A nurse is preparing to administer an intradermal injection for a client who requires a tuberculin skin test. What actions should the nurse plan to take?

Place a 1-inch needle on the syringe.

Hold the syringe at a 20° angle to the client’s skin.

Draw up 0.5 mL of purified protein derivative (PPD) from the vial.

Pinch the skin at the chosen site with the non-dominant hand before inserting the needle.

Answer and Explanation

The Correct Answer is C

Choice A rationale
Placing a 1-inch needle on the syringe is not appropriate for an intradermal injection such as a tuberculin skin test. Intradermal injections require a much shorter needle, typically 1/4 to 1/2 inch in length.
Choice B rationale
Holding the syringe at a 20° angle to the client’s skin is not correct for an intradermal injection. For an intradermal injection, the syringe should be held at a much shallower angle, typically about 5 to 15 degrees.
Choice C rationale

Drawing up 0.1 mL of purified protein derivative (PPD) from the vial is the correct action when preparing to administer a tuberculin skin test. This is the standard amount of PPD used for a tuberculin skin test.
Choice D rationale
Pinching the skin at the chosen site with the non-dominant hand before inserting the needle is not typically done for an intradermal injection. Instead, the skin is usually stretched taut to provide a flat surface for the injection.

Correct Answer is D

Explanation

Choice A rationale
While antibiotics are used to treat bacterial infections, crackles in the lungs can be a sign of various conditions, not just bacterial infections. Therefore, administering antibiotics is not the appropriate action based solely on the finding of crackles.
Choice B rationale

Limiting fluid intake can be beneficial for clients with certain conditions such as heart failure, but it is not the appropriate action based solely on the finding of crackles.
Choice C rationale
Initiating bedrest in semi-Fowler’s position can help improve lung expansion and ease breathing in clients with certain respiratory conditions. However, it is not the appropriate action based solely on the finding of crackles.
Choice D rationale
Crackles can sometimes be cleared by deep breathing and coughing. Repeating the auscultation after asking the client to breathe deeply and cough can help the nurse determine if the crackles are transient (cleared by coughing) or persistent.

A. 5 mL B. 6 mL C. 7 mL D. 8 mL

Correct Answer is C

Explanation

Step 1 is to calculate the amount of amoxicillin in milliliters. Step 2: We know that 250 mg of amoxicillin is in 5 mL.
Step 3: We need to find out how many mL contain 350 mg of amoxicillin. Step 4: Set up a proportion: 250 mg/5 mL = 350 mg/x mL.
Step 5: Cross-multiply and solve for x: 250x = 1750. Step 6: Divide both sides by 250: x = 7 mL2.
