A nurse is assessing a preschooler who has a calcium level of 8.0 mg/dL.
Which of the following findings should the nurse expect?
Negative Chvostek's sign.
Muscle tremors.
Dry, sticky mucous membranes.
Polyuria.
The Correct Answer is B
A calcium level of 8.0 mg/dL is below the normal range for adults, which is 8.8 to 10.4 mg/dL.
This condition is known as hypocalcemia and can cause muscle spasms and aches.
Choice A is incorrect because a positive Chvostek’s sign, not a negative one, is a clinical sign of hypocalcemia.
Choice C is incorrect because dry, sticky mucous membranes are not a symptom of hypocalcemia.
Choice D is incorrect because polyuria (frequent urination) is a symptom of hypercalcemia (high calcium levels), not hypocalcemia.

Correct Answer is A
Explanation
The correct answer is choice a. Reposition the child every 2 hr.
Choice A rationale:
Repositioning the child every 2 hours is essential to prevent complications such as pressure ulcers and to promote comfort and circulation.
Choice B rationale:
Removing the traction boot during baths is not recommended as it can disrupt the traction setup and potentially worsen the condition.
Choice C rationale:
Reducing fluid intake is not necessary for managing Legg-Calve-Perthes disease and could lead to dehydration.
Choice D rationale:
Applying antibiotic ointment to pin sites daily is not applicable in this scenario as Buck extension traction typically does not involve pin sites.
Correct Answer is B
Explanation
Acute lead poisoning in toddlers can cause anorexia, as well as vomiting, abdominal pain, and constipation.
These symptoms can progress to seizures, coma, and even death if not treated promptly.
Choice A, increased urinary output, is not the correct answer because lead poisoning can cause a decrease in urinary output due to the effect of lead on the kidneys.
Choice C, diarrhea, is not the correct answer because lead poisoning is more likely to cause constipation than diarrhea.
Choice D, jaundice, is not the correct answer because jaundice is not a common finding in lead poisoning.
Jaundice is a yellowing of the skin and whites of the eyes caused by an excess of bilirubin in the blood, which is not directly related to lead poisoning.
