of South Dakota Department of Nursing Abstract The Author has completed a case study on a patient on a Medical Surgical floor as observed during a clinical rotation. A reader will find complete overview of a woman experiencing primary peritoneal cancer with metastasis who is under the care of hospice. Following a referral from hospice for a thoracentesis the patient is hospitalized. The reader will understand priority nursing diagnosis for a person with this condition. Case Study

Does diagnostic ultrasound have a role in emergency medicine? Introduction Emergency medicine (EM) is the medical specialty involving care for undifferentiated and unscheduled patients with illnesses or injuries requiring immediate medical attention. The specialty is not limited to the emergency department and may be practiced in numerous other settings including urgent care clinics‚ ambulances‚ at disaster sites‚ and even through telecommunications technology‚ known as telemedicine.

EXERCISE 1A: Diffusion The materials include a 30-cm piece of 2.5-cm dialysis tubing‚ 15-mL of the 15% glucose/1% starch solution‚ 250-mL beaker‚ distilled water‚ 4-mL Lugol’s solution‚ and string. EXERCISE 1B: Osmosis The materials used include 25-mL of these solutions: distilled water‚ 0.2M sucrose‚ 0.4M sucrose‚ 0.6M sucrose‚ 0.8M sucrose‚ and 1.0M sucrose‚ scissors‚ string‚ a balance‚ six 250-mL cups‚ and six 30cm strips of dialysis tubing.

hypothesis that solutions have a lower freezing point than pure water. The second property observed was osmosis pressure. This experiment used a 6 inch piece of dialysis tubing that was filled 2/3 full with light Karo syrup and tied off. Then it was completely submerged in a large glass bowl of room temperature distilled water. The dialysis tubing acts as a semi-permeable barrier and water passed through to inside the tube and over the next several hours‚ this act caused the tube to swell. Osmosis

The dialysis treatments or transplanted kidney will take over some of the work of your diseased kidneys and remove wastes and extra fluid from your body. This will improve many of your symptoms. Transplantation has many advantages. It eliminates the need for dialysis and helps patients enjoy a life filled with more freedom‚ energy and productivity. Although most patients are on

Two weeks later‚ the patient again presented to the same outside hospital where she was still found to be bacteremic and her dialysis catheter was exchanged for a second time in which a left subclavian dialysis catheter was placed. After placement of the dialysis catheter‚ the patient had three incomplete dialysis sessions that were cut short due to patients complaint of chills and shortness

This experiment can also refer to hypo‚ hyper and isotonic due to the two solutions being separated by the dialysis tubing (which acts as a semipermeable membrane) and diffusing from
