A nurse is caring for a school-age child who has lice. The child's guardian prefers the use of a natural remedy to treat the lice. Which of the following treatments should the nurse recommend?

Use a dandruff shampoo followed by drying the child's hair on high heat.

Apply mayonnaise to the child's head.

Boil the child's combs, brushes, and hair accessories in water for 10 min.

Manually remove the lice eggs with a special comb.

Answer and Explanation

The Correct Answer is B

Rationale:

A. Dandruff shampoo does not kill lice or nits effectively. High heat from a hair dryer is not a reliable or recommended method for lice eradication and may cause burns or scalp irritation.

B. This is a natural remedy sometimes used to suffocate lice. It is applied generously to the hair and scalp, covered with a shower cap for several hours, and then washed out. While not as consistently effective as pediculicides, it aligns with the guardian’s preference for nonchemical, natural treatment.

C. While cleaning personal items is important to prevent reinfestation, this action alone does not treat the lice on the child’s scalp. It is a supportive measure rather than a primary treatment.

D. Combing with a fine-tooth (nit) comb is an effective adjunctive method, especially after treatment, but it is time-consuming and typically used in combination with another treatment. It may not be sufficient alone to eliminate lice entirely.

Correct Answer is A

Explanation

Rationale:

A. Regular moderate physical activity is recommended for clients with heart failure, as tolerated, to improve cardiovascular fitness, reduce symptoms, and enhance quality of life. Walking several times per week is a safe and effective exercise that promotes circulation, prevents deconditioning, and supports overall heart health. Activity plans should be individualized based on the client’s functional status and provider recommendations.

B. Clients with heart failure are usually advised to limit saturated fat and cholesterol intake to reduce cardiovascular strain. Whole milk is high in saturated fat; low-fat or fat-free dairy products are preferred. Including whole milk with every meal is not recommended.

C. For heart failure management, clients are instructed to monitor daily weight at the same time each morning. Daily weight monitoring helps detect fluid retention early, allowing prompt intervention and preventing exacerbations. Weighing every other day could delay detection of fluid buildup.

D. Fluid intake for heart failure clients is often restricted, especially for those with significant fluid retention, edema, or hyponatremia. Typical recommendations range from 1.5 to 2 L/day, individualized by the healthcare provider. Encouraging unrestricted fluid intake could worsen heart failure symptoms.

A. "We use a space heater in my child's bedroom during the winter months." B. "I like to make stained-glass window hangings in my free time." C. "I often purchase older toys from yard sales for my child to play with." D. "Our basement has a concrete floor and rock walls." E. "We are finally getting our older home remodeled."

Correct Answer is ["B","C","E"]

Explanation

Rationale:

A. Space heaters do not contribute to lead exposure. Unless the heater is old and coated with lead paint (rare), this is not a recognized risk factor. Lead poisoning is primarily linked to ingestion or inhalation of lead dust, not heat sources.

B. Many stained-glass materials, especially solder, contain lead. Children may be exposed to lead dust if they touch the materials or if lead dust settles on surfaces that the child contacts. This represents a household hobby-related exposure risk.

C. Toys manufactured before 1978 may contain lead-based paint. Children can ingest lead by biting, mouthing, or licking toys. Secondhand toys are a well-documented source of lead exposure in homes.

D. Concrete and rock do not naturally contain lead. Unless the walls were painted with lead-based paint or contaminated with lead dust from previous construction, this is not a direct risk.

E. Renovation of homes built before 1978 can release lead dust from old paint, plaster, or pipes. Children are at high risk of exposure during remodeling because dust can settle on floors, furniture, and toys. Remodeling activities are a major source of preventable lead exposure.
