26
A young woman has uncomplicated acute bronchitis which did not respond to antitussives and bronchodilators. What should you do?
Treat with an oral steroid taper
Uncomplicated acute bronchitis should not be treated with antibiotics. Some people get a post-bronchitic cough thought to be due to airway tightness. In these cases, oral steroids can help relieve tightness and cough.
27

the fluoroquinolones
29
For acute viral diarrhea, the best dietary recommendations are ________________.
to eat plain foods (potatoes, rice, bread, crackers, bananas) and to stay hydrated
Dairy and alcohol should be avoided.
30
Talk about the better ways to describe dizziness.
* Light-headedness: feeling like you're about to faint

Describe the progression of symptoms seen in acoustic neuroma.
* First: tinnitus and hearing loss
| * Second: facial numbness and vertigo
32
How can the Dix-Hallpike maneuver be used to differentiate peripheral from central causes of stroke?

33
Vestibular dizziness should be treated with what symptoms?
Antihistamines (e.g., meclizine, diphenhydramine)
34
Describe the sensitivity and specificity of BNP in CHF.
An elevated BNP is extremely sensitive for CHF. If a person has a normal BNP, the odds that they have CHF are near zero.
35
True or false: a normal D-dimer effectively rules out a PE.
True
If the D-dimer is normal, then there is very little chance that the person has a clot.
36
For women with recurrent UTIs in whom preventive measures fail, you can prescribe _____________.
a one-day course of antibiotics for post-coital use
37
Why might you do a cystoscopy in a middle-aged woman with recurrent dysuria and hematuria who had a negative workup for UTI and stones?
Interstitial cystitis!
IC can present with lesions on the bladder.
38
If they give you a story that is highly suspicious for pyelonephritis (dysuria, pyuria, back pain, fever) but then tell you the man has no history of UTIs and a normal urinary tract, then they're trying to clue you in to ____________.
acute prostatitis
39

40
Which of the signs of AOM is least sensitive?
Erythematous tympanic membrane
This can be caused by crying. Bulging, purulence, and immobility to insufflation are all more sensitive.

42
When should Augmentin be used instead of amoxicillin in the treatment of AOM?
When the temperature is above 102
43
What physical exam signs point to cellulitis as opposed to DVT?
Erythema, warmth, and pain (all indications of inflammation)
44
Describe the difference between primary and secondary enuresis.
* Primary enuresis: child has never been dry at night
| * Secondary enuresis: child was dry at night but then started wetting again
45
What is thought to be the cause of enuresis in children?
Immaturity of nocturnal vasopressin release
46
How can you differentiate familial short stature and constitutional growth delay on a growth curve?

| * In FSS, the height and weight go down simulataneously.
47
What other features make fatigue more likely to be depression-related?
Denial of hypersomnolence and weakness
48
Go through PreTest's three categories of fatigue.
* Physiologic (e.g., overwork, lack of sleep, pregnancy)

anal fissure
52
What age criteria warrants further workup of a headache?

53
Which CCB has been shown to be effective in migraine prophylaxis?
Verapamil
| "VErapamil VEnts the pressure."
54
Describe the treatment options for cluster headaches.
• Chronic: but only during the symptomatic period
- Lithium
- Indomethacin

- Oxygen
In general, you wait until the person has a headache and then treat with oxygen. Once the oxygen resolves the headache, initiate a chronic medicine to prevent attacks during the episode. Discontinue the prophylactic medication after the cluster episode ceases.
55
Which sleep aid can be used for middle-of-the-night awakenings?
Zaleplon
It has a shorter half-life than zolpidem and eszopiclone and can thus be taken halfway through the night without causing daytime somnolence.
56
Those with hepatitis A are most infectious _____________.
during the prodromal period – not while jaundiced
57
Anti-HbCAg IgG indicates _____________.
chronicity; that is, if the patient has this, it is not an acute infection
58

Functional incontinence is something that prevents patients from voiding in the bathroom (such as paralysis, bed rest, or severe dementia).
60
A postvoid volume greater than __________ indicates overflow incontinence.
200 mL

Anovulatory
63
Which common medications cause mild hyperprolactinemia?
SSRIs
64
Explain the utility of the progestin challenge (and the next test!).
* If bleeding occurs after progestin withdrawal, then it indicates unopposed estrogen (i.e., PCOS).
* If bleeding does not occur, then it is either outflow tract obstruction or inadequate estrogen production. An estrogen-progestin challenge can differentiate the two.
65
What ophthalmologic findings can be seen in someone with hypertensive emergency?
Papilledema (suggestive of hypertensive encephalopathy)
66
What is the difference between ileus and obstruction?
Obstruction implies a physical blockage of the intestines. Ileus implies paralysis of the bowel.

67
Psychogenic vomiting should be suspected in ________________.
cases in which the patient reports chronic symptoms but does not show signs of dehydration or malnutrition
68
How can you differentiate between osteoarthritis and mechanical injury as causes of neck pain?
* Osteoarthritis: worse after movement; no TTP
| * Mechanical injury: worse after movement; TTP
69

benzoyl peroxide, topical antibiotics, and topical retinoids
78
When initiating isotretinoin, you need to have the patient discontinue what other oral acne agent?

83
Both oral and genital herpes should be treated with _______________.
daily Valtrex
84

preauricular lymphadenopathy
90
You prescribe ciprofloxacin ophthalmic solution for bacterial conjunctivitis. The patient returns three days later and her symptoms have not improved. What's going on and what should you do?
She likely has a bacterial infection from a strain that is resistant to fluoroquinolones. MRSA is a common etiology. Treat with oral Bactrim.

Scleritis
This is common in those with autoimmune disorders.

1) Relocate
2) Immobilize for 7-10 days
3) Physical therapy
96
Describe the causes and symptoms of iliotibial band syndrome.
Repetitive knee flexion activities (like long-distance running) lead to lateral knee pain.
97
Treatment of patellofemoral pain syndrome is through ________________.
strengthening the quadriceps muscles
98
When is an x-ray indicated in the workup of an ankle sprain?
When there is significant tenderness over the malleoli or metatarsals
99
Tilt table testing can reveal what kind of syncope?
Vasovagal
TT testing is valuable when cardiac, metabolic, and neurologic causes of syncope have been ruled out.
100
What is the glabella sign?
Tapping the forehead should cause a person to blink, but after tapping it for 15 times it should stop. (That is a negative sign.) Consistent blinking after 15 times is considered a positive sign and is often seen in Parkinson's disease.
101
Which is the only pharmacologic therapy shown to delay disease progression in Parkinson's disease?
