Question 1 of 5
The nurse has an order to administer an intramuscular (IM) immunization to a 2-month-old child. Which site is considered the best choice for this injection?
Correct Answer: D
Rationale: The vastus lateralis is the preferred site for IM injections in infants due to its adequate muscle mass and lack of major nerves or blood vessels. The deltoid is used for older children and adults, the dorsogluteal site is not recommended due to nerve injury risk, and the ventrogluteal is preferred for adults and older children.
Question 2 of 5
The nurse needs to administer insulin subcutaneously to an obese patient. Which is the proper technique for this injection?
Correct Answer: C
Rationale: For subcutaneous injections in obese patients, pinching the skin and inserting the needle at a 90-degree angle ensures delivery into the subcutaneous tissue. The Z-track method is for IM injections, a 5- to 15-degree angle is incorrect, and spreading the skin is not appropriate for subcutaneous administration.
Question 3 of 5
The nurse will plan to use the Z-track method of intramuscular (IM) injections for which situation?
Correct Answer: A
Rationale: The Z-track method is used for medications that irritate tissues or cause staining, preventing leakage into subcutaneous tissues. It is not specifically for emaciated or obese patients or for rapid absorption.
Question 4 of 5
After administering an intradermal (ID) injection for a skin test, the nurse notices a small bleb at the injection site. Which of these is the best action for the nurse to take at this time?
Correct Answer: C
Rationale: A small bleb is an expected outcome after an intradermal injection for skin testing, indicating proper administration. No further action is needed.
Question 5 of 5
The nurse is administering an IV push medication through an IV lock. After injecting the medication, which action will be taken next?
Correct Answer: A
Rationale: Flushing the IV lock with saline or heparin (per facility policy) after administering an IV push medication ensures the medication is cleared from the lock and prevents clotting. The other actions are not appropriate.
