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 D
Explanation
The correct answer is choice D: Pediculosis capitis.
Choice D rationale: Pediculosis capitis is an infestation of head lice, which causes symptoms such as white flakes that do not brush off the hair easily and a rash on the back of the neck. These symptoms are due to the lice feeding on the scalp and laying eggs (nits), which can cause itching and irritation.
Choice A rationale: Folliculitis is an inflammation of the hair follicles, typically caused by bacterial or fungal infections. While it can cause a rash, it is not characterized by white flakes in the hair.
Choice B rationale: Tinea capitis, also known as ringworm of the scalp, is a fungal infection that causes scaly, itchy patches on the scalp. It may lead to hair loss in the affected areas, but it does not typically cause white flakes that do not brush off the hair.
Choice C rationale: Impetigo contagiosa is a highly contagious bacterial skin infection that causes blisters or sores on the skin. It does not involve white flakes in the hair and primarily affects exposed skin rather than the scalp.
Correct Answer is B
Explanation
According to the CDC, one of the individual risk factors for suicide is a previous suicide attempt.
Choice A is not the answer because while substance abuse is a risk factor for suicide, it is not the priority risk factor for suicide completion in this case.
Choice C is not the answer because while loss of relationships can contribute to
suicide risk, it is not the priority risk factor for suicide completion in this case.
Choice D is not the answer because while a history of mental illness is a risk factor for suicide, it is not the priority risk factor for suicide completion in this case.
