A client is admitted to the medical-surgical unit with a chief complaint of prolonged vomiting over the past 24 hours. Based on the arterial blood gas (ABG) results of pH 7.5. PaCO2 36, HCO3 40, the nurse determines that the client is experiencing:

B Leaning away from the client can convey disinterest, distraction, or a lack of engagement. It creates physical distance and may inhibit the client from feeling heard or valued. Thus, leaning away from the client can be a barrier to active listening as it diminishes the nurse's ability to fully attend to and understand the client's message.

A. An open posture, where the nurse's body is facing the client with arms uncrossed and relaxed, signals openness and receptivity. It encourages communication and shows the client that the nurse is engaged and attentive. Therefore, an open posture promotes active listening rather than serving as a barrier.

C. Eye contact is essential for effective communication and active listening. It demonstrates attentiveness, interest, and respect. Establishing eye contact helps the nurse to connect with the client and encourages them to continue sharing their thoughts and feelings. Therefore, eye contact supports active listening rather than hindering it.

D. Sitting squarely facing the client promotes engagement and shows that the nurse is focused on the client. It facilitates direct communication and helps the nurse to observe the client's nonverbal cues effectively. This posture encourages open dialogue and supports active listening rather than acting as a barrier.

B. Deep breathing and coughing exercises help to maintain lung expansion and prevent atelectasis (collapse of lung tissue), clear secretions from the airways, which can reduce the risk of respiratory infections like pneumonia, improve oxygenation and ventilation-perfusion matching in the lungs. Additionally, deep breathing exercises can stimulate circulation indirectly by improving oxygenation and gas exchange, which can benefit circulatory function.

A. Massaging bony areas can help prevent pressure ulcers (bedsores) in immobile patients, but it does not directly improve respiratory or circulatory functions. While skin integrity is important, it does not address the physiological needs of respiratory and circulatory systems.

C. While nutrition is important for overall health, especially in a nonresponsive client who may not be able to feed themselves orally, tube feedings primarily address nutritional needs and do not directly impact respiratory or circulatory functions. They are important for preventing malnutrition and supporting recovery, but they do not specifically target the goals of improving respiratory or circulatory functions.

D. Changing positions regularly is crucial for preventing complications such as pressure ulcers and maintaining skin integrity. It can also aid in improving circulation by relieving pressure on vulnerable areas and promoting blood flow. Proper positioning can optimize respiratory function by preventing pooling of secretions and improving lung ventilation. Additionally, positional changes encourage movement of the diaphragm and chest wall, which aids in ventilation and gas exchange.
