For radioactive decay:
N = N(0) x exp(-λt), where λ is the decay constant equivalent to ln(2)/half life, N is the amount after a given amount of time, t is the time passed and N(0) is the initial amount.
1)
N = 24 x exp(-ln(2)/4.5 x 36)
N = 0.09375 mg
2)
1.2 = 9.6 x exp(-ln(2)/4.5 x t)
ln(1.2/9.6) = -t x ln(2)/4.5
t = 13.5 days
Answer:
Remain with the client and be silent
Explanation:
Bowel obstruction can be explained or described as a situation whereby the intestines, i.e, both small and large intestines are blocked, and thereby, preventing the normal movement of food, liquid or stool in the intestines.
The blockage could result or occur due to tumor, foreign substance or digestive problem.
The Miller-Abbott tube is the tube that was invented or developed to treat the obstruction that is present in both the small and the large intestines. It is used by passing it through the stomach into the intestine.
In this case, the bowel obstruction is caused by recurrent malignancy, that is recurrent of formation of tumor.
The best thing the nurse should do, is to remain silent and with the client, until the client is ready for explanation on the process, and that he/she is in position and capable of inserting the tube.
True! Entomologist study insects!
