Q

T/F: As an adult ages, the thirst mechanism declines

A

T

*In a client with an altered level of consciousness, this can increase the risk of dehydration and high serum osmolality
A poor intake of water (i.e only 2 glasses) could indicate a loss of the thirst response, which occurs as a normal age-related change.

Q

_____ _____ comes first for fluid volume deficit

A

GI Assessment

24
Q

The most common cause of fluid volume deficit is excessive loss of _____ _____, which can result from vomiting, diarrhea, suctioning, intestinal fistulas, or intestinal drainage.

A

gastrointestinal fluids

25
Q

Low potassium: Hypokalemia

What to do?

A

encourage to consume potassium-rich foods. Which would include: bananas.

26
Q

Nursing Assessment for Infant

A

sunken Fontanel for fluid deficit

27
Q

Nursing Assessment:

The nurse is concerned that a client with a fluid imbalance is at risk for an _____ _____ _____.

A

alteration in perfusion

28
Q

Nursing Assessment:

Data indicates that the client is experiencing an alteration in perfusion may include:

A
  • Peripheral pulses present and are they full
  • Capillary refill of nail beds 3 seconds
  • Are they Oriented to person, place, and time
  • Low BP
  • possibly an elevated pulse as a compensatory measure
29
Q

Nursing Assessment:
Fluid Volume Deficit:

What happens?

A

The internal vasoconstrictive compensatory reactions within the body are responsible for the symptoms exhibited (tachycardia; pale, cool skin; and a decreased urine output.) The body naturally attempts to conserve fluid internally specifically for the brain and heart.

*Avoid diuretics, they would cause further fluid loss, and is contraindicated.

30
Q

T/F: Edema increases the client’s risk for impaired skin integrity, especially feet, coccyx areas.

A

T

31
Q

First place you’ll notice a change when body is low on fluid

A

in the vessels

*hypovolemia)

32
Q 
Vital Signs with someone with Hypovolemia:
Pulse: 
Temperature: 
BP: 
Respirations: 
Central Veinous Pressure: 
Cap refill: 
Cognitive: 
GI: 
Renal: 
Skin:
A 
Pulse: racing
Temperature: elevated
BP: low = weaker pulse
Respirations: faster
Central Veinous Pressure: decreased
Cap refill: sluggish
Cognitive: dizziness/weakness
GI: thirsty, acute wt. loss
Renal: decreased urine volume
Skin: cool/clammy/pale

….initial orthostatic hypotension…lead to a hypotensive state

33
Q 
Vital Signs with someone with Hypervolemia:
Heart Rate: 
BP: 
Central Veinous Pressures: 
Cognitive: 
GI: 
Respiratory:
A

Opposite of Hypovolemia

Heart Rate: fast, because there’s so much fluid = easy to feel pulse
BP: increase
Central Veinous Pressures: increase
Cognitive: Confusion, Weakness, edema
GI: weight gain
Respiratory: pulmonary edema (as it leads to Heart Failure)

34

fluid volume overload

sodium sensitivity

35
Q

The _____ measures the volume of whole blood that is composed of RBCs

A

37% to 47%

37
Q

The hematocrit level will _____ in overhydration

A

decrease

An increase in serum osmolality indicates a _____ _____ _____; a decrease reflects _____ _____ _____

A

fluid volume deficit

fluid volume excess.

41
Q

Serum potassium is _____ an electrolyte used to determine an alteration in fluid balance. _____ _____ values would be more appropriate

A

not

Serum sodium

42
Q

_____: can occur from immobility. Ambulation of the client helps to prevent leaching of calcium from the bones into the serum.

A

Hypercalcemia

43
Q

_____: The client will need additional dietary phosphorus. Providing phosphorus-rich foods such as milk and yogurt is a good way to provide that additional phosphorus..

A

Hypophosphatemia

44
Q

Client Education for _____ _____ _____: the electrolyte will need to be restricted, in the form of a low-sodium diet, and diuretics provided. Diuretics will remove excess fluid being held in the body because of the extra sodium.

A

elevated sodium level

45
Q

_____ _____: Monitoring of heart rate and rhythm would be more appropriate with a potassium imbalance.

A

Potassium imbalances

46
Q

_____ _____ _____: Elevating the head of the bed would be appropriate if the client were demonstrating signs of fluid volume overload..

A

Fluid Volume Overload

47
Q

Client Education: Low-sodium salt substitutes are not really _____. They may contain half as much sodium as regular salt. The client should be instructed to use salt substitutes sparingly because larger amounts often taste bitter instead of salty. Clients should be instructed to read food labels for the amount of sodium in the food item. Baking soda and baking powder contain sodium and should be restricted on a sodium-restricted diet. In place of salt or salt substitutes, the client should be instructed to use herbs, spices, lemon juice, vinegar, and wine as flavoring when cooking.

A

sodium-free

48
Q

For fluid and electrolyte imbalance. Initiate _____ _____

A

intravenous therapy

A

Fluid Volume Excess

51
Q

A

Fluid Volume Excess

52
Q

The client on hemodialysis is expected to have a reduction of _____ _____

A

extracellular fluid

53
Q

_____ is vital in regulating muscle contraction and relaxation.

A

Calcium

54
Q

_____ controls and regulates water balance in the body.
