Intra-operative precautions Psychological support

(before induction & when a patient is conscious) 1. Provides emotional support to PT 2. Stands near or touches patient during procedures & induction

Preoperative instructions to prevent postoperative complications

***One goal of preop nursing care is too educate the patient how to promote optimal lung expansion & resulting blood oxygenation after anesthesia. The patient assumes a sitting position to enhance lung expansion***

Pre-Operative Instructions

***The Goal of the preoperative period is for the patient to be as healthy as possible, every attempt is made to assess for & address risk factors that may contribute to postop complications & delay recovery***

Hypotonic Fluids Memory**HYPO- HIPPO (tonic) (swell)

- A solution where the fluid goes into cell, the cell swells -solutions containing a lower concentration of salt than ICF -diluted fluids- less salts- more water

Lower osmolarity

-less concentrated -replace fluid inside cell- cellular dehydration

Higher Osmolarity

-more concentrated -pulling fluids out of the cell from (ICF) to ECF- where there is high salt- water gets pulled their to maintain homeostasis

Leg Exercises

1) Lie in a semi-Fowler position and perform the following simple exercises to improve circulation 2) Bend your knee and raise your foot-hold it for a few seconds, then extend the leg and lower it to the bed 3) Do this five times with one leg and then repeat with the other leg 4) Trace circles with the feet by bending them down, in toward each other, up, and then out 5) Repeat these movements five times

Getting out of Bed
