A nurse is administering an intradermal injection to a patient. Which statements are correct? Select all that apply.
A depressed area around the injection sites indicates a positive reaction.
After the insertion of the needle, a healthcare provider should aspirate for a blood return.
The needle is inserted with the bevel of the needle upward at a 10- to 15-degree angle.
The inner arm or upper back are the preferred sites.
Correct Answer : C,D
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.

Correct Answer is B
Explanation
This number should be multiplied by inches in order to convert a patient's height measurement from inches to centimeters, because one inch is equal to 2.54 centimeters. To convert inches to centimeters, the formula is:
centimeters = inches × 2.54
For example, if a patient's height is 60 inches, then the height in centimeters is:
centimeters = 60 × 2.54
centimeters = 152.4
Therefore, the patient's height is 152.4 centimeters.
Correct Answer is D
Explanation
To find the amount of solution to draw for one dose, you need to calculate the following:
- The body surface area (BSA) of the client in square meters (m²) using the formula: BSA (m²) = √(Height (cm) x Weight (kg) / 3600)
- The dose of allopurinol in milligrams (mg) using the formula: Dose (mg) = BSA (m²) x Prescribed dose
(mg/m²)
- The volume of solution in milliliters (mL) using the formula: Volume (mL) = Dose (mg) / Concentration (mg/mL)
First, use the formula for BSA to find the client's body surface area in square meters:
BSA (m²) = √(Height (cm) x Weight (kg) / 3600)
Since the client's height is 148 cm and weight is 55 kg, plug in these values into the formula:
BSA (m²) = √(148 cm x 55 kg / 3600)
Simplify and solve for the BSA:
BSA (m²) = 1.41 m²
Next, use the formula for dose to find the amount of allopurinol in milligrams:
Dose (mg) = BSA (m²) x Prescribed dose (mg/m²)
Since the client's BSA is 1.41 m² and the prescribed dose is 115 mg/m², plug in these values into the formula:
Dose (mg) = 1.41 m² x 115 mg/m²
Simplify and solve for the dose:
Dose (mg) = 162.15 mg
Then, use the formula for volume to find the amount of solution in milliliters:
Volume (mL) = Dose (mg) / Concentration (mg/mL)
Since the dose is 162.15 mg and the concentration is 25 mg/mL, plug in these values into the formula:
Volume (mL) = 162.15 mg / 25 mg/mL
Simplify and solve for the volume:
Volume (mL) = 6.486 mL
Therefore, the nurse should draw **6.486 mL** of solution for one dose of allopurinol.
