A nurse is teaching a graduating nurse about fluid volume deficit. Which of the following concepts about water balance should the nurse explain to the graduating nurse?

The intracellular space contains most of the body's water.

A negative fluid balance occurs when the body takes in more water than the body needs.

When the body loses water, the intravascular space experiences the water loss.

A fluid volume deficit inhibits baroreceptors

Answer and Explanation

The Correct Answer is A

A. The intracellular space contains most of the body's water: The majority of the body's water is found within the cells (intracellular space), accounting for about two-thirds of total body water. This is the primary compartment where water is stored and is critical for cellular function and maintaining homeostasis.
B. A negative fluid balance occurs when the body takes in more water than the body needs: A negative fluid balance refers to a state in which the body loses more water than it takes in, resulting in dehydration or fluid volume deficit. When the body takes in more water than it needs, it results in a positive fluid balance, which could lead to fluid overload or hyperhydration.
C. When the body loses water, the intravascular space experiences the water loss: While the loss of water from the body can affect all compartments, including the extracellular space, the intravascular space (blood vessels) is particularly vulnerable to volume loss, such as in dehydration. However, the primary loss in water occurs from both intracellular and extracellular compartments, not exclusively the intravascular space.
D. A fluid volume deficit inhibits baroreceptors: Fluid volume deficit may affect baroreceptors, which detect changes in blood pressure, but it does not directly inhibit them. In fact, a decrease in fluid volume typically triggers baroreceptors to respond by stimulating mechanisms that attempt to restore fluid balance, such as increasing thirst or activating the renin-angiotensin-aldosterone system to conserve water.

Correct Answer is B

Explanation

A. Resorption of cerebrospinal fluid: Cerebrospinal fluid resorption is primarily regulated by pressure gradients within the brain and the arachnoid villi, not directly by mean arterial pressure.
B. Cerebral blood flow: Mean arterial pressure is a key factor in maintaining adequate cerebral perfusion. The brain requires a consistent blood supply, and if MAP falls too low, cerebral perfusion pressure drops, increasing the risk for brain ischemia and secondary injury after trauma.
C. Regulation of blood pressure: MAP is a measurement derived from blood pressure values, not a mechanism that regulates blood pressure itself. It reflects perfusion status rather than controlling it.
D. The client's intake and output needs: Intake and output are managed through fluid balance and kidney function. While MAP may indirectly influence renal perfusion, it is not the primary determinant of fluid management planning.

A. A client who has coronary artery disease (CAD) and chronic allergies B. A client who has coronary artery disease (CAD) and Bell's palsy C. A client who has coronary artery disease (CAD) and chronic obstructive pulm D. A client who has coronary artery disease (CAD) and chronic diverticulitis

Correct Answer is C

Explanation

A. A client who has coronary artery disease (CAD) and chronic allergies: While chronic allergies can affect respiratory health, they are not as significant a risk factor for complications following CABG surgery as pulmonary diseases like COPD, which directly impact lung function and oxygenation during recovery.
B. A client who has coronary artery disease (CAD) and Bell's palsy: Bell's palsy, a condition that causes temporary facial paralysis, is not directly related to increased risk for complications following CABG surgery. The primary concern following surgery would be more related to cardiovascular and respiratory health rather than neurological conditions like Bell's palsy.
C. A client who has coronary artery disease (CAD) and chronic obstructive pulmonary disease (COPD): COPD significantly increases the risk of complications after CABG surgery due to the impact on lung function. Patients with COPD have reduced oxygenation capacity, making them more vulnerable to respiratory complications such as pneumonia, atelectasis, or prolonged mechanical ventilation.
D. A client who has coronary artery disease (CAD) and chronic diverticulitis: Chronic diverticulitis affects the gastrointestinal system and is generally not a major risk factor for complications following CABG surgery. The client may have a higher risk for GI issues, but respiratory and cardiovascular factors play a more significant role in CABG recovery.
