A nurse is collecting data from a client who reports feeling stress. Which of the following should the nurse identify as an external stressor?

A) "Ensure that the negative air pressure is active for the client’s room.": Negative air pressure is used for airborne precautions, such as in the case of tuberculosis or other airborne infections. MRSA is primarily spread through direct contact, not airborne transmission, so negative air pressure is not necessary in this situation.

B) "Place the client in a room with a high-efficiency particulate air (HEPA) filter.": A HEPA filter is used for airborne precautions to filter out airborne particles like those found in diseases such as tuberculosis or measles. Since MRSA is transmitted through direct contact and not airborne particles, placing the client in a room with a HEPA filter is not necessary.

C) "Have the client wear a mask when they are out of their room.": MRSA is typically spread by direct contact with infected wounds, bodily fluids, or contaminated surfaces. It is not transmitted via respiratory droplets, so there is no need for the client to wear a mask when they leave their room. The focus should be on contact precautions rather than respiratory precautions.

D) "Don gloves prior to assisting the client with brushing their teeth.": MRSA is a contact-borne infection, so it is essential to use proper personal protective equipment, such as gloves, when coming into direct contact with the client or any of their bodily fluids or contaminated items (such as toothbrushes). Donning gloves prior to assisting with brushing their teeth ensures that the nurse avoids direct contact with potential sources of infection. This is an important measure in preventing the spread of MRSA.

A) Check the client's pulse rate: While it is important to assess vital signs, the priority in this scenario is ensuring that the client’s airway is open and that they can breathe adequately. A pulse rate check can be performed after addressing the immediate respiratory needs.

B) Administer oxygen to the client: Administering oxygen is important for clients who are cyanotic and showing signs of respiratory distress. However, oxygen will not be effective if the airway is obstructed. The first priority is to ensure that the airway is open and clear, as this is the most immediate need for breathing.

C) Establish a patent airway for the client: The most immediate priority is to ensure that the client has a patent airway. Cyanosis and a decreased respiratory rate with shallow respirations indicate that the client is likely unable to get enough oxygen, possibly due to an obstruction or inadequate airway. Once the airway is secured, other interventions such as administering oxygen can follow.

D) Place a pulse oximeter on the client's finger: While measuring oxygen saturation is important, the priority action is to ensure that the client’s airway is open first. If the client is cyanotic and showing signs of respiratory distress, the nurse must address the airway immediately before assessing the pulse oximeter reading, as it may not provide accurate data without a patent airway.
