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:
epiglottis
Explanation:
I think it may be the epiglottis. The epiglottis is the flap of flesh that closes whenever you are not eating, so you won't be able to inhale something.
Answer:
So that the baby is no longer attached to the placenta.
Answer:
The water flowing in rivers still originates from precipitation, but it is not all from surface runoff. This groundwater seepage is vitally important to the hydrologic settings of the world because it is responsible for keeping water in rivers during times of no rainfall. Also, the evaporative phase of the cycle purifies water which then replenishes the land with freshwater. The flow of liquid water and ice transports minerals across the globe. It is also involved in reshaping the geological features of the Earth, through processes including erosion and sedimentation.

The technique made by the nurse is keeping sterile field above waist level.
<h3>Which technique is made by the nurse to insert an indwelling urinary catheter?</h3>
Similar to an intermittent catheter, an indwelling urinary catheter is implanted, but it is left in place. A water-filled balloon keeps the catheter in the bladder and prevents it from escaping. These catheters are frequently referred to as Foley catheters.
The sole approved usage for indwelling urinary catheters is short-term, or fewer than 30 days (EAUN recommends no longer than 14 days.) Urine incontinence (UI) and urinary retention are two frequent bladder dysfunctions for which the catheter is implanted for continuous bladder drainage.
In order to produce a sterile field, sterile surgical drapes must be placed around the patient's surgical site and on the stand that will contain the sterile instruments and other supplies required for the procedure. The maintenance of a sterile environment is crucial to the prevention of infection. These collection of procedures that are followed before, during, and after invasive procedures help to lower the risk of post-procedure infection by reducing the number of potentially contagious microbes.
Hence, The technique made by the nurse is keeping sterile field above waist level.
