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.
View Photographer's Profile. Hoover Dam on the Colorado River forms the largest reservoir in United States in maximum water capacity, Lake Mead. Previously much of the traffic from Arizona to Las Vegas, Nevada crossed the river on the road across the dam. But since the construction of the Mike OâCallaghan â Pat Tillman Memorial Bridge (Colorado River Bridge), traffic over the dam has been limited. The bridge is 900 feet over the river.
