Question 1 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 2 of 5
The healthcare provider prescribed 2 liters of 5% Dextrose in water (D5W) to infuse in 24 hours. The IV administration set delivers 15 gtt/mL. How many mL/hour should the nurse program the infusion pump? (Enter numeric 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: (mL/hour) = (mL/minute) x 60. Substituting the given values, we get: (mL/hour) = (2000 / 24) x 60. Simplifying, we get: (mL/hour) = 83.333. (rounded mL/hour) = 83.
Therefore, the nurse should program the infusion pump to deliver 83 mL/hour of D5W.
Question 3 of 5
The healthcare provider prescribes ceftazidime 30 mg/kg/day for an infant weighing 3,500 grams. What dose should the nurse administer daily to this infant? (Enter numeric value only.)
Correct Answer: 105
Rationale:
To find the answer, we can use the following steps: Convert the infant's weight from grams to kilograms by dividing by 1000. Multiply the weight in kilograms by the dosage in mg/kg/day. Round the result to the nearest whole number. Using these steps, we get: (weight in kg) = (3,500) / (1000) = 3.5 kg. (dose in mg/day) = (30) x (3.5) = 105 mg/day. (rounded dose in mg/day) = 105 mg.
Therefore, the nurse should administer 105 mg of ceftazidime daily to this infant.
Question 4 of 5
The healthcare provider prescribes an IV bolus of diltiazem 0.25 mg/kg for a client with atrial fibrillation. The client weighs 178 pounds. How many mg should the nurse administer? (Enter numeric value only. If rounding is required, round to the nearest whole number.)
Correct Answer: 20
Rationale: The correct answer is 20 mg.
To find the answer, we can use the following steps: Convert the client's weight from pounds to kilograms by dividing by 2.2. Multiply the weight in kilograms by the dosage in mg/kg. Round the result to the nearest whole number. Using these steps, we get: (weight in kg) = (178) / (2.2) = 80.909 kg. (dose in mg) = (0.25) x (80.909) = 20.227 mg. (rounded dose in mg) = 20 mg.
Therefore, the nurse should administer 20 mg of IV diltiazem to the client.
Question 5 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.
