What is ascites? What is it an example of?
ascites is a collection of fluid in the abdominal cavity that occurs during liver failure. It is an example of third-spacing
26
Signs of too little volume or extracellular volume deficit
``` weight loss skin tenting dry mucous membranes flat neck veins when lying flat vascular underload (rapid thready pulse, orthostatic hypotension, or low BP) lightheadedness/syncope low urine output ```
27
signs of too much volume or extracellular volume excess
``` weight gain edema vascular overload (bounding pulse, distended neck veins when upright) pulmonary edema dyspnea ```
28
``` weight gain edema vascular overload (bounding pulse, distended neck veins when upright) pulmonary edema dyspnea ```
Signs of too much volume or extracellular volume excess
29
``` weight loss skin tenting dry mucous membranes flat neck veins when lying flat vascular underload (rapid thready pulse, orthostatic hypotension, or low BP) lightheadedness/syncope low urine output ```
signs of too little volume of extracellular volume deficit
30
Hyponatremia
``` sodium less than 135 impaired cerebral function decreased LOC nausea seizures decrease in BP ```
31
``` sodium less than 135 impaired cerebral function decreased LOC nausea seizures decrease in BP ```
hyponatremia
32
Hypernatremia
``` sodium greater than 145 impaired cerebral function decreased LOC thirst (not always in older adults) seizures restrict sodium intake for this patient ```
33
The main function of sodium in the body
body water balance
34
``` Signs and Symptoms are: Low HR Low BP Low RR Decreased DTR ```
HYPERmagnesmia | LOW EVERYTHING
35
Risk factors of HYPERmagnesemia
Increased Mg intake;excessive admin of Mg IV, Mg containing antacids or laxatives Renal Insufficiency
36
Factors contributing to respiratory acidosis
COPD, sleep apnea, opioid toxicity, asthma, anesthesia
37
Factors contributing to metabolic acidosis
diarrhea, renal disease, small intestine illness/surgery, laxative abuse
38
Factors contributing to respiratory alkalosis
hyperventilation, panic, anxiety
39
Factors contributing to metabolic alkalosis
vomiting, NG tube suctioning, bulimia, renal disease
40
impaired cerebral function, decreased LOC, nausea, seizures, decreased BP. Can occur from heat/sweating,
Hyponatremia
41
impaired cerebral function, decreased LOC, thirst (not in older adults), seizures. Sodium intake should be restricted for these pt’s.
hyprernatremia
42
dietary sources of sodium
table salt, processed foods, milk, animal products, eggs, carrots, beets, leafy greens, celery
43
muscle weakness/ flaccid, ABD distention, decreased deep tendon reflexes (DTR), orthostatic hypotension, urinary retention, Patients taking potassium wasting diuretics (lasix or furosemide) should be taught to increase their daily potassium intake.
hypokalemia
44
muscle weakness/flaccid, cardiac dysrhythmias, can lead to cardiac arrest. Hyperkalemia can occur when extensive tissue damage occurs from burns or crush injuries. Severe hyperkalemia causes life threatening cardiac dysrhythmias.
hyperkalemia
45
food sources of potassium
unprocessed foods, fruits, vegetables, fish whole grains, legumes, seeds, and milk products. K+ is lost when food is boiled or blanched, unless you drink the water it was sitting in.
46
increased muscle excitability, muscle cramps, hyperactive reflexes, twitching, laryngo-spasms, carpopedal spasm, tetany, seizures, cardiac dysrhythmias. Can result from any disorder that shifts/moves more calcium into the bone. Removal or injury of the parathyroid gland during a thyroidectomy can cause hypocalcemia.
hypocalcemia
47
decreased muscular activity/ muscle weakness, anorexia, nausea, constipation, diminished reflexes, decreased LOC, cardiac dysrhythmias, formation of kidney stones.
hypercalcemia
48
food sources of calcium
milk/milk products, green vegetables, nuts, soybeans, and grains
49
increased muscular excitability/tetany, insomnia, hyperactive reflexes, muscle cramps, twitching, nystagmus (twitching of the eye which can often result in reduced vision and depth perception), seizures, and cardiac dysrhythmias.
hypomagnesemia
50
Mg deficiency
rare, persistent vomiting and diarrhea, loss of GI fluids, renal disorders, alcoholism, is life threatening.

54
symptoms of dehydration in the elderly
SKin tenting on the forehead and the sternum dry mucous membranes weight loss of 1-2 lbs in a day
55
What is BPH
benign prostate hyperplasia; enlargement of the prostate. The main issue is obstruction of urine flow. usually starts around age 30 and worsens over time.
56
S&S of BPH
``` difficulty voiding nocturia frequent UTI's weak urine stream urine flow is completely blocked ```
57
When the urine backs up into the ureters causing the ureters to dilate. Which is painful and is a result of a complete urine blockage
Hydroureter
58
When urine backs up into the kidneys. It can be painful and is a result of a complete urine blockage
Hydronephrosis
59
the build-up of nitrogen in the blood. result of a complete urine blockage
azotemia
60
Dx tests for BPH
digital rectal exam pressure flow studies ultra sound UAC
61
Tx for BPH
``` Alpha-adrenergic blockers 5-Alpha reductase inhibitors (ARI's) acupuncture saw palmetto Echinacea ```
