10X = 5 X = 0.5 ml
A client's daily PO prescription for aripiprazole (Abilify) is increased from 15 mg to
30 mg. The medication is available in 15 mg tablets, and the client already
received one tablet today. How many additional tablets should the nurse
administer so the client receives the total newly prescribed dose for the day?
(Enter numeric value only.) - ANSWER-1
30 mg (total dose) - 15 mg (dose already administered) = 15 mg that still needs to
be administered. Using the Desired/Have formula: 15 mg/15 mg = 1 tablet
At the end of the shift, the nurse is recording the fluid balance for a client
receiving a continuous gastrostomy tube (GT) feeding. Based on the client's
records, how many ml should the nurse record for the total fluid balance (intake -
output) for the shift that started at 0700 and ended at 1900? (Enter numeric value
only.) (Click on each image asset for additional information.) - ANSWER-695
The tube feeding is administered at 75 ml/hour for 11 hours (0700 - 1800) and
then turned off for one hour because the residual is greater than 200 ml. 11 hours
x 75 ml/hr = 825 ml. Three doses of 20 ml of medication are administered, with 10
ml of water used to flush the GT before and after each dose. 20 ml x 3 doses = 60
ml; 10 ml (flush) x 2 x 3 doses = 60 ml; so 825 ml + 60 ml + 60 ml = 945 ml. 250 ml
of residual is removed and not replaced. 945 ml - 250 ml = 695 ml total fluid
balance (Intake - output).
The nurse is administering a 250 milliliter (ml) intravenous solution to be infused
over 2 hours. How many ml/hour should the nurse program the infusion pump?
(Enter numeric value only.) - ANSWER-125

250 ml : 2 hours = X ml : 1 hour 250 = 2X X = 250 divided by 2 = 125 ml/hr
The nurse is preparing to administer 0.25 mg of bumetanide (Bumex) IV. The
medication is available in a vial labeled 1 mg/4 ml. How many ml of medication
should the nurse administer? (Enter numeric value only.) - ANSWER-1
Using the Desired/Have x Volume formula: Desired = 0.25 mg Have = 1 mg Volume
= 4 ml 0.25 mg/1 mg x 4 ml = 1 ml
A client with hypertension receives a prescription for carteolol (Cartel) 7.5 mg PO
daily. The drug is available in 2.5 mg tablets. How many tablets should the nurse
administer? (Enter numeric value only.) - ANSWER-3
Using D/H: 7.5 mg / 2.5 mg = 3 tablets
The healthcare provider prescribes trimethoprim-sulfamethoxazole (Bactrim-DS
Oral Suspension) 120 mg BID for a child with bronchitis. The Bactrim bottle is
labeled 200 mg/5ml. How many ml should the nurse administer at each dose?
