Q

Sterile dressing change wound care key points

A
  • Use clean gloves (off the wall) to remove old dressing, THEN set up sterile field and apply sterile gloves
  • With moistened gauze, clean from the wound and then away to prevent introduction of new bacteria (the wound itself is considered sterile)

__________ losses are things that cannot really be measured like water lost through respiration and the sweat that comes out of skin
Insensible
26
When calculating I&Os, ice chips are recorded as
Half their volume (ex: 100 mL of ice = 50 mL of water)
27
S/S of fluid volume deficit
- Hypotension - Tachycardia - Weak, thready pulse
28
Labs associated with fluid volume deficit
Elevated: Hct, blood osmolality, BUN, urine specific gravity, urine osmolality
29
Treatment for fluid volume deficit
IV fluids, usually isotonic
30
S/S of fluid volume overload
- weight gain - edema - tachycardia - hypertension - dyspnea, crackles in lungs - JVD - bounding pulses
31
Labs associated with fluid volume overload
Decreased: Hct, Hgb, serum osmolality, urine specific gravity (dilute everything)
32
Treatment for fluid volume overload
Diuretics, paracentesis
33
Weight gain to report to provider
1-2 lbs in 24 hr OR 3 lb in a week

What are some of the causes for Hypercalcemia?
Prolonged immobility, hyperparathyroidism
36
What are some of the causes for hypocalcemia?
Hypoparathyroidism, decreased vitamin D intake, diarrhea
37
Positive Chvostek and Trousseau’s signs indicate
Hypocalcemia
38
Magnesium normal range
1.5-2.5 mEq/L
39
Deep tendon reflexes are __________ with hypermagnesemia and __________ with hypomagnesemia
Decreased; increased
40
A patient with hypomagnesemia is at risk for

PH above 7.45
Alkalosis
49
Normal PCO2
35-45
50
The higher the CO2, the more _________. The lower the CO2, the more _________.

51
Normal HCO3
21-28
52
Acid base imbalance characterized by pH greater than 7.45 and PaCO2 less than 35
Respiratory alkalosis
53
Major cause of respiratory alkalosis
Hyperventilation (r/t anxiety, pain, neurological disorder or injury)
54
Acid base imbalance characterized by pH less than 7.35 and PaCO2 greater than 45
Respiratory acidosis
55
Causes of respiratory acidosis
Air trapping disease (COPD), oversedation (anesthesia, opioids, Benzos, mechanical ventilation)
56
Treatment for respiratory alkalosis
Calm the patient down, have patient breathe into cupped hands or paper bag to rebreathe CO2 to increase amount in blood
57
Treatment for respiratory acidosis
Encourage patient to breathe more frequently, adjust ventilator settings, sternal rub to arouse patient if over sedated, administering antidote for overdose (flumazenil, naloxone)
58
Acid base imbalance characterized by pH greater than 7.45 and HCO3 greater than 28
Metabolic alkalosis
59
Causes of metabolic alkalosis
Antacid overdose, vomiting, excessive GI suctioning (such as by NGT)
60
Acid base imbalance characterized by pH less than 7.35 and HCO3 less than 21
Metabolic acidosis
61
Metabolic acidosis is common in patients with
DKA, kidney failure, excessive diarrhea
62
Treatment for metabolic acidosis
Depends on cause: Antiemetics (if d/t vomiting), stop antacids, insulin for DKA
