Question 1 of 5
A client with human immunodeficiency virus (HIV) begins active labor at 38 weeks gestation and receives a prescription for zidovudine 2 mg/kg IV, to be administered over 1 hour. The client weighs 185 lbs. Based on the client's weight, how many mg should the nurse prepare to administer? (Enter numerical value only. If rounding is required, round to the nearest whole number.)
Correct Answer: 168
Rationale:
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) = (185) / (2.2) = 84.091 kg. (dose in mg) = (2) x (84.091) = 168.182 mg. (rounded dose in mg) = 168 mg.
Therefore, the nurse should prepare to administer 168 mg of zidovudine IV to the client.
Question 2 of 5
A patient receives a prescription for hydrocortisone sodium succinate 150 mg intravenously STAT. The powdered medication needs to be reconstituted with 2 mL of bacteriostatic water that will provide a solution of 250 mg/mL. How many mL should the nurse administer?(Enter numerical value only.)
Correct Answer: 0.6
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) = (150) / (250). Simplifying, we get: (mL to be administered) = 0.6.
Therefore, the nurse should administer 0.6 mL of hydrocortisone sodium succinate to the patient.
Question 3 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 4 of 5
The healthcare provider prescribes lamivudine oral solution 150 mg twice daily for a client who is HIV positive. The available bottle contains 240 mL of lamivudine labeled, '10 mg/mL.' How many mL should the nurse administer in a 24 hour period?(Enter numeric value only.)
Correct Answer: 30
Rationale: The correct answer is 30 mL.
To find the answer, we can use the following steps: Calculate the total daily dose of lamivudine in mg by multiplying the dose per administration by the number of administrations. Divide the total daily dose of lamivudine in mg by the concentration of lamivudine in the oral solution in mg/mL. Round the result to the nearest whole number. Using these steps, we get: (total daily dose in mg) = (150) x (2) = 300 mg. (volume to be administered in mL) = (300) / (10) = 30 mL. (rounded volume to be administered in mL) = 30 mL.
Therefore, the nurse should administer 30 mL of lamivudine oral solution in a 24 hour period.
Question 5 of 5
The nurse is initiating a prescription for Dextrose 2.5% in 0.45% Sodium Chloride (D2.5W, 0.45% NS) at 45 mL/hour for a child with dehydration. The nurse attaches a volume-control administration set with a microdrip chamber to the bag of solution. How many microdrops/minute should the nurse regulate the infusion? (Enter the numerical value only. If rounding is required, round to the nearest whole number.)
Correct Answer: 45
Rationale:
To find the answer, we can use the following formula: (microdrops/minute) = (mL/hour) x (microdrops/mL) / 60. Substituting the given values, we get: (microdrops/minute) = (45) x (60) / 60. Simplifying, we get: (microdrops/minute) = 45.
Therefore, the nurse should regulate the infusion to deliver 45 microdrops/minute of Dextrose 2.5% in 0.45% Sodium Chloride.
