Pathophysiology Week 5 Questions with 100% Verified Correct Answers What occurs during osmosis?Water moves from an area of lower solute concentration to area of higher solute concentration Sodium ions move through a semipermeable membrane Water moves from an area of higher solute concentration to an area of lower solute concentration Chloride ions follow the movement of sodium ions to a region of low concentration - Correct Answer Water moves from an area of lower solute concentration to area of higher solute concentration What is the difference is osmotic pressure between the two bottles of cola below?The osmotic pressure is the same between both bottles The bottle on the right has higher osmotic pressure There is no osmotic pressure The bottle on the left has lower osmotic pressure - Correct Answer The osmotic pressure is the same between both bottles Which hormones will the body use when there is too much fluid (fluid overload) or too little fluid (dehydration)? (Select all that apply.) Atrial natriuretic peptide Aldosterone Anti-diuretic hormone Oxytocin - Correct Answer Atrial natriuretic peptide Aldosterone Anti-diuretic hormone The hormones aldosterone and ADH both have an important function in which aspect of homeostasis?Stimulation of a conscious desire for water 1 / 3
The regulation of acid concentration in the body The activity of buffer systems Fluid balance in the body - Correct Answer Fluid balance in the body When the osmoreceptors detect a decreased blood volume and increased blood concentration of salt what function increases in the body?Secretion of saliva Progesterone secretion Kidney activity Thirst - Correct Answer thirst Other than measuring fluid intake and output, how can fluid changes be accurately measured in the body? (Select all that apply.) Urinary frequency Weight Blood pressure EKG Fluid challenge - Correct Answer Urinary frequency weight Identify whether the signs and symptoms below relate to mild/moderate, or severe dehydration.Thirst Dry, warm skin Feeling dizzy Muscle cramps Sunken eyes Dry or sticky mouth Dry, cool skin Fainting 2 / 3
Rapid heartbeat - Correct Answer Mild to Moderate:
Thirst, muscle cramps, dry or sticky mouth, dry, cool skin
Severe:
Dry, warm skin, feeling dizzy, sunken eyes, fainting, rapid heartbeat Match the type of dehydration with the correct definition below. - Correct Answer Isotonic - The interpretation of the patient's lab work indicated they lose fluid and electrolytes equally.Hypotonic - The interpretation of the patient's lab work indicated they lost more electrolytes than fluid were lost.Hypertonic - The interpretation of the patient's lab work indicated they lost more fluid than electrolytes were lost.Why are babies and older adults at higher risk of dehydration? Select all that apply.Older adults are not focused Both babies and older adults lack fluid reserves in the body Babies cry a lot Babies' inability to vocalize Decreased thirst sensation in older adults - Correct Answer Both babies and older adults lack fluid reserves in the body Babies' inability to vocalize Decreased thirst sensation in older adult Based on what you know about - Correct Answer Hypertonic Based on the assessment data below, what hypothesis can be made about her underlying condition?She should eat at home more often.Her diet contains too much sodium.She has food poisoning.She is dehydrated. - Correct Answer She is dehydrated
