Chapter 9 Questions
Question 1 of 5
A patient is to receive a penicillin intramuscular (IM) injection in the ventrogluteal site. The nurse will use which angle for the needle insertion?
Correct Answer: D
Rationale: The proper angle for IM injections is 90 degrees to ensure the medication reaches the muscle layer. The other angles are incorrect for IM administration.
Question 2 of 5
When administering medication by IV bolus (push), the nurse will occlude the IV line by which method?
Correct Answer: B
Rationale: Occluding the IV line by pinching the tubing just above the injection port prevents backflow and ensures the medication is delivered correctly during an IV bolus. The other methods are incorrect.
Question 3 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 4 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 5 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.
