JD, a 15-year-old boy, is severely burned while escaping from a building fire. The extensive burns include first- and second-degree burns covering much of his body and a local, full-thickness burn on his right forearm. He reaches the emergency department in severe pain and is treated with intravenous morphine in increasing quantities until he reports that the pain has subsided. This dose of morphine is then maintained. The next day, he has surgical debridement of his burn wounds and a skin graft to his right forearm. During the operation, an anesthesiologist provides a continuous intravenous infusion of remifentanil, with a bolus dose of morphine added near the end of the operation. At the end of the operation, and for 4 days thereafter, JD receives intravenous morphine through a patient-controlled analgesia device. As the burns heal, the morphine dose is tapered and eventually replaced with an oral oxycodone/acetaminophen com- bination tablet. Three months later, JD reports severe loss of sensation to touch in the area of the skin graft. He also describes a persistent tingling sensation in this area, with occasional bursts of sharp, knife-like pain. After referral to a pain clinic, JD is prescribed oral gabapentin, which partially reduces his symptoms. However, he reports to the pain clinic again 2 months later, still in severe pain. At this time, amitriptyline is added to the gabapentin, and the pain is further relieved. Three years later, JD’s lingering pain has resolved and he no longer requires medication, but the lack of forearm sensation persists. Questions

1. What mechanisms produced and sustained the pain that lasted from JD’s exposure to the fire until his initial treatment?

2. What was the rationale for the sequence of medications used during the skin debridement operation?

3. Explain the mechanisms that could produce spontaneous pain in the region of the full-thickness burn months to years after healing of the skin and the rationale for using gabapentin to treat JD’s chronic pain.

4. Why was morphine tapered gradually and replaced with a combination oxycodone/acetaminophen tablet?

1. A client has been receiving intravenous paclitaxel for the past week for treatment of ovarian cancer. Identify an assessment finding that is a priority to report to the provider.
2. A nurse is working on the teaching plan for a client going home on raloxifene. What information should be addressed when teaching about raloxifene? Suggest pharmacology learning activity: chemotherapy agents

Briefly discuss the pharmacology of any two named artemisinin-based combination therapy. Classify Cephalosporins and thus discuss the mechanism of action, adverse effects and therapeutic uses of third generation of cephalosporins.

Liza is a 48-year-old mom of three who was receiving radiation and chemotherapy. She developed a fever and stomach cramps. Shortly after she had bouts of diarrhea and saw what looked like small amounts of blood in her stool.

– What kind of infection do you suspect for this patient and why do you have that hypothesis?

– What sample do you want to take from your patient and have grown on nutrient agar?

You will need to request at least stains and/or biochemical tests during the identification process Name of the staining process or biochemical test (Please give me the name of the test) What Exercise in your lab manual will you use to help you understand and interpret your results? Give a brief explanation of what this test is looking for and how you will interpret the results. Be sure to answer these prompts in your response:

– What biochemical function are you testing for? (For example you might be testing for the Gram reaction, or the presence or absence of a capsule, or the ability to ferment sucrose or the ability to digest starch, etc.)

– What will a positive reaction look like and what will a negative reaction look like? (Will there be a color difference or an absence of growth or something else? Will you be able to interpret the picture of the results when you get it?)
