A nurse reconstituted a vial of 750 mg Cefuroxime Sodium Powder for Injection with 6mL of sterile water for injection. The reconstituted solution was dark amber-colored solution. The package insert states that solution colors range from clear to yellow depending on concentration, diluent, and storage conditions. The nurse was then hesitant to give the patient the solution due to its unusual dark color. Five portions were taken from a batch of cefuroxime sodium. Prior to testing in the instrument, each part was subjected to one of the following conditions: Conditions Specifications Temperature Portion 1: 8°C ± 2°C Portion 2: 30°C ± 2°C Portion 3: 40°C ± 2°C Light Portion 4: Kept in the dark Portion 5: Exposed to direct sunlight 1. Which form of the product – the powder for injection, the reconstituted product, or both – will you subject to the following conditions? Why do you think these forms can best address the problem?

A stool specimen from a 20-year-old man was sent to the Oregon State Public Health Laboratory for examination. An FEA (formalin-ethyl acetate) concentration was performed and wet mounts prepared for examination. The objects seen in the images were present in moderate numbers and ranged in size from 33 to 40 micrometers (Figures A and B). The specimen also contained several large objects that were forwarded to CDC for identification. The objects averaged 1 centimeter in length. The images show one of the submitted objects after clearing with lactophenol solution, before (Figure C) and after injecting with ink. What is your diagnosis? Based on what criteria? How does the patient acquire this infection? What is the infective stage? Introduce the pathogenesis of this infection briefly.
