,Module 8 Exam
Question 1
A Clinician Performs A Full Hydration Assessment On A Patient. The Skin Turgor Test
Showed An Immediate Response, Mucous Membranes Look Moist, And Capillary Refill
Is Under 2 Seconds. What Does This Indicate About The Patient's Hydration Status?
A. Normal
B. Overhydrated
C. Dehydrated
ANS. A.
Explanation: Immediate Return Of The Skin, Moist Mucous Membranes, And Capillary
Refill Under About 2 Seconds Are Findings Consistent With Adequate Hydration And
Normal Peripheral Perfusion.
Question 2
What Role Do Baroreceptors Play When A Patient Is Dehydrated?
A. They Increase Blood Volume By Releasing Fluid From Tissues.
B. They Detect The Drop In Blood Pressure And Trigger Sympathetic Responses To
Increase Heart Rate.
C. They Stimulate Parasympathetic Activity To Slow The Heart Rate.
D. They Directly Cause Blood Vessels To Dilate.
ANS. B.
Explanation: Dehydration Can Decrease Blood Volume And Blood Pressure.
Baroreceptors Detect The Reduction In Arterial Pressure And Contribute To Sympathetic
Responses That Increase Heart Rate And Vascular Tone.
Question 3
Tonicity Has No Impact On Cell Integrity Because It Does Not Affect Water Movement
Into Or Out Of The Cell.
,A. True
B. False
ANS. B.
Explanation: Tonicity Describes How A Solution Affects Water Movement Across A
Cell Membrane. A Hypertonic Solution Can Cause Cells To Lose Water And Shrink,
Whereas A Hypotonic Solution Can Cause Cells To Gain Water And Swell.
Question 4
A Patient Is Given An Oral Rehydration Solution That, Due To A Formulation Error,
Contains A Higher Concentration Of Solutes Than Normal Body Fluids. What Type Of
Solution Was Ingested And How Does The Resulting Fluid Shift Affect Cells?
A. Isotonic: No Change To The Cells
B. Hypertonic: Water Moves Out Of The Cells, Causing Them To Shrink
C. Hypotonic: Water Moves Into The Cells, Causing Them To Swell
D. Hypotonic: Water Moves Out Of The Cells, Causing Them To Shrink
ANS. B.
Explanation: A Hypertonic Solution Has A Greater Effective Solute Concentration Than
The Cell. Water Moves Toward The Higher Solute Concentration, Causing Water To
Leave The Cells And The Cells To Shrink.
Question 5
How Does Proper Fluid Balance Directly Influence Electrolyte Balance In The Body?
A. By Enhancing The Secretion Of Hormones That Degrade Electrolytes
B. By Completely Preventing The Reabsorption Of Sodium In The Kidneys
C. Through The Suppression Of Kidney Function
D. By Only Increasing The Concentration Of Potassium In The Extracellular Fluid
E. The Amount Of Fluid In A Compartment Will Affect The Distribution And
Concentration Of Electrolytes
ANS. E.
Explanation: Electrolyte Concentration Depends Partly On The Amount Of Water In A
Body-Fluid Compartment. Changes In Water Balance Can Therefore Change Electrolyte
,Concentrations Even When The Total Amount Of An Electrolyte Has Not Changed
Substantially.
Question 6
Proper Fluid Balance Is Necessary To Maintain Optimal Cellular Functioning By
Ensuring That Cells Are Adequately Hydrated, Which Supports Enzymatic Reactions,
Nutrient Uptake, And Waste Removal.
A. True
B. False
ANS. A.
Explanation: Adequate Water Is Essential For Cellular Chemical Reactions, Transport
Processes, Nutrient Delivery, And Removal Of Metabolic Wastes.
Question 7
Which Clinical Assessment For Hydration Status Measures How Long It Takes For
Blood To Re-Perfuse Tissue After Pressure Is Applied?
A. Mucous Membrane Moisture
B. Respiratory Rate
C. Blood Pressure
D. Skin Turgor
E. Capillary Refill Time
F. Heart Rate
ANS. E.
Explanation: Capillary Refill Time Assesses Peripheral Perfusion By Measuring How
Quickly Normal Color Returns To Compressed Tissue After Pressure Is Released.
Question 8
Which Body-Fluid Compartment Contains The Largest Percentage Of Total Body Water?
A. Plasma
B. Intracellular Fluid
,C. Interstitial Fluid
D. Transcellular Fluid
ANS. B.
Explanation: Most Body Water Is Located Inside Cells, Within The Intracellular Fluid
Compartment.
Question 9
Which Of The Following Is The Major Cation In Extracellular Fluid?
A. Potassium
B. Magnesium
C. Sodium
D. Phosphate
ANS. C.
Explanation: Sodium Is The Major Positively Charged Ion In Extracellular Fluid.
Question 10
Which Electrolyte Is The Major Cation Inside Cells?
A. Sodium
B. Potassium
C. Calcium
D. Chloride
ANS. B.
Explanation: Potassium Is The Principal Intracellular Cation.
Question 11
Which Hormone Promotes Water Reabsorption By The Kidneys?
A. Insulin
B. ADH
C. Thyroxine
D. Glucagon
ANS. B.
, Explanation: Antidiuretic Hormone, Or ADH, Increases Water Reabsorption In The
Kidneys, Helping Conserve Body Water.
Question 12
A Person Loses A Significant Amount Of Water Through Sweating Without Replacing
It. Which Condition Is Most Likely?
A. Dehydration
B. Hyperhydration
C. Edema Caused By Excess Water
D. Hypoglycemia
ANS. A.
Explanation: Excessive Water Loss Without Adequate Replacement Produces A Fluid
Deficit.
Question 13
Which Organ Plays The Primary Role In Regulating Fluid And Electrolyte Balance?
A. Heart
B. Kidneys
C. Pancreas
D. Spleen
ANS. B.
Explanation: The Kidneys Regulate Water, Electrolytes, And Acid-Base Balance By
Adjusting Reabsorption And Excretion.
Question 14
Which Process Describes The Movement Of Water Across A Selectively Permeable
Membrane Toward The Area With Greater Effective Solute Concentration?
A. Filtration
B. Diffusion
C. Osmosis
D. Active Transport
