answer: Best before date is the correct answer. Best before date must be marked on ready-to-eat bags (PHFs). Best Before date means that the product will be of the best quality or condition.
A five-year-old presents to the emergency department with epiglottitis
the nurse's first priority should be control of anxiety,facilitation of learning, Medications, and Hydration.
<h3>
Epiglottis</h3>
The throat's epiglottis, a leaf-shaped flap, serves to keep food and liquids out of the windpipe and the lungs. When breathing, it remains open, allowing air to enter the larynx. It closes during swallowing to stop food from being inhaled into the lungs, forcing any liquids or food to travel down the esophagus and toward the stomach.
<h3>Interventions in Nursing</h3>
For a child with epiglottitis, the nursing interventions are:
- control of anxiety:- The family should demonstrate personal activities that will help the youngster get rid of or lessen emotions of anxiety and stress that are coming from an unknown source.
- facilitation of learning:- In addition to encouraging progress in the patient's capacity and openness to accept information, the nurse should support their ability to process and comprehend information.
- Medications:- As directed, give antibiotics such as cefuroxime.
- Hydration:- Since the child couldn't swallow, adjust the IV fluid as necessary.

Answer:
Bacteria are highly adaptable microorganisms who have the capability of developing defense mechanisms against that which may harm them. Not least important of all, is the easiness with which some bacteria, especially pathogenic bacteria like Salmonella, or Klebsiella, develop mechanisms of resistance to antiseptics and, most importantly, antibiotics.
Antibiotics are a chemical substance that was created, and has been developed, in order to be able to combat pathogenic microorganisms, specifically bacteria. However, because today these substances are being used indiscriminately, we are now seeing a very worrying pattern of antibiotic-resistance patterns in microorganisms that used to be sensible to them. The result, we are facing strains of pathogenic bacteria, like Klebsiella pneumonia and E. Coli, that have become resistan to all types of antibiotics, from first generation, to fourth generation. And this has meant that when people acquire infection by these pathogens, the likelihood of death by them has increased because there are no agents capable of combating them.
Exposure to antibiotics has been the sole reason why these resistant strains of bacteria have emerged, especially when these antibiotics are not necessary. And feeding these substances to animals, to ensure their development and weight gain, has not made the situation any better. Now, we are instead adding also bacteria to the list that did not use to be resistant, but that are becoming so as they become adjusted to the constant exposure to antibiotics. Again, the result has been: more people infected with bacterial strains that cannot be combated with any of the existing antibiotic agents.
Answer:
14.8% of H2O2
Explanation:
Based on the redox reaction of H2O2/MnO4- is:
2MnO4- + 5H2O2 + 6H+ ⇄ 2Mn2+ + 5O2 + 8H2O
<em>2 moles of KMnO4 react with 5 moles of H2O2</em>
<em />
To solve this question we need to find the moles of KMnO4 until reach the endpoint. Using the balanced reaction, we can find the moles of H2O2 that must be converted to grams using its molar mass -Molar mass H2O2: 34.015g/mol-:
<em>Moles KMnO4:</em>
0.0297L * (1.4686eq/L) = 0.04362eq MnO4- * (1mol / 5eq) = 0.008723 moles MnO4-
<em>Moles H2O2:</em>
0.008723 moles MnO4- * (5mol H2O2 / 2mol MnO4-) = 0.02181 moles H2O2
<em>Mass H2O2:</em>
0.02181 moles H2O2 * (34.015g/mol) = 0.7418g H2O2
<em>%:</em>
0.7418g H2O2 / 5.0mL * 100
<h3>14.8% of H2O2</h3>
