A nurse is caring for a client who has a prescription for chlorpromazine. Which of the following findings should the nurse identify as an indication that the medication is effective?

Administer high-dose antibiotic therapy.

Rationale:

• A. Initiate droplet isolation precautions is incorrect because cystic fibrosis is not transmitted by droplets, but by autosomal recessive inheritance.
• B. Keep the child on NPO status for 12 hr is incorrect because there is no indication for withholding oral intake in this child. The child needs adequate hydration and nutrition to prevent dehydration and malnutrition due to increased metabolic demands and mucus production.
• C. Maintain the child on bed rest for 24 hr is incorrect because bed rest can worsen the child's respiratory status by decreasing lung expansion and increasing mucus retention. The child needs to be encouraged to ambulate and participate in activities as tolerated to promote airway clearance and prevent atelectasis and infection.
• D. Administer high-dose antibiotic therapy is correct because the child has signs of a pulmonary infection, such as wheezing, productive cough, and thick sputum. Antibiotics are indicated to treat the infection and prevent complications such as pneumonia and bronchiectasis.

Use a reward system to modify the child's behavior.

Rationale:

• A. Incorrect. Maintaining a flexible daily schedule for the child may increase their anxiety and confusion, as they may have difficulty adapting to changes in routine and expectations. The nurse should advise the parents to establish a consistent and structured schedule for the child, with clear rules and boundaries.
• B. Correct. Using a reward system to modify the child's behavior is an effective strategy to reinforce positive behaviors and reduce negative ones. The nurse should help the parents identify specific and measurable goals for the child, and provide them with praise, tokens, or privileges when they achieve them.
• C. Incorrect. Providing a variety of family members to care for the child may overwhelm them and impair their social skills development, as they may have difficulty forming attachments and communicating with different people. The nurse should encourage the parents to select one or two primary caregivers for the child, who can provide them with consistent and supportive interactions.
• D. Incorrect. Administering alprazolam as needed to reduce the child's anxiety is not recommended, as it may cause adverse effects such as sedation, dependence, or withdrawal symptoms. The nurse should educate the parents about nonpharmacological interventions for anxiety, such as relaxation techniques, cognitive behavioral therapy, or social skills training.
