A nurse enters a client's room and sees smoke coming from the bathroom.
Which of the following actions should the nurse take first?

Close the doors to the room and to the bathroom.

Activate the fire alarm system.

Assist the client to a nearby common area.

Use a fire extinguisher at the source of the smoke.

Answer and Explanation

The Correct Answer is B

Choice A rationale

Closing the doors can help contain the smoke, but it is not the first action. The priority is to activate the fire alarm to alert the fire department and initiate the building's emergency procedures.

Choice B rationale

Activating the fire alarm system ensures that all occupants are alerted to the fire, and the fire department is notified. This is the first step in managing a fire emergency.

Choice C rationale

Assisting the client to a nearby common area is important for their safety, but it should be done after activating the fire alarm.

Choice D rationale

Using a fire extinguisher may be necessary if the fire is small and contained, but the first priority is to alert others and get professional help on the way.

Correct Answer is A

Explanation

Choice A rationale

Placing white tape on the edges of stairs helps improve visibility and prevent falls, especially for older adults with vision impairments. This simple modification enhances safety in the home by making the edges of steps more noticeable, reducing the risk of missteps or trips.

Choice B rationale

Area rugs on wooden floors can be a tripping hazard, especially for older adults. They may cause slips or falls if they are not securely anchored, leading to potential injuries. It's generally safer to avoid using loose area rugs in high-traffic areas of the home.

Choice C rationale

Furnaces should be inspected annually, not every 2 years. Regular inspections ensure the furnace operates safely and efficiently, reducing the risk of carbon monoxide leaks or other hazards. An annual inspection is a key component of maintaining a safe home environment.

Choice D rationale

Running wires and cords under carpeting can create a fire hazard and increase the risk of electrical shock. This practice can damage the cords and cause overheating. It's safer to use cord protectors or secure cords along baseboards to prevent accidents.

A. Adverse effects occur more often and are more severe when you take only one antituberculosis medication. B. Taking several antituberculosis medications will protect your liver from toxic effects. C. The organism that causes TB becomes resistant to antituberculosis medications when you only take one medication. D. People who have a severe form of TB need several antituberculosis medications, but those who have less severe TB need just one medication.

Correct Answer is C

Explanation

Choice A rationale

Adverse effects of antituberculosis medications do occur, but taking a single medication doesn't necessarily reduce their frequency or severity. Combination therapy aims to prevent resistance, not specifically to avoid side effects.

Choice B rationale

Multiple medications in TB treatment don't directly protect the liver from toxic effects. In fact, they may increase the risk of hepatotoxicity, but the benefit outweighs the risk due to reduced resistance.

Choice C rationale

The primary reason for using multiple antituberculosis medications is to prevent the development of drug resistance. TB bacteria can quickly become resistant when only one medication is used, leading to treatment failure.

Choice D rationale

TB treatment typically involves multiple drugs regardless of the severity of the disease to ensure effective eradication of the bacteria and prevent resistance.
