A nurse is administering an intravenous (IV) infusion of 2 g cefotaxime dissolved in 100 mL of isotonic glucose solution to a client. The drop factor of the IV tubing is 15 drops/mL.
If the infusion time is 1 hr, what is the gt/min?

These statements are correct because they follow the guidelines for intradermal injections, which are used for skin testing, such as for allergies or tuberculosis. Intradermal injections are given into the dermis, which is the layer of skin below the epidermis.
The needle is inserted with the bevel of the needle upward at a 10- to 15-degree angle to ensure that the medication is delivered into the dermis and not into the subcutaneous tissue or the epidermis. The bevel is

the slanted part of the needle tip that creates a sharp point. Inserting the needle with the bevel upward also reduces tissue trauma and bleeding.
The inner arm or upper back are the preferred sites for intradermal injections because they have thin skin and minimal hair, which makes it easier to see and measure any reactions. The inner arm is usually used for adults, while the upper back is used for children.
The other statements are not correct because they do not apply to intradermal injections or they contain false information.

a. A depressed area around the injection sites indicates a positive reaction. This statement is false because a depressed area, also known as induration, indicates a negative reaction. A positive reaction is indicated by a raised area, also known as a wheal, that is larger than a certain size depending on the type of test.

b. After the insertion of the needle, a healthcare provider should aspirate for a blood return. This statement does not apply to intradermal injections because aspiration is not necessary for this type of injection. Aspiration is the process of pulling back on the plunger of the syringe to check for blood in the needle before injecting the medication. This is done to avoid injecting into a blood vessel, which can cause adverse effects or reduce the effectiveness of the medication. However, intradermal injections are given into very superficial layers of skin where there are no blood vessels, so aspiration is not required.

First, we need to convert the patient's weight from pounds to kilograms using the conversion factor 1 kg =

2.2 lb:

154 lb / 2.2 lb/kg = 70 kg

Next, we need to calculate the dose of nitroprusside in mcg/min using the formula Dose = Weight × Dosage:

Dose = 70 kg × 3 mcg/kg/min = 210 mcg/min

Then, we need to convert the dose of nitroprusside from mcg/min to mg/hr using the conversion factor 1 mg = 1000 mcg:

210 mcg/min × 1 mg/1000 mcg × 60 min/hr = 12.6 mg/hr

Finally, we need to calculate the rate of nitroprusside in mL/hr using the formula Rate = Dose/Concentration:

Rate = 12.6 mg/hr / 100 mg/mL = 0.126 mL/hr

To round to the nearest hundredth, we get 0.13 mL/hr, which is approximately equal to 1.26 mL/hr.

Therefore, the nurse should program the IV pump to deliver nitroprusside at a rate of 1.26 mL/hr.
