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 B
Explanation
A. 3 months: At 3 months, infants typically have a smaller head circumference, weigh less (around 12–13 lb), have fewer teeth, and have not yet demonstrated standing or significant weight-bearing when held. The developmental milestones observed in this infant exceed those expected at 3 months.
B. 6 months: The infant’s weight (14.5 lb), height (24 inches), presence of two lower central incisors, ability to bear weight when held in a standing position, hold a bottle, and exhibit a social smile align with typical developmental milestones for a 6-month-old. Neurologic reflexes such as Moro and tonic neck reflexes usually disappear by this age.
C. 9 months: By 9 months, infants are usually able to sit without support, may begin crawling, and have more teeth. The inability to sit unsupported indicates the infant is younger than 9 months.
D. 12 months: At 12 months, infants generally are able to stand independently, may begin walking, and have more advanced fine motor skills and additional teeth. The developmental abilities and physical measurements of this infant suggest she is younger than 12 months.
Correct Answer is B
Explanation
A. Wear a mask while in the room with the toddler: Varicella (chickenpox) is transmitted via airborne and contact routes. Standard precautions include contact and airborne precautions, so an N95 or fitted mask is required rather than a simple mask.
B. Wipe the stethoscope with an alcohol-based gel after use: Cleaning equipment that comes into contact with the client helps prevent the spread of infection. Alcohol-based disinfectants effectively reduce transmission of varicella from shared medical equipment.
C. Place the toddler in a room with positive-pressure airflow: Positive-pressure rooms are used for immunocompromised clients to prevent pathogens from entering. Airborne precautions for varicella require a negative-pressure room to prevent spreading the virus to others.
D. Schedule the toddler for private time in the playroom: Allowing a child with varicella in communal areas risks spreading the virus to susceptible children. The toddler should remain in isolation until lesions crust over.
