wound, and immediately before the complete skin closure
52
Which members of the surgical team are not scrubbed in?
Anesthesia provider and the circulating nurse
