The nurse is instructing family members of an immunosuppressed client who has been placed in a protective environment to wear gloves and a mask when visiting the client. The nurse is aware that this practice is important to prevent infection transmission from:

C. Before administering a feeding through a gastrostomy tube, it is essential to verify that the tube is patent (open and unobstructed). Tube patency ensures that the feeding formula or medication can flow freely into the stomach or intestines without encountering any blockages or resistance. The nurse should flush the tube with water to check for patency and ensure proper functioning before initiating the feeding.

A. Vital signs are typically assessed for overall health monitoring and to detect any immediate changes in the client's condition. However, they are not specifically required before every feeding via gastrostomy tube unless there are specific concerns about the client's stability.

B. This option is not typically necessary before administering a feeding through a gastrostomy tube. In fact, elevating the head of the bed to at least 30 to 45 degrees is often recommended during and after feeding to minimize the risk of aspiration. This position helps to promote digestion and reduce the likelihood of reflux or regurgitation of the feeding.

D. Assisting the client to a prone (face-down) position is unnecessary and potentially unsafe before administering a feeding through a gastrostomy tube. The recommended position for feeding via gastrostomy tube is typically semi-Fowler's position (elevated head of the bed), which helps prevent aspiration and facilitates digestion.

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.
