Answer:
231 ml
Explanation:
Let x represent the amo unt of Dextrose 70% in ml and y represent the amount of Dextrose 5% in ml needed to prepare 1,000mL of Dextrose 20%.
Since 1000 ml of Dextrose 20% is needed, hence:
x + y = 1000 (1)
Also 70% Dextrose is mixed with 5% dextrose to produce 20% dextrose. i.e.:
70% of x + 5% of y = 20% of 1000
0.7x + 0.05y = 200 (2)
We have to solve equations 1 and 2 simultaneously.
Let us multiply equation 2 by 20:
14x + y = 4000 (3)
subtract equation 1 from 3:
13x = 3000
x = 231 ml
Put x = 231 in equation 1 to find y:
231 + y = 1000
y = 769 ml
Therefore 231 ml of Dextrose 70% must be mixed with 769 ml of Dextrose 5% to prepare 1,000mL of Dextrose 20%? *
Adults with presbycusis may have difficulty in discriminating fricatives because they have fewer functional nerve cells in the inner ear, which makes the inner ear work harder to process and transmit sound when background noise is present.
This indicates that the inner ear and brain are not effectively communicating with one another.
Presbycusis is the gradual hearing loss that most people experience as they age.
An age-related disorder that is common is hearing loss.
A hearing loss affects 30-35 percent of persons over 65. A hearing loss affects 40–50% of adults aged 75 and older, according to estimates.
Its primary symptom is trouble discriminating fricatives from background noise as the inner ear has to work harder to process and transmit sound when background noise is present because they have less functioning nerve cells.

If you enter a medication order in your hospital's ehr and a warning screen pops up saying that your patient's medication dose should be adjusted based upon her last lab results. What this block best exemplify is: How technology that tend to dictates a work instead of facilitating it can introduce unplanned problems.
<h3>What is medication?</h3>
Medication can be defined as the process of using drugs to treat a sick person.
Based on the given scenario assuming the patient has a lab draw more recently-recorded at a clinic that is not your own clinic which inturn shows values that is different from yours and therefore not available in your EHR which full meaning is Electronic Health Record. What the block exemplify is how technology that tend to dictates a work instead of facilitating it can introduce unplanned problems or unintended issues.
Therefore technology that dictates a work instead of facilitating it can introduce unplanned problems.
The complete question is:
You enter a medication order in your hospital's EHR, and a warning screen pops up saying that your patients medication dose should be adjusted based upon her last lab results. However, you know that the patient has a lab draw more recently- recorded at a different clinic and therefore not available in your EHR- that showed different values. When you attempt to move past the warning, the system will not allow you to proceed. What does this block best exemplify?
