$\begin{array}{|l|l|l|}
\hline\begin{array}{l}
\text { Number of months of } \
\text { experience }
\end{array} & \begin{array}{l}

\text { Medication Errors }
\end{array} \
\hline 1-3 & 6 & 6 \
\hline 4-6 & 17 & 23 \
\hline 7-9 & 12 & 35 \
\hline 10-12 & 10 & 45 \
\hline
\end{array}$ During what time frame were the most medication errors made?

Accepted Answer

The highest number of medication errors, 17, occurred during the 4-6 month period.

Question 2

A nurse orientation program director is examining data about nurses in their first year of practice at her hospital. Use the table below to answer the following question.
$\begin{array}{|l|l|l|}
\hline \begin{array}{l}
\text { Number of months of } \
\text { experience }
\end{array} & \begin{array}{l}
\text { Number of medication errors } \
\text { made }
\end{array} & \begin{array}{l}
\text { Cumulative Frequency of } \
\text { Medication Errors }
\end{array} \
\hline 1-3 & 6 & 6 \
\hline 4-6 & 17 & 23 \
\hline 7-9 & 12 & 35 \
\hline 10-12 & 10 & 45 \
\hline
\end{array}$ What percentage of the medication errors were made in the first nine months of practice?

Accepted Answer

The cumulative frequency of medication errors in the first nine months of practice is 35. The total number of medication errors is 45. Therefore, the percentage of medication errors made in the first nine months of practice is 35/45 * 100 = 77.8%.

Question 3

A nurse orientation program director is examining data about nurses in their first year of practice at her hospital. She notices that the number of medication errors increases after the three month supervised orientation ends and then slowly drops down again. The time period immediately after orientation is considered a critical juncture. What might she suggest to address this concern?
$\begin{array}{|l|l|l|}
\hline \begin{array}{l}
\text { Number of months of } \
\text { experience }
\end{array} & \begin{array}{l}
\text { Number of medication errors } \
\text { made }
\end{array} & \begin{array}{l}
\text { Cumulative Frequency of } \
\text { Medication Errors }
\end{array} \
\hline 1-3 & 6 & 6 \
\hline 4-6 & 17 & 23 \
\hline 7-9 & 12 & 35 \
\hline 10-12 & 5 & 40 \
\hline
\end{array}$

Accepted Answer

Requiring double signed medication administration documentation through the first six months of practice can provide an additional layer of oversight and support during the critical period immediately after orientation, potentially reducing medication errors.

Question 5

Researchers examined the relationship between interpersonal violence and health in college age women. They received 490 responses. Of those responses 89 women reported being abused at some point in their lifetime and 355 reported no history of abuse. What percentage of the sample were abused?

Accepted Answer

To find the percentage of women who reported being abused, divide the number of abused women (89) by the total number of responses (490) and multiply by 100. (89/490) * 100 = 18.2%.

Question 6

Researchers examined the relationship between interpersonal violence and health in college age women. Of those responses 92 women reported being abused at some point in their lifetime and 355 reported no history of abuse. 174 of the non-abused women and 58 of the abused women had a score of three or greater on the psychological distress scale. What was the cumulative frequency of scores less than three in non-abused women?

Accepted Answer

The cumulative frequency of scores less than three in non-abused women is the total number of non-abused women minus those who scored three or greater. So, 355 (total non-abused) - 174 (scored three or greater) = 181.

Question 7

Accepted Answer

If 76% of the allergic reactions were eliminated, then 24% of the original 317 reactions remained. 24% of 317 is approximately 76.

\end{array}$ Which state has the largest number of people who are do not have asthma and live with fair to poor health?

Accepted Answer

The table provides percentages, not the actual number of people, so we cannot determine which state has the largest number of people without asthma living in fair to poor health without additional population data.
