The client's urine is cloudy, amber, and has an unpleasant odor. The nurse should make the inference that the client may have:

A. Responsibility: Responsibility refers to the duty or obligation to fulfill one's role or tasks appropriately. While advocating for the client may be considered a responsibility of the nurse, the specific action described in the scenario—calling the insurance company to strongly explain the client's need for rehabilitation—is more accurately categorized as advocacy.

B. Confidentiality: Confidentiality pertains to protecting the privacy and confidentiality of patient information. The scenario does not involve the disclosure of confidential information but rather advocating for the client's needs regarding their rehabilitation placement.

C. Social justice: Social justice involves promoting fairness, equality, and equitable access to resources and opportunities for all members of society. While advocating for the client may align with principles of social justice, the specific action described in the scenario—calling the insurance company to argue for the client's rehabilitation placement—is more directly related to individual advocacy rather than addressing broader societal inequalities.

D. Advocacy: Advocacy refers to actively supporting and speaking up for the rights, needs, and interests of others. In this scenario, the nurse advocates for the elderly client by calling the insurance company to strongly explain why the client needs to go to a rehabilitation facility despite the facility's refusal. This action demonstrates the nurse's commitment to ensuring the client receives appropriate care and support.

A. Isotonic fluid helps the client feel less thirsty when they are NPO: While isotonic fluids can help maintain hydration status, they do not directly address the sensation of thirst. Isotonic fluids replace extracellular fluid volume and help maintain electrolyte balance but do not affect the sensation of thirst.

B. This type of IV hydration replaces blood volume without affecting intracellular fluid: This is the correct property of isotonic fluid replacement. Isotonic IV fluids have a similar osmolarity to extracellular fluid and thus replace fluid volume without significantly impacting the distribution of water between intra- and extracellular compartments. They are effective for expanding intravascular volume without causing a significant shift of water into or out of cells.

C. Isotonic IV hydration can cause cells to burst if given too rapidly: Isotonic IV fluids have the same osmotic pressure as blood plasma and therefore do not cause cells to burst when administered at appropriate rates. It is hypertonic solutions that can cause cells to shrink or swell due to osmotic imbalances.

D. This type of IV fluid must be given in an intensive care setting with frequent monitoring of the client's vital signs: While isotonic fluids are commonly used in various clinical settings, including intensive care, they do not inherently require administration in an intensive care setting with frequent monitoring of vital signs. Isotonic fluids are often administered in routine medical-surgical settings for various fluid balance problems.
