A client is prescribed isotonic IV hydration for their current fluid balance problem. Which property of isotonic fluid replacement is essential for the nurse to understand?

Isotonic fluid helps the client feel less thirsty when they are NPO.

This type of IV hydration replaces blood volume without affecting intracellular fluid.

Isotonic IV hydration can cause cells to burst if given too rapidly.

This type of IV fluid must be given in an intensive care setting with frequent monitoring of the client's vital signs.

Answer and Explanation

The Correct Answer is B

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.

Correct Answer is C

Explanation

A. A document that the client signs indicating they wish to be an organ donor: This describes an organ donor card or organ donation consent form, not a living will. An organ donor card is a document indicating the individual's wish to donate organs after death to benefit others in need of organ transplants.

B. A medical order that outlines the client's wishes if cardiac or respiratory arrest occurs: This describes a do-not-resuscitate (DNR) order, which is a medical order indicating that the individual does not wish to receive cardiopulmonary resuscitation (CPR) in the event of cardiac or respiratory arrest. It is specific to resuscitation preferences and is different from a living will.

C. A witnessed legal document that describes the client's wishes regarding medical care if unable to speak: This is the correct description of a living will. A living will is a legal document that outlines a person's preferences regarding medical treatment and interventions in the event they become incapacitated and unable to communicate their wishes. It typically addresses preferences for life-sustaining treatments, such as mechanical ventilation, artificial nutrition and hydration, and other medical interventions.

D. A legal document that lists who gets the client's property & belongings before if they cannot communicate: This describes a last will and testament, which is a legal document that outlines how a person's property and assets should be distributed after their death. It does not address medical care preferences or interventions during the person's lifetime.

A. Type of diet B. Cultural considerations C. Gender D. History of onset

Correct Answer is D

Explanation

A. Type of diet: While the type of diet may be relevant to the overall health and well-being of the older adult client, it may not directly contribute to understanding the change in mental status. While nutritional deficiencies or imbalances could potentially impact mental status, other factors are more immediately relevant to assessing the change in mental status.

B. Cultural considerations: Cultural considerations are important in providing holistic care to the older adult client, but they may not directly contribute to understanding the change in mental status. Cultural factors could influence communication styles, beliefs about health and illness, and preferences for care, but they may not be the primary focus when assessing a change in mental status.

C. Gender: Gender may have some relevance to the overall health and well-being of the older adult client, but it may not directly contribute to understanding the change in mental status. While certain gender-related factors, such as hormonal changes or gender-specific health conditions, could potentially impact mental health, they may not be the primary focus when assessing a change in mental status.

D. History of onset: This represents a critical thinking approach because understanding the history of onset of the change in mental status is essential for identifying potential causes and determining appropriate interventions. The timing and circumstances surrounding the onset of the change can provide valuable information about possible contributing factors, such as recent illnesses, medication changes, trauma, or environmental changes. By gathering information about the history of onset, the nurse can engage in critical thinking to formulate hypotheses, prioritize assessments, and develop a plan of care tailored to the client's needs.
