Question 1

A medical clinic purchases an x-ray machine at a cost of $26,990. After a deposit of $2,690, the balance is due in 54 equal monthly payments. Calculate the monthly payment.

Accepted Answer

The balance after the deposit is $26,990 - $2,690 = $24,300. Dividing this by 54 months gives a monthly payment of $450.

Question 2

Your health insurance premiums are $229 each month. How much will your insurance cost over a 9-month period?

Accepted Answer

To find the total cost of insurance over a 9-month period, we simply need to multiply the monthly premium by the number of months.

$229/month x 9 months = $2,061

Therefore, the correct choice is C.

Question 3

Find the prime factorization of the number 875.

Accepted Answer

The prime factorization of 875 can be found by dividing the number by its smallest prime factor and continuing the process with the quotient until only prime numbers are left. 875 can be divided by 5 (its smallest prime factor) to get 175. 175 can again be divided by 5 to get 35. 35 can be divided by 5 to get 7, which is a prime number. Therefore, the prime factorization of 875 is $5 \cdot 5 \cdot 5 \cdot 7$.

Question 4

Find all factors of the number 45.

Accepted Answer

To find the factors of 45, we need to find all the numbers that divide 45 exactly without leaving a remainder. The factors of 45 are 1, 3, 5, 9, 15, and 45, which are all listed in choice A. Choice B includes 25, which is not a factor of 45, and choice C includes 25 and 9, which are not factors of 45 either. Choice D includes only some of the factors of 45, and choice E includes 9, which is not a factor of 45. Therefore, choice A is the best choice.

Question 5

White blood cell (WBC) counts can indicate illness or infections. Before surgery, a patient's WBC count was 6,470; the day after surgery, it had risen to 12,781. What was the difference in the count before and after surgery?

Accepted Answer

The answer of White blood cell (WBC) counts can indicate...

Question 6

CNAs measure fluid intake and urine output of patients to help monitor their hydration. All fluids are measured in milliliters. 
a. A patient consumes 130 milliliters, 210 milliliters, 100 milliliters, and 150 milliliters of fluid at various times during the day. Find the total intake of fluids.
b. The nurse's aide measures 320 milliliters, 225 milliliters, and 70 milliliters of urine output for the same patient. Find the total output of fluids.
c. Which is greater: the total input or total output for the patient? By how many milliliters?

Accepted Answer

The answer of CNAs measure fluid intake and urine output...

Question 7

Simplify by using the Order of Operations Agreement. $40 - 2 \cdot 2 + ( 7 - 5 ) ^ { 3 }$

Accepted Answer

First, calculate the expression inside the parentheses: $7 - 5 = 2$. Then, raise it to the power of 3: $2^3 = 8$. Next, perform the multiplication: $2 \cdot 2 = 4$. Finally, perform the addition and subtraction from left to right: $40 - 4 + 8 = 44$.

Question 8

A local dentist office gives toothbrushes to its patients after each cleaning. A certain adult toothbrush is packaged 141 to a box and 18 boxes to a case. If the office manager orders two cases, how many toothbrushes are ordered?

Accepted Answer

Each case contains 18 boxes, and each box contains 141 toothbrushes. Therefore, 2 cases contain 2 * 18 * 141 = 5,076 toothbrushes.

Question 9

Find all factors of the number 225.

Accepted Answer

Factors are the numbers that can divide the given number without leaving a remainder. So, we can find the factors of 225 by dividing 225 by all the numbers from 1 to 225 and listing those that divide without a remainder. The factors of 225 are 1, 3, 5, 9, 15, 25, 45, 75, and 225 itself. Out of the given choices, option C lists all the correct factors. Option B is a close choice and could be confusing, but it misses including the factor 225. Option A lists numbers higher than 225, which is not possible as they cannot be factors of 225. Option D lists additional numbers that are not factors of 225. Option E misses out on higher factor numbers such as 25, 45, 75, and 225.
