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 B
Explanation
To calculate the infusion rate in mL/hr, we need to divide the total volume to be infused by the time for infusion and convert the units appropriately.
First, we need to convert the time of infusion from hours to minutes, since most IV pumps use minutes as the time unit.
2 hours x 60 minutes/hour = 120 minutes Next, we can calculate the infusion rate:
500 mL ÷ 120 minutes = 4.17 mL/minute
To convert mL/minute to mL/hour, we multiply by 60:
4.17 mL/minute x 60 minutes/hour = 250 mL/hour
Therefore, the correct answer is B. 250 mL/hr. The nurse should set the IV pump to deliver the LR infusion at a rate of 250 mL/hr to infuse 500 mL over 2 hours.
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.
