A nurse is caring for a client admitted with a rash. They are trying to rule out (r/o) varicella. Before entering the room, the nurse should be instructed to wear what kind of mask?

Choice A Reason:

Securing the oxygen tubing to the bed sheet near the client’s head is not recommended because it can lead to accidental dislodgement of the tubing, which can interrupt the oxygen supply. Additionally, this practice does not address the potential for nasal dryness and irritation that can occur with oxygen therapy. Properly securing the tubing should involve ensuring it is comfortably positioned and not at risk of being pulled or dislodged.

Choice B Reason:

Attaching a humidifier bottle to the base of the flow meter is the correct action because it helps to add moisture to the oxygen being delivered to the client. Oxygen therapy, especially at higher flow rates like 5 L/min, can dry out the nasal passages and mucous membranes, leading to discomfort and potential complications. The humidifier bottle ensures that the oxygen is humidified, which helps to prevent dryness and irritation, making the therapy more comfortable and effective for the client.

Choice C Reason:

Applying petroleum jelly to the nares is not recommended because petroleum-based products can be flammable and pose a risk when used in conjunction with oxygen therapy. Additionally, petroleum jelly can trap bacteria and potentially lead to infections. Instead, water-based lubricants or saline nasal sprays are safer alternatives for soothing dry nasal passages.

Choice D Reason:

Removing the nasal cannula while the client eats is not advisable because it interrupts the continuous delivery of oxygen, which is essential for clients with pneumonia who may already have compromised respiratory function. Instead, the nurse should ensure that the nasal cannula is securely in place and that the client is receiving the prescribed oxygen therapy at all times, including during meals.

Choice A Reason:

“N95 (personal respirator mask)” is correct because varicella (chickenpox) is an airborne disease. The N95 mask is designed to filter out at least 95% of airborne particles, making it essential for protecting healthcare workers from inhaling infectious agents.

Choice B Reason:

“Surgical mask” is incorrect because while surgical masks provide a barrier against large respiratory droplets, they do not offer sufficient protection against airborne particles. Varicella can be transmitted through tiny airborne droplets, which necessitates the use of an N95 mask.

Choice C Reason:

“They don’t need a mask” is incorrect because healthcare workers must wear appropriate personal protective equipment (PPE) to prevent the spread of infectious diseases. Not wearing a mask would put the nurse at risk of contracting varicella.

Choice D Reason:

“Only the client needs a mask” is incorrect because while it is important for the client to wear a mask to reduce the spread of infectious droplets, the nurse also needs to wear an N95 mask to protect themselves from airborne transmission.
