interstitial fluid

intracellular fluid (ICF)

intravascular fluid

extracellular fluid (ECF)

Answer and Explanation

The Correct Answer is B

a) Interstitial fluid: Interstitial fluid is the fluid that surrounds cells, not the fluid within the cells themselves.

b) Intracellular fluid (ICF): Intracellular fluid makes up about 70% of total body water and is found inside the cells. This is the fluid that plays a key role in cellular functions.

c) Intravascular fluid: Intravascular fluid refers to the fluid within the blood vessels (plasma), which makes up about 5% of total body water.

d) Extracellular fluid (ECF): Extracellular fluid includes both interstitial fluid and intravascular fluid, but it is not the fluid within the cells.

Correct Answer is ["A","B","C","D","F"]

Explanation

a) Daily Weights: Daily weights are an important measure for assessing fluid status, as they can indicate fluid retention or loss.

b) Moisture of oral cavity: The moisture of the oral cavity can be an indicator of dehydration, which affects fluid balance.

c) Intake and Output: Monitoring intake and output is essential for assessing the balance of fluids and electrolytes.

d) Edema: Edema, or fluid retention, is a key sign of altered fluid and electrolyte status.

e) Listen: While listening to lung sounds or heart sounds may provide indirect information about fluid balance, the word "listen" alone is too vague and not a specific parameter for fluid and electrolyte assessment.

f) Skin turgor: Skin turgor is a sign of hydration status. Decreased turgor may indicate dehydration.
