Q

What does it mean that albumin has pulling power?

A

Q

What is SIADH?

A

condition in which the body makes too much antidiuretic hormone (ADH). This hormone helps the kidneys control the amount of water your body loses through the urine. SIADH causes the body to retain too much water.

Q

What is diabetes inspidus?

A

causes an imbalance of fluids in the body. This imbalance leads you to produce large amounts of urine. It also makes you very thirsty even if you have something to drink.
A disorder of salt and water metabolism marked by intense thirst and heavy urination.
Diabetes insipidus occurs when the body can’t regulate how it handles fluids. The condition is caused by a hormonal abnormality and isn’t related to diabetes.

Study These Flashcards
A

Capillary permability

25
What is another example of third spacing?
Pleural effusion
26
What are the manifestations of fluid volume excess?
``` Headache, confusion, lethargy Peripheral edema Jugular vein distention S3 sound Bounding pulse Hypertension Central venous pressure Polyuria Dyspnea Crackles Pulmonary edema Muscle spasms Weight gain Seizures Coma ```
27
What are the manifestations of fluid volume deficit?
``` Resetlessness Drowsiness Lethargy Confusion Thirst Dry mucous membranes Cold clammy skin Decreased skin turgor Decreased capillary refill Postural hypotension Tachycardia Decreased CVP Decreased urine output Tachypnea ```
28
What is a S3 heart sound called?
A Gallop
29
What is CVP?
Central venous pressure
30
What does fluid volume excess lead to seizures and coma?
Due to the hyponatremia
31
Who has a decreased thirst mechanism?
The elderly
32
To measure a daily weight it needs to be what three things?
Same scale Same clothes Same time of day
33
What are nursing management of FV imbalances
Daily weights I&Os Lab findings
34
What are three labs to pay attention to for a patient with FV imbalances?
BUN Na+ Hct
35
When a patient has a FV balance, their labs might be...
False high or low
36
What else can we measure that related to FV?
Urine and serum osmolality
37
What does a urine and serum osmolality measure?
How concentrated the urine and serum is
38
If a patient has mild fluid volume deficit...
may encourage oral rehydration
39
If a patient has severe fluid volume deficit...
May replace volume with blood products or balance IV solutions
40
If a patient has fluid volume excess, what might we do?
Restrict fluids
41
With fluid volume excess, what will the heart rate sound like?
Bounding
42
With fluid volume deficit the pulse will sound...
Faint, weak, thready
43
With fluid volume deficit, why does the pulse become tachycardic?
Trying to keep up with drop in blood pressure
44
What is a way you can measure if someone has fluid volume deficit concerning blood pressure?
See if they have orthostatic hypotension
45
What brings a patient into the hospital when they have fluid volume overload?
Pulmonary edema, they can't breathe
46
What are patient safety concerns?
Change in LOC | Orthostatic hypotension
47
Why would a patient with FVE or FVD have a change in LOC?
Due to the very high or very low levels of sodium in the blood
48
What can be delegated to a UAP when it comes to FV imbalances?
``` Obtain daily weights and vital signs Offer frequent oral care Record accurate intake and output Perform skin care and frequent position changes Elevated extremities Encourage oral fluids ```
