hours for an adult client experiencing pain associated with maxillofacial surgery. The
bottle is labeled 500 mg/15 ml. How many ml should the nurse administer? (Enter

A client who has AIDS is receiving octreotide (Sandostatin) 1,200 mcg by subcutaneous
injection every day for symptoms of diarrhea. Octreotide is available for injection in 1
mg/ml vials. How many ml should the nurse administer? (Enter numeric value only. If
rounding is required, round to the nearest tenth.) - correct answer1 or 1.2
First, to convert micrograms to milligrams, divide the number of micrograms by 1000:
1,200/1000 = 1.2 mg. Using the Desired/Have available formula: 1.2 mg/1 mg x 1 ml =
1.2 ml.
A client is receiving dantrolene sodium (Dantrium) PO for malignant hyperthermia. The
maximum safe dose is 8 mg/kg/day in 4 divided doses. The client currently weighs 48.5
kg. What is the maximum safe dose the nurse should administer? (Enter numeric value
only. If rounding is required, round to the nearest whole number.) - correct answer97
, Determine the maximum number of mg this client should receive in a day: 48.5 kg x 8
mg/kg/day = 388 mg/day. Next determine how many mg the nurse should deliver each

A child with a urinary tract infection is receiving Cephalexin (Keflex) 100 mg suspension
PO QID. Keflex oral suspension is labeled 125 mg in 5 ml. How many ml should the

A client returns to the nursing unit from surgery with a prescription for Lactated Ringer's
solution 1,000 ml to be infused over 10 hours. The IV administration set delivers 60
gtts/ml. The nurse should regulate the infusion to deliver how many gtts/minute? -
correct answer100
First convert hours to minutes: 10 hrs x 60 = 600 minutes. Using the formula
Volume/Time x drop factor: 1000 ml /600 minutes = 1.66666 x 60 = 100 gtts minute.
