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.
The Correct Answer is D
The correct answer is Choice A
Choice A rationale: Iron 38 mcg/dL is below the normal range for children (50-120 mcg/dL). Low iron levels can indicate iron deficiency anemia, which requires medical evaluation and intervention to prevent complications such as developmental delays and decreased immunity.
Choice B rationale: RBC 4.9 million/mm is within the normal range for children (4.0-5.5 million/mm). This value does not indicate any abnormalities and does not require reporting to the provider. RBC count helps in assessing the overall red blood cell health and oxygen-carrying capacity.
Choice C rationale: WBC 10,000 cells/mm is within the normal range for children (5,000-10,000 cells/mm). This value is considered normal and does not indicate an infection or other condition needing immediate attention. WBC count is critical for evaluating the immune system's response to infection.
Choice D rationale: Lead 2 mcg/dL is within the acceptable range for children. The Centers for Disease Control and Prevention (CDC) considers lead levels less than 5 mcg/dL to be acceptable. Lead exposure can harm children's development, but this level does not necessitate immediate reporting

Correct Answer is D
Explanation
Choice A rationale
Lubricating the suction catheter tip with sterile saline is not recommended because it can introduce bacteria into the tracheostomy tube and cause infection.
Choice B rationale
Hyperventilating the patient on 100% oxygen prior to suctioning is not necessary and can cause complications such as oxygen toxicity.
Choice C rationale
Performing chest physiotherapy prior to suctioning is not typically done during tracheostomy care. Chest physiotherapy is a separate procedure that involves physical techniques to remove mucus from the respiratory tract.
Choice D rationale
Suctioning two to three times with a 60-second pause between passes is the correct action. This helps to remove secretions effectively without causing hypoxia.
Correct Answer is A
Explanation
Choice A rationale
Cleaning the catheter after each use with soap and water is a crucial step in preventing infection during self-catheterization.
Choice B rationale
The angle at which the penis should be held during catheter insertion can vary, but a 30 to 45- degree angle is not typically recommended.
Choice C rationale
Performing catheterization when feeling the urge to void is not typically part of the instructions for clean intermittent self-catheterization.
Choice D rationale
Inflating the balloon when the urine flow stops is not a step in clean intermittent self- catheterization. This step is associated with indwelling catheters, not intermittent catheters.
