A nurse is reviewing the results of laboratory screenings for a 9-month-old infant. Which of the following results should the nurse report to the provider?
Hemoglobin 12 g/dL
Iron 74 mcg/dL
Lead 18 mcg/dL
Hematocrit 35%
The Correct Answer is C
A. A hemoglobin level of 12 g/dL is within the expected range for an infant.
B. An iron level of 74 mcg/dL is normal for a 9-month-old.
C. This is the correct answer. A lead level of 18 mcg/dL is elevated (≥5 mcg/dL is concerning) and should be reported, as lead toxicity can lead to neurological damage.
D. A hematocrit of 35% is within the expected range for an infant.

Correct Answer is D
Explanation
A. Close the doors and windows on the unit – While containing the fire is important, it is not the first priority. Activating the fire alarm ensures facility-wide response and safety protocols.
B. Activate the fire alarm system – This is the first action because it alerts emergency responders and allows evacuation protocols to begin. Timely activation prevents the fire from spreading and ensures prompt intervention.
C. Obtain and use a fire extinguisher – Fire extinguishers are used only for small, contained fires and should be handled by trained personnel after activating the alarm.
D. Evacuate clients from the area – While evacuation is critical, activating the fire alarm ensures a coordinated evacuation plan rather than causing panic.
Correct Answer is D
Explanation
A. Place the client on an air mattress – While air mattresses help prevent pressure ulcers, they do not directly address mobility needs in the immediate postoperative period.
B. Rewrap the bandage every 8 hr in a circular pattern – The bandage should be reapplied more frequently (every 4–6 hr) using a figure-eight pattern to prevent restriction of circulation.
C. Turn the client every 4 hr while in bed – Clients should be turned at least every 2 hr to prevent pressure ulcers and improve circulation.
D. Instruct the client to use an overbed trapeze to move around in bed – This is the best intervention because it allows the client to reposition independently, reducing the risk of skin breakdown and enhancing mobility.
