A nurse is discussing the Z-track administration of hydroxyzine with a newly licensed nurse. Which of the following statements indicates the newly licensed nurse understands the purpose of the technique?
"This technique prevents injury to the sciatic nerve."
"This technique decreases the risk of subcutaneous infiltration."
"This technique allows a larger amount of medication to be injected."
"This technique increases the absorption rate of the drug.”
The Correct Answer is B
A. "This technique prevents injury to the sciatic nerve.": The Z-track method is not designed to prevent nerve injury. Proper site selection and injection technique address nerve safety, but the Z-track specifically targets tissue leakage, not nerve protection.
B. "This technique decreases the risk of subcutaneous infiltration.": The Z-track technique displaces the skin and subcutaneous tissue before intramuscular injection, creating a zigzag path that seals the medication in the muscle. This prevents leakage into subcutaneous tissue, reducing irritation and ensuring proper absorption.
C. "This technique allows a larger amount of medication to be injected.": The Z-track does not affect the volume that can be safely administered; it is intended to prevent leakage and irritation, not to increase injection capacity.
D. "This technique increases the absorption rate of the drug.": Z-track injections do not increase the absorption rate; they maintain the drug in the muscle, preventing subcutaneous irritation and ensuring proper medication delivery without affecting pharmacokinetics.

Correct Answer is D
Explanation
A. Insert an indwelling catheter if the client has not voided in 3 hr: Inserting an indwelling catheter involves an invasive procedure and requires clinical judgment and assessment for contraindications such as coagulopathy, which is common in acute liver failure. This task should remain with the registered nurse (RN) rather than being delegated to an LPN.
B. Obtain the abdominal girth now and every 4 hr: Measuring abdominal girth is a repetitive, non-invasive monitoring task that is within the scope of practice of assistive personnel. The RN should delegate this task to the AP, allowing the LPN to perform tasks requiring slightly higher clinical skills.
C. Assess and document the level of consciousness every hour: Assessing neurological status requires ongoing clinical judgment and the ability to detect subtle changes in mental status, which is critical in clients with hepatic encephalopathy. This responsibility cannot be delegated and must be performed by the RN.
D. Measure the amount of gastric drainage every 2 hrs: Monitoring and documenting the amount of NG tube drainage is within the scope of practice for an LPN. It requires basic assessment skills, accurate measurement, and reporting changes to the RN, making it appropriate to delegate to the LPN.
Correct Answer is C
Explanation
A. Arterial blood gases: ABGs assess acid-base balance and respiratory status, which are not directly affected by lithium therapy. They are not required prior to initiating lithium.
B. Total cholesterol: Lithium does not significantly impact lipid metabolism, so baseline cholesterol is not necessary before starting therapy.
C. Thyroid hormones: Lithium can affect thyroid function and may cause hypothyroidism over time. Evaluating baseline thyroid hormone levels prior to therapy helps monitor for potential adverse effects and guides ongoing management.
D. Hemoglobin: Lithium does not directly affect hemoglobin levels, so baseline hemoglobin measurement is not required for safe initiation of therapy.
