A nurse is preparing to administer potassium chloride 40 mEq in dextrose 5% in 0.9% sodium chloride 1,000 mL IV to infuse over 8 hr. The tubing has a drop factor of 15 gtt/mL.
The nurse should set the 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 ["31"]
To calculate the IV flow rate in drops per minute (gtt/min), we can use the following steps:
Calculate the total number of minutes for the infusion:
8 hours × 60 minutes/hour = 480 minutes
Determine the total number of drops needed for the infusion:
The total volume to be infused is 1000 mL.
The drop factor is 15 gtt/mL.
1000 mL × 15 gtt/mL = 15000 gtt
Calculate the IV flow rate in drops per minute:
15000 gtt ÷ 480 min ≈ 31 gtt/min
Rounding to the nearest whole number, the nurse should set the IV flow rate to deliver 31 gtt/min.

Correct Answer is ["125"]
Explanation
To calculate the rate at which the nurse should set the IV pump to deliver dextrose 5% in 0.45% sodium chloride over 24 hours, we can use the following steps:
Given:
Total IV fluid volume: 3 L
Infusion duration: 24 hours
Step 1: Convert the total IV fluid volume from liters (L) to milliliters (mL)
Total volume = 3 L × 1000 mL/L
Total volume = 3000 mL
Step 2: Calculate the rate of infusion per hour
Rate = Total volume / Infusion duration
Rate = 3000 mL / 24 hr
Rate ≈ 125 mL/hr
Rounding to the nearest whole number:
Rate ≈ 125 mL/hr
Therefore, the nurse should set the IV pump to deliver approximately 125 mL/hr for the infusion of dextrose 5% in 0.45% sodium chloride over 24 hours.
Correct Answer is C
Explanation
Choice A reason: This is incorrect. INR level is a measure of blood clotting time and is not directly affected by digoxin. It is more relevant for patients who are taking anticoagulants, such as warfarin.
Choice B reason: This is incorrect. Temperature is not a priority assessment for a patient receiving digoxin. It may indicate an infection or inflammation, but it is not related to the action or toxicity of digoxin.
Choice C reason: This is correct. Apical heart rate is the priority assessment for a patient receiving digoxin. Digoxin is a cardiac glycoside that increases the force and efficiency of the heart contractions, but also slows down the heart rate. The nurse should monitor the apical pulse for one full minute before administering digoxin and withhold the dose if the pulse is below 60 beats per minute for adults or below the age-specific normal range for children. A low or irregular pulse may indicate digoxin toxicity, which can be life-threatening.
Choice D reason: This is incorrect. Blood pressure is not a priority assessment for a patient receiving digoxin. Digoxin does not have a direct effect on blood pressure, although it may improve the cardiac output and reduce the fluid retention in patients with heart failure. Blood pressure should be monitored regularly, but it is not as critical as the apical heart rate.
