From the calculations and the information taht we can glean from the question, the mass of the antibiotic left after 12 hours is 8.59 mg.
<h3>What is decay?</h3>
The term decay has to do with the breakdown of a chemical substance. Since the decay depends only on the initial amount of the drug the process folows the first order kinetics.
Hence;
N = amount left at time t
No= amount initual present
t = time taken
t1/2 = half life of the drug
N/No = (1/2)^t/t1/2
N/550 = (1/2)^12/2
N = 550[(1/2)^12/2]
N = 8.59 mg

Answer:
The answer is B double-blind study
Explanation:
In this type of scientific study neither the experimenter nor the researcher knows the study sample, during the period that the experiment lasts, in order not to influence the results.
Yes, it is appropriate for the nurse to recommend smoking cessation for clients with hypertension because nicotine in cigarettes causes your blood vessels to constrict and the heart to beat more rapidly, thus raising your blood pressure.
Nicotine is a extremely addictive chemical compound present in a tobacco plant. Nicotine is a stimulant, which makes tobacco products addicting. Even when people wish to stop using tobacco products, nicotine prevents them from doing so.
Because of ongoing tobacco use, the number of deaths and disabilities attributable to tobacco use is rising globally (mainly cigarettes). While tobacco use is steadily increasing in high-income countries like the USA, it has reached epidemic proportions in many low- and middle-income nations (The Tobacco Atlas 2015; CDC 2016). 68 % of adult smokers in the United States want to stop, and millions have tried to do so, according to the Centers for Disease Control (CDC 2017).
Each year, 70 % of smokers contact a healthcare provider (AHRQ 2008). Since nurses participate in the majority of these visits and constitute the biggest group of healthcare providers globally, they have the potential to have a significant impact on the decline in tobacco use.
