Question 1

If the hospital policy states that each nurse on the ICU floor should attend to two patients (so that the quality of care is not compromised) and there are currently 16 patients on the floor, how many nurses are needed?

Accepted Answer

16 patients/2 nurses = 8 nurses needed.

Question 2

A specific type of drug should be stored at 10° C. What temperature should the refrigerator be set to in degree Fahrenheit?

Accepted Answer

[(10° C * 9/5) + 32] = 50° F.

Question 3

The group practice's policy is that for every seven physicians in the group, there should be two medical assistants (MAs). If there are 15 physicians in the group, how many MAs should the practice employ?

Accepted Answer

2 MAs/7 physicians = 0.2857 MAs per physician; 0.2857 MAs * 15 physicians = 4.2857; because you can't have a piece of a person, you must round up to the nearest person = 5 MAs. It is also possible to employ four full-time MAs and one part-time, with the resultant total being five in either case.

Question 4

In the decimal 0.042359463, the digit 2 is in the __________ place.

Accepted Answer

The digit 2 is in the thousandth place.

Question 5

A newborn baby weighs 8 pounds 6 ounces. How much does the baby weigh in grams? [1 lb = 0.45 kg and 1 oz = 28 g]

Accepted Answer

First, we need to convert pounds to kilograms: 
8 lb x 0.45 kg/lb = 3.6 kg

Then, we need to convert ounces to grams: 
6 oz x 28 g/oz = 168 g

Finally, we add the weight in kilograms to the weight in grams: 
3.6 kg + 168 g = 3,768 g

Therefore, the baby weighs 3,768 grams. The best choice is C.

Question 6

A physical therapy center on the east side of town sees 24 patients a day. A larger, competing center on the west side of town sees 46 patients a day. What is the simplest ratio of east side patients to west side patients?

Accepted Answer

24:46 = reduces to 12:23.

Question 7

Round this decimal to the hundredth place: 0.14289.

Accepted Answer

0.14289 rounded to the hundredth place is 0.14.

Question 8

An epidemiological report stated that 0.00684 births in the United States were carried out via cesarean section last year. How many births was this?

Accepted Answer

6.84 of every 1,000 because the "6" is in the thousandth decimal place.

Question 9

Drug dosage instructions state that 7.5 mL of the drug should be mixed with 37.5 mL of saline solution and be administered intravenously over the course of 2 hours. How many tablespoons of saline solution are needed? [1 Tbsp = 15 mL]

Accepted Answer

37.5 mL/15 mL = 2.5 Tbsp.

Question 10

Sally can code six charts in 1 hour. What is the ratio of minutes to charts?

Accepted Answer

1 hour = 60 minutes; 60 minutes/6 charts = 10 minutes:1 chart.

Question 11

While looking at salaries of physicians at the hospital, you find a range from a low of $125,000 to a high of $380,000. How many classes would you have if you broke them into class widths of $15,000?

Accepted Answer

$380,000 - $125,000 = $255,000/$15,000 = 17 classes.

Question 12

How many grams are in 1 kg?

Accepted Answer

There are 1,000 grams in 1 kilogram.

Question 13

In a primary care physician's office, 68 out of 112 patients consented to receive the flu vaccine. What percentage of patients received the vaccine? Rounded to the nearest decimal.

Accepted Answer

60.7% = 0.60714286 = 68/112 = observations/total observations.

Question 14

Amy can usually answer one e-mail in 3 minutes. If her inbox has 16 messages, how long will it take her to respond to all messages?

Accepted Answer

Amy takes 3 minutes to answer one email. For 16 emails, it will take her 3 * 16 = 48 minutes.

Question 15

Two people, Mark and Tim, are both coding medical records. Mark codes eight records every 35 minutes (8:35). Tim, on the other hand, codes 15 records an hour (15:60). Who is faster and by how much?

Accepted Answer

Mark = (35 minutes/8 records = 1 record every 4.375 minutes), Tim = (60 minutes/15 records = 1 record every 4 minutes); Tim is faster by (4.375 minutes - 4 minutes = 0.375 minutes).

Question 16

What is the standard deviation of outpatient surgeries?

Accepted Answer

The answer of What is the standard deviation of outpatient...

Question 17

One of the clinics attached to the hospital system handles walk-ins and provides some urgent care services. Of the 110 patients seen last month, 40 had broken bones, 35 had flu-like symptoms, 25 were dehydrated, 4 received MRI scans, and 6 were sent to the hospital for immediate surgery. Report these conditions in simple fractions.

Accepted Answer

To convert the fractions to their simplest form, we need to divide the numerator and denominator by their greatest common factor. The number of patients seen last month (110) is the denominator for all fractions. The fractions in choice C are in their simplest form and match the given data.

Question 18

A normal distribution uses standard deviation to show how scores are expected to cluster around the calculated average of a sample or population. What type of shape do these graphs tend to make?

Accepted Answer

A bell curve.

Question 19

The larger the standard deviation, the data tends to _______________________.

Accepted Answer

The larger the standard deviation, the data tends to be more varied from the mean.

Question 20

Midville Lutheran Hospital treated a total of 64 patients at its Saturday morning clinic. 22 of the patients were female, while 14 were male. What was the ratio of females to males (in the most reduced form)?

Accepted Answer

22 females:14 males = 11 females:7 males.
