Frage 2
Frage
Why do older adults generally have less total body water than younger adults?
Antworten
-
As functional cells die during the aging process, less water is needed.
-
The muscle mass of older adults is smaller than the muscle mass of younger adults.
-
Older adults have a smaller extracellular fluid to intracellular fluid ratio than younger adults.
-
The plasma volume of older adults is decreased to reduce the risk for excess fluid volume and heart failure.
Frage 3
Frage
Which clinical manifestation supports the concept that filtration is directly related to hydrostatic pressure?
Antworten
-
Capillary refill is faster in fingers than in toes.
-
Central venous pressure is lowest in the right atrium.
-
Pitting edema is usually detected first in dependent areas.
-
Systolic blood pressure is higher than diastolic blood pressure.
Frage 4
Frage
When evaluating the hydration status, the nurse observes tenting of the skin on the back of the 87-year-old client’s hand when testing the skin turgor. What is the nurse’s best action?
Antworten
-
Notify the physician.
-
Examine dependent body areas.
-
Assess turgor on the client's forehead.
-
Document the finding as the only action.
Frage 5
Frage
What effect would an infusion of 200 mL of albumin have on a healthy client's plasma osmotic and hydrostatic pressures?
Antworten
-
Increased osmotic pressure, increased hydrostatic pressure
-
Increased osmotic pressure, decreased hydrostatic pressure
-
Decreased osmotic pressure, increased hydrostatic pressure
-
Decreased osmotic pressure, decreased hydrostatic pressure
Frage 6
Frage
Why does pulmonary edema form in a client who has left-sided heart failure?
Antworten
-
Increased blood volume in pulmonary vessels, increased blood osmotic pressure
-
Increased blood volume in pulmonary vessels, decreased blood osmotic pressure
-
Increased blood volume in pulmonary vessels, increased blood hydrostatic pressure
-
Increased blood volume in pulmonary vessels, decreased blood hydrostatic pressure

Frage 11
Frage
How is the process of active transport beneficial to human living systems?
Antworten
-
Active transport moves substances against a concentration gradient, allowing fluid compartment volume ionic differences to be maintained.
-
Active transport allows the fluid lost at the capillary–interstitial compartment interface to be returned by lymph flow to the systemic circulation.
-
When diffusion is limited by membrane impermeability, active transport maintains homeostasis of osmolarity across all body fluid compartments.
-
When osmosis cannot occur during periods of anoxia, active transport facilitates movement of glucose across cell membranes so that energy production is not disrupted.
