What is the correct angle for giving an intradermal injection?
10 to 15 degrees
20 to 35 degrees
45 to 70 degrees
90 degrees
The Correct Answer is A
According to the web, intradermal injections are administered into the dermis just below the epidermis at a 5 to 15 degree angle12 This angle allows for smooth piercing of the skin and induction of the medication into the dermis.
Option B (20 to 35 degrees) is incorrect because it is too steep for an intradermal injection and may cause the medication to enter the subcutaneous layer instead of the dermis.
Option C (45 to 70 degrees) is incorrect because it is too steep for an intradermal injection and may cause the medication to enter the subcutaneous layer instead of the dermis.
Option D (90 degrees) is incorrect because it is too steep for an intradermal injection and may cause the medication to enter the muscle layer instead of the dermis.

Correct Answer is D
Explanation
A. 0.04 mg
-
This is far too small.
-
It might come from a miscalculation involving the concentration (1 mg/mL) and volume (5 mL), but incorrectly dividing again by 100.
-
Not clinically reasonable because the patient would barely receive any drug.
B. 0.25 mg
-
This is also incorrect.
-
It could result from mistakenly dividing 5 mg by 20 minutes instead of 2 minutes.
-
Again, far below the actual ordered rate.
C. 3.75 mg
-
This is incorrect but closer.
-
It might come from a misstep like subtracting 1.25 mg from the correct answer (2.5 mg) or misusing the concentration.
-
Still not the right calculation.
D. 2.5 mg
-
Correct answer.
-
Direct calculation: 5 mg ÷ 2 minutes = 2.5 mg/min.
-
Matches the ordered dose and administration time.
Correct Answer is A
Explanation
First, we need to convert the weight of the child from pounds to kilograms:. 99 lb / 2.2046 = 44.91 kg (rounded to two decimal places).
Next, we can calculate the dose of carmustine:. 25 mg/kg x 44.91 kg = 1,122.75 mg.
We should always check our calculation and verify that the dose is appropriate and safe for the child. In this case, the dose of 1,122.75 mg seems reasonable for a child with Hodgkin disease..
Since the medication is prescribed daily, the nurse should administer the calculated dose of 1,122.75 mg of carmustine to the child every day.
