A nurse is preparing to administer cefazolin 1 g intermittent IV bolus in 0.9% sodium chloride 250 mL over 30 min. The drop factor on the manual V tubing is 10 gtt/ml. The nurse should set the manual IV flow rate to deliver how many gtt/min? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["83"]
To calculate the manual IV flow rate in drops per minute (gtt/min), you can use the following formula:
Flow rate (gtt/min) = (Volume to be infused in mL / Time in minutes) * Drop factor (gtt/mL)
Given:
- Volume to be infused = 250 mL
- Time in minutes = 30 minutes
- Drop factor = 10 gtt/mL
Now, plug these values into the formula:
Flow rate (gtt/min) = (250 mL / 30 min) * 10 gtt/mL
Flow rate (gtt/min) = (8.33) * 10
Flow rate (gtt/min) ≈ 83.3
Rounded to the nearest whole number, the nurse should set the manual IV flow rate to deliver approximately 83 gtt/min.

Correct Answer is ["2.3"]
Explanation
To calculate the amount of morphine (in mL) the nurse should administer, follow these steps:
Step 1: Convert the client's weight from pounds to kilograms. 99 lb / 2.2 lb/kg ≈ 45 kg (rounded to the nearest whole number)
Step 2: Calculate the total dose based on the client's weight. 0.1 mg/kg * 45 kg = 4.5 mg
Step 3: Determine how many mL of the available morphine solution (2 mg/mL) are needed to achieve the prescribed dose. 4.5 mg ÷ 2 mg/mL = 2.25 mL
Rounded to the nearest tenth, the nurse should administer 2.3 mL of morphine.
Correct Answer is ["2"]
Explanation
To determine how many tablets of sotalol the nurse should administer with each dose, you can use the following calculation:
Total daily dose / Number of doses per day = Dose per administration
In this case, the total daily dose is 320 mg, and it's divided into two doses per day.
320 mg / 2 doses = 160 mg per administration
Now, you know that the nurse should administer 160 mg of sotalol with each dose. The available tablets are 80 mg each, so you can calculate how many tablets are needed:
Dose per administration / Tablet strength = Number of tablets
160 mg / 80 mg/tablet = 2 tablets
Therefore, the nurse should administer 2 tablets of sotalol with each dose.
