Question 1

A client's nasogastric tube was inserted 56 centimeters and was taped to the nose.Currently the tape marking is 40 millimeters from the nose.How many centimeters of the nasogastric tube remains in the client?

Accepted Answer

cm = 1 cm/10 mm x 40 mm/1.Multiply the numerators (1 x 40 = 40).Multiply the denominators (10 x 1 = 10).40/10 = 4 cm.56 cm - 4 cm = 52 centimeters remains in the client.

Question 2

The nurse is caring for a newborn who weighs 2,650 g.How many kilograms does the newborn weigh?
Standard Text: Round the answer to the nearest tenth.
____ kg

Accepted Answer

2.7 kg
Explanation:kg = 1 kg/1000 g x 2650 g/1.Multiply the numerators (1 x 2650 = 2650).Multiply the denominators (1000 x 1 = 1000).2650/1000 = 2.65 = 2.7 kg.

doses per bottle= 1 dose/ 4 T x 2 T/ 1 ounce x 16 ounces/1 bottle.Multiply the numerators (1 x 2 x 16 = 32).Multiply the denominators (4 x 1 x 1 = 4).32/4 = 8 doses per 1 bottle.

Question 4

The home care nurse reviews the following medication order for a client: Take 2 t ampicillin oral suspension every 6 hours.How many T of the medication will the client take in 1 day?

Accepted Answer

T/day = 1 T/3 tsp x 2 tsp/6 hrs x 24 hrs/1 day.Multiply all the numerators (1 x 2 x 24 = 48).Multiply all the denominators (3 x 6 x 1 = 18).48/18 = 2.66.Household measurements use fractions,not decimals.Convert 0.66 into a fraction by placing 66/100 which reduces to 2/3;therefore,the answer is 2 2/3 T will be taken each day.

Question 5

During a daily weight the nurse notes that a client has lost 0.4 kilograms.How many grams of weight should the nurse document that this client has lost in one day?

Accepted Answer

First add up the total volume of intake in mL or 120 + 240 + 240 + 80 + 500 = 1180 mL.Once you have done this,use dimensional analysis to solve the problem.L/shift = 1 L/1000mL x 1180 mL/1 shift.Multiply the numerators (1 x 1180 = 1180).Multiply the denominators (1000 x 1 = 1000).1180/1000 = 1.18 L.

Question 9

A client diagnosed with multiple sclerosis (MS)is prescribed 30 mcg of interferon beta - 1a by injection once a week.How many milligrams of Avonex will the patient receive in one week?

Question 10

A client is prescribed to receive ½ cup of a dietary supplement 3 times a day.How many Tablespoons of the supplement will the client be taking each day?

Accepted Answer

T/day = 2 T/1 ounce x 8 ounces/1 cup x 0.5 cups/8 hours x 24 hours/1 day.Multiply the numerators (2 x 8 x 0.5 x 24 = 192).Multiply the denominators (1 x 1 x 8 x 1 = 8).192/8 = 24 T/day.

Question 11

The nurse measures a school-age child as being 111 cm in height.The previous measurement was 108 cm.How many millimeters in height has the child grown between examinations?

Accepted Answer

The difference in height between office visits is 111 - 108 = 3 cm.mm = 10 mm/1 cm x 3 cm/1.Multiply the numerators (10 x 3 = 30).Multiply the denominators (1 x 1 = 1).30/1 = 30 cm.

Question 12

A client is prescribed clarithromycin (Biaxin)500 mg PO every 6 hours for 10 days.How many grams of the medication will the client take during the full course of the antibiotic?

Accepted Answer

g = 1 g/1000 mg x 500 mg/6 hrs x 24 hrs/1 day x 10 days/1.Multiply the numerators (1 x 500 x 24 x 10 = 120,000).Multiply the denominators (1000 x 6 x 1 x 1 = 6,000).120,000/6,000 = 20 grams in 10 days.

Question 13

The nurse is preparing to administer natalizumad,300 mg IV.The medication is administered 1 time per month.How many grams of medication will the client receive in 3 months?
