Q

Potassium-sparing diuretics

A

Spironolactone and Eplerenone

Antagonizes aldosterone-specific mineralocorticoid receptors (primarily in the distal convoluted tubule), decreasing sodium and water reabsorption and increasing potassium retention

Q

Celebrex (celecoxib) MOA

A

Selective COX inhibitor that targets COX-2 and has no effect on COX-1 function

Inhibition of COX-2 allows anti-inflammatory action without the disruption of COX-1 (gastric mucosa, regulating renal blood flow, and platelet aggregation)

Q

Ginkgo biloba

A

Herbal supplement that is marketed for the treatment of dementia, memory impairment, and vascular disorders

Potential risk of bleeding due to inhibition of binding of platelet activating factor. (so don’t use with aspirin, NSIDS and anticoagulants)

Q

Unfractionated heparin

A

polysaccharide that binds to anti-thrombin III (AT III) and increases the rate of AT III inactivation of thrombin and Factor Xa

Only in hospital bc it’s given IV

Q

Low molecular weight heparins (LMWH), such as enoxaparin

A

LMWH actions preferentially inhibit factor Xa, with a longer effect than that of heparins. LMWH are administered subcutaneously, but require significant dose reductions with chronic kidney disease

Q

GPIIb/IIIa inhibitors

A

Abciximab (ReoPro), tirofiban (Aggrastat), and eptifibatide (Integrilin)

GPIIb/IIIa receptors are found on platelets. Activation of these receptors leads to platelet aggregation

Q

Aspirin

A

irreversibly inhibits COX-1 in platelets, blocking the conversion of arachidonic acid to thromboxane A2, which is responsible for platelet recruitment and aggregation

17
Q

Hunter Criteria for Diagnosing Serotonin Syndrome

A

Recent use of serotonergic
agent (usually in the past 5 weeks) PLUS
Any of the following:
Spontaneous clonus
Hyperreflexia AND tremor
Muscle rigidity AND hyperthermia (temp > 100.4°F) AND ocular or inducible clonus
Inducible clonus AND agitation OR diaphoresis
Ocular clonus AND agitation OR diaphoresis

18
Q

linezolid is a serotonergic medication

A

Serotonin syndrome typically develops within 12 hours of excess serotonergic agent administration
Hyperreflexia, clonus, hyperactive bowels, and autonomic instability help differentiate it from other differential diagnoses

19
Q

Lumbar puncture shows:

Extremely elevated cell count with decreased glucose

A

Bacterial meningitis

20
Q

Lumbar puncture shows:

Extremely elevated protein with lymphocytosis

A

TB meningitis

21
Q

Lumbar puncture shows:

Increased protein with a normal cell count

A

Guillain- Barre syndrome

22
Q

Lumbar puncture shows:

Normal protein and glucose with lymphocytosis

A

Viral meningitis

23
Q

Adult polycystic kidney disease (ADPKD)- Autosomal dominant

A

Linked to abnormalities on chromosomes 16 and 4

Patients with ADPKD should be evaluated for berry aneurysms with a CT angiogram of the head

Other associations include bicuspid aortic valve, mitral valve prolapse, and aortic dissection.

24
Q

Diagnostic Criteria for Diabetes Mellitus in Adults

A

Presence of symptoms of hyperglycemia: polydipsia, polyuria, weight loss, blurry vision + random blood glucose ≥ 200 mg/dL

25
Q

Diagnostic Criteria for Diabetes Mellitus in Adults that are asymptomatic

A

If the patient is asymptomatic:
Fasting plasma glucose ≥ 126 mg/dL
Two-hour plasma glucose values of ≥ 200 mg/dL during an oral glucose tolerance test
A1C values ≥ 6.5%

26
Q

Diagnosing Central vs Nepphrogenic DI

A

Diabetes insipidus (DI) is due to a deficiency in (central DI) or decreased effect of (nephrogenic DI) vasopressin, leading to polydipsia, polyuria, and hypernatremia. When given desmopressin, a synthetic analog of vasopressin, patients with central DI show improvement, while those with nephrogenic DI show no change. Nephrogenic DI is a well-documented side effect of lithium, which is used to treat bipolar disorder.

27
Q

Treatment for cocaine induced chest pain?

A

Benzodiazepines

28
Q

Phencyclidine toxicity treatment

A

Benzodiazepines

29
Q

Bisphosphonates

A

bind hydroxyapatite crystals in bone and inhibit osteoclast-mediated bone resorption
