What is an incomplete expansion or collapse of a part of the lungs known as?

Choice A rationale

The working phase of the helping relationship is characterized by the nurse and client collaborating to meet specific health goals. When a client complies with orders to get out of bed and sit in a chair, they are actively participating in their recovery and performing the work necessary for rehabilitation. This phase involves problem-solving and the implementation of the care plan. Active participation in physical tasks demonstrates that the client is engaged in achieving the desired health outcomes.

Choice B rationale

This statement is more characteristic of the termination phase of a relationship. The client is reflecting on their progress and expressing satisfaction with the outcomes achieved during their stay. While it shows the goals were met, the act of reflecting on the past journey usually happens when the relationship is coming to a close. The working phase is about the ongoing effort and action rather than the final summary of success after the tasks are largely completed.

Choice C rationale

This action occurs during the orientation phase of the nurse-client relationship. The orientation phase is when the nurse introduces themselves, establishes the parameters of the relationship, and sets the schedule for care. It is the foundation where trust is built and roles are defined. Providing information about shift times is a clerical and introductory task that precedes the actual therapeutic work and goal setting that defines the subsequent working phase of the professional relationship.

Choice D rationale

Learning and using the nurse's name is part of the orientation phase. It signifies that a rapport is beginning to develop and that the client recognizes the nurse as an individual provider. While it is important for establishing a connection, it does not demonstrate the achievement of complex health-related goals or the collaborative work typical of the working phase. It is an early social and professional milestone rather than a sign of active participation in the clinical care plan.

Choice A rationale

Iron is a critical mineral component of the heme group within the hemoglobin molecule, specifically in the ferrous state, which allows for the reversible binding of oxygen molecules. However, iron itself is not the name of the complex formed when oxygen binds to hemoglobin. While iron deficiency leads to reduced oxygen-carrying capacity, the specific physiological term for the oxygen-saturated hemoglobin molecule circulating in the arterial blood is what the question specifically seeks to identify.

Choice B rationale

Pulse oximetry is a non-invasive diagnostic method used to measure the functional oxygen saturation of arterial hemoglobin. It utilizes light absorption characteristics of oxygenated and deoxygenated blood to provide a percentage value, typically between 95.

Choice C rationale

Capnography is the continuous monitoring of the concentration or partial pressure of carbon dioxide in respiratory gases. It provides real-time information about a patient's ventilation, perfusion, and metabolism by measuring end-tidal CO2 levels, which normally range between 35 and 45 mmHg. While it is an essential respiratory monitoring parameter alongside oxygenation, it relates to the excretion of carbon dioxide rather than the specific binding of oxygen to red blood cells for systemic delivery.

Choice D rationale

When oxygen molecules bind to the heme portion of hemoglobin in the pulmonary capillaries, the resulting molecular complex is called oxyhemoglobin. This bright red molecule is responsible for transporting approximately 98.5.
