Q

What happens when you reduce ADH

A

Hypotension:
⬇️ solutes
⬆️ H2O

20
Q

Ranges of regulation of sodium

A

135-145 mEq/L NORMAL
hyperatremia:> 145
Hypoatremia: <135

21
Q

Homeostasis of hyperkalemia

A

⬆️ aldosterone ⬆️ K+ and H+
Then decrease in K+

  • opposite happens with hypokalemia
22
Q

Sign v. Symptom

A

Sign: doctor sees
Symptom: patient experiences

23
Q

Calcium levels

A

Normal: 8.2-10.2
<8.2 hypocalcemia
>10.2 hypercalcemia

24
Q

Magnesium levels

A

Normal: 1.7-2.2
<1.7: hypomagnesemia
>2.2: hyperm

25
What’s stimulates calcium uptake in the intestines
Vitamin D
26
What increases and decreases Ca2+ extracellular levels
Increases: PTH Decreases: calcitonin
27
What did you look at if the electrolytes are in balanced?
Magnesium levels
28
Phosphate levels
Normal: 2.5-4.5 Hypophospatemia: reduced absorption due to vitamin D deficiency Hyperphosphatemia : renal failure, chemotherapy
29
Acids v. bases v. buffers
Acids: release, hydrogen ions HCI Bases: removes hydrogen from a solution OH- Buffers: prevent extreme changes in pH
30
What regulates blood pH?
Respiratory and urinary system
31
What is the normal pH range?
Normal: 7.35–7.45. Acidosis < 7.35. Alkalosis > 7.45.
32
HCO3 buffering system
H2CO3<—> HCO3- + H+ Base Acid
33
What affects respiratory centers?
Carbon dioxide levels and pH
34
What is acidosis in the respiratory system?
Hypoventilation: Retention of CO2 causing blood levels to increase, causing pH to decrease
35
What is hyper ventilation?
Increasing ventilation rate which decreases blood CO2 levels, which then increases pH -Also called alkalosis
36
What is the number one factor in acid/ base
The amount of CO2
37
Does an increase in carbon dioxide contribute to an increase in acids?
True
38
PaCO2 levels
Normal: 35-45 > 45 acidosis < 35 alkalosis
39
HCO3 levels
22-26 normal > 26 alkalosis < 22 acidosis
40
If urinary is acidic, what is respiratory system
It Hass to be basic
41
If respiratory is acidic, urinary Has to be
Asked to be basic
42
Acidosis
⬇️pH +⬆️PaCO2 + norm HCO3=prim respiratory acidosis ⬇️pH + norm PaCO2+ ⬇️HCO3= primary metabolic acidosis (urinary)
43
Alkalosis
⬆️pH + ⬇️PaCO2 + norm HCO3=prim respiratory alkalosis ⬆️pH+ norm PaCO2 + ⬆️HCO3= primary metabolic alkalosis (urinary)
44
What does a fall in base cause
Acidosis
45
If the pH is 7.30, PaCO2 = 40, HCO3 =19. Or what is his acid /base disturbance?
She is primary metabolic acidosis for urinary system
46
PH= 7.50, PaCO2 = 30, HCO3 =24. What is the acid/base disturbance?
Primary respiratory alkalosis
