Q

Why does HHS happen more often in the elderly?

A

Decreased kidney function which leads to decreased ability for the kidneys to re absorb the glucose which leads to increased glucose levels or HHS. DEHYDRATION also leads to decreased volume which further reduces glomerular filtration rate and casing glucose levels to rise.

100
Q

What is the difference between the parenteral and oral or intranasal desmopressin forms?

A

Parenteral from is 10x stronger.

101
Q

What is the nursing management for a patient with DI?

107
Q

What are the medical interventions for SIADH?

A

Restricting fluid intake.
Promoting excretion of water.
Replacing lost NA
Interfering with the action of ADH

108
Q

What are nursing interventions for SIADH?

A

Monitoring response to therapy
Preventing complications
Teaching the patient about fluid restrictions and drug therapy
Preventing injury
Measure I&O
Daily weight greater than 2.2lbs(1L/1000mL of fluid) is concern
Frequent oral rinses

109
Q

Why is fluid restriction essential for SIADH?

A

Fluid intake further dilutes plasma NA levels. In some cases fluid intake may be kept as low as 500 to 1000mL per day.
USE SALINE INSTEAD OF WATER FOR EVERYTHING

110
Q

What is drug therapy with patient who have hyponatremia with SIADH?

A

Tolvaptan ORAL or conivaptan IV
VASOPRESSIN ANTAGONISTS
Promote water excretion WITHOUT NA loss.
TOLVAPTAN BBW: rapid INCREASE in NA levels greater than 12/24hr can cause CNS demyelination that can lead to death. ALSO high doses or doses longer than 30 days SIGNIFICANT risk for liver failure and death.
ONLY ADMINISTER IN HOSPITAL SETTING

111
Q

What is the drug therapy for patient who have near normal NA levels or heart failure and SIADH?

A

Diuretics: be careful for further NA loss.
Demeclocycline: oral antibiotic may also help correct disturbed fluid and electrolytes

112
Q

What solution is used to treat SIADH when NA levels are very low?

A 
HYPERTONIC SALINE (3% NaCL) 
Give IV cautiously because my add to existing fluid overload and promote heart failure.
113
Q

What can ANY patients response to therapy lead to?

A

Fluid overload which leads to pulmonary edema and heart failure.

114
Q

What is the older adult with SIADH at risk for with these ________ secondary diseases?

A

With cardiac problems, kidney problems, or liver problems, the older adult is at great risk for fluid overload.

115
Q

What are the s/sx of fluid overload? How often do you assess?

A 
Bounding pulse
Distended neck veins
Crackles in lungs
Increasing peripheral edema
Reduced urine output 
 AT LEAST EVERY 2hrs

Pulmonary edema can occur VERY QUICKLY and can lead to death.

If these signs are present NOTIFY THE HCP IMMEDIATELY

116
Q

What is critical when serum NA levels fall below 120 in patients with SIADH?

A

PROVIDING SAFE ENVIRONMENT
Possible neurological changes and risk for seizures increases.
assess neuro changes and subtle changes such as muscle twitching.
Check A&Ox3 EVERY 2 HOURS
Reduce environmental noise and lightening to prevent overstimulation.

117
