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 C
Explanation
The correct answer is choice C, 3 tablets. To calculate the number of tablets, divide the ordered dose by the available dose:
75 mg ÷ 25 mg = 3
The nurse should administer 3 tablets of Coumadin 25 mg to the patient to give a total dose of 75 mg.
Correct Answer is D
Explanation
The toddler is ordered to receive 25 mg/kg of Principen IV over 30 minutes. The toddler weighs 22 lb, which is equivalent to 10 kg. To calculate the total amount of Principen the toddler should receive, multiply the weight by the dosage:
10 kg x 25 mg/kg = 250 mg
The Principen dose arrives from the pharmacy prepared in 50 mL of IV solution, which means there is 250 mg of Principen in 50 mL of solution. To calculate how many milliliters per hour the nurse should administer, we can use the following formula:
50 mL / 0.5 hour = X mL per hour X = 100 mL per hour
Therefore, the nurse should administer 100 mL of Principen per hour to the toddler.
