Question 1 of 5
The nurse is initiating a 500 mL IV of normal saline at 60 mL/hour for a client with heart failure. How many hours should the IV infuse? (Enter numeric value only. If rounding is required, round to the nearest tenth.)
Correct Answer: 8.3
Rationale: The correct answer is 8.3 hours.
To find the answer, we can use the following formula: (hours) = (mL of IV) / (mL/hour). Substituting the given values, we get: (hours) = (500) / (60). Simplifying, we get: (hours) = 8.333. (rounded hours) = 8.3.
Therefore, the IV should infuse for 8.3 hours.
Question 2 of 5
The healthcare provider prescribes enoxaparin 1 mg/kg subcutaneously every 12 hours for a client who weighs 132 pounds. The medication is available in 60 mg/0.6 mL prefilled syringe. How many mL should the nurse administer per day?(Enter numerical value only.)
Correct Answer: 1.2
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. Calculate the dose of enoxaparin in mg per administration by multiplying the weight in kg by the dosage in mg/kg. Divide the dose in mg per administration by the concentration of enoxaparin in the prefilled syringe in mg/mL. Multiply the volume in mL per administration by the number of administrations per day. Round the result to the nearest tenth. Using these steps, we get: (weight in kg) = (132) / (2.2) = 60 kg. (dose in mg per administration) = (1) x (60) = 60 mg. (volume in mL per administration) = (60) / (60 / 0.6) = 0.6 mL. (volume in mL per day) = (0.6) x (2) = 1.2 mL. (rounded volume in mL per day) = 1.2 mL.
Therefore, the nurse should administer 1.2 mL of enoxaparin per day.
Question 3 of 5
A patient is receiving a 200 mL bolus of 0.9% normal saline (NS) to be infused over 20 minutes. The nurse should set the infusion pump to deliver how many mL/hour?(Enter numeric value only.)
Correct Answer: 600
Rationale: The correct answer is 600 mL/hour.
To find the answer, we can use the following formula: (mL/hour) = (mL/minute) x 60. Substituting the given values, we get: (mL/hour) = (200 / 20) x 60. Simplifying, we get: (mL/hour) = 10 x 60. (mL/hour) = 600.
Therefore, the nurse should set the infusion pump to deliver 600 mL/hour of 0.9% NS to the patient.
Question 4 of 5
A client receives a prescription for 1 liter of lactated Ringer's intravenously (IV) to be infused over 8 hours. The IV administration set delivers 20 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: 42
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 / 8) x (20) / 60. Simplifying, we get: (gtt/min) = 125 x 20 / 60. (gtt/min) = 41.667. (rounded gtt/min) = 42.
Therefore, the nurse should regulate the infusion to deliver 42 gtt/minute of lactated Ringer's.
Question 5 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.
