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.

The rationale for each choice is as follows:
- A. Irritability: Correct. Irritability is one of the signs of hypoglycemia, which occurs when blood glucose levels fall below 70 mg/dL (3.9 mmol/L). Other signs include shakiness, sweating, hunger, headache, confusion, and blurred vision.
- B. Increased urination: Incorrect. Increased urination is one of the signs of hyperglycemia, which occurs when blood glucose levels rise above 180 mg/dL (10 mmol/L). Other signs include thirst, dry mouth, fatigue, nausea, and fruity breath odor.
- C. Vomiting: Incorrect. Vomiting is not a specific sign of hypoglycemia or hyperglycemia, but it can occur as a complication of either condition if left untreated or poorly managed.
- D.Facial flushing: Incorrect. Facial flushing is not a sign of hypoglycemia or hyperglycemia, but it can occur as a side effect of some medications used to treat diabetes, such as niacin or rosiglitazone.
Correct Answer is ["A","B","C","D"]
Explanation
- A: Correct. Firmly massaging the uterine fundus helps to contract the uterus and reduce bleeding.
- B: Correct. Providing emotional support helps to calm the client and reduce anxiety, which can worsen bleeding.
- C: Correct. Administering oxygen helps to improve tissue perfusion and oxygenation, which can be compromised by blood loss. Weighing the perineal pads helps to quantify the amount of blood loss and monitor for hemorrhage.
- D: Correct. Inserting an indwelling urinary catheter helps to empty the bladder and allow the uterus to descend and contract more effectively. Administering methylergonovine helps to stimulate uterine contractions and control bleeding.
- E: Incorrect. Administering terbutaline is contraindicated in this situation, as it relaxes the uterine smooth muscle and increases bleeding.
