Question 1 of 5
A patient with deep vein thrombosis (DVT) is receiving a continuous infusion of Heparin Sodium 20,000 Units in 5% Dextrose Injection 500 mL at the rate of 25 mL/hour. How many units of heparin should the client receive in 12 hours? (Enter numeric value only.)
Correct Answer: 1200
Rationale:
To find the answer, we can use the following formula: (units of heparin) = (mL/hour) x (hours) x (units per mL). Substituting the given values, we get: (units of heparin) = (25) x (12) x (20,000 / 500). Simplifying, we get: (units of heparin) = (25) x (12) x (40). (units of heparin) = 1200.
Therefore, the client should receive 1200 units of heparin in 12 hours.
Question 2 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 3 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 4 of 5
A patient is receiving a secondary infusion of vancomycin 1,500 mg in 250 mL to be infused over two hours. The IV administration set delivers 10 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: 21
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) = (250 / 2) x (10) / 60. Simplifying, we get: (gtt/min) = 125 x 10 / 60. (gtt/min) = 1250 / 60. (gtt/min) = 20.833. (rounded gtt/min) = 21.
Therefore, the nurse should regulate the infusion at 21 gtt/min.
Question 5 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.
