A nurse is reviewing the laboratory results of four children. Which value should the nurse report to the provider?
Iron 38 mcg/dL.
RBC 4.9 million/mm.
WBC 10,000 cells/mm.
Lead 2 mcg/dL.
None
None
The Correct Answer is A
The correct answer is Choice A
Choice A rationale: Serum iron levels in children typically range from 50 to 120 mcg/dL. A value of 38 mcg/dL is significantly below the lower limit, indicating possible iron deficiency. Iron is essential for hemoglobin synthesis, oxygen transport, and cognitive development. Deficiency can lead to microcytic anemia, fatigue, and developmental delays. Early detection is critical, especially in pediatric populations where growth and neurodevelopment are rapid. This abnormal value warrants prompt provider notification for further evaluation and intervention.
Choice B rationale: Normal red blood cell (RBC) count in children ranges from approximately 4.1 to 5.5 million/mm³. A value of 4.9 million/mm³ falls comfortably within this range and does not suggest anemia or polycythemia. RBC count reflects bone marrow function and oxygen-carrying capacity. In the absence of symptoms or abnormal hemoglobin levels, this value is considered physiologically appropriate and does not require provider notification. It supports adequate erythropoiesis and oxygenation in the pediatric patient.
Choice C rationale: White blood cell (WBC) count in children typically ranges from 5,000 to 10,000 cells/mm³. A value of 10,000 cells/mm³ is at the upper limit of normal and may reflect mild physiological variation, such as recent activity or minor stress. It does not indicate infection, inflammation, or hematologic disorder unless accompanied by clinical symptoms or abnormal differential counts. Therefore, this value is not considered pathologic and does not require immediate reporting to the provider.
Choice D rationale: Blood lead levels below 5 mcg/dL are considered acceptable by CDC standards, although no level is truly safe. A value of 2 mcg/dL is within the expected range and does not indicate acute toxicity or environmental exposure requiring intervention. Lead affects neurological development, but levels under 5 mcg/dL are generally monitored without urgent action. Continued surveillance and environmental precautions are advised, but this value does not necessitate immediate provider notification.

Correct Answer is A
Explanation
Choice A rationale
Engaging in conversation with the patient during wound care can provide emotional support by distracting the patient from the pain and discomfort associated with the procedure. It also helps to build a therapeutic relationship, which is crucial in the healing process.
Choice B rationale
While ensuring the patient’s room is kept tidy by support staff is important for maintaining a clean and safe environment, it does not directly provide emotional support to the patient.
Choice C rationale
Keeping the patient’s family informed about his condition can provide reassurance and reduce anxiety, but it does not directly provide emotional support to the patient.
Choice D rationale
Rotating the nursing staff can provide the patient with varied interactions, but it may not necessarily provide emotional support. Consistency in care providers can often be more beneficial in building trust and rapport.
Correct Answer is C
Explanation
Choice A rationale
Streptococcal pharyngitis, also known as strep throat, is a bacterial infection that causes inflammation and pain in the throat. This condition is spread through respiratory droplets, not through the air, and does not require airborne precautions.
Choice B rationale
Scabies is caused by a mite infestation, not an airborne pathogen. It is spread through direct skin-to-skin contact and does not require airborne precautions.
Choice C rationale
Measles is a highly contagious virus that lives in the nose and throat mucus of an infected person. It can spread to others through coughing and sneezing, and the measles virus can live for up to two hours in an airspace where the infected person coughed or sneezed. Therefore, a patient with measles requires airborne precautions.
Choice D rationale
Pertussis, also known as whooping cough, is a highly contagious respiratory disease caused by the bacterium Bordetella pertussis. It spreads through close contact with respiratory droplets when an infected person coughs or sneezes. It is typically managed with droplet precautions, not airborne precautions.
