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?
Lead 18 mcg/dL.
Hemoglobin 12 g/dL.
Iron 74 mcg/dL.
Hematocrit 35%.
The Correct Answer is A
Choice A rationale:
A blood lead level of 18 mcg/dL in a 9-month-old infant is elevated. The Centers for Disease Control and Prevention (CDC) considers a blood lead level of 5 mcg/dL or higher in children to be concerning. Lead exposure can lead to developmental delays and cognitive impairments. Therefore, this result needs to be reported to the healthcare provider promptly.
Choice B rationale:
Hemoglobin level of 12 g/dL is within the normal range for a 9-month-old infant (11-15 g/dL) There is no need to report this result to the provider.
Choice C rationale:
Iron level of 74 mcg/dL is within the normal range for a 9-month-old infant (50-120 mcg/dL) There is no need to report this result to the provider.
Choice D rationale:
Hematocrit level of 35% is within the normal range for a 9-month-old infant (29-41%) There is no need to report this result to the provider.

Correct Answer is B
Explanation
Aspirate contents from the tube and verify the pH level.
- A. This is an incorrect action. Inserting air in the tube and listening for gurgling sounds in the epigastric area is not a reliable method to confirm NG tube placement, as it can produce falsepositive results due to air entering the stomach or intestines.
- B. This is a correct action. Aspirating contents from the tube and verifying the pH level is a valid method to confirm NG tube placement, as gastric contents typically have a pH of less than 5.5, while intestinal or respiratory contents have a higher pH.
- C. This is an incorrect action. Reviewing the medical record for previous x-ray verification of placement is not sufficient to confirm NG tube placement, as the tube can migrate or become dislodged after insertion. X-ray verification should be done initially and whenever there is doubt about the tube's position.
- D. This is an incorrect action. Auscultating the lungs for adventitious breath sounds is not a specific method to confirm NG tube placement, as it can indicate other conditions such as pneumonia or pulmonary edema. It can also miss signs of respiratory complications due to NG tube misplacement, such as pneumothorax or bronchial obstruction.
Correct Answer is A
Explanation
Choice A rationale:
The nurse should suggest, "Give your son a little gift from his new sister," as a strategy to help the preschool-age son adjust to having a new sibling. This approach involves a small token or gift given from the newborn to the older sibling. It helps create a positive association and fosters a sense of connection and acceptance between the siblings. The gift symbolizes the new baby's arrival and can help the older child feel special and valued during this transition.
Choice B rationale:
While spending alone time with the new sister is important, the statement, "Give your son plenty of 'alone time' with his sister," does not address the initial meeting concerns. Alone time is relevant once the siblings have established a bond, but the initial introduction requires a more structured approach to ensure a smooth transition.
Choice C rationale:
Planning for the son to meet his sister for the first time at home is not the most suitable strategy. Hospitals provide a controlled environment with healthcare professionals available, ensuring the safety and well-being of both the mother and the newborn. The initial meeting should occur in a setting where medical assistance is readily accessible in case of any unforeseen circumstances.
Choice D rationale:
Holding the daughter when the son first meets her is a common and natural practice but does not actively involve the son in the process. Providing a gift from the baby to the older sibling fosters a sense of participation and inclusion, making the older child feel more involved and excited about the new sibling's arrival.
