Question 1: A survey firm must make phone calls to 136 people. To make the 136 long-distance calls, how many buttons must be pressed?

• 1360 (Correct answer)
• 800
• 1600
• 1300

Correct answer: 1360

This question assumes a standard number of buttons pressed for each long-distance phone call. If each call requires 10 button presses (e.g., '1' + area code + 7-digit number), then for 136 calls, the total number of button presses would be 136 calls * 10 buttons/call, which equals 1360 buttons.

Question 2: 1 liter contains how many milliliters?

• 300
• 1000 (Correct answer)
• 2000
• 10

Correct answer: 1000

The metric system is based on powers of 10 for unit conversions. A milliliter (mL) is defined as one-thousandth of a liter (L). Therefore, there are exactly 1000 milliliters in 1 liter.

Question 3: Each pound has 453.59 grams. 6,577 grams is the weight of a baby. In pounds and ounces, how much does the baby weigh?

• 17 lb 8 oz.
• 14 lb 8 oz. (Correct answer)
• 12 lb 5 oz.
• 35 lb 8 oz

Correct answer: 14 lb 8 oz.

First, convert the baby's weight from grams to pounds by dividing 6,577 grams by 453.59 grams/pound, which yields approximately 14.5 pounds. Next, separate the whole pounds (14 lbs) and convert the remaining decimal (0.5 lbs) into ounces by multiplying by 16 ounces/pound (0.5 * 16 = 8 ounces). Thus, the baby weighs 14 pounds and 8 ounces.

Question 4: The waist circumference of a man is 88.9 centimeters. What is his waist measurement in inches?

• 45 in.
• 35 in. (Correct answer)
• 25 in.
• 25.5 in.

Correct answer: 35 in.

To convert a measurement from centimeters to inches, you divide the centimeter value by the conversion factor of 2.54 centimeters per inch. Therefore, 88.9 cm divided by 2.54 cm/inch equals exactly 35 inches.

Question 5: In Celsius, what are 98.6 degrees Fahrenheit?

• 37 degrees Celsius (Correct answer)
• 119 degrees Celsius
• 86.70 degrees Celsius
• 70.50 degrees Celsius

Correct answer: 37 degrees Celsius

To convert degrees Fahrenheit to Celsius, use the formula C = (F - 32) * 5/9. Substituting 98.6 degrees Fahrenheit, the calculation is (98.6 - 32) * 5/9 = 66.6 * 5/9 = 37 degrees Celsius. This is the standard normal human body temperature.

Question 6: A meter is made up of how many centimeters?

• 100 (Correct answer)
• 10000
• 1000
• 1\/1000

Correct answer: 100

In the metric system, the prefix 'centi-' denotes one-hundredth. Therefore, a centimeter is one-hundredth of a meter, meaning there are 100 centimeters in 1 meter.

Question 7: In its simplest form, express 0.125 as a fraction.

• 1\/8 (Correct answer)
• 1\/30
• 1\/10
• 1\/15

Correct answer: 1\/8

To express the decimal 0.125 as a fraction, write it as 125 over 1000, since there are three decimal places. Then, simplify the fraction 125/1000 by dividing both the numerator and denominator by their greatest common divisor, which is 125, resulting in the simplest form 1/8.

Question 8: In its simplest form, express 35 percent as a fraction.

• 7\/20 (Correct answer)
• 5\/10
• 1\/2
• 5\/10

Correct answer: 7\/20

To convert a percentage to a fraction, divide the percentage value by 100. So, 35% becomes 35/100. Then, simplify this fraction by dividing both the numerator and the denominator by their greatest common divisor, which is 5, yielding the simplified fraction 7/20.

Question 9: How do you represent 7\/40 as a percentage?

• 17.5% (Correct answer)
• 20%
• 17%
• 22%

Correct answer: 17.5%

To convert a fraction to a percentage, divide the numerator by the denominator and then multiply the result by 100. For the fraction 7/40, dividing 7 by 40 gives 0.175. Multiplying 0.175 by 100 results in 17.5%.

