A nurse is planning teaching for a client and their family about home oxygen therapy. Which of the following information should the nurse plan to include in the teaching?

The correct answer is choice D. Avoid using nail polish remover around the client. Nail polish remover contains acetone, which is a flammable substance that can ignite in the presence of oxygen.

Using nail polish remover around the client can increase the risk of fire and burn injuries.

Choice A is wrong because synthetic fabrics can generate static electricity, which can also cause sparks and ignite oxygen.

The client’s bedding should be made of cotton or wool, which are natural fabrics that do not produce static electricity.

Choice B is wrong because petroleum jelly is a petroleum-based product that can react with oxygen and cause skin irritation or burns.

The client should use water-based moisturizers to soothe the mucous membranes.

Choice C is wrong because alcohol-based cleaning products are also flammable and can cause fires or explosions when exposed to oxygen.

The client should use mild soap and water to clean the equipment, and follow the manufacturer’s instructions for maintenance.

Some general safety tips for home oxygen therapy are:

• Keep away from heat and flame, such as candles, matches, lighters, stoves, fireplaces, etc.
• Do not smoke or allow others to smoke near the oxygen source
• Do not use aerosols, vapor rubs, oils, or other products that contain flammable substances near the oxygen source
• Store oxygen tanks or cylinders in a well-ventilated area away from direct sunlight and heat sources
• Secure oxygen tanks or cylinders to prevent them from falling or rolling
• Use the exact rate of oxygen prescribed by the doctor for each activity
• Check the oxygen gauge or level regularly and call the medical supply company when it is low
• Use a humidifier bottle if prescribed by the doctor to prevent dryness of the mucous membranes
• Change the nasal cannula, mask, and tubing as instructed by the medical supply company to prevent

The nurse should first administer oxygen at 2 L/min via nasal cannula because the client has signs of hypoxemia (low oxygen saturation) and respiratory distress (increased respiratory rate) that may worsen the chest pain and myocardial ischemia. Oxygen therapy can help improve oxygen delivery to the heart muscle and reduce the workload of the heart.
The nurse should then administer sublingual nitroglycerin as prescribed because nitroglycerin is a vasodilator that can help relieve chest pain by dilating the coronary arteries and improving blood flow to the heart. Nitroglycerin can also lower blood pressure and reduce cardiac preload and afterload, which can decrease myocardial oxygen demand.
Other choices:

• Prepare the client for cardiac catheterization: This may be a later intervention if the chest pain persists or if the client has a confirmed myocardial infarction, but it is not the first priority for the nurse. Cardiac catheterization is an invasive procedure that involves inserting a catheter into a large artery and advancing it to the coronary arteries to visualize any blockages or stenosis. The procedure may also involve angioplasty or stent placement to restore blood flow to the affected area.

• Request a prescription for an increase in statin: This may be a long-term intervention to lower the client’s LDL cholesterol and prevent further plaque formation in the coronary arteries, but it is not an immediate intervention for chest pain. Statins are lipid-lowering drugs that can reduce the risk of cardiovascular events in clients with CAD, but they do not have a direct effect on chest pain or myocardial ischemia.

• Check a STAT cardiac troponin: This may be a diagnostic test to confirm or rule out a myocardial infarction, but it is not an intervention for chest pain. Cardiac troponin is a protein that is released into the bloodstream when there is damage to the heart muscle. Elevated levels of cardiac troponin indicate a myocardial infarction or other cardiac injury.

• Request a prescription for a beta-blocker: This may be an adjunctive therapy to reduce chest pain and prevent complications, but it is not the first-line intervention for chest pain. Beta-blockers are drugs that block the effects of adrenaline on the heart and blood vessels, which can lower heart rate, blood pressure, and myocardial oxygen demand. Beta-blockers can also prevent arrhythmias and reduce mortality in clients with CAD.
