Question 1 of 5
A child with a seizure disorder receives a prescription for phenytoin 20 mg by mouth every 8 hours. The suspension is available in 125 mg/5 mL. How many mL should the nurse administer?(Enter the numerical value only. If rounding is required, round to the nearest tenth.)
Correct Answer: 0.8
Rationale:
To find the answer, we can use the following formula: (mL to be administered) = (mg prescribed) / (mg per mL). Substituting the given values, we get: (mL to be administered) = (20) / (125 / 5). Simplifying, we get: (mL to be administered) = (20) x (5 / 125). (mL to be administered) = 0.8.
Therefore, the nurse should administer 0.8 mL of phenytoin suspension to the child.
Question 2 of 5
The healthcare provider prescribes liraglutide 1.2 mg subcutaneously daily for a client with type 2 diabetes mellitus. The liraglutide Pen contains 18 mg of liraglutide and will deliver doses of 0.6 mg, 1.2 mg, or 1.8 mg. When teaching the client about the use of the liraglutide Pen, how many doses should the nurse tell the client is available in each Pen? (Enter the numerical value only.)
Correct Answer: 15
Rationale:
To find the answer, we can use the following formula: (number of doses) = (amount of liraglutide in Pen) / (dose of liraglutide prescribed). Substituting the given values, we get: (number of doses) = (18) / (1.2). Simplifying, we get: (number of doses) = 15.
Therefore, the nurse should tell the client that each liraglutide Pen contains 15 doses of liraglutide.
Question 3 of 5
A client receives a prescription for 1 liter of lactated Ringer's intravenously (IV) to be infused over 12 hours. The IV administration set delivers 60 gtt/mL. How many gtt/min should the nurse regulate the infusion?(Enter numerical value only. If rounding is required, round to the nearest whole number.)
Correct Answer: 83
Rationale:
To find the answer, we can use the following formula: (gtt/min) = (mL/hour) x (gtt/mL) / 60. Substituting the given values, we get: (gtt/min) = (1000 / 12) x (60) / 60. Simplifying, we get: (gtt/min) = 83.333. (rounded gtt/min) = 83.
Therefore, the nurse should regulate the infusion to deliver 83 gtt/minute of lactated Ringer's.
Question 4 of 5
Filgrastim 5 mcg/kg/day subcutaneous is prescribed for a child with cancer who weighs 88 pounds. The medication is labeled 300 mcg/mL. How many mL should the nurse administer daily to this child?(Enter the numerical value only. If rounding required, round to the nearest tenth.)
Correct Answer: 0.7
Rationale:
To find the answer, we can use the following steps: Convert the child's weight from pounds to kilograms by dividing by 2.2. Calculate the dose of filgrastim in mcg by multiplying the weight in kg by the dosage in mcg/kg/day. Divide the dose in mcg by the concentration of filgrastim in mcg/mL. Round the result to the nearest tenth. Using these steps, we get: (weight in kg) = (88) / (2.2) = 40 kg. (dose in mcg) = (5) x (40) = 200 mcg. (volume in mL) = (200) / (300) = 0.667 mL. (rounded volume in mL) = 0.7 mL.
Therefore, the nurse should administer 0.7 mL of filgrastim to this child daily.
Question 5 of 5
A client who weighs 60 kg receives a prescription for dalteparin 200 units/kg subcutaneously once a day for a month. The medication is available in 25,000 units/mL vial. How many mL should the nurse administer?(Enter numerical value. If rounding is required, round to the nearest tenth.)
Correct Answer: 0.5
Rationale:
To find the answer, we can use the following steps: Calculate the dose of dalteparin in units by multiplying the weight in kg by the dosage in units/kg. Divide the dose in units by the concentration in units/mL. Round the result to the nearest tenth. Using these steps, we get: (dose in units) = (60) x (200) = 12,000 units. (volume in mL) = (12,000) / (25,000) = 0.48 mL. (rounded volume in mL) = 0.5 mL.
Therefore, the nurse should administer 0.5 mL of dalteparin from the vial to the client.
