An RPN is administering an IM injection to an adult patient. Which is the preferred site for a large-volume IM injection?
Answer: Ventrogluteal site
The ventrogluteal site is preferred for large-volume IM injections in adults because it is free of major nerves and blood vessels.
Which of the following is an example of a pharmacokinetic drug interaction?
Answer: One drug altering the metabolism of another drug in the liver
Pharmacokinetic interactions involve one drug altering the absorption, distribution, metabolism, or excretion of another drug.
A nurse must administer 250 mg of a medication available as 125 mg/5 mL. How many mL should be administered?
Answer: 10 mL
Using the formula: (desired dose ÷ available dose) × volume = (250 ÷ 125) × 5 = 10 mL.
When using the Z-track technique for IM injection, what is the primary purpose?
Answer: Prevent leakage of irritating medication into subcutaneous tissue
The Z-track technique seals the medication in the muscle by displacing the skin and subcutaneous tissue, preventing irritating drugs from tracking back through the needle path.
A patient on digoxin reports nausea, visual disturbances, and seeing yellow-green halos. The nurse's priority action is to:

Which action is required when wasting a controlled substance that was not fully administered?
Answer: Document the amount wasted and have a second nurse witness and co-sign
Controlled substance wasting must be witnessed and co-signed by a second authorized nurse to ensure accountability and prevent diversion.
The nurse is applying a transdermal nitroglycerin patch. Which instruction to the patient is most important?
