A nurse is assisting with the admission of an infant who has experienced vomiting and loose, watery stools for the past 3 days. Which of the following findings indicates that the child is experiencing moderate dehydration?

• request a prescription for an increase in statin medication: Although the client's total cholesterol is elevated at 230 mg/dL, adjusting lipid management is not the immediate priority during an acute chest pain episode. The immediate focus should be stabilizing airway, breathing, and circulation.
• prepare the client for cardiac catheterization: Cardiac catheterization may ultimately be needed to assess coronary artery blockages, but before this, the client must be stabilized with oxygen and medications to control chest pain and improve oxygenation.
• administer oxygen at 2 L/min via nasal cannula: The client’s oxygen saturation dropped to 92% on room air, which is low for someone experiencing chest pain and possible myocardial ischemia. Administering supplemental oxygen improves myocardial oxygen supply and reduces cardiac workload, addressing airway and breathing priorities.
• check a STAT cardiac troponin: The client’s initial troponin level was normal, but troponin can take several hours to rise after myocardial injury. While monitoring serial troponins is important, managing oxygenation and chest pain relief takes precedence right now.
• administer sublingual nitroglycerin: After ensuring oxygenation, sublingual nitroglycerin should be administered to relieve chest pain by dilating coronary arteries and decreasing myocardial oxygen demand. It helps reduce ischemia and may prevent further cardiac injury.
• request a prescription for a beta-blocker: Beta-blockers help control heart rate and blood pressure but are not the immediate first-line response for active chest pain and oxygen desaturation. Oxygen and nitroglycerin must be prioritized first to address the acute ischemic event.

A. Smoking in bed: Smoking in bed is a major fire hazard and one of the leading causes of residential fires. Falling asleep with a lit cigarette can easily ignite bedding, mattresses, or upholstered furniture, leading to fast-spreading, deadly fires. This behavior significantly increases the risk of injury or death from residential fires.

B. Leaving the stove on: Leaving the stove unattended can also cause kitchen fires, but cooking-related incidents typically lead to localized fires rather than being the top cause of overall residential fires. Proper supervision while cooking is important, but smoking in bed remains a more dangerous, widespread cause of fatal home fires.

C. Lack of smoke detectors: Lack of smoke detectors does not cause fires but delays detection, increasing the risk of injury or death once a fire has already started. While smoke detectors are crucial for early warning and safety, they are not an ignition source that directly leads to the start of residential fires.

D. Placing a space heater 5ft from bed: Placing a space heater 5 feet away from a bed is generally considered safe, as heaters need clearance but are unlikely to cause fires at that distance. Improper use of space heaters can be hazardous, but when correctly placed, they are not the primary cause of residential fires compared to smoking in bed.
