The incorporation of valinomycin, a neutral antibiotic, into a polyvinyl chloride membrane allows for the manufacture of an ion-selective electrode that is highly selective for potassium.

<h3>How Valinomycin Ionophores Enter and Transport K+ across Model Lipid Bilayer Membranes?</h3>

  • A biomimetic lipid membrane attached to the surface of the gold electrode contained the cyclic peptide valinomycin.
  • The ionophore characteristics of the peptide were investigated using electrochemical impedance spectroscopy, and the conformation and orientation of the antibiotic valinomycin within the membrane were identified using polarization modulation infrared reflection absorption spectroscopy.
  • By forming a complex with potassium ions and an ion pair with a counter anion, valinomycin transports ions across the membrane, and the combination of these two techniques revealed novel information about the ionophore mechanism.
  • The ion pair is located inside the hydrophobic portion of the membrane and makes a little angle of around 22° with the surface normal.

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.

Further Explanation:

Scientific investigations usually begin with observations. These are typically something that would catch the researcher’s attention. Then, the scientist comes up with a hypothesis which is a testable explanation for the phenomenon or what’s occurring a prediction is usually made based on the hypothesis.

A prediction of the outcome is usually made based on the hypothesis, after which it is tested via an experiment. The scientist then use the results to make new hypotheses or predict certain outcomes.
