A small, round raised area appears under the client's skin as the nurse administers an intradermal medication. Which action should the nurse take?

Choice A reason: Orienting the client to their surroundings is essential for a confused patient. It can help reduce anxiety and prevent further confusion. It is a non-invasive, immediate intervention that can provide comfort and safety to the patient.

Choice B reason: Closing the client's room door is not recommended as it may increase the patient's feeling of isolation and can be a safety issue if the patient needs immediate assistance.

Choice C reason: Escorting the client back to the room is a correct action. It ensures the safety of the client by preventing falls or wandering, which could lead to harm.

Choice D reason: Raising all four side rails on the bed can be considered a form of restraint and is not recommended. It can increase the risk of injury if the client attempts to climb over the rails and can contribute to feelings of confusion and agitation.

Choice E reason: Securing a bed alarm on the mattress is a correct action. It alerts the staff if the client attempts to leave the bed, allowing for quick intervention to ensure the client's safety.

This respiratory care scenario requires applying knowledge of oxygen delivery systems and normal physiological responses. To answer correctly, the nurse must understand the mechanical function of a partial rebreather mask and recognize the significance of a normal adult respiratory rate during therapy.

Choice A rationale: Increasing the oxygen liter flow is unnecessary because the reservoir bag is already functioning correctly by not deflating completely. Liter flow for this mask must be high enough (typically 6 to 11 L/min) to keep the bag two-thirds full.

Choice B rationale: Encouraging deep breaths is not indicated as the client's respiratory rate of 14 breaths/minute is within the normal adult range of 12 to 20 breaths/minute. The current breathing pattern is effectively facilitating oxygenation without the need for coaching.

Choice C rationale: Removing the mask would interrupt oxygen therapy and is contraindicated. The reservoir bag is supposed to remain partially inflated during inhalation to ensure the client receives the prescribed oxygen concentration rather than room air or exhaled carbon dioxide.

Choice D rationale: The reservoir bag of a partial rebreather mask should not deflate completely during inspiration to prevent carbon dioxide buildup. Since the bag is functioning normally and the respiratory rate is stable, the nurse should simply document these findings.
