the recommended dose for gentamicin is 5mg/kg/ day in threee divided doses.If a patient weighs 164lb, how many milligrams should that patient receive for each dose?
which of the following drugs is classed as an h2 antagonist?
convert 164 lb to kg;
5 mg/kg/day * 1day/3doses
= 5/3 mg/kg per dose
Multiply this number by the weight of the patient in kg
To calculate the recommended dose of gentamicin for a patient weighing 164 lb, you need to convert their weight from pounds to kilograms and then multiply it by the recommended dose per kilogram.
Step 1: Convert the patient's weight from pounds to kilograms.
1 lb is approximately equal to 0.4536 kg. Therefore, you can convert 164 lb to kg by multiplying it by 0.4536:
164 lb * 0.4536 kg/lb = 74.38944 kg (approximately)
Step 2: Calculate the recommended dose per day.
The recommended dose of gentamicin is 5 mg/kg per day. Multiply the patient's weight in kilograms by the recommended dose per kilogram:
74.38944 kg * 5 mg/kg = 371.9472 mg/day
Step 3: Determine the dose per each divided dose.
The recommended dose is divided into three doses per day. Divide the total dose per day by three to get the dose per each divided dose:
371.9472 mg/day / 3 doses = 123.9824 mg
Therefore, each divided dose for a patient weighing 164 lb should be approximately 124 mg.
As for the second question, an H2 antagonist is a class of drugs that reduce the production of stomach acid. The following drugs are classed as H2 antagonists:
1. Cimetidine
2. Ranitidine
3. Famotidine
4. Nizatidine
These drugs are commonly used to treat conditions such as gastric ulcers, gastroesophageal reflux disease (GERD), and Zollinger-Ellison syndrome.
