A nurse is preparing to administer dextrose 5% in 0.45% sodium chloride 1000 mL to infuse at 100 mL/60 min. The drop factor on the manual IV tubing is 60 gtt/mL. The nurse should set the IV flow rate to deliver how many gtt/min?
(Round to the nearest whole number.)
The Correct Answer is ["1000"]
To calculate the IV flow rate in drops per minute (gtt/min), we can use the following formula: Flow rate (gtt/min) = Volume to be infused (mL) × Drop factor (gtt/mL) ÷ Time (min) Given information:
Volume to be infused = 1000 mL
Drop factor = 60 gtt/mL
Time = 60 min
Substituting the values into the formula:
Flow rate (gtt/min) = 1000 mL × 60 gtt/mL ÷ 60 min
Flow rate (gtt/min) = 1000 gtt/min
Therefore, the nurse should set the IV flow rate to deliver 1000 gtt/min.

Correct Answer is B
Explanation
Atenolol is a beta-blocker medication commonly used to treat conditions such as hypertension (high blood pressure) and certain heart rhythm disorders. One of the intended effects of atenolol is to lower the heart rate by blocking the action of adrenaline on beta receptors in the heart. However, this can sometimes result in bradycardia, which refers to a heart rate that is slower than the normal range.
Hypokalemia, or low potassium levels, is not directly caused by atenolol but can be an indirect effect. Beta-blockers like atenolol can potentially interfere with the normal release of insulin and contribute to increased urinary excretion of potassium. Therefore, it's important to monitor potassium levels in clients taking atenolol, as low potassium levels can have adverse effects on various body systems.
Anemia and neutropenia are not typically associated with the use of atenolol. Anemia refers to a decrease in the number of red blood cells or a decrease in the amount of hemoglobin, which carries oxygen to the body tissues. Neutropenia refers to a decrease in the number of neutrophils, which are a type of white blood cell involved in fighting infection.

Explanation
To calculate the infusion rate in drops per minute (gtt/min), we can use the following formula: Infusion rate (gtt/min) = (Volume to be infused (ml) * Drop factor) / Time (min) Given:
Volume to be infused: 1,200 ml
Drop factor: 15 gtt/ml
Time: 24 hr
First, we need to convert the time from hours to minutes:
24 hr * 60 min/hr = 1,440 min
Now, we can calculate the infusion rate:
Infusion rate (gtt/min) = (1,200 ml * 15 gtt/ml) / 1,440 min
Simplifying the equation:
Infusion rate (gtt/min) = 18,000 gtt / 1,440 min
Dividing both sides:
Infusion rate (gtt/min) ≈ 12.5 gtt/min
Rounding the answer to the nearest whole number, the nurse should set the manual IV infusion to deliver approximately 13 gtt/min.
