Question 1 of 5
A patient is to receive hydromorphone 1.5 mg IV push now. The medication comes in a prefilled syringe, 2 mg/mL. Identify how many milliliters the nurse will administer for this dose.
Correct Answer: 0.75 mL
Rationale:
To calculate: 2 mg/1 mL = 1.5 mg/x mL. Cross-multiply: (2 * x) = (1 * 1.5); 2x = 1.5; x = 1.5/2 = 0.75 mL.
Question 2 of 5
The nurse is giving an intradermal (ID) injection and will choose which syringe for this injection?
Correct Answer: B
Rationale: The proper size syringe for ID injection is a 1-mL tuberculin. The other syringes pictured are incorrect. Insulin syringes (marked in units) are not used for intradermal injections.
Question 3 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 4 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 5 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.
