A client with pericardial effusion has phrenic nerve compression
resulting in recurrent hiccups. The healthcare provider prescribes
metoclopramide (Reglan) liquid 10 mg PO q6 hours. Reglan is available
as 5 mg/5 ml. A measuring device marked in teaspoons is being used.
How many teaspoons should the practical nurse administer?
Answer- 2
First, using the formula, Desired dose/dose on Hand x Quantity of
volume on hand (D/H x Q),
10 mg / 5 mg x 5ml = 10 ml
Next using the known conversion of 5 ml = 1 tsp:
5 ml: 1 tsp: 10 ml: X
: 1 / X
5X = 10
,X=2
A client who has a sinus infection is receiving a prescription for
amoxicillin/clavulanate potassium (Augmentin) 500 mg PO q8 hours.
The available form is 250 mg amoxicillin/125mg clavulanate tablets.
How many tablets should the practical nurse administer for each dose?
(Enter numeric value only.)
Answer- 2
Using the known equivalent, 1 gram = 1000 mg, the nurse should first
convert the dose to the same unit of measurement, which is 1 gram =
1000 mg.
Using the formula, Desired / Available x 1 tablets:
1000 mg / 500 mg x 1 = 2 tablets
A client with type 2 diabetes is receiving metformin (Glucophage) 1-
gram PO twice daily. The medication is available in 500 mg tablets.
How many tablets should the practical nurse administer? (Enter numeric
value only.)
,Answer- 2
Using the known equivalent, 1 gram = 1000 mg, the nurse should first
convert the dose to the same unit of measurement, which is 1 gram =
1000 mg.
Using the formula, Desired / Available x 1 tablets:
1000 mg / 500 mg x 1 = 2 tablets
A client with a gastrostomy tube (GT) receives a prescription for
Osmole 1/2 strength enteral formula at 80 ml/hour. To prepare a 4-hour
solution, the PN should dilute the full-strength formula with how many
ml of water? (Enter numeric value only.)
Answer- 160
Determine the total volume needed at 80 ml/hour x 4 hours = 320 ml.
Use the formula, Desired strength/strength on Hand x Volume = 50/100
x 320 = 160 ml of Osmole enteral formula, which must be diluted to half
strength.
, Or use ratio and proportion, Desired strength (1/2 = 1 part: 2 parts):
Volume of full strength: Total Desire volume
1: 2: X: 320 ml
2X = 320, and X = 160 ml of Osmole enteral formula, full strength
320 ml total volume - 160 ml of full-strength formula = 160 ml of water
to create 1/2 strength or 50% concentration
A client who weighs 70 pounds receives a prescription for phenytoin
(Dilantin) PO. The practical nurse (PN) refers to the published drug
literature which recommends the dose of 10 mg/kg/day. How many mgs
should the PN determine is the recommended dose for this client? (Enter
numerical value only. If rounding is required, round to the nearest whole
number.)
Answer- 318
2.2 pounds = 1 kg, so 70 pounds = 31.8181 kg31.8181 x 10 mg/1 kg/day
= 318.181 or 318 mg/day
