The recommended dosage of amoxicillin is 20 to 40 mg/kg/day divided in equal doses q h. The medication is supplied as 50 mg/mL oral suspension.

The child weighs 72.6 lb. Calculate the single-dose range for this child.

Choice A rationale

Oxygen supports combustion, and smoking introduces a significant ignition source. Prohibiting smoking within the residence when oxygen is in use minimizes the risk of fire or explosion. The high concentration of oxygen creates an environment where even small sparks can rapidly escalate into a dangerous conflagration.

Choice B rationale

Frayed or damaged electrical cords can create sparks or generate heat, both of which are ignition sources in an oxygen-enriched environment. Ensuring electrical cords are in good working order prevents electrical shorts and reduces the risk of fire, safeguarding the client and the home from oxygen-related hazards.

Choice C rationale

Flammable liquids, such as gasoline, paints, or cleaning solvents, have low flash points and can easily ignite in the presence of an oxygen concentrator or oxygen cylinder. Storing them in a separate, well-ventilated area like a garage, away from the oxygen source, significantly reduces the risk of accidental combustion.

Choice D rationale

While fluorescent light bulbs generate less heat than incandescent bulbs, the primary concern with oxygen safety is open flames, sparks, and heat-generating appliances, not typical household lighting. This choice is less critical for oxygen safety than other factors, as fluorescent bulbs themselves do not pose a direct combustion risk.

Choice E rationale

While pets can be a tripping hazard or affect air quality, they generally do not pose a direct safety risk concerning oxygen use itself. The presence of pets in the home does not inherently increase the flammability risk associated with oxygen therapy, unlike combustible materials or ignition sources.

Choice F rationale

Alcohol-based hand sanitizers are flammable due to their alcohol content. In an oxygen-enriched environment, even small amounts of vaporized alcohol can ignite. Avoiding their presence or using non-alcohol-based alternatives minimizes the risk of accidental fire when oxygen is being used in the vicinity.

Choice A rationale

While support groups can be beneficial, this response is premature and dismisses the client's immediate emotional expression. It focuses on a generalized solution rather than exploring the client's individual feelings and the specific reasons for their social withdrawal. Understanding the underlying psychological impact of chronic illness is crucial for providing person-centered care.

Choice B rationale

Prescribing medication is outside the nurse's scope of practice. Furthermore, immediately suggesting an antianxiety agent without a comprehensive assessment of the client's mental and emotional state can mask the true source of their distress and prevent exploration of coping mechanisms or other interventions.

Choice C rationale

This therapeutic communication technique prioritizes active listening and allows the client to elaborate on their feelings and experiences. It demonstrates empathy and respect, fostering a trusting relationship. Understanding the client's perspective is fundamental to developing an individualized and effective care plan for managing the psychosocial challenges of COPD.

Choice D rationale

While friends can offer support, this statement generalizes and might not be relevant to the client's specific situation. It also shifts the focus away from the client's internal experience and onto external factors, potentially minimizing their current distress and the impact of their condition on social engagement.
