Random Flashcards
Hallmark of re-feeding syndrome
Hypophophatemia
Most sensitive clinical test and initial test for ACL tear
Lachman test
anterior drawer test is next
Hoarseness of voice not resolved in 3 months. What to do?
Laryngoscopy
initial management of hypercalcemia of malignancy
fluid replacement with normal saline.
You need to correct the volume depletion that is present and to enhance renal calcium excretion BEFORE giving IV pamidronate (to help excrete the calcium).
brown to black leopard spotting of the colonic mucosa.
benign condition
results from abuse of anthraquinone laxatives.
Stop medication.
When should colon cancer screening start for those with affected relative that was diagnosed?
How often should they be rescreened if normal?
at age 40, or 10 years before the earliest age at which an affected relative was diagnosed (whichever comes first) and be rescreened every 5 years.
Several drugs are associated with drug-induced pleural disease or drug-induced lupus pleuritis. What are they?
lupus pleuritis- hydralazine, procainamide, and quinidine.
pleural disease - amiodarone, bleomycin, bromocriptine, cyclophosphamide, methotrexate, minoxidil, and mitomycin.
Drugs to avoid in Wolff-Parkinson-White syndrome.
What is the treatment of choice?
Adenosine, digoxin, and calcium channel antagonists
(blocks conduction through AV node, which may increase the ventricular rate paradoxically, initiating ventricular fibrillation.
Procainamide (class III antiarrhythmic medications will slow AP conduction, facilitating blockage of SVT)
Metformin (Glucophage) should be stopped prior to what test, and withheld until 48 hours after completion of the test?
CT angiography
Since even a temporary reduction in renal function, such as occurs after pyelography or angiography, can cause lactic acidosis in patients taking metformin, the drug should be discontinued 48 hours before such procedures and restarted 48 hours after the procedure if renal function is normal.
Guidelines for the management of adults with hospital-acquired, ventilator-associated, and healthcare-associated pneumonia.
Hospitalized versus those that do not need to be hospitalized.
Hospitalized patients
- its empiric coverage MRSA and Pseudomonas aeruginosa
- antipseudomonal cephalosporin (cefepime or ceftazidime), an antipseudomonal carbapenem such as imipenem or meropenem, or an extended-spectrum β-lactam/β-lactamase inhibitor such as piperacillin/tazobactam, PLUS an antipseudomonal fluoroquinolone such as levofloxacin or ciprofloxacin, or an aminoglycoside such as gentamicin, tobramycin, or amikacin, PLUS an anti-MRSA agent (vancomycin or linezolid).
Those that do not require hospitalization
-Ceftriaxone and azithromycin or levofloxacin alone
Treatment for severe osteoporosis in men, for patients with multiple osteoporosis risk factors, or for patients with failure of bisphosphonate therapy
Teriparatide
Pharmacological prevention of acute mountain sickness:
Acetazolamide (contraindicated in patients with a sulfa allergy)
Use Dexamethasone in those with a sulfa allergy
most common drug-related cause of acute interstitial nephritis.
Antibiotics, especially penicillins, cephalosporins, and sulfonamides.
Corticosteroids may be useful for treating this condition.
Contradictions:
Metformin
Pioglitazone
Metformin- CI in patients with renal insufficiency.
Pioglitazone can cause fluid retention and therefore would not be a good choice for a patient with cardiomyopathy.
HPV vaccine
not recommended for:
- those over 26.
- pregnant.
Tdap vaccine
administered to patients 65 years and older who have close contact with an infant less than 1 year.
Ehrlichiosis versus Malaria
Ehrlichiosis causes thrombocytopenia
Malaria causes hemolytic anemia.
Repaglinide and nateglinide Pioglitazone Acarbose Sitagliptin Exenatide
Repaglinide and nateglinide
- nonsulfonylureas
- that act on a portion of the sulfonylurea receptor to stimulate insulin secretion.
Pioglitazone
- thiazolidinedione, which reduces insulin resistance.
- activation of PPAR-Y, a receptor that affects several insulin-responsive genes.
Acarbose
- competitive inhibitor of α-glucosidases, enzymes that break down complex carbohydrates into monosaccharides.
- This delays the absorption of carbohydrates such as starch, sucrose, and maltose, but does not affect the absorption of glucose.
Sitagliptin
- DPP-IV inhibitor
- inhibits the enzyme responsible for the breakdown of the incretins GLP-1 and GIP.
- Exenatide
- incretin mimetic
- stimulates insulin secretion in a glucose-dependent fashion, slows gastric emptying, and may promote satiety.
best initial imaging study for acute pelvic pain in women is
transvaginal ultrasonography
Serum uric acid levels with Thiazides versus losartans.
hydrochlorothiazide-increase serum uric acid levels
Losartan has been shown to decrease uric acid
child’s hand is suddenly jerked up
Nursemaid’s elbow
forcing the elbow into extension and radial head slips out from the annular ligament.
Management of acute asthma exacerbations
In children already receiving standard treatment with albuterol and corticosteroids, the addition of intravenous magnesium sulfate has been shown to improve lung function and reduce the need for hospitalization.
Oral administration of corticosteroids is as effective as the intravenous route for reducing the need for hospital admission
