25
How do we diagnose epididymitis?  Tx?
NAAT + U/A and culture               If over 35 tx with fluoroquinolone
26
If a male has dysuria and penile discharge, the gram-stain is positive for gonorrhea – dx?  Confirm? Tx?
``` Urethritis               Dx – NAAT for gonorrhea               Tx – Ceftriaxone + azith or doxy  *Must treat all partners regardless of sxs ```
27
How do we treat for chlamydia?
Azithromycin 1g (single dose) or Doxy x 10 days
28
What type of herpes causes oral components vs genital?
HSV1 = oral               HSV2 = genital
29
How do we diagnose and treat herpes?
Dx – PCR               Tx – Acyclovir or valavivlovir (within 72 hours)
30
How do we diagnose and treat Gonorrhea?
Dx – NAAT               Tx – Ceftriaxone
31
How do we diagnose and treat Chlamydia?
Dx – NAAT               Tx – Doxy or Azith
32
How do we diagnose and treat Trichomonas?
Dx – Naat               x – Metronidazole
33
IF we see an increased Cr by .3 or by 50% within 48 hours – what do you think of?  What are the different types?
Acute Kidney Injury 1. Pre-renal 2. Intrinsic 3. Post-Renal
34
Are there any sxs associated with acute kidney injury?
Either Asymptomatic or edema, HTN, fatigue
35
What are the MC causes of pre-renal AKI?
decreased renal perfusion = dehydration, vomiting, diarrhea, CHF               Also, NSAIDs, contrast, and ACE
36
How do you Dx pre-renal AKI?
UA = normal BUN/Cr >20:1 Urine Na <20 Urine Osmol = increased
37
How do treat pre-renal AKI?
Increase renal perfusion via GIVE FLUIDS!
38
If you see muddy brown casts, tubular cell casts, and dysmorphic RBC’s on UA – Dx?
Intrinsic renal disease
39
What is the MC cause of Intrinsic AKI?
ATN (caused by ischemia secondary to prolonged decreased renal perfusion)               *thrombus, scleroderma, malignant HTN or aminoglycosides and sulfonamides
40
How do you dx intrinsic AKI?
UA = granular muddy brown casts, tubular cell casts, dysmorphic RBC’s, hematuria, and/or proteinuria BUN/Cr 10:1 Urine Na >40 Urine Osmol = decreased
41
How do we treat intrinsic AKI?
Treat underlying cause (fluids DO NOT improve ATN)
42
What causes post-renal AKI?  Tx?
Due to outflow obstruction               Tx – Cath or remove obstruction
43
What are some life threatening issues associated with AKI?
Hyperkalemia (dialysis for peaked T waves), uremia, and metabolic acidosis
44
What will cause a false-positive for blood in the urine?
Rhabdo from Hyperkalemia
45
If a pts GFR has been decreased over the past 3 months – dx?  What is a decrease in GFR?
Chronic renal failure               Less than 60 = decreased GFR
46
What other ways can we see kidney damage?
Protein uria, casts, small echogenic kidneys on U/S
47
So a GFR of 45-59 is known as what?
3A
48
So a GFR of 30-44 is known as what?
3B
49
So a GFR of 15-29 is known as what?
4
50
So a GFR of less than 15 is known as what?
5
51
How do we treat chronic renal failure?
start with protein and sodium restriction
52
If someone has CKD and HTN how do we treat them?
ACE/ARB and loop diuretic               *be careful of hyperkalemia!!
53
When we start an ACE what lab finding do we often see?
Transient drop in GFR               *Why you need a baseline Cr and K, followed by a re-check, if Cr increases by over 30% stop ACE
54
CKD is viewed as an equivalent to what?
Coronary artery disease
55
What are some indications for dialysis?
Uremia, significant bleeding, refractory metabolic acidosis, hyperkalemia, pericarditis, and malnutrition, and GFR of 5!
56
What is the normal range for a pH?
7.35-7.45
57
What is normal PCO2?
35-45
58
What’s a normal bicarb?
24-30
59
If the pH is down – what state are you in?
Acidosis
60
If the pH is up – what state are you in?
Alkalosis
61
If both the pH and bicarb are down – what state are you in? Cause?  Tx?
``` Metabolic Acidosis (both go down = metabolic)               MUDPILES               Tx underlying cause ```
62
What does MUDPILES stand for?
Methanol, uremia, DKA, propylene glycol, infection/isonized, lactic acidosis, ethylene glycol/ethanol, and salicylates (ASA)
63
If the pH is low but the bicarb is high – what state are you in?  What can cause it? Tx?
``` Respiratory acidosis               Caused by svere COPD or drug OD               Tx = ventilator support or narcan ```
64
If the pH is up but the bicarb is down – what state?  Cause? Tx?
``` Respiratory alkalosis                Caused by hyperventilation               Tx = breath into a bag ```
65
If the pH is up and the bicarb is up – state? Cause? Tx?
``` Metabolic Alkalosis               Severe vomiting with hypokalemia               Isotonic fluids and electrolytes  ```
66
If your pt has kussmal breathing, tinnitus, and anxiety/delirium – what are you worried about?
Aspirin OD
67
How do we treat aspirin OD?
Bicarb and dialysis
68
If a pt have RUQ for 48 hours and they are jaundiced – what do you think?
Acetaminophen OD
69
What will we see on labs with acetaminophen OD?
Re-draw labs every 4 hours because it can take a long time to see results (AST/ALT, BUN/Cr, Lactate, ABG’s)
70
How do we treat an acetaminophen OD?
Oxygen, cardiac monitor, N-acetylcystine within 8 hours