Question 10: Covert the following military hours to civilian hours: 20:30

• 2:30 PM
• 9:30 AM
• 8:30 PM (Correct answer)
• 10:30 AM

Correct answer: 8:30 PM

To convert military time (24-hour format) to civilian time (12-hour format), if the hour is 13 or greater, subtract 12 from the hour and append 'PM'. For 20:30, subtracting 12 from 20 gives 8, so the civilian time is 8:30 PM.

Question 11: How many centimeters is 1 foot? (Note that one inch equals 2.54 cm.)

• 30.48 centimeters (Correct answer)
• 27 centimeters
• 35 centimeters
• 15 centimeters

Correct answer: 30.48 centimeters

First, convert 1 foot to inches, knowing that 1 foot equals 12 inches. Then, convert these 12 inches to centimeters by multiplying by the given conversion factor of 2.54 cm per inch. So, 12 inches * 2.54 cm/inch = 30.48 centimeters.

Question 12: In a military hospital, a nurse's shift runs from 1400 to 2100. When does the nurse start and finish her shift?

• 10 am to 3 pm
• 3am to 8 pm
• 2 pm to 9 pm (Correct answer)
• 3 pm to 10 pm

Correct answer: 2 pm to 9 pm

To convert military time to civilian time, subtract 12 from any hour greater than 12 and designate it as PM. Therefore, 1400 becomes 2 PM (14 - 12 = 2), and 2100 becomes 9 PM (21 - 12 = 9), meaning the nurse's shift is from 2 PM to 9 PM.

Question 13: In grams, how would 350 milligrams be expressed?

• 0.350 (Correct answer)
• 0.35
• 3.50
• 0.035

Correct answer: 0.350

To convert milligrams to grams, you divide the number of milligrams by 1000, as there are 1000 milligrams in 1 gram. Therefore, 350 milligrams divided by 1000 equals 0.350 grams.

Question 14: Every 8 hours, the patient must take pain medication. When will they receive the third dose, if the first dose was \r\ngiven at 22:00 (military time)?

• 2:00 PM
• 6:00 AM
• 10:00 PM
• 8:00 AM

The first dose is at 22:00. The second dose is 8 hours later, at 22:00 + 8 hours = 30:00, which is 06:00 the following day. The third dose is another 8 hours after that, at 06:00 + 8 hours = 14:00. Converting 14:00 military time to civilian time, we subtract 12, resulting in 2:00 PM.

Question 15: The active component in a pill is 0.45 mg. What fraction would this decimal be expressed as? Make sure you write it\r\n in the simplest form.

• 9\/20 (Correct answer)
• 4\/7
• 7\/10
• 8\/15

Correct answer: 9\/20

To convert the decimal 0.45 to a fraction, write it as 45 over 100, since there are two decimal places. Then, simplify the fraction 45/100 by dividing both the numerator and denominator by their greatest common divisor, which is 5, resulting in the simplest form 9/20.

Question 16: For the day, a patient on a clear diet consumes the following: <br>\r\n2 quarts water <br>\r\n1 clear soup serving (8 oz.) <br>\r\n1 cup of coffee (8 oz.) <br>\r\nHis drainage bag shows 1,000 mL for the previous day, according to a nurse who is checking his intake and output. <br>\r\nWhat is his milliliter deficit?

• 440 mL (Correct answer)
• 500 mL
• 350 mL
• 550 mL

Correct answer: 440 mL

To calculate the milliliter deficit, first convert all intake to milliliters. Using standard medical conversions (1 oz = 30 mL and 1 pint = 16 oz), we can infer that '2 quarts' in the problem likely intended to be '2 pints' for the given answer to be correct. If we assume '2 pints' of water (32 oz), the intake is: 960 mL (2 pints x 16 oz/pint x 30 mL/oz) + 240 mL (8 oz soup x 30 mL/oz) + 240 mL (8 oz coffee x 30 mL/oz) = 1440 mL total intake. The deficit is then calculated by subtracting the output from the intake: 1440 mL (intake) - 1000 mL (output) = 440 mL. This represents a net positive balance of 440 mL, often referred to as a deficit if the context implies a target or simply the difference.
