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 C
Explanation
The correct answer ischoice C.
Choice A rationale:
A lead level of 10 mcg/dL is above the CDC’s reference value of 3.5 mcg/dL and would require more immediate follow-up and intervention, not just rescreening in one year.
Choice B rationale:
A lead level of 18 mcg/dL is significantly elevated and would necessitate immediate medical intervention and frequent monitoring, rather than waiting a year for rescreening.
Choice C rationale:
A lead level of 4 mcg/dL is slightly above the CDC’s reference value of 3.5 mcg/dL.While it is concerning, it may be appropriate to rescreen in one year if no other risk factors are present.
Choice D rationale:
A lead level of 44 mcg/dL is dangerously high and requires urgent medical treatment and frequent follow-up, not just rescreening in one year.
Correct Answer is C
Explanation
A bulging fontanel is a manifestation associated with a CNS infection in an 11- month-old infant.
A bulging fontanel can be a sign of increased intracranial pressure, which can
occur with meningitis or encephalitis, both of which are types of CNS infections.
Choice A is incorrect because oliguria, or decreased urine output, is not typically associated with a CNS infection.
Choice B is incorrect because jaundice, or yellowing of the skin and eyes, is not typically associated with a CNS infection.
Choice D is incorrect because a negative Brudzinski sign would indicate that there is no neck stiffness, which would be an unlikely finding in a CNS infection.
