A nurse is reviewing the laboratory report of a preschooler during a well-child visit. Which of the following laboratory results should the nurse report to the provider?
Iron 100 mcg/dL.
Hemoglobin 8 g/dL.
Sodium 140 mEq/L.
Calcium 9 mg/dL.
The Correct Answer is B
Choice A rationale:
Iron 100 mcg/dL The normal range for serum iron levels can vary based on age and gender, but typically, a range of 50 to 150 mcg/dL is considered normal. The provided value of 100 mcg/dL falls within this range and is not a cause for concern. Elevated iron levels can be indicative of hemochromatosis or other disorders, but this value is not concerning.
Choice B rationale:
Hemoglobin 8 g/dL Hemoglobin levels can vary by age and gender, but in general, a hemoglobin level of 8 g/dL is low and suggestive of anemia, a condition characterized by a reduced ability of the blood to carry oxygen. Anemia can lead to fatigue, weakness, and other symptoms, and the nurse should report this finding to the healthcare provider for further evaluation and management.
Choice C rationale:
Sodium 140 mEq/L The normal range for serum sodium levels is typically around 135 to 145 mEq/L. The provided value of 140 mEq/L falls within this normal range and is not a cause for concern. Deviations from this range can indicate various conditions, including dehydration or overhydration, but this value is within an acceptable range.
Choice D rationale:
Calcium 9 mg/dL The normal range for serum calcium levels can vary, but generally, a range of 8.5 to 10.5 mg/dL is considered normal. The provided value of 9 mg/dL falls within this range and is not significantly abnormal. Abnormal calcium levels can be indicative of various conditions, including thyroid disorders or kidney problems, but this value is not concerning.

Correct Answer is A
Explanation
Choice A rationale:
After a tonic-clonic seizure, it's common for the person to inadvertently bite their tongue, cheeks, or lips during the convulsive movements. Checking the mouth for any signs of bleeding or injuries is essential to ensure the person's safety and provide appropriate care.
Choice B rationale:
Placing the child's head in a hyperextended position is not recommended after a seizure. In fact, it's important to keep the person's head and neck in a neutral position to prevent potential injury. Hyperextending the neck could lead to strain or other complications.
Choice C rationale:
Giving the child a drink of water immediately after a seizure is not necessary and might be unsafe. The child may still be disoriented or have difficulty swallowing immediately after the seizure. It's best to ensure the child's safety and monitor their condition before offering any fluids.
Choice D rationale:
Administering naloxone intramuscularly is not indicated for a tonic-clonic seizure. Naloxone is an opioid antagonist used to reverse the effects of opioid overdose. Seizures have a different underlying cause, and administering naloxone would not be effective or appropriate in this context.
Correct Answer is C
Explanation
Choice A rationale:
Placing a toddler in a side-lying position on the affected side after administering otic medication is not recommended. This position can cause the medication to leak out, reducing its effectiveness, and can also increase the risk of infection. It's important to keep the medication in the ear canal for an adequate amount of time to allow it to work properly.
Choice B rationale:
Allowing the medication to reach room temperature prior to administration is not a critical step for otic medications. While warming certain medications can reduce discomfort, this is not a specific requirement for ear drops. Ensuring the cleanliness of the ear, proper positioning, and correct administration technique are more important.
Choice C rationale:
The correct choice. Sitting the child in an upright position is the recommended approach for administering otic medication. This position helps ensure that the medication remains in the ear canal and is not immediately expelled. It also facilitates better penetration of the medication into the ear canal, increasing its effectiveness.
Choice D rationale:
Gently pulling a child's ear upward is a technique used for administering otic medications to straighten the ear canal and allow better access to the medication. However, this step alone is not sufficient. Proper positioning of the child is equally important to prevent the medication from leaking out.
