Question 1

A physician ordered 1 L of dialysate solution, per each cycle or exchange of peritoneal dialysis. After the prescribed "dwell" time, $3/ 4$   of the solution (fluid plus waste products) drained. How many milliliters of solution remained in the patient's abdomen?
A) 125
B) 250
C) 500
D) 750

Accepted Answer

If $3/4$ of the 1 L solution drained, $1/4$ remained. $1/4$ of 1 L (1000 mL) is 250 mL.

Question 2

A patient/client was directed to take 8 oz of MiraLAX solution as bowel prep for a colonoscopy. The MiraLAX powder was mixed in 64 oz of Gatorade. The client drank 8 oz every 15 minutes for six doses. Two doses remained. How many milliliters of MiraLAX solution remained?
A) 240
B) 300
C) 360
D) 480

Accepted Answer

Use the following equivalent, 1 oz = 30 mL, to work in the same liquid measure. The patient/client drank 48 oz of MiraLAX (8 oz × 6 doses) from a 64-oz container. To estimate the amount of solution remaining, subtract the amount of solution already taken (48 oz) from the total amount available (64 oz), which equals 16 oz. Then, multiply the remaining ounces by the equivalent: 30 mL = 1 oz. Therefore, 30 mL × 16 oz = 480 mL.

Question 3

A physician prescribed 10 mg of an antibiotic per kilogram of body weight for a patient/client who weighs 165 lb. How many kilograms does the patient/client weigh? How many grams per kilogram would the nurse give?
A) 70; 0.001
B) 75; 0.01
C) 80; 0.1
D) 85; 1

Accepted Answer

Use two equivalents: 1 kg = 2.2 lb and 1 g = 1000 mg. To convert pounds to kilograms, divide by 2.2 and round to the nearest tenth. Therefore, 165 lb / 2.2 = 75 kg. When you move from a smaller quantity (milligrams) to a larger quantity (grams), divide or move the decimal three places to the left. To convert 10 mg to grams, move the decimal point three places to the left: 0.01 g. The Quick Method for changing milligrams to grams is to write the equivalent that you need, show which way the decimal point should move by drawing an arrow, make sure the open part of the arrow always faces the larger measure, and remember that 1 g = 1000 mg; the gram is the larger measure (1000 mg < x g). The arrow directs moving the decimal point three places to the left (10 mg = 0.01 g).

Question 4

A physician prescribed 15 mL of a drug per kilogram for a 66-lb child. How many kilograms should the nurse use to estimate dosage? How many ounces per kilogram would the nurse give?
A) 30; 0.5
B) 35; 1
C) 40; 1.5
D) 45; 2

Accepted Answer

Use two equivalents: 1 kg = 2.2 lb and 30 mL = 1 oz. To convert pounds to kilograms, divide by 2.2 and round to the nearest tenth. Therefore, 66 lb ÷ 2.2 = 30 kg. To convert milliliters to ounces, divide by 30. Therefore, 15 mL ÷ 30 mL = 0.5 oz.

Question 5

A patient/client was told to take 2 tablespoons of Robitussin (dextromethorphan) syrup, twice daily, to relieve his cough. The patient/client was told that this dosage was equivalent to how many ounces?
A) 0.5
B) 1
C) 1.5
D) 2

Accepted Answer

Use the equivalent: 1 tablespoon = 15 mL. Multiple 2 tablespoons × 15 mL = 30 mL. Use the equivalent: 30 mL = 1 ounce.

Question 6

The patient/client is to receive 0.05 mg of liquid Lanoxin (Digoxin) once daily. What is the dosage of this medication in micrograms?
A) 0.5 mcg
B) 5 mcg
C) 50 mcg
D) 500 mcg

Accepted Answer

When you move from a larger quantity (milligrams) to a smaller quantity (micrograms), multiply or move the decimal three places to the right. To convert 0.05 mg to micrograms, move the decimal point three places to the right, which equals 50 mcg. The Quick Method for changing milligrams to micrograms is to write the equivalent that you need, show which way the decimal point should move by drawing an arrow, make sure the open part of the arrow always faces the larger measure, and remember that 1 mg = 1000 micrograms; the milligram is the larger measure (1 mg > x mcg). The arrow directs moving the decimal point three places to the right (0.05 mg = 50 mcg).

Question 7

The patient/client is to receive 250 mg of Augmentin (amoxicillin/clavulanate potassium) po, twice daily. Augmentin (amoxicillin/clavulanate potassium) is available as 125 mg/ 5 mL. How many teaspoons of the medication would the patient/client take for one dose?
A) 0.5 teaspoon
B) 1 teaspoon
C) 1.5 teaspoons
D) 2 teaspoons

Accepted Answer

The patient/client took 250 mg of Augmentin. If 125 mg = 5 mL then 250 mg = 10 mL. The patient/client took 10 mL of Augmentin. Use the following equivalent: 5 mL = 1 teaspoon; 10 mL = 2 teaspoons.

Question 8

A patient/client weighed 50 kg on day seven of his hospitalization. The nurse noted that this was a loss of five pounds since admission. The nurse would document a current patient/client weight of how many pounds? What was the patient/client's weight, in kilograms, on admission?
A) 103; 44.5
B) 110; 52.3
C) 113; 49.1
D) 120; 52.3

Accepted Answer

Use the equivalent: 1 kg = 2.2 lb. To convert kilograms to pounds, multiply by 2.2 and round to the nearest tenth: 50 kg × 2.2 = 110 lbs. Next, add 5 lb to current weight of 110 lb = 115 lb as admission weight. . To convert pounds to kilograms, divide by 2.2 and round to the nearest tenth: 115 ÷ 2.2 = 52.3 kg.

Question 9

A patient/client was prescribed Vitamin B₁₂, 2500 mcg, sublingually, daily. At the end of seven days, the patient will have taken how many milligrams of Vitamin B₁₂? A) 7.5 B) 12.5 C) 17.5 D) 22.5

Accepted Answer

The Quick Method for changing micrograms to milligrams is to write the equivalent that you need, show which way the decimal point should move by drawing an arrow, make sure the open part of the arrow always faces the larger measure, and remember that 1 mg = 1000 mcg. The milligram is the larger measure (2500 mcg < x mg). The arrow directs moving the decimal point three places to the left (2500 mcg = 2.5 mg). Next, multiply 2.5 mg × 7 days = 17.5 mg.

Question 10

A patient/client, on a fluid-restricted diet, is directed to take his daily medications with 120 mL of water. The patient/client will use a measuring cup and pour how many ounces of water?
A) 2
B) 3
C) 4
D) 5

Accepted Answer

Use the equivalent: 1 oz = 30 mL. To estimate the number of ounces in 120 mL: 120 mL ÷ 30 mL, = 4 ounces.
