A nurse is preparing to administer 1 L of 0.9% sodium chloride solution to a client over 6 hours. The intravenous (IV) fluid has a drop factor of 15 gt/mL. What will be the gt/min flow rate?
41.6 gt/min
0.2 gt/min
2.7 gt/min
24 gt/min
The Correct Answer is A
To calculate the gt/min flow rate, we need to determine the total number of drops and divide it by the total time in minutes.
First, let's convert the volume from liters to milliliters:
1 L = 1000 mL
Next, we need to determine the total number of drops. This can be calculated using the drop factor and the volume of the solution:
Total drops = Volume (mL) * Drop factor
= 1000 mL * 15 gt/mL
= 15000 gt
Now, we need to calculate the flow rate in gt/min. We divide the total drops by the total time in minutes: Flow rate = Total drops / Total time (min)
= 15000 gt / 360 min
≈ 41.67 gt/min (rounded to the nearest whole number)
Therefore, the correct answer is:
a. 41.6 gt/min

Correct Answer is A
Explanation
To find how much medication to administer, you need to calculate the following:
- The volume of diphenhydramine in milliliters
- The infusion time in minutes
First, divide the dose of diphenhydramine by the concentration to get the volume in milliliters:
25 mg / 50 mg/mL = 0.5 mL diphenhydramine should be diluted in 10 to 20 mL of normal saline and infused over at least 2 minutes.
Therefore, the nurse should administer **0.5 mL** of diphenhydramine diluted in 10 to 20 mL of normal saline over **at least 2 minutes**.
The nurse should administer this medication **as soon as possible** after receiving the order and the medication from the pharmacy, as STAT means immediately or urgently. The nurse should also monitor the client for signs of improvement or adverse reactions.
Correct Answer is B
Explanation
The correct angle for giving an intradermal injection is **10 to 15 degrees**. This angle allows the needle to enter the dermis, which is the layer of skin just below the epidermis. The needle should be inserted almost flat against the patient's skin, with the bevel side up. A small blister or bleb should form under the skin after injecting the medication.
