Deck 6: Basic Review of Mathematics

Question 1

The physician recommends a teenager start taking 600 mg ibuprofen (Advil) tid, starting 2 days before her menstrual cycle and that she continue the medication for one week. The medication comes in 200-mg strength tablets. How many tablets will the patient consume during the week?

Answer 1

63 tablets
Tablets consumed in 1 week = 600 mg divide by 200 mg = 3 tablets per dose
3 tablets per dose 3 times daily = 9 tablets each day; 9 tablets per day x 7 days = 63 tablets

Question 2

A young girl is started on 5 mg of paroxetine (Paxil) daily. The pharmacy provides 10-mg tablets. How many tablets will the nurse provide?

Answer 2

1/2 tablet
Tablets to provide = 1 tablet has 10 mg, each dose needs 5 mg, to get 5 mg, the nurse will give 1/2 tablet

Question 3

While caring for a patient on a 1,700-calorie diet restriction, the nurse notes the patient has consumed 415 calories for breakfast. If 300 calories are allotted for beverages and snacks, how many calories remain for the patient's meals?

Answer 3

985 calories
Total calories remaining = 1,700
1,700 - 415 - 300 = 985 calories remaining for the patient's meals

Question 4

The nurse is caring for a patient who takes lisinopril (Zestril) 10 mg tid. Discharge orders include a prescription for a 30-day supply. How many pills will be in the bottle when the prescription is filled?

Question 5

A patient consumes 1/2 cup grape juice, 2/3 of a 10 oz bowl of broth, 1/4 of a 4 oz bowl of gelatin, and a 1/3 carton of milk, which holds 240 mL. Calculate the patient's intake in mL.

Question 6

While assisting with meal planning for a patient placed on an 1,800-calorie diet, the nurse plans for meals to make up 80% of the calorie consumption and wants to make each meal equivalent. How many calories should the nurse plan for each of three meals?

Question 7

The nurse is providing ondansetron (Zofran) 4 mg as an intravenous injection. The pharmacy provides ondansetron in 8 mg/2 mL vials. How many mL of medication will the nurse draw up?

Question 8

While working in the pediatric clinic, the nurse receives a call from a patient trying to figure out how much infant acetaminophen (Tylenol) to give to her child. The doctor has prescribed 45 mg every 4 hours. The medication is provided in a 60 mg/5 mL concentration. How much medication (in mL) should the patient provide per dose? Round to the nearest tenths place. (Rounding to the full mL would give the child too much medication.)

Question 9

The nurse is caring for a patient placed on a 2,000-calorie diet. If two snacks are responsible for 20% of the caloric intake, how many calories can be consumed with each snack?

Question 10

The nurse is caring for a patient on peritoneal dialysis. During a dialysis session, 2,000 mL of dialysate solution was infused and 1,850 mL returned. The patient consumed 1 cup of coffee, 120 mL of apple juice, and 1 bowl of oatmeal without milk. Calculate the patient's intake in mL.
