A transferable safety strategy is to regularly inspect and maintain all assistive devices in nursing care to ensure reliability and safety.

This question tests the safe use of equipment and assistive devices. The priority safety concern is the use of petroleum-based products with oxygen, which poses a fire hazard due to flammability. Instructing the client to stop using petroleum-based products and switch to water-based lubricant is the safest action because it eliminates the ignition risk immediately. Assessing saturation (B), increasing flow (C), or requesting a different device (D) do not address the flammability issue and are less optimal. The decision-making principle for oxygen therapy is to avoid oil-based substances near delivery devices. Safety guidelines prohibit petroleum products to prevent combustion in oxygen-rich environments. A transferable safety strategy is to educate clients on compatible materials with any medical gas equipment to avoid fire hazards.

This question tests the safe use of equipment and assistive devices. The priority safety concern is adjusting oxygen flow without prescription, which can lead to oxygen toxicity or inadequate therapy. The nurse should question turning the oxygen flow rate up without a prescription change because it deviates from the ordered therapy and poses health risks. Continuous use (A), keeping extra cannulas (C), and placing the concentrator openly (D) are correct practices and do not warrant questioning. The decision-making principle for oxygen equipment is to adhere strictly to prescribed flow rates. Safety guidelines prohibit self-adjustment to ensure therapeutic efficacy and prevent complications. A transferable safety strategy is to reinforce adherence to prescriptions with any medical device to maintain safety and effectiveness in nursing care.

This question tests safe use of equipment and assistive devices, specifically reacher safety for a client with vision impairment and arthritis. The priority safety concern is the missing rubber gripping pads exposing metal ends, which could cause injury to the client or damage to items being grasped. Removing the reacher from use and replacing it with a functioning device (A) is the correct answer because it immediately eliminates the safety hazard of exposed metal that could cut or injure the client. Teaching slower use (B) doesn't address the equipment defect, assessing grip strength (C) is irrelevant to the damaged equipment, and requesting therapy evaluation (D) delays addressing the immediate hazard. The fundamental principle is that assistive devices must be intact and functioning properly before use - damaged equipment poses greater risk than benefit. Exposed metal on a reacher is particularly dangerous for clients with impaired vision who rely on touch. This safety principle applies to all assistive devices - inspect for damage, wear, or missing parts before each use, and remove defective equipment from service immediately.

This question tests the safe use of equipment and assistive devices. The priority safety concern is the cracked magnifier lens, which poses a risk of cuts or ineffective use for a client with cataracts. The magnifier lens being cracked and potentially cutting the hand indicates a hazard because it compromises safety and functionality. Placement on a table (A), storage in a drawer (B), and use while seated (D) are appropriate and do not indicate hazards. The decision-making principle for vision aids is to ensure they are intact and safe. Safety guidelines require replacement of damaged devices to prevent injury. A transferable safety strategy is to inspect assistive devices for integrity before client use in any care scenario.

This question tests the safe use of equipment and assistive devices. The priority safety concern is preventing fire hazards associated with oxygen use in the home. Keeping oxygen at least 5 feet away from open flames and heat sources is the safest precaution because oxygen accelerates combustion. Changing the cannula (B), using a humidifier (C), and wearing prongs downward (D) are important but secondary to fire prevention. The decision-making principle for oxygen teaching is to prioritize fire safety instructions. Safety guidelines mandate distance from ignition sources as the top priority. A transferable safety strategy is to emphasize hazard avoidance in education for any home medical equipment.

This question tests safe use of equipment and assistive devices, specifically identifying oxygen safety hazards in home care. The priority safety concern is the use of petroleum jelly on the nares while using oxygen, which is a fire hazard because petroleum-based products are flammable in oxygen-enriched environments. The client applying petroleum jelly to the nares (B) is the correct answer as this indicates a safety hazard - only water-based lubricants should be used with oxygen therapy. Storing cylinders upright (A) is proper safety practice, routing tubing along walls (C) reduces trip hazards, and posting no-smoking signs (D) promotes safety awareness. The key principle is that all products used near oxygen delivery devices must be water-based, as petroleum-based products can ignite in oxygen-enriched environments. Even small amounts of petroleum jelly near the oxygen source create significant fire risk. This safety principle extends to all substances near oxygen - avoid oil-based products, aerosols, and flammable materials while using only water-based alternatives for skin care and equipment maintenance.

This question tests safe use of equipment and assistive devices, specifically proper walker height adjustment for a client with Parkinson disease. The priority safety concern is the walker being set too high, forcing the client's elbows into full extension, which compromises stability and control. The walker handgrips set too high causing elbow extension (C) is the correct answer as this indicates improper walker height that reduces the client's ability to bear weight effectively and maintain balance. Proper wrist alignment (A) and slight elbow flexion (B) indicate correct height adjustment, while placing the walker in front (D) is appropriate technique. The fundamental principle is that walker height must allow 15-30 degrees of elbow flexion when gripping the handles to optimize biomechanics and control. Full elbow extension reduces shock absorption, decreases pushing power, and compromises balance - particularly dangerous for clients with Parkinson's who already have postural instability. This height adjustment principle applies to all ambulatory aids - proper fit ensures optimal biomechanics, reducing fatigue and fall risk while maximizing stability and control.

This question tests safe use of equipment and assistive devices, specifically oxygen safety in the home setting. The priority safety concern is the fire hazard created by having an oxygen concentrator and space heater plugged into the same power strip, which can cause overheating, electrical overload, and fire near an oxygen-enriched environment. Instructing the client to move the space heater away and plug the oxygen concentrator directly into a wall outlet (A) is the correct answer as it immediately eliminates the fire hazard. Assessing oxygen saturation (B) doesn't address the safety issue, requesting discontinuation of oxygen (C) compromises the client's respiratory status, and teaching about flow rate adjustment (D) is unrelated to the safety concern. The fundamental principle is that oxygen equipment must be kept away from heat sources and electrical hazards, with concentrators plugged directly into wall outlets to prevent overload. Oxygen accelerates combustion, making any heat or spark source extremely dangerous. This safety principle applies to all oxygen delivery systems - maintain safe distances from heat, flames, and electrical sources while ensuring proper ventilation and electrical safety.

This question tests the safe use of equipment and assistive devices. The priority safety concern is the extension cord creating a tripping hazard across a walkway in a home with oxygen use. Using an extension cord across a walkway to power the concentrator indicates a hazard because it risks falls or damage to equipment. Keeping the concentrator from the wall (A), storing tubing (C), and posting signs (D) are safe practices and do not indicate hazards. The decision-making principle for home oxygen is to route cords safely to avoid trips. Safety guidelines require clear pathways around medical equipment. A transferable safety strategy is to manage cords and tubing to prevent entanglement in any home care equipment setup.
