Step 1. Calculate the 24 hr morphine dose: 3 mg x 24 = 72 mg IV morphine/24 hrs; Step 2. Convert IV to oral morphine: at a ratio of 1 mg IV = 3 mg oral; thus 72 mg IV = 216 mg po/24 hours; Step 3. Convert the oral morphine dose to Duragesic - there are two methods: METHOD 1. Look in the PDR, find the morphine conversion table, it says that 135-224 mg of morphine = 50 mcg patch. Note, this range of morphine is very broad; 50% of patients will be under-dosed when this conversion table is used. METHOD 2. Use a ratio of MS:fentanyl of 100:1; 216mg/100/24hrs = 90 mcg/hr, can rounded to 75 mcg or 100 mcg patch.
The bridge is an engineering feat on its own and there is an informative foot path up to the bridge and a pedestrian walkway across it. You can get great photos of the bridge from Hoover Dam and of Hoover Dam from the bridge. Standing over that much air was a little unnerving for me, but still pretty neat.
Hoover Dam Tours. The Hoover Dam is a worldâfamous concrete archâgravity dam that is located 30 miles southeast of Las Vegas on the border between Nevada and Arizona. It impounds the mighty Colorado River in the Black Canyon. The dam was designated a National Historic Landmark by congress in 1985.
