A nurse in an assisted-living facility is reinforcing teaching with staff members about preparing for an external chemical disaster. Which of the following instructions should the nurse include?

Explanation:

A nasal cannula is a device used to deliver supplemental oxygen to a client. It consists of two prongs that are inserted into the client's nostrils and connected to an oxygen source. The nasal cannula is commonly used for low-flow oxygen delivery at a rate of 1 to 2 liters per minute (L/min).

The other options mentioned are not necessary supplies for the client upon discharge:

B- Petroleum jelly is not directly related to oxygen therapy and is not a required supply for the client. It is a common topical ointment used for various purposes such as moisturizing the skin or protecting the lips, but it is not specifically needed for oxygen administration.

C- An oxygen mask is an alternative device for oxygen delivery but is not typically used at a flow rate of 1 to 2 L/min. Oxygen masks are usually employed for higher flow rates or in specific clinical situations that require a different oxygen delivery method.

D- A reservoir bag is a component of some oxygen delivery systems, such as a non-rebreather mask or a bag-valve-mask device. However, at a flow rate of 1 to 2 L/min, a reservoir bag is not typically used. It is more commonly utilized in situations where higher oxygen concentrations or higher flow rates are required.

Choice A: While nitroglycerin is a common medication for angina, calling the provider after just one dose is not the recommended action. Nitroglycerin helps relax coronary arteries and improve blood supply to the heart. However, if chest pain persists, the client should follow additional steps..

Choice B: This describes the Valsalva maneuver, which involves holding the breath and bearing down as though straining to initiate a bowel movement. While this technique can regulate heart rhythms and help the ears to pop, it is not the recommended response to chest pain from angina.

Choice C: Correct: This statement demonstrates an understanding of appropriate action. When experiencing angina, the client should stop any physical activity, sit down, or lie down. Resting helps reduce the heart’s workload and allows blood flow to stabilize.

Choice D: Aspirin can be beneficial during angina episodes. However, the recommended dose is usually 162 to 325 milligrams (one tablet). Taking two tablets at once may not be necessary unless specifically advised by a healthcare provider.
