Insulin should never be frozen, as freezing damages the protein structure, making the medication ineffective and unsafe to administer. If insulin accidentally freezes, it must be discarded. The correct practice is to store unopened vials in the refrigerator, not the freezer, until ready for use.

There is no requirement to return unopened insulin after 1 month on the unit. Unopened insulin vials are stable when refrigerated and can be stored until their manufacturer’s expiration date. Returning vials after only 1 month would lead to unnecessary waste and is not consistent with medication management guidelines.

Insulin is not discarded based on the number of doses withdrawn. Instead, discard recommendations are based on time after opening, generally 28 days for most insulins. The vial remains usable as long as it is within this timeframe, properly stored, and free of contamination or cloudiness (unless it is an insulin type that is normally cloudy).

Shakiness is typically a symptom of hypoglycemia, not hyperglycemia. It occurs when blood glucose levels drop too low, causing the body to release epinephrine, which leads to tremors, sweating, and irritability.

Pallor is more closely associated with hypoglycemia, decreased perfusion, or shock. It is not a characteristic sign of hyperglycemia.

While anxiety can occur in many conditions, it is most commonly linked with hypoglycemia, when the body mounts an adrenergic response due to rapidly falling glucose levels. Anxiety alone is not considered a primary indicator of hyperglycemia.

Although a referral to social services may be needed, this action does not come first. Before involving other departments, the nurse must gather adequate assessment data to support the suspicion of abuse.

Incorrect as the first action. Nurses are mandatory reporters, and reporting suspected abuse is required; however, the nurse must first collect accurate assessment data and a history to ensure the report is complete and factual. Reporting comes after the initial assessment.

Explaining legal or procedural steps to the child at this point can increase fear or confusion. The nurse should first focus on gathering information and ensuring the child's immediate safety before offering explanations or reassurance.

It is not necessary to throw away stuffed animals. Instead, items that cannot be washed can be sealed in an airtight plastic bag for 14 days, which suffocates any surviving lice. Discarding them is unnecessary and creates avoidable expense.

Home remedies such as mayonnaise, petroleum jelly, or oils are not evidence-based and do not reliably kill lice or nits. They are not recommended by pediatric or public health guidelines.

Head lice are human parasites and cannot survive on pets. Treating animals is unnecessary and has no effect on controlling or eliminating lice infestations.

Patchy hair loss can result from excessive scratching, secondary bacterial infection, or other scalp disorders (for example, tinea capitis or alopecia areata). While lice-related scratching can contribute to hair breakage or localized hair loss, hair loss alone is not diagnostic of pediculosis capitis and requires further inspection.

Intense pruritus is a common symptom of head lice because the host mounts an allergic response to louse saliva. However, itching is nonspecific, many scalp conditions (dandruff, eczema, fungal infections, dermatitis) cause itching, so it cannot definitively establish the diagnosis by itself.

These findings are characteristic of secondary bacterial infection of the skin, such as impetigo, not of an uncomplicated lice infestation. Although scratching from lice can lead to skin breakdown and secondary infection, crusted, purulent lesions indicate infection that needs separate treatment and are not the hallmark of pediculosis capitis.

Bubble baths, hot water, and frequent bathing can dry out the skin and exacerbate eczema (atopic dermatitis). Short, lukewarm baths with mild, fragrance-free cleansers are recommended instead.

Wool is a common irritant and can trigger eczema flare-ups. Children with eczema should wear soft, breathable fabrics, such as cotton, to prevent additional skin irritation.

Fabric softeners and scented laundry detergents can irritate sensitive skin and worsen eczema. Clothing should be washed with mild, fragrance-free detergents and rinsed thoroughly.

Atopic dermatitis (eczema) is not caused by bacteria, so antibiotics are generally not indicated unless there is a secondary bacterial infection. Routine antibiotic use is not part of standard eczema management.

Liquid nitrogen (cryotherapy) is used for wart removal or certain skin lesions, not for atopic dermatitis. Eczema management focuses on skin hydration, avoiding triggers, and controlling inflammation, not lesion removal with cryotherapy.

Warm compresses can irritate sensitive skin and worsen itching or inflammation. Cool, wet compresses are recommended for soothing acute flare-ups of atopic dermatitis.

This statement is appropriate. Children with type 1 diabetes should eat a carbohydrate-containing snack before physical activity to prevent hypoglycemia during exercise.

Rotating insulin injection sites within the same general area helps prevent lipodystrophy (thickened or atrophied skin) and ensures consistent insulin absorption.

This statement is appropriate. Regular blood glucose monitoring is essential for tight glycemic control and helps guide insulin dosing and dietary adjustments.
