Hair Removal

Surgical Site Preparation:

Q

If beta blockers is held according to parameters….

A

physician, PA, APN reason must be documented

why: perioperative myocardial ischemia has been identified as the #1 risk factor for mortality after non-cardiac surgery
- attributed to the exaggerated sympathetic response leading to persistently elevated HR
- Has the potential to significantly reduce cardiac deaths for up to 2 years postoperatively

Anti-Anxiety Medications

A

Uses: sedatives to relax the patient (does not relieve pain) Benzos depress the CNS leading to sedation, skeletal muscle relaxation and anticonvulsant activity

  • raise be to stretcher height
  • assist client to locked stretcher
  • Secure safety strap or raise side rails
  • transport chart with client
82
Q

Why do we make pts NPO after midnight the night before surgery?

A
  • vomiting with anesthesia

- can’t protect airway, no gag reflex

83
Q

The morning of surgery, your pt tells you that he had his breakfast and drank his coffee after being ordered NPO.

What are you going to do?

A
  • Call the surgeon
  • Call anesthesia
  • Call OR
  • Reschedule & place back on NPO
  • signs everywhere
  • talk with family
  • wait to hear back from surgical team
84
Q

Intraoperative Care

A
  • from holding room into surgery and admission to the recovery room
  • very high risk area for the patient. High potential for errors, life threatening situations and complications are greatly increased.
