COLLECTION
◉ A 110-pound, adult female is admitted to the Emergency Center
after receiving burns to 40 percent of her body. Using the Parkland
formula, the client's fluid requirements for the first 24 hours after
injury is calculated using Lactated Ringer's 4 ml solution x Body
weight (in kilograms) x Percent burn. The client should receive one-
half of the 24-hour calculated fluid volume in the first 8 hours of
treatment. The nurse should set the infusion pump to deliver how
many ml/hour during the first 8 hours? (Enter the numerical value
only. If rounding is required, round to the nearest whole number.)
Answer: Using the Parkland formula, the client's fluid requirements
for the first 24 hours after injury is calculated using 4 ml lactated
Ringer's solution x Body weight (in kilograms) x Percent burn
Convert 110 pounds to kg = .2 = 50 kg
4 ml x 50 kg x 40 = 8,000 ml
One-half in first 8 hours = 4,000 ml
4,000 ml / 8 hours = 500 = 500 ml/hour
, ◉ A client who has heart failure with paroxysmal atrial tachycardia
is receiving digoxin (Lanoxin) 0.45 mg IV as the inital digitalizing
dose. The pharmacy provides 0.25 mg/ml. How many ml should the
nurse administer? (Enter numeric value only. If rounding is required,
round to the nearest tenth.)
Answer: Using the formula D/H x Q = 0.45 mg/0.25 mg x 1 mL = 1.8
ml
◉ Mineral oil U.S.P 30 ml PO daily for 3 days is prescribed for a
client who is experiencing severe constipation. The dose cup is
marked in tablespoons. How many tablespoons should the nurse
administer? (Enter numeric value only.)
Answer: 15 ml equals 1 Tablespoon. Use the ratio equation: 15 ml : 1
Tbs :: 30 ml : X
:: 1 / X
15X = 30
X = 2 Tablespoons
◉ A client is receiving an IV solution of 2 grams of medication
diluted in 100 ml of normal saline over a one hour time period. How
many mg of medication is the client receiving per minute? (Enter
numeric value only. If rounding is required, round to the nearest
whole number.)
Answer: 2 grams = 2000 mg
1 hour = 60 minutes
