Q

How is analyte concentration expressed in a percent solution?

A

The amount of solute per 100 total units of solution are expressed as:

  • w/w = grams of solute per 100 g
  • v/v = mililiters of solute per 100 ml
  • w/v = grams / dL of solution
21
Q

What is molarity?

A

Molarity describes the number of moles per 1 liter of solution.

22
Q

What is molality?

A

Molality describes the amount of solute per 1 kg of solvent (w/w).

23
Q

What is normality?

A

Normality describes the number of gram equivalent weight per 1 liter of solution.

24
Q

What solution is recommended by the CDC for disinfection of laboratory surfaces?

A

1:10 sodium hypochlorite (bleach) solution

25
Q

List 5 categories of fire, stating examples of combustible material for each category:

A

See table below:

26
Q

What is quality management?

A

Quality management is a system - wide process of ensuring quality patient care.

27
Q

List at least 3 instances in which you should wear gloves:

A
  1. Handling blood, body fluids, secretions, excretions and contaiminated items
  2. Touching mucous membranes and non-intact skin
  3. Before patient contact
  4. After gloves are removed
  5. Before entering designated break areas
  6. Before and after bathroom use
28
Q

Define range.

How is it calculated?

A

Range represents extremes in a data set.

See below:

29
Q

Define accuracy:

A

Accuracy calculates the closeness of a measurement to a specific value.

30
Q

Define precision:

A

Precision is the variation of measurement related to each other.

31
Q

Define mean.

How is it calculated?

A

The mean represents the average of a set of data points:

∑ = sum of all numbers in the data set

X = represents each data point within a set

N = the total amount of numbers included in the data set

See formula below:

32
Q

Define median.

How is it calculated?

A

Median is the middle point in a set of data points arranged from lowest to highest.

See formula below:

33
Q

Define mode.

How is it calculated?

A

Mode is the most frequently occurring value in the data set.

See below:

34
Q

Define coefficient of variation (CV).

How is it calculated?

A

CV is the ratio of the standard deviation to the mean which compares the amount of variation from one data series to another

See below:

35
Q

What is a random error?

Define systematic error:

A

Random Error

The unexpected difference between the test and reference method results.

Systematic Error

Differences in data sets run consistently in one direction (either higher or lower).

36
Q

Define specificity.

How is it calculated?

A

Specificity describes the percent chance that the test will correctly identify a person that has the trait/disease.

Sensitivity = TP / TP + FN

  • TP = true positive
  • FN = false negative
37
Q

What is the formula for calculating Negative Predictive Value (NPV)?

What does NPV measure?

A

NPV = TN / TN + FN

  • TN = true negative
  • FN = false negative

NPV measures the percent chance that a patient with a (-) result is disease free.

38
Q

What is the formula for calculating Positive Predictive Value (PPV)?

What does PPV measure?

A

PPV = TP / TP + FP

  • TP = true positive
  • FP = false positive

Percent chance that a patient with a (+) result actually has the disease.

39
Q

Refer to the illustration below.

What is this diagram called?

A

Levy - Jennings chart

47
Q

Refer to the illustration below:

Identify the Westgard rule that is violated in the diagram:

A

48
Q

Define osmotic pressure:

A

Osmotic Pressure is exerted when a solvent flows through a semipermeable membrane to establish equilibrium concentration of different concentration.

The result is expressed as osmoles.
