What is the correct angle for giving an intradermal injection?

10 to 15 degrees

20 to 35 degrees

45 to 70 degrees

90 degrees

Answer and Explanation

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

To calculate the dose that the child receives, we need to first convert the volume of the suspension from teaspoons to milliliters. One teaspoon is equal to 5 milliliters, so 2 teaspoons is equal to 10 milliliters. Then, we can use the concentration of the suspension to find the amount of cefuroxime in 10 milliliters. The concentration is 25 mg in 2 mL, or 12.5 mg in 1 mL. Therefore, the amount of cefuroxime in 10 mL is:

10 mL × 12.5 mg/mL = 125 mg

Therefore, the child receives 125 mg of cefuroxime once a day orally.

A. 0.65 mL/hr B. 9.6 mL/hr C. 10.1 mL/hr D. 14.8 mL/hr

Correct Answer is C

Explanation

We can use the following formula to calculate the infusion rate:

Infusion rate (mL/hr) = (Dose ordered in mcg/min x Volume to be infused in mL) / Dose available in mg

First, we need to convert the dose ordered from mg/min to mcg/min: 125 mg = 125,000 mcg

125,000 mcg/500 mL = 250 mcg/mL

Now we can plug in the values we have into the formula:

Infusion rate (mL/hr) = (42 mcg/min x 60 min x 24 hours) / (250 mcg/mL) Infusion rate (mL/hr) = 10.08 mL/hr

Rounding to the nearest tenth, the answer is C. 10.1 mL/hr.

Therefore, the nurse should program the IV pump to deliver the nitroglycerin at a rate of 10.1 mL/hr to achieve the ordered dose of 42 mcg/minute.
