The nurse is assessing internal variables that influence a client's health care beliefs and practices. As part of this assessment, the nurse should consider the client's:

A. One of the primary reasons for administering IV fluids is to correct imbalances in fluid volume or electrolyte concentrations. Examples include correcting dehydration, restoring electrolyte levels (such as sodium, potassium), and addressing fluid losses due to vomiting, diarrhea, or excessive sweating.

B. IV fluids are typically used to increase intravascular volume rather than decrease it. In conditions such as hypovolemia (low blood volume), IV fluids are administered to restore blood volume and improve circulation.

C. Third spacing refers to the abnormal accumulation of fluid in interstitial spaces, which can occur in conditions like sepsis, burns, or trauma. IV fluids are not typically administered to increase third spacing; rather, treatment aims to redistribute fluids and improve fluid balance.

D. Enteral fluids are fluids administered directly into the gastrointestinal tract (via oral or tube feeding). IV fluids are administered directly into the bloodstream and are used when enteral administration is not feasible or sufficient.

D. Congruent communication occurs when verbal and nonverbal messages are consistent with each other. In the scenario, the nurse's direct eye contact, pleasant expression, and verbal statement ("The colostomy looks good") appear to be aligned and supportive of each other. This demonstrates congruence in communication, where both verbal and nonverbal cues are reinforcing a positive message to the client.

A. Introductory communication typically refers to the initial phase of interaction where the nurse establishes rapport, introduces themselves, and sets the tone for the interaction. This does not directly apply to the nurse's actions described in the scenario of changing a client's colostomy bag.

B. Noncongruent communication occurs when there is a mismatch between verbal and nonverbal messages. In this scenario, the nurse makes direct eye contact, has a pleasant expression, and verbally reassures the client that "the colostomy looks good." If these nonverbal cues (eye contact, pleasant expression) are not aligned with the verbal message (reassuring statement), it would be noncongruent communication. However, based on the scenario, it seems the nurse's nonverbal cues (eye contact, pleasant expression) support the verbal message, so this option is less likely.

C. Nonverbal communication includes gestures, facial expressions, eye contact, body language, and tone of voice. In the scenario described, the nurse demonstrates nonverbal communication by making direct eye contact and having a pleasant expression while interacting with the client. Nonverbal communication is an important aspect of nursing care as it conveys empathy, reassurance, and attentiveness to the client's needs.
