A nurse is reinforcing teaching with a client who is to start taking montelukast to treat asthma. Which of the following statements by the client indicates an understanding of the teaching?

A. Add tap water as needed to the suction control chamber.

This is not the correct action. The suction control chamber of a water-seal chest tube drainage system is typically filled with sterile water to the prescribed level by the healthcare provider during the initial setup. Adding tap water to the suction control chamber can disrupt the balance of the system and affect the prescribed suction level. The nurse should not add tap water without specific instructions from the healthcare provider.

B. Maintain the drainage container below the level of the client's chest.

This is the correct action. In a water-seal chest tube drainage system, it's important to keep the drainage container below the level of the client's chest. This positioning allows gravity to assist in the drainage of air or fluid from the pleural space into the drainage container. It also helps prevent backflow of fluid or air into the chest cavity, ensuring the effectiveness of the drainage system.

C. Empty the collection container every shift.

While it may be necessary to empty the collection container if it becomes full, emptying it every shift is not a set rule. The frequency of emptying the collection container should be based on the volume of drainage and the facility's policy. The nurse should monitor the collection container regularly and empty it when it reaches the appropriate level, typically around half full or as indicated by facility protocol.

D. Clamp the chest tubes if it becomes disconnected.

Clamping the chest tubes if they become disconnected is not recommended. It can lead to tension pneumothorax, a life-threatening condition where air accumulates in the pleural space and compresses the lung. If a chest tube becomes disconnected, the nurse should immediately assess the situation, secure the chest tube connections, and notify the healthcare provider for further management.

A. Nausea

While nausea can occur in hypoxia, it is less common compared to other symptoms such as dyspnea (difficulty breathing), confusion, or cyanosis (bluish discoloration of the skin and mucous membranes).

B. Dysphagia

Dysphagia, or difficulty swallowing, is not typically associated with hypoxia. It is more commonly seen in conditions affecting the esophagus or neurological disorders affecting swallowing function.

C. Agitation

Manifestations of hypoxia can vary depending on the severity and duration of oxygen deprivation. Agitation is a common finding in hypoxia, particularly in cases of acute or severe hypoxemia. As the body's oxygen supply becomes compromised, the brain may perceive this as a threat, leading to increased anxiety, restlessness, and agitation as the body attempts to compensate for the lack of oxygen.

D. Warm, dry skin

Warm, dry skin is not a typical finding in hypoxia. Instead, hypoxia may lead to peripheral vasoconstriction and cool, clammy skin as the body attempts to conserve oxygen and maintain core body temperature.
