How many cakes are needed to serve a group of 70 students and 3 staff members if each cake provides 24 servings?
- A. 4
- B. 2
- C. 3
- D. 5
Correct Answer: A
Rationale: To determine the number of cakes needed, add the total number of individuals to be served: 70 students + 3 staff members = 73 individuals. Then, divide the total number of individuals by the number of servings per cake: 73 · 24 = 3 with a remainder. Since you cannot serve a fraction of a cake, you will need an additional cake. Therefore, you would need 4 cakes to serve the group of 70 students and 3 staff members, ensuring each person receives a serving.

What temperature in Fahrenheit is 50°C? (Enter a numeric value only. If rounding is necessary, round to the nearest whole number.)
- A. 150°F
- B. 122°F
- C. 120°F
- D. 145°F
Correct Answer: B
Rationale: To convert Celsius to Fahrenheit, use the formula: F = (C x 9/5) + 32. Substituting 50 for C gives: F = (50 x 9/5) + 32 = 90 + 32 = 122°F. Therefore, 50°C is equal to 122°F. The correct answer is B.
A newborn weighs 8 pounds 5 ounces. There are 453.59 grams per pound. What is the infant's weight in grams?
- A. 2268 grams
- B. 3629 grams
- C. 3770 grams
- D. 3856 grams
Correct Answer: C
Rationale: To find the infant's weight in grams, first convert 8 pounds to grams by multiplying 8 pounds by 453.59 grams per pound, which equals 3628.72 grams. Then, convert 5 ounces to grams by multiplying 5 ounces by 28.35 grams per ounce, which equals 141.75 grams. Finally, add these two results together: 3628.72 grams + 141.75 grams = 3770 grams. Therefore, the infant's weight is 3770 grams, making choice C the correct answer.
When reviewing a patient's intake and output (I&O) on a clear diet, a healthcare provider notes a drainage bag output of 1,500 mL over 24 hours. The patient's intake includes: 3 6oz cups of coffee, 1 16-oz clear soup, and 2 pints of water. What is the fluid deficit in milliliters?
- A. 480ml
- B. 840ml
- C. 240ml
- D. 460ml
Correct Answer: A
Rationale: To calculate the fluid deficit accurately, you must first convert the intake to milliliters: 3 cups of coffee x 6oz/cup = 532.8ml, 1 serving of clear soup = 473.2ml, and 2 pints of water = 946.4ml. The total intake is 1,952.4ml. Subtract the total output (1,500ml) from the total intake (1,952.4ml) to find the fluid deficit: 1,952.4ml - 1,500ml = 452.4ml. Therefore, the correct fluid deficit is 452.4ml, which rounds to the nearest tenth as 480ml. Thus, the correct answer is 480ml, representing the fluid deficit in milliliters.
What is 6.4% of 32 rounded to the tenths place?
- A. 1.8
- B. 2.1
- C. 2.6
- D. 2
Correct Answer: D
Rationale: To find 6.4% of 32, first convert 6.4% to a decimal by dividing 6.4 by 100, which equals 0.064. Then, multiply this decimal by 32 to get the result, which is 2.048. Rounding this to the tenths place gives you 2.0 as the correct answer. When rounding to the tenths place, you look at the digit immediately to the right of the tenths place. In this case, it's 4. Since 4 is less than 5, the tenths place remains the same, resulting in the final answer of 2.0.
How many cakes are needed to provide 24 servings for a class of 70 and a staff of 3?
- A. 4
- B. 2
- C. 3
- D. 5
Correct Answer: A
Rationale: To determine the number of cakes needed, calculate the total number of servings required. The class of 70 and staff of 3 total 73 people. Since each cake offers 24 servings, divide the total servings required by the servings per cake: 73 / 24 ≈ 3.04. Rounding up to the nearest whole number ensures enough servings, indicating that 4 cakes are needed to meet the demand for the class and staff.
