You have just started working in an Urgent Care Clinic as a nurse.  Mom brings in her 3 year old little boy, Brandon.  Mom states that Brandon has been having fever up to 104F and he isn't eating or drinking anything because he feels very sick to his stomach, not to mention crabby!  He's also been pulling a lot at his right ear and sounds congested.  At the last well visit with the Pediatrician (about 2 weeks ago), Mom states that Brandon weighed 32 pounds. On exam today, his weight is 12.5 kg.  Additionally his eyes are darkened and sunken, his mouth is dry with some white crusting around the lips.  His temperature is 39C, other vitals signs are normal.  Though he looks ill he appears to be medically stable.  The doctor rushes in, quickly exams Brandon, diagnoses him with otitis media and then barks off orders to you that you then need to convey accurately to Mom.  The orders include:  push fluids, ibuprofen 10mg/kg every 6 hours if temp > 38C, and begin taking a 10-day course of…

Carbohydrate Requirements (sugars and starch in rice, potato, pasta, bread, sugar, fruits, ete.) : The Institute of Medicine recommends adults consume on average 50 percent of their daily calories from carbohydrates. Since carbohydrates contain about 3.94 calories in each gram and recommended daily calories intake for an average person is 2,100 cal, calculate how many grams of carbohydrate average person need to eat per day? (Hint: first find how many calories should be coming from the carbs, then convert them to grams). Use two sig figs for this answer and the other two below, and enter number only, no units. Protein Requirements (high-protein foods include lean meats, poultry, seafood, soyysroducts, eggs, dairy foods, nuts and seeds): Adults should consume about 20 percent of their energy intake from protein. Since protein provides 5.65 calories per gram, if a person eats a 2,100-calorie diet, how many grams of protein does he/she need to consume daily? Fat Requirements (eat healthy…

Please answer the following question:

During the combustion of 5.00 g of ethanol (C2H5OH) 35.5 kcal of energy are released. How many grams of ethanol must be burned to release 450. kcal of energy? Report your answer to 3 sig figs. Do not include units and do not put your answer in scientific notation.(hint: there are several ways to correctly do this problem. Dimensional analysis is one of them. But in this case there's an easier way, if you can think of it. Remember, enthalpy is extensive. That's the point of this question.)

The maximum dose over 24 hours for OTC (over the counter use) of acetaminophen (medication in Tyleonol) is 4,000 mg.  Many OTC and prescription medications contain acetaminophen along with other ingredients.  Acetaminophen can be found in many cold medicines and in prescription painkillers such as Norco, which also contains the addictive opiod hydrocodone.  Keeping track of sources and amount of acetaminophen is very important for your health.  Abuse of Norco due to the opiod can also lead to toxic/lethal doses of acetaminophen. There are now strict regulations on the number of tablets of Norco that can be prescribed (7 day maximum per prescription, not refillable without another prescription).     A tablet of Norco contains 325 mg of acetaminophen.  Thirty tablets are in a week-long prescription post major-surgery to aid in recovery.  How many grams of acetaminophen are in the 30 tablets?

In an effort to moderate the interior temperature of their home during a heat wave in July, Shakir turns on the air conditioner.

Public water systems often add fluoride to drinking water because, in the proper amounts, fluoride improves dental health and prevents cavities. Too much fluoride, however, can cause fluorosis, which stains teeth. In 2015, the U.S. Public Health Service (PHS) revised its 1962 recommenda- tions for the amount of fluoride in public water systems. The 1962 recommendations depended on the average temperature for the region in question as shown here. because U.S. citizens are now getting fluoride from other sources, including toothpaste and mouthwash. The rec- ommended level balances the need for fluoride to im- prove dental health with the risk of developing fluorosis from too much fluoride. Examine the data in the table and answer the following questions: (a) Determine the percent change in optimum recom- mended fluoride concentration for a water system with annual average maximum daily temperatures of 17.8–21.4 °C. Hint: the percent change is given by 1962 Fluoride Recommendations final…

One of the best-selling light, or low-calorie, beers is 4.2% alcohol by volume and a 12-oz serving contains 110 Calories; remember: 1 Calorie = 1000 cal = 1 kcal. To estimate the percentage of Calories that comes from the alcohol, consider the following questions. Write a balanced chemical equation for the reaction of ethanol, C2H5OH, with oxygen to make carbon dioxide and water.
