During shift report the nurse is told that there is 450 mL left in a client's IV and it has to run for 2 more hours.
If the drip factor is 15 gtt/mL what is the current IV rate?
The Correct Answer is ["56"]
Step 1 is: Calculate the total minutes the IV needs to run. 2 hours × 60 minutes/hour = 120 minutes.
Step 2 is: Calculate the mL/minute rate. 450 mL ÷ 120 minutes = 3.75 mL/minute.
Step 3 is: Calculate the gtt/minute rate. 3.75 mL/minute × 15 gtt/mL = 56.25 gtt/minute. The current IV rate is 56 gtt/minute.

Correct Answer is ["1.9"]
Explanation
Step 1 is to determine the concentration of the reconstituted medication. The vial contains 4g and is reconstituted with 12mL for a final concentration of 2g per 2.5mL.
Step 2 is to calculate how many mL are needed for the 1.5g dose. The desired dose is 1.5g. The concentration is 2g in 2.5mL.
Step 3 is to set up a proportion: (2g ÷ 2.5mL) = (1.5g ÷ X mL).
Step 4 is to solve for X: X mL = (1.5g × 2.5mL) ÷ 2g.
Step 5 is to calculate the value: X = 3.75 ÷ 2.
Step 6 is to calculate the final answer: X = 1.875 mL.
Step 7 is to round to the nearest tenth: 1.9 mL. The final calculated answer is 1.9 mL.
Correct Answer is ["9"]
Explanation
Step 1 is: Heart rate 120 BPM = 2 points (HR > 100 BPM).
Step 2 is: Strong cry = 2 points (Strong cry/cough).
Step 3 is: Well-flexed = 2 points (Well flexed).
Step 4 is: Reflex-crying = 2 points (Cry/sneeze).
Step 5 is: Body pink; acrocyanosis present in hands and feet = 1 point (Body pink, extremities blue).
Step 6 is: Add up all the points: 2 + 2 + 2 + 2 + 1 = 9.
Answer: 9.
