The healthcare provider has ordered 1000 mL of 0.9% sodium chloride to be administered intravenously over 5 hours. The drop factor on the tubing is 15 drops/mL. How many milliliters per hour will you administer and how many drops per minute?
250 mL/hr and 45 drops/min
200 mL/hr and 45 drops/min
200 mL/hr and 50 drops/min
250 mL/hr and 50 drops/min
The Correct Answer is C
To calculate the rate of administration in milliliters per hour (mL/hr):
First, find the total volume to be infused: 1000 mL
Next, divide the total volume by the total time in hours: 1000 mL ÷ 5 hours = 200 mL/hr
Therefore, you will administer the solution at a rate of 200 mL/hr.
To calculate the rate of administration in drops per minute (drops/min):
First, find the total drops: 1000 mL × 15 drops/mL = 15,000 drops
Next, divide the total drops by the total time in minutes: 15,000 drops ÷ (5 hours × 60 minutes/hour) = 50 drops/min
Therefore, you will administer the solution at a rate of 200 mL/hr and 50 drops/min.

Correct Answer is B
Explanation
A. Chronic diarrhea: Overuse of laxatives is more likely to cause chronic constipation rather than chronic diarrhea. While some types of laxatives can lead to diarrhea as a side effect, chronic diarrhea is less common with laxative overuse compared to chronic constipation.
B. Chronic constipation
When the smooth muscle in the colon loses its tone due to overuse of laxatives, it can lead to chronic constipation. Laxatives work by stimulating bowel movements, but frequent or excessive use can lead to dependency and decreased natural bowel function. Over time, the colon may become less responsive to normal stimuli, resulting in difficulty passing stool and chronic constipation.
C. Frequent vomiting: Overuse of laxatives is not directly associated with frequent vomiting. Vomiting can occur as a result of various gastrointestinal issues, but it is not a typical consequence of laxative overuse.
D. Chronic nausea: While gastrointestinal symptoms such as nausea may occur as a side effect of some laxatives, chronic nausea is not a common consequence of laxative overuse. It is more likely to result from other underlying medical conditions or gastrointestinal disturbances.
Correct Answer is ["10"]
Explanation
To administer the correct dose of amoxicillin, the nurse needs to calculate the volume of suspension that contains the prescribed dose of 500 mg.
Since the available suspension has a concentration of 250 mg per 5 ml, the nurse can calculate the required volume using the formula: (prescribed dose/concentration) x volume of concentration = required volume.
Plugging in the numbers: (500 mg / 250 mg) x 5 ml = 2 x 5 ml = 10 ml.
Therefore, the nurse should administer 10 ml of the amoxicillin suspension to deliver a dose of 500 mg.
