Answer: Δβ = 28.5278 dB
Explanation:
from the question we are given that;
the sound gathering area Ga = 15.0 cm²
total area Ae = 0.800 cm²
efficiency ε = 38 %
therefore we have that the effective gathering area of the stethoscope is;
As = ε Ga
As = 38 % × 15 = 5.7 cm²
But I ∝ 1/A
where Ie/Is = As/Ae
Ie/Is = 5.7/0.800 = 7.125
given that we are to assume that sound is transmitted into a stethoscope 100 times, this gives
I'e/I's = Ie/Is × 100 = 7.125 × 100 = 712.5
Δβ = βe - βs = (10dB) log (I'e/Io) - (10dB) log (I's/Io)
Δβ = (10dB) log (I'e/I's)
Δβ = (10dB) log (712.5) = 28.5278
Δβ = 28.5278 dB

Answer:
director of nursing
Explanation:
Nurses are the healthcare professionals who spend the most time with patients and their families during their hospital stay. Doctors may cure, but nurses are responsible for providing care. Besides providing medical attention, they also provide important emotional support.
The nurse will perform pulse oximetry to monitor the effectiveness of the oxygen therapy ordered for the client.
<h3>What is pulse oximetry?</h3>
The oxygen saturation level of your blood can be measured with a non-invasive procedure called pulse oximetry.
It can quickly identify even minute variations in oxygen levels. These levels demonstrate how well blood transports oxygen to your arms and legs, which are the extremities that are farthest from your heart. It looks like a little clip and is called a pulse oximeter. It fastens to a body component, usually a finger.
Pulse oximetry is helpful for postoperative patients, monitoring individuals at risk for hypoxia, titrating oxygen therapy, and monitoring patients receiving oxygen therapy.
