A nurse is admitting a school-age child who has bacterial meningitis.
Which of the following types of isolation precautions should the nurse initiate?

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.

a. Improves muscle strength.

Explanation:

Neostigmine is a medication used in the treatment of myasthenia gravis (MG). It belongs to a class of drugs called cholinesterase inhibitors. Neostigmine works by inhibiting the breakdown of acetylcholine, a neurotransmiter involved in muscle contraction. In MG, there is a decrease in the amount of acetylcholine available at the neuromuscular junction, leading to muscle weakness and fatigue.

By inhibiting the breakdown of acetylcholine, neostigmine helps to increase the concentration of acetylcholine at the neuromuscular junction. This, in turn, improves muscle strength and can alleviate the symptoms of weakness and fatigue associated with MG.

Option b, destroying the antibodies that cause MG, is not accurate. Myasthenia gravis is an autoimmune disorder characterized by the presence of antibodies that interfere with neuromuscular transmission.

Neostigmine does not directly target or eliminate these antibodies.

Option c, enhancing immune system function, is not accurate either. Neostigmine primarily acts on the neuromuscular junction to improve muscle strength and does not have a direct effect on immune system function.

Option d, preventing excessive coughing, is not the primary action of neostigmine. While increased muscle strength may indirectly improve respiratory function and reduce coughing in individuals with myasthenia gravis, it is not the primary indication or action of neostigmine.

Therefore, the most accurate information to include in teaching about neostigmine for a client with myasthenia gravis is that it improves muscle strength.
